Preclear error

Featured Replies

I have successfully precleared 6 of my WD 3tb drives but a few are getting an error during the process. Im not sure what the error means so im hoping someone can give me some advice.

 

Ive attached 2 print screens of 2 drives that have had the error. Im running version 4.7 of unraid but Ive learned that 4.7 doesn't support 3tb drives so as soon as the other preclears finish ill be updating to beta.

 

Here are my system specs:

log

The drive stopped responding...  The last attempt at reading it ended with 0 bytes read. 

The out4 and out5 variables printed in the error should not have been zeros

but part of the unRAID signature in the MBR having very specific expected values.

 

I would guess if you attempted to get a smart report from it right now it would not respond.

smartctl -a /dev/sde

 

You could try power cycling the drive, or try re-seating the cables to it, but it might have just died an early death.

I get this message when I type that request in;

Probable ATA device behind a SAT layer, try an additional '-d ata' or '-d sat' argument.

 

Ive read problems with me sata cards im using. It seems unlikely the drives r dead, its happened to 4 of them and a 5th one freezes 31 seconds into the prelear each time.

 

The drives that failed this time did the same the last time I tried too, stopping at around 18 hours.

Yes, I agree, not likely the disks themselves.

 

If 4 disks, then perhaps the power to them shares a splitter, or a drive rack.  It could also be the disk controller is not seated firmly in the MB connector.

 

As far as the smart command, you could try

smartctl -d ata -a /dev/sde

 

I'm going to guess it will still not get a smart report.

Not meaning to hijack this thread, but I am experiencing the same issue with my three brand new 3TB WD drives.  out4 = 00092 and out5=00092 in my case, but same result.

 

When I try the smartctl command I get a report from each drive that claims no errors logged.

 

Must be something to do with the SATA controller built into the motherboard I am using (an Asus P5GD1, which means Intel 915P chipset and ICH6R controlling the 4 SATA ports)

 

In my case, all drives fail after step 10 of preclear (28 or so hours after it began).
