    I had a drive and the partition disappeared and now shows up as untitled or sometimes the drive comes up as unformatted and osx requests to format. I am running partition recovery. How long will this take on a 750Gb drive? It doesn’t look like it is doing anything at all….It says “searching for lost partitions please wait”. But it’s been stuck there for like an hour with no update.. Is it crashed? If the partition got messed up somehow, is there any chance of data recovery? It got damaged by a bad drive dock (Thermaltake BlackX Duet). Thanks.

    Cancel partition scan, and try Deep Scan, is it proceeding better? If you are still experiencing the same issue, we’ll need some logs from you: /help/troubleshooting-basics/

    Was there any followup on this. The same thing just happened to me, or something quite similar, which is that I had two 2TB HDDs in a Duet (the older one, with the eSata, but using USB on my Macbook Pro), and suddenly it seems, one of the HDDs had started identifying itself as the other, with the same root directory, but gibberish in the subdirectives. At first, I though it was just a disk repair problem, and used the Mac Disk Utility, but that seems to have confirmed, maybe aggravated, the problem. Now, running quick scan, I found less than 10 gigs of files, of the the 1.6 TB that was on the disk. Searching for missing partitions, I found another virtual of the same size (listed as 1.8TB size, as was the first). Scanning that showed only a few megs. I haven’t tried the Deep Scan yet, but am now seriously worried that in one instant the Thermaltake (and my subsequent attempts to recover?) may have led to losing 1.6TB of data, most of which I have elsewhere, but it will take me dozens of hours to reduplicate what I can from existing sources. Today’s event was at the end of an attempt to get everything from many sources in a single duplicable disk, but unless I can somehow recover the directory which is what I presume the Thermaltake Duet replaced, a lot of work will have been wasted. Of course, I should have kept an exact duplicate of the HDD as I went along, but I didn’t. The HDD was formatted in FAT32 to make it compatible with Windows machines, so it may be recoverable by Windows if it isn’t via the Mac. Any recommendations what to do before I make anything worse?

    I probably should add that I’ve read a dozen of so google entries by people who’ve lost partitions one way or another on the Duet device. Speculation seems to be that it’s the hardware chip in the device.

    Having observed the deep scan running on the virtual partition, I see that it’s likely to be able to identify all the files as potentially recoverable – but so far they’re only identified by file type. I.e., no information as to title, folder structure. If I end up with 200k files or so, identified only by type, the recovery can hardly be worth it. It suggests it’ll take another 24 hours to complete the scan. Will it sometime add any more info about each file, such as file name, e.g.? If not, it’s probably not useful unless I can somehow identify particular files I need, but even that seems unlikely, because without any hint of folder structure, I’m unlikely to know what I can’t get more easily somewhere else. Any thoughts you have would be appreciated.

    Unfortunately no. It’s Deep Scan, it reconstructs the files from pieces, and their properties are stored in the directory, which you obviously lost. Seems like it’s the only option for now, and I agree that it will be a huge problem to rename and recover the files you need this way, but it’s not much that can be done about it.

    Emailing us with reference to this topic will also be useful in terms of getting potentially more help than we can provide via forums, as we may still get more details from you.

    Thank you for looking into this. And I do think that your case is different from the original one specified in this topic.
