Errors - scrap or fiddle...


Recommended Posts

Posted

 

I have a drive that has started generating errors on the UNRAID dashboard (accomapined by a noticable lag if its a video playing and is presumably being rebuilt on the fly).

 

I've ordered a new drive to replace this one, is there any thing I can do to re-use this drive in my array or is it time to scrap it?

1266 pending failed sectors. Based on that, I'd say take it out of the array.  You can try running several preclears on it to see if the pending failed sectors are corrected, but I wouldn't trust the drive anymore.

Thanks.  I'll give the pre-clear a go but will probably just scrap it.
