The ST-506 is a 5mb disk and is the first built by Seagate, I believe.

Unless you are able to patch the software, you should be able to replace
it with an ST-225 or any other MFM drive, provided that the new one has
at least 306 cylinders and 4 heads. More is OK, but less will cost you
storage space.

If you can patch the software, your options are much wider.
