[SOLVED]Unable to recognize external HD

[mbnoimi]

Hi guys,

LM suddenly stopped seeing my external seagate HD (4TB) although it's available in fdisk and other apps!

May I get your help please?

LM 17.1 xfce x64

Code: Select all

sudo fdisk -l

This doesn't look like a partition table
Probably you selected the wrong device.

   Device Boot      Start         End      Blocks   Id  System

Partition table entries are not in disk order

The partition table is corrupted. You might try to recover it using testdisk program, install package testdisk first.

Sorry for silly question, Is there any GUI for it? I'm very suspicious of CLI apps for manipulating partitions

Thanks a lot for suggestion, I fixed this issue as mentioned above.
