WD2002FAEX overheating in ReadyNAS Duo

Hi--

After having frequent RMAs on Seagate drives, I swapped one of the drives of my ReadyNAS Duo (v1) to a Western Digital WD2002FAEX. It's on the HCL, but after the upgrade, I get the following alert emailed to me after the Duo has been on for several hours:

Unexpected enclosure status detected [SURE-CON-NAS]: Disk on channel 1 reports a temperature of 55C / 131F. : Please shutdown the system immediately for service.

The Duo is sitting on an open shelf in an air-conditioned room. If I keep a fan pointed at the NAS, I don't have the issue, but after a few hours of use without the fan, I start getting this alert. The other drive in my Duo (Seagate ST3750330AS) does not suffer from this issue. Before the upgrade (i.e. with 2 of the Seagates), the NAS was operating in the same location/environment without any temperature issue for over 3 years.

I'd consider downgrading to a 5400 RPM drive, but disk access speed is critical for this unit.

Anyone else seeing overheating of the WD2002FAEX? Think WD will RMA it?

Thanks!

    Maybe try connecting the drive to a PC, and see how high the drive temperature is (this and other SMART parameters can be monitored with Acronis Drive Monitor).
