there I was thinking all WD10EARS drives were the one and same. However, it seems there are different “flavours” of the the HDD out there.
I recently, a couple of weeks ago, wanted to purchase 4x WD10EARS HDDs but my local supplier only had 3 in stock. Later on that evening I ordered the 4th drive from another supplier and I was surprised to see that it had a different “Product ID” and a different “firmware level” from the other 3 drives.
Anyway, I built a software based RAIDz (RAID-5 zfs file system) and the “WD10EARS-00MVWB0/51.0AB51” keeps going offline as soon as I start transferring data to the system. The other 3 “WD10EARS-00Y5B1/80.00A80” are behaving normally (as expected).
Initially, I thought it could be a bad cable. But even replacing the cable did not help. Switching the drive to a different SATA II port also did not help.
The following thread “seems” similar to the issues I am having :
Should I return the HDD under RMA and request another “WD10EARS-00Y5B1/80.00A80”???
What are the differences between the two drive types I have?
Any constructive assistance would be greatly appreciated…
