[opensuse] Actual capacity of SDXC cards
I bought some 32G micro SD cards on eBay, and on advice I check to see if they were all actually 32G. There's a program available under Linux called "f3". I'm running 3.5.0 http://oss.digirati.com.br/f3/ What it does is write a pattern, step and repeat To quote from the man page <quote> F3 (Fight Flash Fraud or Fight Fake Flash) tests the full capacity of a flash card (flash drive, flash disk, pendrive). It writes to the card and then checks if can read it. It will assure you haven't been sold a card with a smaller capacity than stated. When writing to flash drive, f3write fills the filesystem with 1GB files named N.h2w, where N is a number (i.e. /[0-9]+/). </quote> The the f3read program verifies. You have control over the starting and ending numbers, so if you think the 32G drive is actually a 8G you can skip the first 6G and just do 7G to 9G. I found that indeed the 32G labelled chips were actually 8G. There's a tool that re-writes the chip ID info and so I made sure that theses 8G chips said they were 8G. And I got my money back. FOSS wins out again. There are free version of similar tools for Windows as well. ------------------- I do however have a question. Running these tests takes a lot of time. I'm wondering if there is a quicker way. I'm wondering if there is a file system whereby the mkfs builds a FS structure all the way down to the supposed end of the media, perhaps some kind of b-tree, then the fsck verifies it actually is what it supposed to be, that if the supposed 32G was actually a 8G and writes wrapped around somehow. checking the (empty, before commuting data) tree structure would show this up and give some clue as to the where? It seems reasonable to me, but a simple fsck fail would not give information on the actual size, would it? Just that the structure was buqqered.

yes
I'm wondering if there is a quicker way.
no. may be run only fo 10Go, as most fakes are 8Go
Any thoughts on this?
the fakes are paginated, so why ordinary write don't works usually only the larger flash drives may be fakes (last one I got was 128Gb) jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

So if I have a supposed 32G I try 7-10, and if that's OK then 15-17 Si 23-25 any use or dothings simply double, an 'extra address line'?

no, you have to cross the boudary - and (I just think) also make more than 8Gb - to have duplicate files. The file just after 8Gb writes on the one at 0, removing it's number

Well those 32g-that-really-were-8g for f3fix'd to say they were 8g and have proven reliable as 8g devices. It hardly seems worth it, though. Not much better than DVDs for nbackup, only use as 'emergency' for my camera.

With an adaptor and USB carrier to the front of my PC, yes speed is awful. Regular readers will recall that i rip my DVDs so that I can put them on these cards and watch them on my tablet in more relaxed circumstances. An 8G card can, if I'm not using it for anything else (as in dedicated swap-out/swap-in mode) I can fit 4, maybe 5, and possible a Youtube excerpt on the 8G cards. But copying from the PC to the card of even a couple is an over-night project. This is a hardware issue, those adapters may be OK for use in a camera and retain speed, but the USB i/f is limiting. And these chaper cards are not blazingly fast. Adequate for extending the phone's memory and for movies and storing text, but not recording streaming video. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Something is wrong, then. They should write at about 10 Mbyte/second.

USB should read/write at 20 MByte/second. If they go at 2MB/S, you have the wrong adaptor: USB 1, not USB 2. It happened to me recently. I noticed that my card reader, cheap, was very slow. I replaced it with a good one from Trascend and the speed increased ten times. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

this in theory. The real speed is always much slower http://dodin.info/wiki/pmwiki.php?n=Doc.MemoryCards#toc5 but it's very difficult to have a true speed evaluation, due to various cache, verification algorithms and so on on don't master. The faster is a true usb3 device on usb3 connector (internal sd cards are mostly awful) but obviously my Canon EOS5DMKIII can write cards much faster than that. I tested with it very cheap cards and they accepted very fast writes for the half an hour the device can write continuously (cinema grade video, I never use this because it fills the card very quickly an quality is more than I need :-)) jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Well WOW , YES! I went out and got a USB3 class reader and even with the older cards and the USB2 slot on the front of my Dell Optiplex 755 desktop its much faster. The f3 text on the first 9 G of a chip runs in about the time it takes to brew a pot of coffee. As opposed to the 4-5 hours it did before. I take it that the motherboard device I see when I run 'lspci' -- Intel Corporation 82801I (ICH9 Family) USB UHCI Controller -- is not a USB3 device. I see some USB3 cards on eBay & Amazon that offer ports at the back of the computer, and seem to offer an internal port. What I don't see is a card that can substitute for the headers on the mobo and let me 'convert' the two front panel USB ports into USB3 or 3.1. Maybe I should just move forward my hopes of replacing the desktop even though there's noting actually wrong with this one and its just techno-lust that makes me want to have a PCI-e connected 256G SSD and all USB3 when all I need it just more memory.

I'm aware of the "double" format https://upload.wikimedia.org/wikipedia/commons/thumb/c/c3/Connector_USB_3_IM... I have that on my 12" Samsung tablet. But that's just one of many USB3 formats. Wikipedia makes it clear that First: "A USB 3.0 Standard-A receptacle accepts either a USB 3.0 Standard-A plug or a USB 2.0 Standard-A plug. Conversely, it is possible to plug a USB 3.0 Standard-A plug into a USB 2.0 Standard-A receptacle. Similar principle of backward compatibility applies to connecting a USB 2.0 Standard-A plug into a USB 3.0 Standard-A receptacle. The Standard-A is used for connecting to a computer port, at the host side." However Secondly: "A USB 3.0 Standard-B receptacle accepts either a USB 3.0 Standard-B plug or a USB 2.0 Standard-B plug. Backward compatibility applies to connecting a USB 2.0 Standard-B plug into a USB 3.0 Standard-B receptacle. However, it is not possible to plug a USB 3.0 Standard-B plug into a USB 2.0 Standard-B receptacle, due to a physically larger connector. The Standard-B is used at the device side." The key thing is that, apart from that new "double" format: "Since USB 2.0 and USB 3.0 ports may coexist on the same machine and they look similar, ..." There should be colour coding indicating the difference. Now what exactly are you talking about? Right now I am using my USB3 SDXC adapter in q USB2 socket and seeing a fantastic speed improvement over one 'fee' one I got with one of those 32G-that-was-really-only-8g chips. I don't have a USB disk drive or USB DVD.

This was not 'testing'. I wasn't interested in comparing it with others, measuring its speed. It was 'validation' -- fit for the intended purpose. The intended purpose was the ONLY thing that mattered, was the reason for the purchase in the first place. I'm not researching for an article!

Actually the phrase "fit for the intended purpose" refers to Consumer Protection legislation in the so-called 'Common Law' countries, that is those that derive there jurisprudence processes from the English traditional rather than from 'Code Napoleon'. It basically means that if something is advertised as being capable of a function (or you determined in communication with the vendor that the item was so capable) and it is not then the vendor is liable for r4stitution of cost and perhaps even damages. 'Damages' meaning costs you incurred because of the shortcoming, for example if it was a safety device and it failed to perform as advertised and you were injured, then the vendor may be liable for medical costs and possibly loss of work. Its what many products have some elaborate EULA verbiage. I'm sure there is similar Consumer Protection legislation elsewhere but I'm not familiar with it other then UK/Canada/USA. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I have to say than such products I buy from china directly on aliexpress, and was refunded without having to resend the device back... so if test is anticipated, only time is lost (due to long time delivery from China to France) I also always notice the seller than I test every buy, and to don't send fake, but they send them anyway, pretending after the protest than they where abused by they own maker, what I don't trust at all, given I always give them the link to the test software, asking them to test product themselves example: https://www.aliexpress.com/item/USB-Flash-Drives-128GB-pen-drive-iron-man-US... this pen drive in 512Gb size is supposed to cost around $17. Then it's said to be USB2. That's simply impossible. Such capacity with USB2 is unusable, and the real price on the same platform is around 300 or 400$ if ever you find one (I only found 256Gb for $150) so it's *obviously* a fake. One can order one to test it, but it's probably only 8Gb, not worth the price :-)) notice the dealer is noted 4.7/5 stars, but only with 6 clients... jdd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Be VERY wary of the above designed thumb drives. Very! I recently bought a 5 pack of these from Amazon, and I ran them through the F3 test suite. 40℅ failure rate. 2 units failed totally. One additional could be used only to 50 percent capacity. The other two actually worked as advertised. Test every unit. Or look for another design. This particular design is sold under a bunch of different names. They are flooding the market with crap. And Amazon isn't helping by having the same drives under a zillion different product ids, hiding the bad reviews under a hundred different rocks. I posted a bad but honest review and got mail from the manufacturer, filtered through Amazon. The offered me another 5 pack free if I would change my review. I never even bothered to reply.
are around $40, ssd

What? Only one pack? The mean buggers! They should have started their biding at 5 packs, perhaps 10.

Amazon, to their credit announced that they have terminated carrying any reviews where the product was provided free by the manufacturer or at steep discount in return for an "honest review". Amazon never made it clear who's idea that was in the first place. I suspect it will simply drive the problem deeper underground. -- Sent from my Android phone with K-9 Mail.

I looked at the idea of getting a cache SSD as a PCI-e card. I looked at this thread on EnhanceIO, bcache and dm-cache and then at derived articles. http://lkml.iu.edu/hypermail/linux/kernel/1306.1/01246.html The idea of a 20G SSD for each of my most used partitions appealed. So I looked ta the prices of 64G PCI-e cards. They were quite reasonable. Hmm, I wondered what 128 and larger cards cost. I was shocked! I ran a DU and found I could fit either my system or my $HOME (without music or videos) on a 120G SSD. YMMV but you should check your own system. Why bother with a SSD cache when the whole system can fit on the SD? Heck, some of the larger sized cards, some of the SATA2 and SATA3 are well priced if tour i/f can handle those speed! It's always been a principle 'speed sells', but every analysis I've seen shows that 'distributed computing' offers more advantages than a drag racer. I just wish the idea of David Cheriton's distributed, sporadic kernel of the V System had caught on.

Found it. https://lists.opensuse.org/opensuse-factory/2016-07/msg00062.html «Please be aware that bcache is not actively maintained by it's original author any more and thus marked as or 'Orphan' in the linux kernel's MAINTAINERS file.

As I said in another posting, yes, I can easily fill, and I'm sure JDD agrees, with video and music and technical books. But your SYSTEM? The OS, the libraries, the stuff under /etc/ and /lib and corresponding stuff under /usr NOT what's under /home/, /var/ /svc, not your web site, not you development tree and sources and 'projects. Not the replicated images of repositories. No copies of the ISOs of a variety of releases. Not the stores for various VM images.

I'm not arguing with that. I've made the case elsewhere, repeated so, that given enough memory to avoid code paging/swapping, that the RSS is adequate (often barbecue of good module design and a good link editor) that data, because it's streaming or if, for example, the sidecar files have to be sync'd often without disrupting the workflow, that a high speed DATA partition makes more sense than high speed OS. After all, the code-base is often stable. I run up the OS;/ Usually I turn the machine on while on the way to the bathroom when I wake so how fast it boots isn't critical. When I'm up and running I have a few long lived programs, the X server, a xterm, Thunderbird, Firefox. I have enough memory that the core code-base for those forms the RSS. Its the data that takes up 'dynamic' & pageable memory pages, and even then Thunderbird and Firefox are network programs, they just need space to do their rendering. Most of their demand goes to the OS for network services. So what's the breakdown of my disk? * The RootFS I chose to include /usr but not /boot * /boot * /usr share I separated this out thinking that one day I'd NFS share this ... So I have df -h / /boot /usr /usr/share Filesystem Size Used Avail Use% Mounted on /dev/mapper/vgmain-vROOT 20G 8.8G 11G 45% / /dev/sda1 1.9G 299M 1.5G 17% /boot /dev/mapper/vgmain-vROOT 20G 8.8G 11G 45% / /dev/mapper/vgmain-vUsrShare 5.0G 2.4G 2.7G 47% /usr/share So I could put that part of my SYSTEM on a 32G flash card or something that is not 'rotating rust'. Low latency. For the most part its not something that gets written to ... much. I then have * /home Of course. And there are a number of mounted FS under ~anton for movies, photographs, music and books * /usr/local so that it can survive updates :-) * /srv That's where all the web stuff lives * /opt I treat that rather like /usr/local but its a bit more 'experimental whereas /usr/local is serious, ling term installs with proper libraries and documentation * /tmp If I had a 120G or larger SSD I would have no hesitation about putting /tmp there and making more use of memory based 'tmpfs', perhaps for some of the caches. I might even rearrange /home/anton so a few more things were in separately manageable FS and put /home on the SSD. The point I'm trying to make here is that the really big stuff I have is manageable because its on a separate file system from the SYSTEM. I could have an enormousness set of movies, music, video, web site material and it isn't on the same FS as the SYSTEM. As it stands, even the things that are ENORMOUS on my system, mainly the ~/Photographs tree, is partitioned in a way to ease archiving and backup. I could, for example, free up a lot of space by off-lining everything before say, 2015. its still out there on generational DVDs. Similarly the email I chose to archive, which isn't a lot, comparatively speaking, but does add up over the years. But data is not SYSTEM As someone once said, "Code is Code and Data is Data and ne'er the twain should meet". Well, yes. there /etc and all the config stuff that can be viewed a 'data'. But config is tightly coupled with code whereas real data isn't. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, in my desktop machine. Four hard disks. Originally 500 GB each. Now two are 2000GB, one 3000GB. One 500, which I had forgotten, apparently. Plus 3 external SATA cables. One SATA caddy that doesn't work, reason unknown. I don't think it is the cable.

WOW! That's some pretty cool technology to get a thin piece of rotating rust to fit in the slot on my tablet. Right now, the 64G chip is a little over half full; by the time I've converted all my DVDs and all my CDs I'll need a larger one. But that's just consumerland. The future applications of tablets in medicine and engineering and finance are going make them into not just Tricorders but will demand not only LAN/hospital/clinic level network access but will need their own on-board databases and reference libraries. In engineering there are already applications where a tablet and a a google-glasses like HUD visualizations for maintenance in areas where there is no network, and have a huge set of engineering diagrams, maintenance manuals for all the possible equipment and scenarios. We got a hint of that in Michael Creighton's "Airframe" novel years ago. q.v. 640K wasn't enough. When Bill Gates said that in 1981 I had already been running UNIX variants on 16 bit microprocessors for nearly half a decade. Although there were quite a number of firms that had produced UNIX systems based on the Zilog/AMD Z-8000 before that date, SUN was founded in February 1982, put the idea of a UNIX workstations into high gear and was profitable by July 1982. How many start-up can claim that kind of rise and the subsequent presence and enduring 'image'? 8g isn't enough. Local banks here were giving away 'crippled' Android tablets with only 8G of memory free when you opened an account. Many people brushed them off; their phones had 'large enough' screens, were pocketable, and had twice as much memory. Now phones seem to be normalizing at 32G. It said something about the comparative cost of memory. While the s/h market is overloaded with these devices they aren't completely useless.. I know a guy who buys them up, strips them and installs them in cars, not just as dashboard devices but in the back of head-rests as 'entertainment devices' for the back-seat passengers. The lack of memory doesn't matter as they are wire-networked to the console which has, among other features, a DVD player. This started, for him, as a home project, but a fried saw it and said 'cool' and word got out. It's now a business and on a larger scale. There are other uses for these old junkers. You can see a variety of 'maker' projects from things like front door camera&screen with wifi so that you can view callers on your phone even if not in the house, through to adding sophisticated 'control panels' in all manner of devices making them very sophisticated "IoT" things. Somewhere along the line you main phone in your pocket is now a command centre. its going to need more and more capacity, that is memory; We've already got plenty of CPU power. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Yes, there are, but a recording image device has to be registered and follow rules from the data protection agency. I do not have clear the regulations, if you ask google you find lots of contradictory advices. There are door cameras on sale, to see who is outside the door, calling. But they can't record, just display. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

There is no doubt that there are many vendors on AliExpress and eBay selling larger capacity cards or sticks that are 'fakes' or unreliable. That does not mean that *all* such manufacturers are in that class. *R*E*A*L* SanDisk devices work. But there are counterfeits that appear under that label! They are not genuine SanDisk https://www.youtube.com/watch?v=ZvKdo9UI-OQ Ditto *R*E*A*L* Kingston. https://www.youtube.com/watch?v=43hEDFg9vTg Sadly, _consistently_ telling the difference in on-line adverts is not easy. While there are examples given in differences in packaging, these too change. ultimately you buy, you pay, you test, and if the test fails you complain and ask for a refund. BTDT with a 32G that was an 8G purchased on eBay. Thanks to eBay's policy I go my money back, but I now see some vendors with ambitious wording. For example, at http://www.ebay.ca/itm/512GB-Micro-SD-HC-Card-Adapter-Class-10-Universal-TF-... it says <quote> 2. 100% 16GB/32GB/64GB/128GB 256GB 512GBHuge Storage Real Capacity </quote> That _could_ mean its whatever size they decide to ship you regardless of how its labelled. -- A: Yes. > Q: Are you sure? >> A: Because it reverses the logical flow of conversation. >>> Q: Why is top posting frowned upon? -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

in France, what is important is where the camera looks at. You can't look at your neighbor or at the street at large.

Right, that is what I suspect is the de facto rule everywhere. I know there are places where you have to advertise that "you're on camera" by putting up a sticker etc., but when Google can get away with pixelating faces and license plates for public recordings, surely the rest of us can record whatever we want on our _own_ property for our _own_ use. -- Per Jessen, Zürich (6.9°C) http://www.dns24.ch/ - your free DNS host, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

More to the point, does "at your front door" or "inside your front porch" qualify?

I think so, inside the house. But visitors need to be warned. The problem is, I believe, recording and controlling access to the recordings. I installed a security alarm system, and I know that I had to sign a paper that was given to the police. A friend that should know says that this is an exaggeration by the security company to make people believe that they can't install cameras inside. So, I'm confused. -- Cheers / Saludos, Carlos E. R.

Alarms cause problems for police. They usually are the ones responding to these, if not due to direct notification, then due to the noise complaints.

Yes, but it is not the case. The "alarm bell" is internal to the house, not external. The police is not "alarmed", unless the control center decides that the incident is real and calls them. -- Cheers / Saludos, Carlos E. R. (from 13.1 x86_64 "Bottle" at Telcontar)

I don't have clear the regulations. Google and fora have contradictory advices. The problem is in storing the images. You need to have a notice indicating the presence of cameras. A visitor to your house or garden has to be aware of the cameras. The recordings have to be completely destroyed within a short time, perhaps two weeks; I suppose not so if there is an actual crime recorded. If you have recordings you need to prove how you protect the recordings so that only authorized people can get them. I don't really know. Complicated. -- Cheers / Saludos, Carlos E. R.

Just my experience - I've been using a Kingston 128Gb card in my camera for about two years now, no problems. It also works fine in my laptop (with openSUSE 12.3). For music in my car, I bought a 64Gb USB "stick" (it's tiny). It's much too big of course, but it works fine in the car as well as in the laptop.
