Having seen this situation in the past on one or two of my machines, I'm going on record saying its the drive, not the port. Serious problems with drives will freeze the port so the kernel decides something hast to be reset. I've had this happen with disks having heat problems, but most often with disks that were just flat failing.

From the kernel's perspective all it can see is the buss or port so that's what it diagnoses.

It is possible. If the OP can test with another disk, that would clinch it. I wonder if an SMART test would say anything? Perhaps with the manufacturer disk test utility.

At the moment, I can't get another disk, although that may have to change... I was wondering, though, if there were a test I could run, perhaps chkdsk. You mention a SMART test. I'll have to go look for that. I'll add two things to the mix now: I'm using the 915resolution utility on startup as the laptop has an Intel 935 graphics chip. Matt Archer mentioned a possible graphics problem, so I think that's worth checking. The second thing is that when the computer freezes the clock continues and I can move the mouse pointer around the screen. Nothing else can be done, though. There's a system rescue disk on Distrowatch. Would it be an idea to get this and use it to test the hard drive? Ultimately, I suspect the best solution is to get a new hard drive and store the old one in case I ever sell the computer. I don't actually use the Microsoft so it wouldn't be missed.

Yup. In fact, disks are so cheap now that when I order a new machine I just get the smallest disk offered, and remove it immediately and replace it with a separately purchased compatible drive of the size I really want.

Why would you *replace* it? The more disk drives you have, the less I/O wait time, resulting in significant improvements in performance, especially with interactive processes. The desktop machine I'm on right now has SIX disk drives in it. And with your filesystems spread over a bunch of small drives, they last a LONG time. Even my cheap WD and no-brand IDE drives last for 5+ years... and by the time one fails, all I'm using it for is /tmp or swap.

If any problems develop with the machine I smack in the old drive and ship it back for warranty repair. After the warranty expires, I use the old 40gig (or what ever) in an expansion cabinet for backup, or for fixing other machines that had drive problems.

No, swap doesn't affect this. The improvement is not simple to measure, and depends on the configuration and usage. For instance, if you use lot of local data in /home, and you put home on a separate drive, you get some advantage. But if the programs are already loaded in memory, there is no advantage. It is not so simple. On old, slow computers it is easier to see. For instance, /usr and /opt on different drives speed up the initial startup. - -- Cheers, Carlos E.

It works while you work. You can remain in level 5. System may get slow at times, of course, because the disk will be busy. The test is run by the disk firmware transparently to the cpu or OS (the disk then must have a small cpu, I guess). If you trigger a short test, the output message should tell you an estimate of the time it will take (a minute or two). If you run "smartctl - --log=selftest /dev/sda6" it will report the amount of test it has run already, or done. Actually, when done it doesn't say much more than good or no good.

Actually it is start/stop cycles that carry the most potential for damage.

It doesn't matter if you spin down the disk if you still do the same amount of disk-head movement per day.

Also, when you spin down the disk, the head touches the platter and suffers friction both while coming to a stop and while starting up. The whole time the disk is spinning, the head never touches the platter but floats on a film of air. Also, all electrical circuits suffer a surge when going from off to on, that they don't suffer while merely on, and that surge is worse than some large number of hours or days of coniuous "on", so that is yet another way that spinning up/down produces more wear than merely being on continuously. Similarly but to an even larger extent, the main motor works a lot harder to spin a drive up than to maintain it's running rpm. That translates to higher current oing through various parts of the motor coils and the driver circuit, which means heat and/or chance of burnout of some part. I can very easily imagine that modern drives will last longer if running continuously for 5 years than if spun down 10 times a day and asleep 8 hours a day for 5 years. Fans last a lot longer when they are spun down because their bearings are garbage compared to whats inside a disk, the balance of the impeller is garbage compared to a disk platter, and a disk is a sealed pristine environment while a fans bearings are hardly protected at all. That little sticker on the back means nothing, dust gets in though the other side under the impeller quite readily. -- Brian K.

Apparently Discovery Channel, National Geographic Channel, The Science Channel, The History Channel and those carrying similar programming have conspired to prevent us from learning that the Arctic ice is no longer disappearing, Antarctic ice shelves are no longer falling into the ocean, Greenland's ice is no longer melting, and disappearing glaciers have stopped disappearing.

I don't think this is so with newer hard drives - I believe most now "park" the heads off to the side. Performance-wise, one would be much better off with one fat SATA hdd vs. many small disks. Not to mention the power savings...

Wrong. More spindles = better performance. With a single disk, two files being read or written in parallel will result in the read/write head bouncing back and forth all over the place carrying out the two operations. With two disks, if the files are on different disks, then the two I/O operations can be executed in parallel..with each read/write head moving only as required for the processing of that one file -- rather than frantically doing both.

That "IF" is a pretty big IF.

Not at all. This is especially true during system boot-up, once you've got programs in /usr being started, with libraries in /lib being loaded, for instance

There is really no way to plan this ahead of time to have files spread around optimally.

Of course not, but you CAN take advantage of the general effect.

Further, improvement in speed attributable to subdivision of storage among multiple spindles is easily out performed by just adding memory and allowing the operating system's caching technology handle the work.

Thats why my money goes into memory, not CPU speed.

In fact the only time this fails to be faster is on really huge files, or where you have to read EVERY file, and even then, unless you can arrange EVERY OTHER file read/write to be on a different spindle you are deluding yourself if you think its really faster.

Or when you just plain old have a lot of I/O going on in some area of the filesystem. All I/O on other disks will be spared the interference.

That HD has 22649 power on hours, and is still good.

I must be missing something. 22649 / 24 / 365 is only 2.58550228311 years. Let us know when it passes the greater of its warranty period or 43800. :-p I prefer to transfer non-SCSI 24/7 drives to duty in some non-24/7 box after 2-3 years to reduce risk of data loss.

It is not continuous use. I bought it with the machine around the end of 2001, I think. - -- Cheers, Carlos E.

Some people have good HD luck. The rest of us have to buy new HDs the month after the warranties expire, if they last that long, even without packing a bunch of them together in a hot box like so many cigarettes polluting the planet.

That's only three years. /dev/sda-d are SCSI disks. sda was purchased in 2000, sdb I purchased in 2002 or 2003. sdc and sdd I recently purchased used...but it appears that they are approximately the same age as sdb. sde and sdf are IDE disks. Because it is the oldest, sda is used for /tmp and swap. # smartctl -A /dev/sda smartctl version 5.37 [x86_64-suse-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Elements in grown defect list: 0 # smartctl -A /dev/sdb smartctl version 5.37 [x86_64-suse-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Current Drive Temperature: 32 C Drive Trip Temperature: 85 C Manufactured in week 20 of year 2001 Recommended maximum start stop count: 10000 times Current start stop count: 216 times Elements in grown defect list: 4 # smartctl -A /dev/sdc smartctl version 5.37 [x86_64-suse-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Current Drive Temperature: 25 C Drive Trip Temperature: 65 C Manufactured in week 03 of year 2001 Recommended maximum start stop count: 10000 times Current start stop count: 164 times Elements in grown defect list: 0 # smartctl -A /dev/sdd smartctl version 5.37 [x86_64-suse-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ Current Drive Temperature: 26 C Drive Trip Temperature: 65 C Manufactured in week 27 of year 2001 Recommended maximum start stop count: 10000 times Current start stop count: 60 times Elements in grown defect list: 0 # smartctl -A /dev/sdf smartctl version 5.37 [x86_64-suse-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 16 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 200 200 051 Pre-fail Always - 0 3 Spin_Up_Time 0x0003 180 176 021 Pre-fail Always - 1958 4 Start_Stop_Count 0x0032 100 100 000 Old_age Always - 0 5 Reallocated_Sector_Ct 0x0033 198 198 140 Pre-fail Always - 16 7 Seek_Error_Rate 0x000e 200 200 000 Old_age Always - 12 9 Power_On_Hours 0x0032 098 098 000 Old_age Always - 1725 10 Spin_Retry_Count 0x0012 100 253 000 Old_age Always - 0 11 Calibration_Retry_Count 0x0012 100 253 000 Old_age Always - 0 12 Power_Cycle_Count 0x0032 100 100 000 Old_age Always - 50 192 Power-Off_Retract_Count 0x0032 200 200 000 Old_age Always - 47 193 Load_Cycle_Count 0x0032 200 200 000 Old_age Always - 50 194 Temperature_Celsius 0x0022 114 104 000 Old_age Always - 29 196 Reallocated_Event_Count 0x0032 194 194 000 Old_age Always - 6 197 Current_Pending_Sector 0x0012 200 200 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 200 200 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0008 200 200 000 Old_age Offline - 0 # smartctl -A /dev/sdg smartctl version 5.37 [x86_64-suse-linux-gnu] Copyright (C) 2002-6 Bruce Allen Home page is http://smartmontools.sourceforge.net/ === START OF READ SMART DATA SECTION === SMART Attributes Data Structure revision number: 10 Vendor Specific SMART Attributes with Thresholds: ID# ATTRIBUTE_NAME FLAG VALUE WORST THRESH TYPE UPDATED WHEN_FAILED RAW_VALUE 1 Raw_Read_Error_Rate 0x000f 112 095 006 Pre-fail Always - 213071147 3 Spin_Up_Time 0x0003 098 097 000 Pre-fail Always - 0 4 Start_Stop_Count 0x0032 100 100 020 Old_age Always - 51 5 Reallocated_Sector_Ct 0x0033 100 100 036 Pre-fail Always - 0 7 Seek_Error_Rate 0x000f 078 060 030 Pre-fail Always - 73395546 9 Power_On_Hours 0x0032 099 099 000 Old_age Always - 1720 10 Spin_Retry_Count 0x0013 100 100 097 Pre-fail Always - 0 12 Power_Cycle_Count 0x0032 100 100 020 Old_age Always - 51 187 Unknown_Attribute 0x0032 100 100 000 Old_age Always - 0 189 Unknown_Attribute 0x003a 100 100 000 Old_age Always - 0 190 Temperature_Celsius 0x0022 072 060 045 Old_age Always - 622329884 194 Temperature_Celsius 0x0022 028 040 000 Old_age Always - 28 (Lifetime Min/Max 0/21) 195 Hardware_ECC_Recovered 0x001a 068 057 000 Old_age Always - 158707375 197 Current_Pending_Sector 0x0012 100 100 000 Old_age Always - 0 198 Offline_Uncorrectable 0x0010 100 100 000 Old_age Offline - 0 199 UDMA_CRC_Error_Count 0x003e 200 200 000 Old_age Always - 0 200 Multi_Zone_Error_Rate 0x0000 100 253 000 Old_age Offline - 0 202 TA_Increase_Count 0x0032 100 253 000 Old_age Always - 0 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
