Problems with WD 1TB WD10EACS (green) drive as internal replacement

[carrot]

I tried a WD 1TB WD10EACS (green) drive as an internal replacement.

The first time it formatted and worked.

All subsequent restarts fail at the self test routine.

The screen goes to a temperature self test subroutine where it shows:

Max allowable temperature: 122
Unit intitial temperature: 491

Then goes through a 5 minute cool down routine that fails, then there is no way to skip it.

491 is a spurious number; it never changes and the drive is cold. I suspect that the format process bypassed the temperature test the very first boot up.

I assume that the drive is giving an incompatible temperature signal and the self diagnostics don’t let the system get beyond that.

Replacing the original drive fixes things. I am on CE:15:05, the last but one release.

Any ideas?

Sounds like the temp sensor on the drive has gone bad. You may want to try returning the drive as defective and getting another.

Agreed.

Also, since the specific model was not listed by the OP, its difficult to determine the "normal" temp range, as the HR21's run cooler than the HR20's. If it alllows a max temp of 122, then it will most likely continue to have issues in any HR20, whereas it should be fine in any HR21 (better ventillation and cooling fan placement).

I have two of those drives running. One in an HR21-200 and one in a HTPC. Haven't had a problem with either. My average temp on the HR21 is about 105...and my HTPC runs at about the same internal temps (40c).

I'd suggest taking the drive out and running a SMART check on it...if it reports errors...then RMA it away.

Thanks all.

It was a bad drive that probably failed during intitial formatting. I remember it making lots of noise and taking tens of minutes. The new drive did the formating a a few seconds.

PS I got the same over temperature message with NO drive so the drive was probably not communicating at all and my PC bios could see something but it had zero size and no information.
