I did what you suggested but there were some issues...
First of all, it takes some time until I can see it either on disk utility or gparted.
Code:
thanos@thanos-laptop:~$ sudo hdparm --read-sector 0 /dev/sdc
/dev/sdc:
reading sector 0: FAILED: Invalid exchange
It took some time until I got this result...
Before I do that I run fdisk. While my sda's partitions showed up instantly it took some time for the sdc, with a read error though...
Code:
thanos@thanos-laptop:~$ sudo fdisk -l

Partition table entries are not in disk order
Unable to read /dev/sdc
I also tried to make a partition table from gparted, but I got an error. From what I can understand, when my HDD is plugged in a USB, it takes some time until it is read, it stays there for short time and then disappears. In order to read it again I should unplug it and then plug it again...

I run this, but I got no output...
Code:
thanos@thanos-laptop:~$ sudo sfdisk -d /dev/sdc > PTsdc.txt
/dev/sdc: No such file or directory
sfdisk: cannot open /dev/sdc for reading
EDIT:I unpluged/pluged it and in "disk utility" the HDD showed up as free unallocated space.
I run "fdisk" and now I could see my drive!
Code:
thanos@thanos-laptop:~$ sudo fdisk -l

I run again what you suggested but I got something similar
Code:
thanos@thanos-laptop:~$ sudo hdparm --read-sector 0 /dev/sdc
/dev/sdc: No such device or address
thanos@thanos-laptop:~$ sudo sfdisk -d /dev/sdc > PTsdc.txt
/dev/sdc: No such device or address
sfdisk: cannot open /dev/sdc for reading
I tried to format it in NTFS from "disk utility" but now I got a different error
Code:
Daemon is inhibited
What is this?
Before that I run
Code:
thanos@thanos-laptop:~$ sudo smartctl -a /dev/sdc

Any idea on what's going on here, whatsoever...?
