I am currently trying to recover a hard drive I accidentally formatted, but am of course, using
dd if=/dev/sdb of=/dev/sdc conv=noerror,sync to make a backup to work on first. I have two questions, actually.
dd is sloooooooowwwwww. My partition table and file system are damaged from the accidental format, if I use a larger block size via
-bsoption, would this somehow affect the drive geometry of the copy?
Since it's bit to bit and I'm only working with the partition table/file system which are at the start of the drive; if I need to re-copy the original drive to the backup, can't I just abort dd after the first few MBs, since the rest of the drive should remain unchanged?
I'm hoping one of these is a yes, otherwise I've got about ten hours to go.
