[comp.sys.ibm.pc] Noisy Powerdown on ST-251

mjv@cbnews.ATT.COM (Mike Vehonsky) (08/03/88)

	I recently installed an ST-251 in my AT-clone.  When I powerdown
	the system, the drive makes a fairly loud GRRRRRRRRRR sound for about
	three seconds.  It this the sound of the automatic head parking
	"feature"?  It sounds more like the heads being unmercifully pounded
	into oblivion.  It isn't due to the controller (OMTI 8240) since it
	sounds the same without any controller cables attached.

Mine has made the same noise on powerdown for two whole years. It's
still working fine. In a recent issue of BYTE, they reviewed 40 MB hard
disks and noticed that the ST-251 made a noise which sounds as we describe.
I guess it's a "feature". In any case it does not seem to do any harm to the
drive or the data stored therein.
