need help please mounting a Sun Utra 5 Sparc disk drive connected via USB to an Ubuntu VM. This contains Solaris 9 and some files which I haven't accessed for many years. This is what I've done so far:

$ sudo fdisk -l
Disk /dev/sdb: 114.5 GiB, 122942324736 bytes, 240121728 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disklabel type: gpt
Disk identifier: EDA32355-9678-4599-BA3B-76115CCAEF38


$ sudo mkdir /mnt/myusb
$ sudo mount -r /dev/sdb /mnt/myusb
mount: /mnt/myusb: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.


$ sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb /mnt/myusb
mount: /mnt/myusb: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.

Been informed that ufs is most likely the filesystem on Solaris 9.

How do I check if ufs is supported? If it is, how do I mount this drive? Any ideas are greatly appreciated.

    Does Mount UFS filesystem help? Admittedly that is an old question which was about Ubuntu 11.10. – Chester Gillon May 10 '25 at 12:06
  • Hi, unfortunately that didn't work. – John Lyons May 15 '25 at 09:22

  • mkdir /mnt/myusb

    sudo fdisk -l

    Disk /dev/sda: 30 GiB, 32212254720 bytes, 62914560 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0x286343be

  • sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb /mnt/myusb mount: /mnt/myusb: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.

  • sudo mount -r -t ufs -o ufstype=ufs2 /dev/sdb1 /mnt/myusb mount: /mnt/myusb: wrong fs type, bad option, bad superblock on /dev/sdb, missing codepage or helper program, or other error.

    Any ideas please?
