FDISK is nothing more than invoking INT13 hard disk services directly, whereas the other activities use the built-in MSDOS driver for C:.
Some old BIOSes had a BIOS "antivirus" provision. Make sure that if you've got it, that it's disabled.
Try running the attached partition display program from a DOS floppy. See if it hangs also.
Thank you Chuck, I will try this later today. I have disabled the anti-virus option in the BIOS and have looked for anything else which may try to block the update of the master boot record, but so far nothing stands out.
I did try a FDISK /MBR on the WD 4.3 GB drive. This command did not hang the system, but a subsequent FDISK did hang so it appears the /MBR option had no effect - if it even did anything.
Thanks...Joe
