I've worked with ST-225's a lot. It's a 20 meg MFM hard drive, one of the
most common XT configurations. In fact, many other manufacturers (Miniscribe,
Tandon, etc.) made "clone" ST-225's; that is, they had the same hardware
configuration.
To run it on an XT, you need an 8-bit MFM controller card. This card will
have its own BIOS to support it. Also, you likely will have to low-level
format it under that card's electronics. (I can help you with that if need
be.)
The Tandy 1000 is a special case as far as hard drive controllers are
concerned. Its IRQ for the hard drive controller is non-standard, so your
average HD controller will not run on the T1K. I tried it once on a T1K SX
and had no success at all. You either have to have a controller for the T1K's
or do a hardware modification (warm up that soldering iron) to change its IRQ
to that of the T1K.
To run it on an AT or higher, you can use the 8-bit controller card, but you
will need to set your drive setting to "Type 1" or "Not Installed" since it
has its own BIOS. Better yet is to use a 16-bit MFM controller card as it
won't likely have an on-board BIOS and you can configure it thru CMOS.
