I had a 2tb EARS drive in an external usb enclosure that I have just added to my system, during the copying of zero's to the drive during preclear, the 4 other disks in my system spin up, and stay spun up even if I'm not accessing them, and the read count goes up on each, the parity stays spun down?

 

Advice? should I stop preclear? let it run?

 

As I'm on 4.7 I didn't jumper the drive and used  preclear_disk.sh -A /dev/sdg    to kick it off.

 

Thanks

Let it run.

 

What is probably happening is that a PC on your LAN is scanning the directories on those disks for changes, and whatever was in the disk buffer cache is being displaced by the preclear script reads and writes, so the physical disks need to be re-read.

 

Just let it finish,  Sounds like you are doing everything right.

Thanks Joe L,

 

Have let run, 52% into the Post-Read, 22hr43mins in, so far so good.

 

Cant say I noticed this happening when I precleared the other drives, but that was awhile ago. Just ordered 2 new EARX Hdd, hopefully pick them up on the weekend, and will see what happens when preclearing them next week.

 

Cheers

 

 

Ahh, no good, it hung at 72% for about 5hrs, the time clock didn't move, it had been going for 26hrs(so over 30hrs actually) by that stage, got my wife to close it down, will see what happens with the new drives next week, picking them up tomorrow hopefully. Am not home so can't post any reports.

 

Edit, might try adding a jumper and not using the -A option, what do you think?

don't bother.    Not worth the risk of data loss.
