    Windows has confused my harddrives


    I'll do my best to explain my situation. I recently reinstalled windows 8 on a computer with 3 drives. 1 operating (drive A) on its own and 2 drives (Drive D) that were in a pool together. For some reason after the reinstallation windows decided that drive D was drive A. Now the drive is inaccessible and all recovery tools that try to search drive D seem to assume it is drive A. I know this because the quick search they pull has the folders that would have been on drive A. Drive A remains functional. Is there any way to recover this data? Nothing new has been written and I've yet to reformat the drives. I'm honestly not even sure WHY windows would be doing anything to the drives other than reading them. The pool drives are displaying the error "Error unrecognized configuration" in the storage spaces setting. Any help would be greatly appreciated.

    Drives A: and B: are reserved for floppy disks. Are you thinking of two separate HDDs ?

    I have been using A and B for backup drives A internal 3 TB and B eSATA 3 TB seems to be working ok for me.

    Applying the scheme discussed above on a fairly modern Windows based system typically results in the following drive letter assignments:

    • A: Floppy disk drives, 3.5" or 5.25", and possibly other types of disk drives, if present.
    • B: Reserved for a second floppy drive, if present.
    • C: First hard disk partition.
    • D: to Z: Other disk partitions get labeled here. The letter D: or E: are often assigned to CD-ROM, DVD drives but not always. In fact, Windows assigns the next free drive letter to the next drive it encounters while enumerating the disk drives on the system during installation. Drives can be partitioned, thereby creating more drive letters. This applies to MS-DOS, as well as all Windows operating systems. Windows offers other ways to change the drive letters, either through the Disk Manager (Windows NT, 2000, XP and later) or through the Device Manager found in the Control Panel. MS-DOS typically uses parameters on the line loading device drivers inside the CONFIG.SYS file.
    • F: First network drive if using Novell NetWare.
    • H: "Home" directory on a network server.
    • L: Dynamically assigned load drive under Concurrent DOS, Multiuser DOS, System Manager and REAL/32.[6][7]
    • M: Drive letter for optionally memory drive MDISK under Concurrent DOS.[6]
    • N:, O:, P: Assignable floating drives under CP/M-86 4.x, Personal CP/M-86 2.x, DOS Plus 1.2-2.1 (via BDOS call 0Fh), a concept later extended to any unused drive letters under Concurrent DOS, Multiuser DOS, System Manager, REAL/32 and DR DOS up to 6.0.[6][7]
    • Q: Microsoft Office Click-to-Run virtualization.
    • Z: First network drive if using Banyan VINES, and the initial drive letter assignment for the virtual disk network in the DOSBox x86 emulator. It is also the first letter selected by Windows for network resources, as it automatically selects from Z: downwards.

    Drive C: usually contains all of the Windows operating system files required for operation of the computer. On many modern personal computers, only one hard drive with one partition is present, so it is designated C:. On such a computer, all of a user's personal files are often stored in directories on this drive as well. These drives can, however, be different.

    Reading this I could have an issue using B as a back up drive? I got this from http://en.wikipedia.org/wiki/Drive_letter_assignment Although I have not experienced any. That could be since theoretical I'm using it as a floppy replacement a back up drive?

    You can use those drive letters if you want, but I think what CountMike is saying is Windows won't assign them to hard drives on its own.

    The drive currently marked drive Z (Disk 3) is the stand alone drive that is working properly. Disk 1 and 2 are the pooled drive that windows seems to think is drive Z. I have also included a screenshot of the contents of drive Z, and a recurva scan of the Disk 1. None of the folders appearing in the scan should not be there as they did not exist before the reinstallation.Click image for larger versionClick image for larger versionClick image for larger version

    I'm sorry if my original explanation wasn't clear. The drive letters themselves are not the issue. Windows is looking at the pooled drive and expecting it to be drive Z (Disk 3). I have no idea why it's made this decision and as far as I can tell that's what has made the drives inaccessible. I did have an additional harddrive installed when I did the fresh install of windows, but was forced to remove it when windows would not boot. The drive itself is working (tested with a usb drive mount), but that's an another issue altogether.

    No problem as far as I'm concerned. Actually the OP confused things by calling the drive, drive A when that was not its actual drive letter.

    I think what you have to do is resetup your storage pool. Then just reassign the drive letters to what you want them to be.
