Drive letter manipulation
Microsoft Windows SP3 XP [Version 5.1.2600]
I need some suggestions on the reassignment of drive letters. Explanation: Assume for the moment that no reserve drive letters exist. I have a USB external drive that was partitioned as A - E. I have a USB external drive that is accessed as F. The A - E drive(s) are used in a backup rotation. Unfortu- nately, the backup requirements have begun to exhaust the available allocations of A - E. Additionally, F contains only user data. "Many" internal references exist specifically describing F, throughout the system. When I reformat/unpartition A -E, F will be dropped back to B. Obviously, this will negatively affect all the previous F references. So, I need a way to "direct" all the F references to the relocated B, so I don't have to manually change the F references to B. I have been reviewing DOS commands, specifically the "assign". But assign is removed from this system.in the favor of "subst". However, and empty subst command, while honored, produces no return information. And, the command explanation(s) seem to suggest restrictions involving my need. Assuming I located a "reroute" command, I could insert something like "reroute F to B" inside my autoexec file, and the new drive assignment would be permanently resolved at each system inirialization. Is something like: http://www.ehow.com/how_2131593_assi...usb-drive.html what I need? Or, maybe something like: https://groups.google.com/forum/?hl=en#!searchin/microsoft.public.windowsxp.general/drive$20letter/microsoft.public.windowsxp.general/PK1AWfNF4f4/bWAe60xvmW0J Unlike these similar postings, my USB drives are never detached/reattached. Confirmations/ideas? Thanks, Gary |

Confirmations/ideas? Thanks, Gary Remove the 'A-E' usb drive and insert the one you want to be F:, letting Windows temporarily assign it as drive B: or whatever it wants. Now right-click My Computer and select Manage, then Disk Management. Find your USB drive in the list. Right click it and select Change Drive Letter and Paths. Change the drive letter to F. Windows should now remember it and try to assign it as drive F: again next time you re-insert it. |

Stated another way, a "user-assigned F", overrides the random system assignment of F to the partition. So using that interface to change the letter from randomly assigned B to user assigned F, it gets to keep the F later. ******* If the drive with the newly assigned F is unplugged, then F again becomes available for random assignment. That can have consequences, if you have programs automatically writing to F, you unplug the thing with the user-assigned F, and then those programs attempt to do their thing. I have that problem here, with a RAMDisk I use, and when the RAMDisk isn't running, stuff writes to whatever happens to be F: at the time. (It's a pure coincidence, that my RAMDisk partition is F: also.) When I get a new computer, I typically use that interface to set my optical drive to "Q:", so it will be half-way between the two limits of drive letters. That way, my optical drive isn't "moving around on me" later. So user-assigning things, does have some advantages. When you multi-boot several Windows OSes, the drive lettering scheme is not kept between OSes. If you want a user-assigned partition to be F on all three OSes, then you'd need to make the assignment in each OS for it to stick. One OS doesn't know what the other OS is using for drive lettering, and couldn't completely honor the assignments in any case (C: is a special case of sorts - each OS has its own idea where the C: should be).

Drive letter manipulation
Hi Gary
Some time ago I had the same problem and found a solution in a program called "USB Drive Letter Manager" (USBDLM). It's not an easy to use program because first you have to identify every external USB hardware device but after that you have lot of options for how Windows uses en sees these devices. Here it's still working like a charm, even on Windows 7x64. Good luck, Tom On Sat, 9 Nov 2013 18:36:18 -0800 (PST), anonymous wrote: Microsoft Windows SP3 XP [Version 5.1.2600] I need some suggestions on the reassignment of drive letters.

I did visit the maintenance panels you mentioned. That is a far better approach for my need than my original idea(s). I need to review the drive letter maintenance facility a little further, but it seems like I might just be able to "lock" the F drive now, without the need of disconnecting the A-E partitioned unit. Then, once the A-E unit is reformatted/de-partitioned back to A, the locked F drive will remain in place. whatever.... one way or the other, your suggestion is certainly the appropriate answer. Thank you very much.

Paul Thanks Paul, I think I have a good idea of what needs done, and where to do it now. You've also provided valuable information on propagating the drive specification across multiple systems. Thank you very much for your assist. |

Generally, I'm a lot happier using an OS provided facility, than the introduction of new SF. However, your testimony to the value of this APP is greatly appreciated. And I also value your contribution. Thank you very much. |

I also believe you are correct in stating that my review into assign, subst, autoexec, etc, is entirely incorrect. Please see other suggestions regarding how this should be done correctly. Thank you very much for your interest and contribution. |

Confirmations/ideas? Thanks, Gary I just wanted to briefly relay my experiences with this drive reconfiguration issue. Referencing my earlier explanation, I de-partitioned A-E, and then formatted A as the full physical drive. This caused no movement/reassignment with the F drive, which was the point of my post. So, it appears that, unless manipulated via the "drive letter modification" panel(which I was directed earlier), no drive letter repositioning/reassignment will ever occur. IOW, my questions and concerns for initiating this post were entirely unfounded. I apologize for taking valuable time for this issue. Thanks, Gary |
