March 31, 201115 yr Hi! I connected my new WD20EARS (Parity) via a SUPERMICRO AOC-SASLP-MV8. The disc shows a temp of 0 degrees in the main window. Besides unmenu shows a temperature. In the log I get: Mar 31 18:23:44 unRAID emhttp: disk_temperature: ATTR_Temperature_Celsius not found (Other emhttp) I already found this thread: http://lime-technology.com/forum/index.php?topic=6934.0 root@unRAID:/boot# unraid_info.sh -d cmdOper: cmdResult: bName:/boot/config/super.dat sbCreated:1292534450 sbVersion:1.1.0 sbUpdated:1301588613 sbEvents:68 sbState:0 sbNumDisks:8 sbSynced:1301555835 sbSyncErrs:0 mdVersion:1.1.1 mdState:STARTED mdNumProtected:8 mdNumDisabled:0 mdDisabledDisk:0 mdNumInvalid:0 mdInvalidDisk:0 mdNumMissing:0 mdMissingDisk:0 mdNumNew:0 mdResync:0 mdResyncPos:0 mdResyncPrcnt:0 mdResyncFinish:0 mdResyncSpeed:0 ============= UnRAID Disk 0 =========== diskNumber: 0 diskState: 7 diskName: diskModel: WDC WD20EARS-60M diskSerial: WD-WCAZA4043525 diskId: WDC_WD20EARS-60M_WD-WCAZA4043525 diskSize: 1953514552 rdevNumber: 0 rdevStatus: DISK_OK rdevName: sdc device: /dev/sdc rdevModel: WDC WD20EARS-60M rdevSerial: WD-WCAZA4043525 rdevId: WDC_WD20EARS-60M_WD-WCAZA4043525 rdevSize: 0 rdevNumErrors: 0 rdevLastIO: 1301588613 rdevSpinupGroup: 0 spinstat: SpunUp freespace: 0 pct_free: 0.0000% pct_used: 0.0000% Age: 27 hours Temperature: 0 read_smart_if_spun_down: Yes Is the disc okay or should I be worried?

March 31, 201115 yr Author Hi! I found a new thread in the Synology-Forum. It looks like this is somehow related to a new revision of these discs: WDC_WD20EARS-60M You can see it by the "60"M. Bye.
March 31, 201115 yr Interesting, I haven't run into this yet (and I go through a LOT of EARS drives in my client builds). My knee-jerk response would be to return the drive or at very least send a strong complaint to WD about it. It is definitely important to be able to know your disk's temps. Does the drive also not report a temp when connected directly to the motherboard or to a different controller card?
March 31, 201115 yr Author Hi! I will contact WD. But it seems to me, that is has something to do with the way the software reads the temperatures. I can see unmenu shows the temp right. Bye.
April 1, 201115 yr Hi, i´ve the same problem. My drives are WD20EARS 60M too ... I´m really new in Unraid systems and i just startet testing my system last night. If you find a solution for this, post it here please. I will do the same, but i have not much experience i think...
April 22, 201115 yr Hello everybody same over here, bought 1 new drive 2 weeks ago,, at first sight it's oke,, and shows temperatures, also in the first 20 hours of a Preclear the preclear shows no failures ,, i did a parity check ,, and in the main menu of UNRAID (Not UNMENU) it shows 0 degrees. In Unmenu it seems to be oke? It's a newer revision WDC_WD20EARS-60M_WD-WCAZA404**** Directly on a Supermicro C2SEE. Model Number: WDC WD20EARS-60MVWB0 Serial Number: WD-WCAZA4046721 Firmware Revision: 51.0AB51 changed the sata cable, changed the power connector formatted the drive and checked it in a Windows pc , did a test with HD-Tune,, showing also 0 degrees?did a SWAP a the local pc-store for this drive. Got another with a big differance in serial number, but still with 60M_WD-WCAZA and everything repeated first 20 to 24 hours of preclearing it shows the temperatures,, but after the parity check it looks like the temp sensor has burned away from stressing the drive? Is this possible? is it a bad revision?

Is this possible? is it a bad revision? Probably just how unRAID is reading the temperatures. (unMENU and the preclear script both use smartctl to read the temperature)
April 22, 201115 yr I am having exactly the same problem. I have 6 WD drives (type WDC_WD20EARS-00M) that report the temperature fine. The 7th WD drive (type WDC_WD20EARS-60M) reports it temperature as 0 degrees in the standard unraid webpage. However, the unMenu main page reports the temperature correctly for all drive.
April 23, 201115 yr This happened to my friend with a new EARS. After 24 hours it was fixed (with a replacement drive from Amazon)
