    Changing Drive LTR, Remapping Programs (XPP)

    Say you have a series of three drives C, D, and E.

    You use Partition Magic to merge C+D -- what's left automagically is Drive C and Drive E.

    So far so good. No impact on registered/installed programs on Drive E. Drive D has just been removed from the chain of assigned Windows Drives.

    Now I want to turn E into D.

    Question: is there a utility that will "move" all the installed programs (as far as the registry is concerned) when I remap Drive E into Drive D?

    That is, I don't want to actually move the programs from E to D (I have a utility that can do that). I'm looking for a utility that will remap the registry/shortcuts/log files to a new drive designation when the drive designation is changed (with XP's Drive Manager or Partition Magic).

    Thanks.

    Re: Changing Drive LTR, Remapping Programs (XPP)

    In windows 2k and XP, you can do this using the Computer Management.

    To open Computer Management, click Start, point to Settings, and then click Control Panel. Click Performance and Maintenance, click Administrative Tools, and then double-click Computer Management.
    You must be logged on as an administrator or a member of the Administrators group in order to complete this procedure. If your computer is connected to a network, network policy settings may also prevent you from completing this procedure.
    A computer can use up to 26 drive letters. Drive letters A and B are reserved for floppy disk drives, but you can assign these letters to removable drives if the computer does not have a floppy disk drive. Hard disk drives in the computer receive letters C through Z, while mapped network drives are assigned drive letters in reverse order (Z through [img]/forums/images/smilies/cool.gif[/img].

    Isn't that exactly what the DriveMapper utility included in Partition Magic does? It used to be a sorta separate app, now whenever you merge partitions, upon reboot you're asked whether you'd like DriveMapper to detect any changes that need to be made to program references, etc. I wasn't aware that the built-in Computer Management applet had this capability - I would stick with PM.

    This will remap the drive from E to D. But it won't make changes in the registry so that what used to be a call to E:Program FilesAProgram.exe is now D:Program FilesAProgram.exe. Or will it?

    I'm using PM Pro 7.0.

    I didn't see this described in the help file/manual. But I'll look again.

    The only procedure I've done so far is to merge C with an empty partition (so upon reboot it didn't ask me anything).

    ....
    Oops. Found a reference to DriveMapper in the PDF file: seems it won't work with my system:
    <blockquote><hr>
    DriveMapper will run automatically if the following conditions are all met:

    Strange, since I could have sworn it's run itself automatically for me in a WinXP environment and with some NTFS drives. Anyway, you can still run Drive Mapper manually once you've done the merge - it's in the Partition Magic 7.0 folder in your Programs menu.

    We need a head slap emoticon.

    I think when I installed PM 7 I opted not to install DriveMapper, so it's disabled on the Tools Menu.

    I just discovered another mystery... Perhaps you can shed light.

    I have three physical drives -- two scsi and one firewire. My boot partition is on the first SCSI. Previously (I'm pretty sure under 2k), DRIVE 1 was always this C/D/E/F drive, Drive 2 was a single partition (G), and the Firewire (added last after two CDroms and a Zip) was assigned K, and listed as Drive 3.

    Today, the firewire is listed as Drive 1!, the boot drive as 2, and the G partition as 3... I think drive assignments remain a mystery to me.

    Re: Changing Drive LTR, Remapping Programs (XPP)

    How about this one? <img src=/S/stupidme.gif border=0 alt=stupidme width=30 height=30> A tad too gory for my liking, when a simple hand smacking the forehead would suffice. Anyway, are you reading the drive letter assignments from PM or the Computer Management console? Should you not have a HD0 and HD1 for the SCSI, and then the fireware as removeable media?

    Re: Changing Drive LTR, Remapping Programs (XPP)

    Too weird.

    This is in Computer Management

    D0 = Firewire/DriveK
    D1 = Zip Removeable
    D2 = First SCSI / Boot Drive C/D/F
    D3 = Second SCSI Drive G

    This is in PM7
    D1 = firewire
    D2 = boot scsi
    d3 = Drive G

    The firewire isn't seen as a removeable drive. Wonder what'll happen if I unplug it, reboot, plug it back in?

    Is it causing you any problems? I mean, at least the driver letters are correct so that any universal files references aren't getting messed up.

    Re: Changing Drive LTR, Remapping Programs (XPP)

    Interesting discovery -- don't know if it will help anyone else.

    If the FireWire hard drive is plugged in and attached then both Partition Manager and Computer Manager/Drive Manager see it as the first physical drive.

    In addition, Partition Manager will NOT see an "active partition" -- since the active partion must be on the first drive. Any task in PM will prompt you that there is no active partiion. I continued anyway. Merging and resizing partitions worked fine anyway.

    However, changing drive letters with PM resulted in error 625 during boot -- basically: "Your drive configuration is different during boot than it is under Windows" -- I suppose because during boot it doesn't see the firewire at all.

    I disabled firewire, rebooted -- and not both PM and CM saw the boot drive as Drive 1 and that it had an active partition.

    I ended up reassigning drive letters in CM -- and then using DriveMapper to check references and so far it looks fine.

    (there isn't any advantage to changing drive letters in PM rather than CM, is there?)

    thanks for the help.
