I have a computer with a 1TB internal drive which has always had Windows 10 running on it. Part of the disk is split into the C: and D: drives used by Windows. These have the names of Windows and LENOVO respectively. For a couple of years now I have also had Ubuntu dual booting on it, and have had no issues accessing the "C" and "D" drives from Ubuntu. Having recently upgraded to Ubuntu 23.10, I can't access the "D" drive any more, but "C" access is fine. When I try to mount "D" I get an error " Error mounting /dev/sda4 at /media/chris/LENOVO: wrong fs type, bad option, bad superblock on /dev/sda4, missing codepage or helper program, or other error"

Using Disks, I've checked the mount options for C and D and both are identical ( nosuid,nodev,nofail,x-gvfs-show ), and both use NTFS.

When I boot into Windows I can access both drives fine. USB drives work fine under the new Ubuntu version.

Any ideas ?

  • https://askubuntu.com/questions/1489733/23-10-cannot-mount-usb-key This sounds similar. Have you tried running a chkdsk /F /R in Windows on the drive? – moo Nov 26 '23 at 20:31
  • Hello moo, thanks for the suggestion, indeed the CHKDSK /F /R did work, even though it found no issues with the D: drive. Very odd, but thanks, I can now access the D: drive from withing Ubuntu as before. – ChrisS Nov 28 '23 at 09:49

The Linux NTFS driver can be more particular about a clean error-free drive than the native Windows driver. To check the drive for errors and attempt to correct any that have been found, it's best to use the native Windows chkdsk utility.

Important command line switches for chkdsk:

/F
Fixes errors on the disk

/R
Locates bad dectors and recovers readable information

From within Windows, try:

chkdsk /F /R driveletter:

If you don't have a native dual-boot Windows system, you can do this from within a virtualised copy of Windows if you set up your disk for raw access
