Subject: IDE hard drive keeps stopping!

I have a Toshiba MK234FC 100 Meg IDE hard drive in my 386-25 system.
About 5 times a week or so when I'm accessing the drive, the drive will
physically spin down and stop! Then spin back up right away again.
It seems to do it the most when a lot of disk access is going on.  I called
Toshiba about it, and they thought it was a problem with the host adapter
and not the drive.  From the way I understood his explantion, there is one
line from the host adapter to the drive that handles the interupts.  If there
are a lot of interupts on this line at one time, the host adapter could be
getting confused and doing some sort of reset to clear things up.
Has anyone else experienced any of these problems with IDE drives?
The host adapter is made by TMC Research and has a 4 floppy controller as well.
