List members,
I'm running SUSE 9.2 Pro... can anyone recommend an app or technique for securely wiping the contents on an external usb hard drive with a single 120GB reiserfs partition?
- unfortunately because of the case design - cracking the case and removing the drive so it can be connected directly to an IDE controller is not an option
- fdisk'ing the drive, just wiping the partition table, reformating, etc. are not sufficient - I need an option that will make the drive's current contents reasonably unrecoverable
- it's been suggested that I repeatedly do "dd i=/dev/urandom o=/dev/sda && dd i=/dev/zero o=/dev/sda" - and I will do this if necessary - but would rather not take the days that this is likely to take
- it's also been suggested to use 'shred' - however, in the man pages for shred is says that because of the redundancies and protections built into the Reiser filesystem - that shed will not truely and securely wipe the files - there is a reasonable chance of recovery after shreddig files on Reiser
Thanks,
Eric
Hi, look for dcfldd. dcfldd is much faster than the "normal" dd. i.e. wiping a 300GB Harddisk will take round about 4,5 h of single pass wiping with dcfldd and about 6 h with the normal dd. Take dcfldd! Regards, Christian
