I recently replaced the HDD in my laptop, and re-installed Windows & Ubuntu. Now I want to restore the various virtual machines I had set up on the old HDD, which is mounted in an external USB enclosure. I can read the HDD okay, and the 'bad' spots seemed to be in the Windows partition... but whenever I try to restore the VDI files the copy errors out. I've tried drag-n-drop in Nautilus, I've tried grsync, etc. Always bombs out on the VDI files. I've copied over multi-GB dvd iso images with no problem, but the VDI files always fail the checksums.

Any ideas?

You might want to try a file recovery software like photorec. As it seems that you are working with a damaged drive.

Another idea, did you try opening the vdi file directly from the old hdd? I am not sure how that would help to be honest, but if that drive mounts and delivers data, you could check if the vdi file is corrupted, or whether this is a balky broken hdd that is just unwilling to give up the data.

Indeed, even if the file is quite corrupt, I would think you should be able to copy it anyway, even if you couldn't actually use it.

I am not expert, just trying to help :-)

Good luck.

Eventually I just went ahead and tried starting the VMs in Virtualbox. Some worked, some gave an error, but worked fine once I discarded the current state and did the equivalent of a hard reboot (i.e. poweroff and restart). Apparently what was getting corrupted was the file(s) that keep track of the 'state' of the VM... nothing too critical. – memilanuk Nov 4 '11 at 20:56
yeah all you need is the vdi file and you are ready to go, although you will need to reinstall guest additions perhaps. the other files are not critical – RhZ Nov 10 '11 at 13:37
