How to fix the problem that the drive letter cannot be displayed? 20

Phenomenon: The ** of hard disk is getting cheaper and cheaper, so many friends have begun to consider adding a large-capacity hard disk to form a dual hard disk system. However, after installing the second hard disk, the drive letter on the old hard disk and the new hard disk will cross the disk letter, that is to say, the C drive is still the partition where the operating system is installed in the old hard disk, while the D drive has become the partition of the new hard disk, and the D drive in the old hard disk has become the E drive, so that there will be a lot of trouble when calling the file, and even cause some programs to be unusable.

1)windows 20000／xp

Windows 2000 XP generally does not produce the problem of drive letter crossing, but the premise is that only one hard disk is installed when installing Windows 2000 and XP, and the second hard disk can be hung after the installation is completed, if Windows 2000 XP is installed after adding the second hard disk, then there will still be drive letter crossing, and this is permanent, even if the second hard disk is removed, it will not help. However, we can go to the "Control Panel Management Tools Computer Management" window, select "Disk Management" under "Computer Management", select the corresponding partition, execute the "Change Drive Name and Path" command from the right-click menu, click the "Change" button in the Figure 1 dialog box, and then reassign a drive letter, and then repeat the command for other partitions.

2)windows 9x/me

There's an easy way to fix this, just use a little bit of brains in the BIOS setup program and set the first hard drive"user" or"auto" and set the second hard drive to"none'This way, although the BIOS cannot discover the drive, the plug-and-play feature of Windows 9X ME will automatically detect the second drive and automatically assign a drive letter, so the worrying drive letter crossing phenomenon is no longer there. Of course, in pure DOS mode, the second hard drive is not visible.

3)fdisk：

When executing the fdisk command partition, we can check the "change current fixed disk drive" item, then select the second hard disk to delete all partitions, and then select "create extended dos partition" to allocate all the space to the extended partition, and then partition again. That is to say, instead of creating the primary partition, only the extended partition is created, and finally formatted is enough.

Right-click "My Computer" - "Management" - "Disk Management", find those partitions without disk symbols, right-click - "Change Drive Letter or Path" - "Change", and specify a drive letter -OK
