sorry for posting here but possibly someone here will know the answer.
i have 120GB seagate in my thinkpad. yesterday i (possibly) overheated
the disk somehow, by putting laptop on flat sticky surface.
bad blocks developed on one partition like this
ad0: FAILURE - READ_DMA status=51READY,DSC,ERROR
error=40UNCORRECTABLE LBA=52944196
ad0: FAILURE - READ_DMA status=51READY,DSC,ERROR
error=40UNCORRECTABLE LBA=52955844
ad0: FAILURE - READ_DMA status=51READY,DSC,ERROR
error=10NID_NOT_FOUND LBA=52956740
i was able then (with normal cooling) to back up data from there, and tried
dd if=/dev/zero of=/dev/partition bs=1m
to force bad block reallocation.
but it doesn't work, then reading always shows read errors.
how to force this, or possibly is there any disk utility that would do this.
if it requires disk to be cleaned out (reformatted somehow) that's not
a problem
If you can, try the manufacturer's diagnostics
http://www.seagate.com/www/en-us/support/downloads/seatools/
If not, try plugging the disk in on a working system and use SMART
capabilities to check things out.
Most likely, you need a new disk, but depending on the relative value
of your time and the price of a disk, it's worth checking to make sure
before springing for new gear.
Good luck.
