Before that, many drives Hmm, make it hits a sector that is going bad but can still be read after ECC correction. Come to think of it, Most drives will probably realocate the sector during regular reads if it requires retries and too much ECC correction. Good drives will give you bad sector errors no matter what if they cannot manage to recover the 100% correct information to remap the sector somewhere else. -- "One disk to rule them all, One disk to find them.

It was probably older than a year. I had bought it because my Hitachi/IBM had failed before too. Alvin is probably right - they (the hd manufacturers) use in 90% of the cases the same technology and machines so there should be only a small difference between the different drives. Anyway, I bought a Samsung 200Gb because it was the cheapest one and because the others available were IBM and Maxtor so let's see whether Samsung is better. Meanwhile, dd_rescue is almost done raw-reading the failed one after almost 24hrs. Thanks, Boris. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

The usual procedure is to copy the entire content of the disk into a file on another disk and then work with that - i.e. try to find partitions and files. You can use dd for copying but dd will have trouble with unreadable sectors. You can tell dd to skip a certain number of block but that will only solve the problem, if the rest of the disk is readable. I have heard that people have succeded using dd_rescue.

recover data from a hd
Hi there, my hd died this morning and I know it is too late and I don't have a backup but is there a way to do a raw read and gather all the information that can be read? One thing might be kind of a problem, however, since the hd is damaged at its very beginning and attempting to mount it gives I/O error on sector 0 and the consecutive ones. So, is there a way to jump after those erroneous sectors and read what's left. Any pointers would be greatly appreciated, thanks! P.S. I'm off to buy a new hd. Any particular brands I should keep away from? Regards, Boris. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
