This same USB drive used to show up on the desktop and in the file list. My Ipod shuffle will show up now but not this very important usb drive. I would really appreciate some help and please don´t tell me that I have to format it without recovering my data (life).

You broke it, you keep the pieces.

Check if /dev/sda (without the "1") exists. If yes, you can in the 
meantime dump your device contents bit-by-bit in a file, for further 
recovery, regardless of the filesystem having gone awry:

dd if=/dev/sda of=backup.dat bs=512

Then, you can try to recover your filesystem using your backup.

However, it is not stuff for the faint of heart. You can read a 
description here of what black magic it can involve:

This utility could perhaps help (never tried it myself):

Best of luck!
