I'm working on an HP Chromebook kip

When I first installed the sd card, it read as mounted, but I couldn't transfer files to it.

In trying to fix that problem, I managed to unmount it (or so I thought) and that's where I found disappointment.

The current error reads as follows:

Error mounting system-managed device /dev/sda1: Command-line `mount "/mnt/usb-Generic_STORAGE_DEVICE_000000000208-0:0-part1"' exited with non-zero exit status 13: ntfs_mst_post_read_fixup_warn: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument ntfs_mst_post_read_fixup_warn: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument ntfs_mst_post_read_fixup_warn: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument ntfs_mst_post_read_fixup_warn: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument $MFTMirr does not match $MFT (record 0). Failed to mount '/dev/sda1': Input/output error NTFS is either inconsistent, or there is a hardware fault, or it's a SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows then reboot into Windows twice. The usage of the /f parameter is very important! If the device is a SoftRAID/FakeRAID then first activate it and mount a different device under the /dev/mapper/ directory, (e.g. /dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation for more details. (udisks-error-quark, 0)

Any suggestions for fixing the problem, THEN setting it up so I can have permission to access it?

  • Did you check it with chkdsk, what was the result? What is the result of ls -la /dev/sd*, who is the owner? Does this card work in other computers? Do other drives work properly in that reader? – Michael Prokopec Feb 15 at 1:30
  • when I run chkdsk it says command not found (I ran both chkdsk and sudo chkdsk - with the same results) – user336988 Feb 15 at 1:53
  • running ls -la/dev/sd says invalid option – user336988 Feb 15 at 1:54
  • Can you install that disk utility, then attempt to run it? Did you use the asterisk, and space between -la and /dev/sd*? If that still does not work then find out who owns /path/to/your/disk e.g. /media/username/disk. – Michael Prokopec Feb 15 at 1:57
  • I did not. Sorry I missed the space. Here's what it says: chrx@chrx:~$ ls -la /dev/sd* brw-rw---- 1 root disk 8, 0 Feb 15 10:48 /dev/sda brw-rw---- 1 root disk 8, 1 Feb 15 10:48 /dev/sda1 – user336988 Feb 15 at 2:00

I would try this:

sudo dd if=/dev/zero of=/dev/sda bs=512 count=1

Then try to reformat the drive if it works great, if not then the drive is likely defective/burnt out (only if it can not be made to work in a different system as well).

  • l tried. Permission denied. – user336988 Feb 15 at 4:12
  • You need to use sudo or to be root with su. – Michael Prokopec Feb 15 at 4:15
  • It worked! AND I can drag and drop files to it. Thank you very much. That's one more problem solved!! – user336988 Feb 15 at 4:38
  • @user336988 Can you check this as the right answer? – Michael Prokopec Feb 19 at 14:46
