I am at work so I must be brief. I see you are using my very new utility ddru_ntfsbitmap. I hope it works well for you. What I do see in your commands is that after a failure, you leave out "-m /tmp/domain_logfile". Leaving that out will cause ddrescue to read the whole partition and not just the used part. So your command after a failure should be more like "ddrescue -A "-m /tmp/domain_logfile -v /dev/sdb1 /tmp/Image.img /tmp/Image.log", unless you do wish to recover the whole partition and not just the used part.

First of all thanks for your fast reply!

OK, I'll add the "-m /tmp/domain_logfile" in case of driver failure - glad I asked first :)

As for mounting, I personally would not try to mount it until the recovery is finished. And if it were me, if possible I would make a backup copy of the recovery before attempting any "fixing" or mounting, especially if there are errors.

Of course I would make a copy of the "unfinished" image and do all the experiments on the copy, but thanks for pointing that out.

But let's assume that the drive doesn't power up any more. How to recover from the "unfinished" .img file that we got left? Is this even possible?


Thanks for your answers and greetings from Slovenia,
