OK, I have tried everything in my arsenal to get this thing to boot from a hard disk, it just has too many barriers.
It came with a 20MB miniscribe, and the HDD will pass every test under compaq diag, but if you fdisk a new partition, or try to low level format it, it freezes and does nothing.
I have tried different controllers, and such, but does the same exact danged thing.
The drive spins up and sounds healthy enough, and like I said, it passed all of compaq's diag read/write/head tests.
I have tried dos 3.1. dos 3.3, and dos 5.0. Same thing, freezes at fdisk or low level format.
If I try using compaq's reconditioning format option, it freezes up as well.
All jumpers, cables, connections have been triple checked.
This situation is driving me nuts.
Does anyone have any ideas?

Just thought if this machine has a turbo switch which is on -
to turn it off, this usually leads to problems - well on my
computer it does.
Could the HD be locked to prevent writing - don't think that
should lock up the computer though?
Have you tried alternative Partition management programs?

definitley not a turbo switch. Its only a 286. Is it possible that the drive head itself has simply crashed?

ST-225s are notorious for 'stiction' issues:

Yes, I have tried different apps.
It has a miniscribe hdd, and spins up fine.
I will look into the write disable thing, maybe something there.
