I just got an Apple ProFile hard drive. It seems to work, although I don't
have an interface card for it yet.
But, it squeaks. You know, like a water pump on a car before it blows
(that's the pump bearings, BTW). Does anyone have any check-out/maintenance
tips for this drive? The hard drive is labeled "Seagate model ST-506".
Thanks!

Sounds like the ProFile card is just an ST-506 hard drive interface. A
ST-506 drive is REALLY old. I'm not an expert on the old hard
drives/interfaces, so I'll let someone else figure all that out, but I can
tell you that it is very old. Does the ProFile need a seperate power
cord(does it have it's own ps), or does it get power from the Apple II?
And if the ProFile is just an ST-506 interface, does that mean I could just
plug one of my old ST-225's or other ST-506 type drives intoa ProFile card?

If that's all that's wrong, try lubing the ground strap/ spindle juncture.

Yes, As long as it has more cylinder and heads. You'll have to low level
format after you install it.

NO! no lube ever, the graphite stuff on that button is good enough.
But what makes squawking noise that button is worn to shape of the
little shiny spinning button, take the board off, and undo that
grounding strap, file the button until it's reasonably flat and
reinstall it.
I have done very often when I find a old drives like that.

Oh, you can. Still 5mb or 10mb. :)
Remember, all older MFM, ESDI and some early SCSI drives always need
annual or bi yearly LLF job.

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.

It was. ST stands for Seagate Technologies. The ST-506 was the first
practical harddrive and became so popular that everyone standardized on
that interface and we still call it a ST-506 interface.
If you use a drive with fewer heads or cylinders than the 506, you will
probably get an error and it won't work. It should be easy to get a drive
with more heads and cylinders then no problem except the extra heads and
cylinders will be ignored and you won't get the benefit of the extra
capacity. That's a small price to pay for not having to try and hack the
software!

Unfortunately, no. The Apple 5MB ProFile uses a Seagate ST-506 mechanism;
however, in the Apple tradition, the Seagate logic board is replaced by an
Apple-designed version with an Apple parallel interface. Since the
heads and stepper motor on the ST-506 are connected directly to the Apple
logic board, replacing the mechanism with anything other than another
ST-506 would be difficult.

That is surprising. No, not that Apple did such a thing, but that
Seagate did not distinguish the model number of the drive with a suffix
letter or different number altogether. Unless Apple, in their 'infinite
wisdom', bought standard drives and just threw away the Seagate logic
board and installed their own.

Geez! An original 5 Mb Seagate 506! I used to have a maintenance
manual for it but I haven't seen it in at least 10 years. I also have a
couple of NIB 506s somewhere. It's probably easier to just stick in a
newer MFM drive that has more tracks, heads etc and use it, a Seagate 225
should work fine. A part of it will be wasted but that's no loss.
The squeal is probably coming from the ground strap on the bottom
spindle. Try putting a bit of powered graphite on it and see if that
helps. Or you can bend the strap to change the tension. Some people just
remove it all together, it's not recommended but I've never heard of it
causing a problem.
