For some tests I need to duplicate a corrupted hard drive (the filesystem is corrupted according to reiserfsck). I do not need to repair it but to clone the BAD filesystem structure into other identical HDDs several times. I don't even care about the contents of the files.
This is the problem:
using dd takes hours for a 250GB HDD
using clonemaxx or other software takes hours too
if i duplicate the MBR and the boot record using dd and then run reiserfsck I get as a response that the filesystem is healthy.
Any ideas to have a good supply of identical corrupted hdds without waiting for hours?
Distribution: Redhat 7.3 Valhalla, Solaris 8, HP Tru64

I think dd is the tool you need as it is a byte-by-byte copy.
If it can wait a while, why don't you leave it running overnight and come back to it in the morning?
For reiserfsck they are now identically corrupted. According to what I've read today, I think I copied the superblock, the journal and some of the data... and only took 1 minute. It's going to save me 2h59min per disk.
