Can't mount external drive

Support
1

I had a failing 3tb hard drive on a BlackX thermaltake (usb3). I bought a new 4tb hard drive and copied the data to it with a mediasonic (usb2). It took a long, long time…

Now when I try to use the 4tb and place in the blackx thermaltake (usb3) manjaro doesn’t mount the drive.

mediasonic (usb2) it mounts properly

Have a look at this thread…
Mount a external hard drive with execute permissions - #4 by DeLinuxCo

I just did, that doesn’t help.

I just installed gnome-disk-utility: 40.2-1 from extra. and it see the disk as unallocated

on another system I get

Screenshot_20210814_111612
Screenshot_20210814_111612637×501 40.5 KB

Notice the serial number being different but it’s the same drive!

Thanks

Yeah, the serial numbers may be an issue, does the system with the issue have any renmants of the drive in fstab?

5

No, nothing in the fstab. Here it is:

cat /etc/fstab
# /etc/fstab: static file system information.
#
# Use 'blkid' to print the universally unique identifier for a device; this may
# be used with UUID= as a more robust way to name devices that works even if
# disks are added and removed. See fstab(5).
#

That is strange… if you have Gparted, run it, select your drive, then go to Device > Attempt Data Rescue and see if ti finds any issues.

Make sure your data is backed up!

7

How did you “copy” the data? Old fashioned click-and-drag, rsync, cp, etc, or using a low-level tool such as dd?

What do you see after invoking sudo dmesg | tail -n 50 seconds after plugging it in? (The ThermalTake bay with the drive inside.)

EDIT: Upon looking up that USB drive bay, I don’t see any mention of it supporting UAS. You might have to blacklist UAS for that device if that’s the case (or purchase one that prominantly advertises UAS support.)

Whether it supports it or not (most being sold now do), dmesg might clue you into what’s going on.
