formatting MFM drives on a IBM PC

[emanuel stiebler via cctalk]

Hi,

trying to check some MFM drives I have on my shelf.
Have an IBM PC AT, with an WD1003 controller in it.

So, what is the best(?) or easiest piece of software,
to format the drives, check for bad blocks, etc.?

I think I remember something like "ontrack" for doing it,
but didn't touch PCs for a while ...

Ideas? Links?

Thanks!
