Hi all,

 

This is my first time seeing issues arise with preclear. I've only precleared one disk prior and everything was successful. This time my first preclear failed during the pre-read stage, then I ran three more preclears just to be sure (1 cycle, then 2 more, hence separate logs) and they were all successful but had an increasing number of sectors re-allocated. 

Do I need to be concerned about the sector re-allocation or does it mean that preclear worked as it should and "fixed" the bad sectors?

 

I currently have one 14TB parity drive and my intent was to swap it out for this 18TB one. It's still sitting unmounted because I'm not sure if I need to RMA the drive. I trust this forum can help me figure that out.

I have attached the three preclear logs and the SMART report for your pursual.

 

 Thanks for your help!

Although in theory reallocated sectors are not always a problem I would be concerned if:

• there were more than a small number.   On a new drive I would expect 0
• the number was not stable and kept increasing

since you say this is a new drive I would be looking to RMA it.

Thanks for your advice @itimpi. I'll RMA the drive then, just to be safe. 

Definitely don't want a parity drive (or any drive for that matter) failing on me anytime soon if I can avoid it.
