SUMMARY
=======
If you use the MS-DOS FORMAT command to reformat a fixed disk drive and you
terminate the command by pressing CTRL+C (or CTRL+BREAK) at the "Proceed with
Format (Y/N)?" prompt, later attempts to access the drive produce the following
error, even if the drive was properly formatted before the abnormal
termination:
Invalid media type reading drive X
Abort, Retry, Fail?
WORKAROUND
==========
To regain access to the drive, do the following:
1. Issue the FORMAT command again, and press N (for No) at the "Proceed with
format (Y/N)?" prompt.
2. Reboot the machine.
STATUS
======
Microsoft has confirmed this to be a problem in MS-DOS versions 5.0, 5.0a, and
6.0. This problem was corrected in later versions of MS-DOS.
MORE INFORMATION
================
This condition is caused by an error in the MS-DOS FORMAT CTRL+C handler. When
FORMAT is terminated at any point by pressing CTRL+C (or CTRL+BREAK), it assumes
that the disk is only partially formatted and therefore unusable; therefore, the
disk is marked as such.
