Not allowed to open disk

[firenice03]

Some added info - this may help those who may be looking on..

Is this the same disk that LL is installed? or is this a secondary "data" disk?
How was it added?
- Was the disk there during install or added after the fact? Was the disk "removed" either physically or via commands (if so what?)


How was this disk formatted - # partitions and Format (NTFS/EXT4 etc) is it an LVM?


Did you during the time the disk was mounted, set up or add disk encryption?


Is this an internal (SATA) or external (USB) connected disk.
Have you tried mounting the disk as a USB (mass storage) device?



perhaps posting the output of the..

Code:

lsblk
sudo fdisk -l

Maybe worth a check if UUID's match if it was added to fstab

Code:

cat /etc/fstab
blkid

As much info as you can provide about the disk/system will ensure those to help have the necessary info..
