SYMPTOMS
You may encounter the following problems with Windows NT if you have an optical drive:
- Mismatched drive letters. For example, the letters Setup displays during the text mode portion of Setup do not match the drive letters the system assigns to the drive when Windows NT is running.
- Phantom free spaces or partitions on the optical drive during the partitioning portion of Setup.
- Incorrect reporting of partitions on the optical drive. (These are usually off by a factor of 2.)
- Problems formatting optical media, coping files to optical media, and so forth.
CAUSE
These symptoms usually occur when the optical media in the drive is using 1024-byte sectors instead of the 512-byte sectors (as expected). In this case, you should ignore partitions on the optical media and avoid selecting, creating, or deleting them (these operations may not be harmful in some cases, however this has not been fully tested).
RESOLUTION
Ensure that your hard-disk-type removable media drives contain media before you run Windows NT Setup. Setup treats hard-disk-type removable media drives as ordinary hard disks; that is, an input/output (I/O) error resulting from no media in the drive appears similar to a general I/O error from a hard disk. These errors are usually considered fatal by Windows NT Setup, which prompts the message:
