Dos access

[John B. Jr. Rogerson]

I have just installed System V/AT version 2.2L on an 8Mhz AT clone.
>From the limited time that I've had to test things, I've only run
accross the following problem.  Drive c: on my system is the DOS
partition on the hard disk.  If I type "dosdir C:", I get a directory
listing of the root directory of the DOS partition.  If I type
"dosdir C:subdir", where subdir is any subdirectory name, I receive
an error message saying "Bad FAT"  followed by some 4 digit number that
changes with the subdirectory name.  Similarly, if I type
"doscp C:filename filename", I receive the Bad FAT notice.  I would be
most grateful for instruction on what I am doing wrong.  Thank you.
