Hello Tech support,

I have an issue with one of your WD caviar black WD6402AAEX.

I am using two WD6402AAEX with two WD6401AALS in RAID 10 configuration.

i am using an intel server/raid controller intergrated with my asus P8P67 deluxe motherboard.

for some unknown reason, one of these drives (WD6402AAEX) need to be constantly rebuilt according to the raid controller software.

i have tested each drive with your WD diagnostic software and none of them come up with faults. No grinding or abnormal noises apparent.

I put the drive back into the array and rebuild the array, but within a week one of the drives seem to go offline and need to be rebuilt again.

i have no crashes or issues with system stability which would indicate data loss.

what stikes me as a harddrive fault is that i used these drives in an amd system before and the same issue arised. thinking it was an AMD raidxpert issue. i switched to an intel system, but the issue has carried over.

i have had these drives for about 11 months now and the issue started two months ago.

do you have any advice on what to do at this point?

Thank you for contacting Western Digital Customer Service and Support. My name is Edgar G.

We do apologize for the inconvenience. The Caviar Black drives are great drives and were designed specifically for desktop computers and not intended or designed for a RAID environment. The RAID Edition drives (among other features) has a feature called TLER and the Desktop drives do not. One of the main differences is the amount of time the drive is allowed to recover from an error.

It may be possible to use a Desktop drive in a RAID environment; however, your RAID controller would have to support and accommodate the drive.

Please see the link(s) below for related information from our online knowledge base.

If you have any further questions, please reply to this email and we will be happy to assist you further.


this would explain my issue of constant rebuilding of the drives.

so should i just rebuild as dual raid 0?

what should i do with my four WD caviar blacks?

IIRC, there was some tool that lets you enable TLER on the drives, even though it isn't "officially" supported by WD.

Otherwise, I'd sell, sell, sell. Mechanical hard drives prices have SKYROCKETED because of flooding in overseas factories. The price/GB has nearly doubled in the last month.

EDIT:

Here's a thread with a discussion of the tool:

Two RAID-0 arrays is one option... but remember to backup!

If you're confident with selling them, now might be a good time to upgrade to SSDs.
