    Strange new drive appeared after upgrade to Windows 8

    I have recently upgraded from 7 Ultimate to 8 Pro. In backup and defrag I see this drive \\?\Volume{95......}

    I can not see it in Windows explorer even if I show hidden files but if I type in the address in the run window it takes me to the root of the C drive which (it seems) is empty.

    Does anyone know what it is and if it is a problem? I only have C drive connected

    Edit: I deleted this value from HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices but after reboot another drive was added:


    I have reverted back the registry backup I made so deleting from registry does not help. The install was a clean install after formatting the drive, not an upgrade.

    I'd appreciate it if anyone has any idea.

    Most PC's have a "System Reserved" or "Recovery" drive.

    On mine it is D:\

    with C:\ being Local Disk...

    Maybe it's a code name for one of those?

    Good luck!

    Aren't restore points named something like that?

    I haven't seen anything like that on my Win8 PC. Did you delete all partitions on the hard drive before you installed it?

    I did a clean install after upgrading from 7. I formatted C and the Lenovo recovery drive which was a hidden drive with letter Q during this process. After the upgrade I merged the 2 as Win 8 doesn't want a recovery drive as far as I know. Now I only have C drive except for these 2 situations - system restore and defrag. It is a bit odd - the drive letters look a bit like some sort of software installed package but as yet I've not installed anything except Office and TN5250.

    I also deleted all restore points (turned off and on protection in system properties) and then recreated a new one but it made no difference.

    Welcome to EightForums, adamf.

    The Leveno or OEM participation is a different type of partition than a Windows system partition. You were able to see the OEM partition in disk management?

    I didn't reformat the system partition (I don't think you can actually). I reformatted C drive and Q (Lenovo win 7 recovery partition) as par of the upgrade process. After 8 was installed I had C and D and then I deleted D and merged it into C as D was the old Q.

    Does that make sense?

    Win 8.1

    Hello Adam,
    Any fix to your problem?
    I got the same new volume after upgrading to Win 8.1 from Win 8.
    It starts with \\?\Volume{ ... and it is heavily fragmented but Disk Optimization cannot fix it.
    I would appreciate any hint.
