[opensuse] dd on an SD card gives: Read-only file system
I have an SD card on /dev/sde. The command "findmnt -l" does not show anything mounted on /dev/sde*'. I am the root user. "ls -l /dev/sde*" shows: brw-rw---- 1 root disk 8, 64 Feb 1 13:43 /dev/sde brw-rw---- 1 root disk 8, 65 Feb 1 13:43 /dev/sde1 So apparently the device is writable. I checked the lock switch on the SD card which is unlocked. After that I want to write an image on the SD card using dd with of=/dev/sde, however I always get: dd: failed to open ‘/dev/sde’: Read-only file system I am using openSUSE 13.1, which is fully updated. When I mount the SD card, which is mounted as a vfat device, I am also unable to write on the device. Any suggestions? -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The physical SD card lock is probably toggled on.
I already wrote that and I checked it (double). However, I have a USB device that takes an SD card and together it is a USB stick. Using that I used kpartionmanager to check the vfat32 partition, which gave an error. However I used the application to write a new partition table on the SD card and after that I was able to use dd to write my image to the SD card in the USB device. After writing a new partition table on the SD card, I still could not write to the SD card with the SD interface in my system. When I insert the SD card in the SD interface device, I can read its content OK, however I can not write to the device.

It is sounding like a kernel driver issue to me. Either you have a unsupported device, or there is a bug. In this case the "device" I'm talking about is the multicard reader, not the actual SD card. I'd open a bugzilla, but it might take a while to get that resolved. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I have an SD card on /dev/sde. The command "findmnt -l" does not show anything mounted on /dev/sde*'. I am the root user. "ls -l /dev/sde*" shows: brw-rw---- 1 root disk 8, 64 Feb 1 13:43 /dev/sde brw-rw---- 1 root disk 8, 65 Feb 1 13:43 /dev/sde1 So apparently the device is writable.
Permissions on device nodes are not related to whether physical device is writable or not. They simply control who is allowed to open device node with intention to write. If permissions do not allow, such open would fail even before attempting to touch device, that's all.
I checked the lock switch on the SD card which is unlocked. After that I want to write an image on the SD card using dd with of=/dev/sde, however I always get: dd: failed to open ‘/dev/sde’: Read-only file system I am using openSUSE 13.1, which is fully updated.
When I mount the SD card, which is mounted as a vfat device, I am also unable to write on the device.
Which strongly suggests that your card for some reasons is read-only.
Any suggestions?

do you mean you used findmnt *after* mounting the card? do fdisk -l show the card? or fdisk /dev/sde?

You'r welcome.
then did you notice /dev/sdx is *not* a mount point, but a device?
of course.
When I mount the SD card, which is mounted as a vfat device, I am also unable to write on the device.

I did both. I just wanted to explain that the device was not mounted when I tried to write the image to the device using dd.
do fdisk -l show the card? or fdisk /dev/sde? It's unsual to have a file system on a raw non partionned device (even if it should be allowed)

good. How did you mount them, with command line or with dolphin? (the mount point is unusual) can you mount any on /mnt, if necessary as --bind, to see if the permission probem can be excluded? problems mounting windows partition is often due to a bad umounting (from windows). The only fix I know is to mount them again *in windows* and umount them cleanly, it needs sometime *minutes* to have the file system umo_unted really and be able to remove the card from the computer there should not be any problem with ext2, beside an eventual fsck I forgot to ask what the dd copy is. did you already did it or do you want to do it now (like it seems through the subject)? I beg if you want to dd *to* the card, it's content is not important, so can you modify it in any way (fdisk, mkfs, rm)? did you try imagewriter(from opensuse)? not that this should change anything :-) jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

I used Dolphin, which means it is mounted like above.

I can and when I do I get: # mount /dev/sde3 /mnt mount: /dev/sde3 is write-protected, mounting read-only The fact that the device is write-protected, is the problem. The SD card is not write protected. So how can I make the device /dev/sde3 not write- protected or rather /dev sde when I use dd to write an image to the device.

It has never been used on a Windows machine. The SD card is used to boot from by a Raspberry Pi.
there should not be any problem with ext2, beside an eventual fsck

No. The problem is that somehow the device is defined as read-only. Maybe something in udev that does that. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

The fact that the device is write-protected, is the problem. The SD card is not write protected.
when I insert a write protected card I get in dmesg: [ 1365.057433] sd 8:0:0:0: [sdf] 15523840 512-byte logical blocks: (7.94 GB/7.40 GiB) [ 1365.058534] sd 8:0:0:0: [sdf] Write Protect is on [ 1365.058537] sd 8:0:0:0: [sdf] Mode Sense: 03 00 80 00 [ 1365.059521] sd 8:0:0:0: [sdf] No Caching mode page found [ 1365.059524] sd 8:0:0:0: [sdf] Assuming drive cache: write through [ 1365.062268] sd 8:0:0:0: [sdf] No Caching mode page found [ 1365.062270] sd 8:0:0:0: [sdf] Assuming drive cache: write through [ 1365.075964] sdf: sdf1 So how can I make the device /dev/sde3 not write-protected or rather /dev/sde when I use dd to write an image to the device. did you try an other card? just in case it's the reader that have a problem? some are mechanics, some are optics and may be can be dusty?
It has never been used on a Windows machine. The SD card is used to boot from by a Raspberry Pi.
is there a format option in the rapsberry or is it completely empty?
No. The problem is that somehow the device is defined as read-only. Maybe something in udev that does that.
most real problems are hardware related. I would try usb flash disk or external card reader you can also boot a live system and see if it's better, and if yes, try an other user created for this purpose jdd -- http://www.dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Putting a tape on the notch at the other side of write-protect switch on the SD card did not help. I am afraid it is build into the Realtek device.

Not necessarily true. Very unlikely if any other media is not also write-protected. It seems more likely that the media's controller firmware is buggy and somehow flipped the write-protect bit during the write process. There is a possibility that some of the data being written to it was interpreted as a command to flip the write-protect bit. You can try flipping it back with a utility that can send commands to the controller or copy the data to a new device from a different vendor and hope none of it is again interpreted as commands. No idea where to find such a utility but they do exist. It's likely much easier to just replace it. jd -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
