I am using Lubuntu 16.10 installed on 120 GB drive. However, I also have a secondary 1TB hard drive full of personal data and similar valuable information, yet I am unable to mount it:

jan@Bondy:/$ sudo mount /dev/sdb2 /media/diskD
mount: wrong fs type, bad option, bad superblock on /dev/sdb2,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       doesg | tail or so.

Output of fdisk:

Disk /dev/sdb: 931.5 GiB, 1000204886016 bytes, 1953525168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes/4096 bytes
Disklabel type: dos
Disk identifier: 0xcf802303

Device     Boot      Start        End    Sectors  Size Id Type
/dev/sdb1             2048   32507903   32505856 15.5G 27 Hidden NTFS WinRE
/dev/sdb2        302507904 1953521663 1921013760  916G  7 HPFS/NTFS/exFAT

I am not sure. Is something wrong with my NTFS filesystem? Might I need to format my drive again?

EDIT: After I split C drive into 2 partitions and installed Lubuntu again, the Lubuntu was still unable to load second drive. To the second partition I installed windows, that is able to work with second drive without any problem.

  • A note for the future. Please don't post screenshots of the console unless unavoidable. Instead, just copy-paste the console output into your question directly. – Kaz Wolfe Dec 9 '16 at 18:32
  • Alright, will remember that. – Bondy Dec 9 '16 at 18:34
  • (hunch) I think it might help if you post the output of gdisk /dev/sdb. Maybe is this some kind of hybrid disk (MBR+GPT) and the MBR displayed by fdisk should not be relied upon. – xhienne Dec 9 '16 at 19:36
  • @xhienne GPT fdisk (gdisk) version 1.0.1 Partition table scan: MBR: MBR only BSD: not present APM: not present GPT: not present *************************************************************** Found invalid GPT and valid MBR; converting MBR to GPT format in memory. THIS OPERATION IS POTENTIALLY DESTRUCTIVE! Exit by typing 'q' if you don't want to convert your MBR partitions to GPT format! *************************************************************** – Bondy Dec 10 '16 at 9:08
  • It also might be worth to mention, that when I plugged in a USB, I could find it in /media/jan/(nameOfUSB) without executing any command. And before I installed Lubuntu to hard drive, I was booting Porteus from the USB and I was unable to access the 1TB drive aswell. Even though I could even see it in file manager unlike in lubuntu. – Bondy Dec 10 '16 at 9:22

Apparently, Linux tries with the FS type it has identified and it fails. First let's see what Linux thinks it is:

blkid /dev/sdb2

So, if it says `vfat', then try NTFS:

mount -t ntfs /dev/sdb2 /path/to/mount/point

And if it says 'ntfs', try VFAT:

mount -t vfat /dev/sdb2 /path/to/mount/point
  • Thank you for response. I did the blkid /dev/sdb2. And it writes nothing after executing it... :/ – Bondy Dec 9 '16 at 18:30
  • Strange. Try blkid -p /dev/sdb2. Else you can try the mount commands, it won't hurt. – xhienne Dec 9 '16 at 18:43
  • No output again. When I write just "blkid": jan@Bondy:~$ blkid /dev/sda1: UUID="46e68169-3b5f-4b6c-a135-7db087d5742b" TYPE="ext4" PARTUUID="43ef7791-01" /dev/sda5: UUID="18f0aa03-da81-429d-b698-6f01a43d36b1" TYPE="swap" PARTUUID="43ef7791-05" It does not even list the drive... Maybe I need to download some package? I'm using lightweight ubuntu. – Bondy Dec 9 '16 at 18:55
  • @Bondy No, nothing to install. And the mount commands, what do they do? And the fdisk command in the original post, does it still work? – xhienne Dec 9 '16 at 19:01
  • The mount says it cant be found in /etc/fstab. And it really isnt there. When I use fdisk, it is there. And when I open the Disk software, it is in there.... – Bondy Dec 9 '16 at 19:07
