    Windows 7 Pro 32 bit and d: drive

    Hello All

    I have just bought a laptop (Lenovo T400) with Win 7 Pro 32 bit installed. This has two partitions on the 160G harddisk - recovery (F:, 20G) and Windows_7 (C:, the rest). The DVD is D:\, and I guess that windows was installed from there. For my convenience, I want to move the DVD to probably H:, and split the windows drive into two.
    I have used diskmanagement to shrink C:, create a new partition (simple) move the dvd letter, and assign my new partition to D:.
    Manager says it is all OK, but explorer does not show the partition. If I call it something else (E: for example) it all works fine. This isn't really a problem, but I am curious.
    Why cannot I not presently use D:, and how do I fix this?
    Thanks in advance for any help,
    Mike

    Can you set the new partition as a logical drive? In my setup, I have 3 partitions and my DVD drive was automatically set to F. C is Win 8 RP, D is Win 7 and E is Data Drive. I did not have to change any drive letter. The system automatically set the DVD drive to the next available letter. The system automatically sets the active OS drive to C. So in my case when I boot to Win 7 that is C. This does not affect the drive letter of the DVD drive.

    You shouldn't have any problem doing what you are trying.

    In Disk Manager you change the DVD drive letter to H:.
    You shrink the C: drive.
    You allocate the remaining disk space on the drive to a primary partition, and format it, assigning the drive letter as D:

    All should be well, probably even better after a reboot.

    Windows Explorer is the reason I bought xplorer2 Pro...

    Hi Ted and BATcher
    I can create a logical drive, or a primary partition, and everything works as long as I don't want to call it D:
    It will mount on an NTFS directory.
    It seems to be a problem with the drive letter having previously been allocated to the CD/DVD.
    I have rebooted, with and without the DVD, still the same results.
    I have uploaded a snip of the management window with the partition (primary) mounted on an NTFS directory, but nothing changes here.
    If I mount it to D:\ it does not appear in my computer, or be available in a command window etc.
    Thanks

    In your screen shot the DVD Drive shows as E.

    I would try to assign a drive letter to the data drive. (most likely D should work). Do not worry about assigning a letter to the DVD drive. That should take care of itself.

    Hi Ted,

    I've tried so many options ...
    Here is the view with the new partition as D:, and the dvd drive with no letter.
    My computer still doesn't show D:\. (it has just had (another) reboot).
    Its not a great deal, but I am still curious.

    Uncheck 'Hide empty drives in the Computer folder' in Control panel > Folder options > View?

    Thanks satrow, hadn't thought of that, but it has made no difference!.

    I have also put it on E, created a directory and put a few files in, and put it back to D:, still doesn't show up.

    Thanks again

    Mike,

    Does you computer have an SD card reader? These are usually assigned drive letters but if there isn't anything in them they don't show up in the top list in computer management but will show up in the bottom section if your scroll the list. I did notice that your screen shot doesn't appear to show a scroll bar in the bottom section however. FYI.

    Mike, your problem is strange. My setup just automatically assigns all other devices to the next available drive letter (SC Card, DVD, Ext HD, etc.)

    When I first partitioned my HD for a dual boot, I assigned the new partition as W I think, then the OS took over and assigned all drives correctly.

    This is what mine looks like with 3 peripheral devices installed:

    DiskManager.jpg

    The drive letters were assigned in the order the devices were plugged in. As you can see the DVD drive remained at F Drive. This letter was assigned after all the internal partitions were assigned by the active OS.

    In my screen shot Win 8 RP is the active OS so has drive C. It was installed by resizing my original C Drive (Win 7) and installing to that unallocated space, hence it's physical location behind Win 7 and in front of my Data Drive.

    Hi RetiredGeek and Ted

    I don't have an SD card reader on this T400 (got two card slots instead).

    I have tried all sorts of things to get D: to have my partition! But I guess something is 'reserving' a letter for the DVD, even though I have moved it!

    Microsoft has some answers here:

    I noticed you have tried some of them already but there are a couple of other possible answers given.

    The plot thickens

    Hello all, and thanks for all your help.

    Jerry, I have been through the list on knowledge base, and tried everything on the list. Status is still no disk on drive D:

    However, I was working on this at work yesterday, connected to that network. When I got back home, I couldn't connect anything to drive D - it wasn't in the drop down list of letters, either for a disk partition or the DVD drive.

    Back at the office this a.m. D is back, large as life (twice as ugly), and still not showing up when my partition is mounted there. The partition shows up fine on other letters (B,E,...). Interestingly the DVD will no longer mount at D: - where it was earlier.

    I think it may be time to go back to an earlier system image, but I still curious!

    All the bet

    Mike

    Something seems to have definitely gotten fudged during the partitioning attempt. If you have an Image just before starting this whole process, it might be worth starting over. Like I said, my system does all this automatically with NO input from me.
