@ larryf215:

"I BELIEVE WE PARKED THE HARD DRIVE YEARS AGO"

Parking was designed to allow the read/write heads of MFM/RLL drives to move out of the way of the platters (to prevent crashing into them); especially designed for when you relocated the machine.

@edward vs

If the hard drive isn't working, it may have the heads stuck in the park position. MFM's don't like being stored-away for a long period of time, but you may get some info from this thread:

Hi Larry,

expanding on T-R-A's comments, PARK was a small dos program which was run immediately before powering off. There were various versions of this with similar names, which were supplied by the pc makers, not Microsoft. After powering on, the hdd would run normally. I believe in more modern hdd's head parking is inbuilt.

Hi Edward,

if the IBM has not been used for some time, the cmos (or whatever) battery may have failed.

When this happens the bios can return to default settings. This would reset date, time, hdd parameters etc. The pc cannot then access the hdd.

If this has happened, leaving the pc powered on for a couple of hours may recharge the battery. If not it will have to be replaced.

You should check the hdd params and if incorrect for your hdd, re-input.

Please advise back on progress.

Good Luck - Keep us posted.

@ Mike Newcomb

You need to know that 5150's (and 5160's for that matter) don't have internal batteries (normally). Some aftermarket suppliers of such existed, but only to keep time; the HDD parameters still had to be set-up via DIP switches on the MoBo or (sometimes) the controller card. There are no BIOS settings.
