Dead hard drive, trying to make the image banal dd. When hard, stumbles upon a bad piece of disk, program, which addressed, hangs for 15 seconds, after which she returns i/o error. During these 15 seconds the drive makes unusual repetitive sounds.


Question: how can I reduce this time? For example, if the block is not readable in a second, to go to the next block. And then the process comes to a place where everything is bad, and then works with a speed of 1 MB/s or less.


OS — Ubuntu 10.10, the drive is connected via USB.

Then it is better dd_rhelp. He's using ddrescue, but can't shut up on bad-sectors.

Perhaps in this case will help using the tools ddrescue and dd_rescue. On the Internet a lot of information on these programs. If you look under your case.
