I have a hdd attached to my server. It’s sda but has 2 partitions so sda1 @16M and sda2 @3.6T
It defaulted to being in the location /media/devmon so I kept that and it worked for ages.
Suddenly the data is gone.
I had files located here: /media/devmon/4tb_drive/kiwix/zim and that directory is now empty.
But I put the drive into a Windows box, and everything was there.
When I run mount /dev/sda2 /media/devmon/ it says:
The disk contains an unclean file system (0, 0).
Metadata kept in Windows cache, refused to mount.
Falling back to read-only mount because the NTFS partition is in an
unsafe state. Please resume and shutdown Windows fully (no hibernation
or fast restarting.)
Could not mount read-write, trying read-only
I originally formatted this drive in Windows, is that the issue? Ideally I’d use btrfs or zfs not ntfs, but here we are.
How do I get access again?
If you really need the data on it, get another disk and make an image of the failed drive asap.
If not, skip that step.
See if testdisk can detect your partitions and read data from them.
It is NTFS after all, support has been flaky over the years. Are you running modern Linux NTFS drivers? If there’s no other messages and chkdsk repair (on Windows) doesn’t fix it I would assume the filesystem is alright and look at trying different NTFS drivers versions on Linux.
Have you verified that Windows can actually read all of the files? It may show them and not be able to read some of the files if the filesystem is corrupted.
Did you perform a full shutdown of Windows (Windows doesn’t fully release the partition on a normal shutdown)?
Read the error and do what it says? Lol
@Dust0741 sometimes this can help -> in a linux console: ntfsfix -b -d /dev/sda1 oder ntfsfix -b -d /dev/sda2.
root@skynet:~# ntfsfix -b -d /dev/sda1
Mounting volume... NTFS signature is missing.

Trying the alternate boot sector

Volume is corrupt. You should run chkdsk.
root@skynet:~# ntfsfix -b -d /dev/sda2
Mounting volume... OK
Processing of $MFT and $MFTMirr completed successfully.
Checking the alternate boot sector... OK
NTFS volume version is 3.1.
Going to un-mark the bad clusters ($BadClus)... No bad clusters...OK
NTFS partition /dev/sda2 was processed successfully.
turned off windows quick start
ran chkdks D: and waited…then shut down and put drive back into linux and reboot.
still no
any ideas? clearly not the larger partition, which is good.
