When a CD-ROM drive is initialized under Windows NT, it uses the firstavailable drive letter. There is no straightforward method of choosinga drive letter. However, you can set up your other drives andpartitions in Disk Administrator such that the drive letter you wantto use for your CD-ROM is unused. For example, if you have twopartitions and you want your CD-ROM to be drive D, use DiskAdministrator to set the partition drive letters to C and E. When theCD-ROM initializes, it will use D because it is the first availabledrive letter.

NOTE: This workaround does not let you choose a drive letter that isused for a network drive. The next available drive letter used by alocal physical drive will be used by the CD-ROM. There is noworkaround.

NOTE: You can also use the SUBST command to assign a different driveletter to the CD-ROM drive.

Microsoft has confirmed this to be a problem in Windows NT version3.1. We are researching this problem and will post new informationhere in the Microsoft Knowledge Base as it becomes available.
