Trying to recover files from "Deep Scan"
Posted: 11 Jul 2012, 19:33
This started off as what I thought was a bug report, but now it's a feature request.
I've had a Xen server lose one of its VMs' disks, I'm doing a deep scan on the parent machine's LVM volume. There's been an unsuccessful attempt at recovering the meta data earlier, so I'm at the point where I'm just trying to locate the ext3 filesystem and extract the /var/lib/mysql directory from the machine.
The frustrating thing for me is not the fact that it takes my machine four or so hours to perform, but that it's SO EASY to accidentally hit "enter" on the partition list instead of "p" - and then you're stuck, you can't go back up to the partition list. Your only choice from that point forward is "quit" back to the main menu, losing ALL of your deep scan results and having to REPEAT the deep scan just to try to look at the next filesystem. I've lost days worth of working time just from having to wait for deep scan to complete (AGAIN) over this really, really horrible UI issue.
I'd be happiest if exiting the deep scan required a "Are you SURE?" confirmation. Heck, maybe only require it if the deep scan took more than a minute. But you shouldn't be able to lose four hours worth of deep scan just because you select a partition by pressing "enter" instead of "p".
One other option that'd be awesome would be if there were an option for deep scan to do just a little bit more checking on the filesystems it's listing. For most of the results Testdisk finds, when I hit 'p' on a partition it says "it's damaged" instead of giving me a file list. I would LOVE to have the option to hide all partitions in which no files are detected.
Anyway, if there's some option somewhere which I've been overlooking that would make it behave as I'd expect it to, please point me to it and I'll shut up. Thanks in advance for anything you can tell me!
