Hi Joe,
There is no dd limit that I am aware of. I have used dd to successfully clone
160 GB disks in the past. You may be running into bad sectors on those 30 GB
disks.
That was my first theory, but it happened at the same place
on two independant disks (same model). These disks passed
chkdsk (not a stringent test admittedly).
I'm now trying a different sized disk on a different machine
to see where the problem is
Try the following command:
dd if=<source_disk> of=<image_file> conv=noerror,sync
The "noerror" and "sync" options tell dd to continue after read errors, e.g.
bad sectors, and pad the output to match the input block size.
OK. At the error spot I've filled the disk with zeroes
so this should give a reasonable img if there's a problem at
this spot.
Thanks Joe
