 Posted: Fri Mar 09, 2007 3:34 am Post subject: SCSI HDD temperature question |
 |
|
Hello folks,
I'm concerned about the heat of a SCSI drive that is in almost constant
operation. This drive is being used in an Akai digital sampler model S5000
and space is tight inside these things. The drive is an IBM ddys-09170 9GB
80-pin 10,000rpm model, connected to the Akai's native 50-pin internal SCSI
port via a 50-80 pin converter. It has been in use for a good 6 months
without problems but the heat from this unit worries me a bit - it is too
hot to touch for prolonged periods. But then I suppose these drives were
originally designed to be used in servers and therefore built to run
constantly.
As the Akai has no option through software to let the HDD go into idle mode,
the drive is running at 10,000 rpm day & night. A Jaz 2GB SCSI drive
attached externally to the same machine seems to handle its own power saving
features of its own accord. Looking at the technical sheet for the IBM
drive, it supports spinning down into idle mode but from what I can gather,
only through software.
Anyway folks, two questions:
1. Does the drive sound much too hot?
2. Anyone know of a way I might force the drive's power saving features on,
maybe through jumpers on the option block?
Any replies greatly appreciated. BTW, I managed to wire a small fan up to
the Akai's PSU just to get a bit of circulation. There's zero room for
another fan.
Cheers,
Doc White. |

Somewhat. Does your system support SMART? If so, you could ask the
disk if it thinks it is running hot.

Have you considered adding an additional case fan to force additional
cooling over the drive?

As for supporting SMART, I think the drive does but the Akai S5000 has very
basic SCSI implementation - it is a digital audio sampler in a 19 inch
rackmount unit, 3 units high, and the only diagnostic feature it has is to
stop working if there is a fault on the SCSI bus. You can set the SCSI ID
and termination, and that's it - no other features. The drive can be heard
performing a self-check routine every few minutes - this is a feature of the
drive and not the Akai. As for the fan, there is no room, it's a real tight
fit in that case.
If it sounds hot to you folks, I'll find a slower drive - or put it in an
external enclosure - it's the peace of mind I need, I can't afford to kill
the Akai.
Thanks for the reply mate. |
