Re-partition USB drive and undo 'dd'

idk666 · 10-18-2006, 02:14 PM

I recently used dd to put an OS image on a usb drive:

dd=if/home/me/disk.iso of=/dev/sda

Now df reports that the disk has only 699M of space and I can't remove the ISO files (even as su) or create new recognisable partitions with fdisk..

I obviously completely stuffed this up somehow. Is there a way to mass reformat the disk and claim back the 19G or so of space I lost ?

Thanks in advance for any help

You destroyed the partition table. Use fdisk or cfdisk to create a new one. Make sure you do this on the external drive!

How do I create the new table exactly ?

Thanks !
