[TriLUG] Backup on USB HD lost

[Victor Snesarev]

I was overhauling a server at home, so I backed up all needed data onto 
a USB-connected hard-drive. I checked that everything I needed was on 
that drive, and proceeded to install Slackware formatting all the drives 
except the USB-connected HD.

When Slack was up and running I mounted the USB drive with

mount -t auto /dev/sda1 /mnt/usbdrive

and the backed up data is gone. There is a lonely "lost+found" directory 
and that is it.

I am not 100% sure about this, but I thought the USB drive was formatted 
with XFS:

mount -t xfs /dev/sda1 /mnt/usbdrive

returned an error saying "wrong fs type, bad option" etc. The 
auto-detect thought it was ext3.

Does anyone know what could've happened and what to do about this? I am 
running "foremost" now on the drive that was formatted during Slack 
install, but I doubt I can get all my data back that way.
