Hi,
At the request of tivoupgrade, I'm posting this here.
I'm trying to rescue an HDVR2 drive with the beta CD of PTVupgrade, and I'm having some problems with dd_rescue.
I can't use the -B switch or the -A switch (unknown command error), and -b 2M gives a segmentation fault. Basically I am only able to use:
dd_rescue -v /dev/hda /dev/hdb.
I'm trying it with dd_rescue -v -b 2048 /dev/hda /dev/hdb, hopefully that will increase the speed a bit. (Is that the same as -b 2M?)

Anyway, fingers crossed that this will save the drive. Hopefully tomorrow afternoon sometime I'll be able to post results.

Thought I'd give an update. Even with the problems with the command options, the dd_rescue worked fine, with all recordings intact.

Now here's the freaky part: Afterward, the MFSinfo command resulted in this:

Primary volume header corrupt, trying backup.
Secondary volume header corrupt, giving up.
mfs_load_volume_header: bad checksum
segmentation fault.

So I was just assuming it wasn't going to boot at all again. But somehow it did! Something on my failing drive must have been really messed up.
