 『楼 主』:
很有用的磁盘盘符修改工具
使用 LLM 解释/回答一下
大家有没有装过双硬盘呢？相信很多人都有这方面的经验——当在安装完双硬盘后最常发生的问题就是“盘符错乱”，就是在安装了第二块硬盘后，你会发现第一块硬盘中D盘的盘符变了。如你原来的第一块硬盘分C、D两个区在IDE1，而新买的第二硬盘分为C、D二个区在IDE2。在安装了双硬盘并且在CMOS中正确设置了两块硬盘参数后，查看“我的电脑”，会发现原来在老硬盘D区的所有内容现在全都跑到E区去了，而D区变成了第二块硬盘的第一个区，各个分区的具体分布如下：C区（老硬盘）、D区（新硬盘）、E区（老硬盘）、F区（新硬盘）。这样盘符的变更就使得原来安装在老硬盘D区上的所有软件几乎都没法使用了。
可能这个个头疼的问题困扰我们直到现在，但我们总不能再将所有硬盘重分区和格式化一遍，然后再从零开始安装吧？其实这全是因为Windows没有办法让你指定盘符而造成的（DOS中有ASSIGN命令，也可替换盘符，但对WINDOWS的用户就没有那么实用了）。
Letter Assigner能让你在DOS或WINDOWS中指定磁盘盘符！它提供了MS-DOS中的程序，让你不会在DOS中找不到自己的硬盘。Letter Assigner以记录硬盘的实体序号或是卷标（label）来辨别磁盘，你不用担心因为硬盘重新分区，或是增加新硬件而导致的盘符改变，会让程序不记得原来的排列。
值得注意的是：Letter Assigner不允许你将Windows本身所安装的硬盘改变盘符（如Windows安装在C盘，那么在Windows下C盘盘符是不能更改的），另外压缩磁盘也有所限制，不过你无需担心，因为当你做了不适当的调整时，程序会出现警告讯息，告诉你程序无法执行你所要求的动作。
在DOS下你可以使用Letassig.exe来指定盘符。其格式是：
LETASSIG X=mylabel或X=（nnnn-nnnn）或X=Y:，
其意义是：/M显示详细的映射磁盘卷标信息；
/O:file将盘符列表输出到一个指定的文件；
/CD将当前的目录虚拟成一个硬盘盘符；
/nologo在运行Letassing.exe时不显示程序名、版本和版权信息；
X=mylabel即将磁盘卷标(label)为Mylabel的盘指定其新盘符为X；
X=（nnnn-nnnn）即将磁盘的序列号（serial number）为nnnn-nnnn的盘指定其新盘符为X；
X=Y:即将现在盘符为Y的磁盘指定其新盘符为X。
例如：将盘符D分配给卷标是“hjz898”的磁盘，将盘符E分配给序列号为56A9-7F3D的磁盘，将盘符F分配给系统已分配好盘符的磁盘C：，并且显示详细的映射磁盘卷标信息，则执行letassig/M D=hjz989 E= (56A9-7F3D) F=C:即可。
若你以内存仿真硬盘（虚拟硬盘）的话，Letter Assigner也可以用辨识“MS-RAMDRIVE”磁盘卷标的方式让你指定虚拟磁盘的盘符哦。
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.
