Hi Guys, I'm having trouble with my 1TB hfs+ formatted mybook studio external drive. Its about a year old, however its had a good bit of use and been carried around alot. It's fallen over twice about a month ago but never been dropped. I left it plugged in whilst I used windows, then I noticed it was making a clicking sound.. The drive spins up fine and can be seen in disk utility, however the drive does not mount.
After finding out about this wonderful tool I tried version 1.10 on a few 10MB chunks at various locations on the drive (50, 250, 500, 750 GB). These all read the entire segment as an error. Ddrescue then proceeded to splitting areas. After a very long time ddrescue exited with no data recovered. I understand this is because the disk is completely illegible and the failed read commands take approximately a second to execute from this thread: http://www.mail-archive.com/[email protected]/msg00369.html I also executed ddrescue over the entire disk, this also read the disk as one big error. I also found that there were certain parts of the disk where the drive would start clicking, sometimes this did not stop until I unplugged the data cable from the computer, other times not until I disconnected the power. An attempted clone with data rescue 3 did start reading some of the data off the disk, it just took very long (which I understand is typical). However when I tried a deep scan, it froze on block 0. My question is, as my drive suddenly stopped working when I plugged it into windows, and since the clicking sometimes does not stop until I disconnect the power, could my problem be solved by flashing the drive's firmware? Or alternatively, could I try re-formatting the drive then reading? A hfs format takes only seconds so I can't imagine that it's changing much on the drive... However I have read that the process of formatting also identifies and leaves out bad sectors from the partition. But does it reconfigure the drive parameters that exist at the start of the disk, like the read/write arm parameters? Also would it make reading the drive a lot quicker? Would it even be able to format the drive? I'm a bit puzzled by the behaviour of the drive, I get the idea that most of the time bad sectors appear in limited amounts, i.e. the whole drive won't just suddenly be completely filled with bad sectors like mine.. Unless the read/write head is broken, is that a possibility? I understand that my drive is most probably completely stuffed, however any suggestions would be appreciated! I'd like to get about 20GB of photos off the end of the drive, however its a loss I'm willing to bear. I'm quite enjoying playing round with it actually :P -- View this message in context: http://old.nabble.com/Reformat-then-recover--Flash-firmware--tp26449736p26449736.html Sent from the Gnu - ddrescue mailing list archive at Nabble.com. _______________________________________________ Bug-ddrescue mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-ddrescue
