Suddenly I got a problem on a iomega mini usb drive, that worked OK
for long time.
Inserted the new drive is immediately seen and assigned a letter "X".
If I click on it, I get an error message "insert a disk in the "X"
unit".
I tryed almost everything as my first thought was that the partition
data has been for some reason, corrupted.

1) Same result got on different PC
2) Same result got if I insert the flash before or after the boot.
3) Of course I cannot reformat as the unit is recognized but the
volume/disk is not.
4) I downloaded several software claiming to recover, format,
partition etc USB devices but : no result.
5) Partition Magic 8 doesnt see the drive, only fixed disks
6) Read everything I could find on MS Support, On Google , on Groups
etc.
7) No possibility to reach the storage for a low level formatting.

This is my last attempt, if someone of you has another idea !
After I will go to buy a new drive !!

Thanks
Manlio
