RMA or force reallocation

[ShimadaRiku]

smart long selftest had "read failure 90% remaining" in one of my mirrored drive, but reallocated sector is still zero.

Should I be trying to RMA or force reallocation by offline the disk then re-write with

Code:

dd if=/dev/zero of=/dev/da1 conv=sync bs=4096 count=1 seek=4835180

LCC is high, but the green drives have this issue with the heads parking after
just a few minutes. This can and should be adjusted with the wdidle utility
recommended in this forum post.

Since your drive is under warranty, I'd contact Western Digital and follow their advice about
the possibility of an RMA

Your drive is only 2/3 of a year old. RMA. This is a no-brainer.

Also, as Dave says, and as you can find in somewhere around 2 million posts in the forum, WD Greens are not recommended for NAS because of the way in which they park/load, resulting in unnecessary wear and tear in the form of loading cycles.

Its only been used in a NAS for like 2 weeks with head parkting set to 300 seconds. But, was used as a normal windows desktop drive before that for half a year.

Is having just high LCC enough for WD to honor a warranty? it doesn't have any Reallocated_Sector_Ct or Raw_Read_Error_Rate

All the high LCC says is that you used the drive in conditions that were specifically advised against by Western Digital ;)

I would say, as Dave says, if your log shows failed SMART long's, that alone is sufficient for RMA.

Should I be trying to RMA or force reallocation by offline the disk then re-write with

To answer this question, for the general case:

A single bad sector doesn't bother me. Trying to reallocate it is pointless, though. Drives will have problems, that's what ZFS is designed to deal with and fix. A manual scrub might be a good idea, but manually messing with the drive directly most certainly isn't.
An RMA probably wouldn't be granted for a single bad sector. In this particular case, the SMART test failed, so it's probably going to be accepted.

Resilvering atm zzzz, since I am going to RMA that drive I'll play around with it for a bit. :D

 

[cyberjock]

Also noteworthy is the fact that you've gotten two failed long tests, and the test stops on the first error. There could be a million bad sectors after the first error, and you won't know. In your case, it's very likely you have at least 2 bad sectors though.... 38681440 and 38688272.

Just do the RMA. :P
