Have you ever installed a dual hard drive? I believe many people have experience in this regard - the most common problem after installing a dual hard drive is "drive letter confusion", that is, after installing the second hard drive, you will find that the drive letter of drive D in the first hard drive has changed. For example, your original first hard drive has partitions C and D on IDE1, and the newly bought second hard drive has partitions C and D on IDE2. After installing the dual hard drive and correctly setting the parameters of the two hard drives in CMOS, when you check "My Computer", you will find that all the contents originally in the old hard drive D partition are now in drive E, and drive D has become the first partition of the second hard drive. The specific distribution of each partition is as follows: drive C (old hard drive), drive D (new hard drive), drive E (old hard drive), drive F (new hard drive). Such a change in drive letters makes almost all the software originally installed in the old hard drive D partition unable to be used.

Maybe this headache problem has troubled us until now, but we can't re-partition and format all hard drives and start from scratch again! Actually, this is all because Windows can't let you specify the drive letter (the ASSIGN command is available in DOS, and the drive letter can also be replaced, but it's not so practical for Windows users).

Letter Assigner can let you specify the disk drive letter in DOS or WINDOWS! It provides a program in MS-DOS, so that you won't not find your hard drive in DOS. Letter Assigner identifies the disk by recording the physical serial number of the hard drive or the volume label (label). You don't need to worry that the drive letter will change due to re-partitioning of the hard drive or adding new hardware, and the program will not remember the original arrangement.

It should be noted that: Letter Assigner does not allow you to change the drive letter of the hard drive where Windows itself is installed (for example, if Windows is installed on drive C, then the drive letter of drive C under Windows cannot be changed). In addition, there are restrictions on compressed disks, but you don't need to worry because when you make inappropriate adjustments, the program will display a warning message to tell you that the program cannot perform the action you requested.

In DOS, you can use Letassig.exe to specify the drive letter. The format is:
LETASSIG X=mylabel or X=（nnnn-nnnn）or X=Y:，
The meaning is: /M displays detailed mapped disk volume label information;
/O:file outputs the drive letter list to a specified file;
/CD virtually makes the current directory a hard drive letter;
/nologo does not display the program name, version and copyright information when running Letassing.exe;
X=mylabel specifies the new drive letter of the disk with volume label (label) Mylabel as X;
X=（nnnn-nnnn）specifies the new drive letter of the disk with serial number (serial number) nnnn-nnnn as X;
X=Y: specifies the new drive letter of the disk with current drive letter Y as X.

For example: Assign drive letter D to the disk with volume label "hjz898", assign drive letter E to the disk with serial number 56A9-7F3D, assign drive letter F to the disk C: which has been assigned a drive letter by the system, and display detailed mapped disk volume label information, then execute letassig/M D=hjz989 E= (56A9-7F3D) F=C:即可.

If you use a memory emulated hard drive (virtual hard drive), Letter Assigner can also let you specify the drive letter of the virtual disk by identifying the "MS-RAMDRIVE" disk volume label.

Oh, I just forgot to provide the download address,

Here are the download addresses for Letter Assigner:

Installer (for Windows): Open attachment Link invalid (admin note)

DOS program: Open attachment Link invalid (admin note)

Good software.

Yes!

Try using it.

It's useful only if you can swap drive letters.

Although the address is invalid, I also thank the LZ for his dedication. Reward 40 points.
