Re: External hard drive with mounting problems

> I have a 250 GB Seagate Expansion Portable Hard Drive that sometimes won't mount. I end up having to use TestDisk to recover my files from it, and then I have to reformat the drive. The drive works for a while, and then it becomes unmountable sometime later. I've had this happen with the drive formatted as NTFS (original) and ext2.

Did your USB cable moved even by mm? I have similar problems with my
external hdd, it is always losing connection when cable is moved even
by 1mm. What you have in your /dev/sd* after lost connection ? ( in my
case sdbX is still mounted, but there is no such thing as sdb* in
/dev/, instead I have sdc which I can mount in exact same place as
sdb, but it just repeating of process )

When I try to mount the drive in a shell, I get an error message telling me that it's not listed in /etc/fstab or /etc/mtab. This is the case whether I try to mount the drive as /dev/sdc, /dev/sdc1, /mnt/sdc, or /mnt/sdc1.

Try mounting sdd1 ( if you don't have any other sdd in /dev/ ) or
whatever it will be

Just strange behavior of mount/kernel/usb external drives/whatever. I
never got to WHAT exactly is happening there.
