[comp.sys.atari.st] Marginal DMA chips?

tlz@drutx.UUCP (04/23/87)

I talked to Supra about problems I'm having with my hard drive
yesterday (not the usual crashed directories, but subtle errors
like bogus data in files resulting in cherry bombs and TOS 35 errors
when running programs off the hard drive that work on the floppy
they are copied from).  They suggested that "my DMA chip might
be one of those bad ones that doesn't have enough drive
capability on its outputs".  Apparently they are very familiar with
this DMA problem and run into it frequently.  Since the
chip goes for $35-40, I don't want to rush out and buy one
(especially since I have no guarantee that the new one won't have
the same problem) until I hear from someone else that actually
knows about this problem and has resolved it themselves.

How about it?  Are DMA chips "flakey"?  Or is this just another
act in the hard disk circus?
