March 8, 201214 yr so i've successfully precleared 3 western digital drives (2 EARS, 1 EADS) and had no hiccups whatsoever. then i get to preclearing a samsung f4 drive (firmware updated) but consistently get the following error: ================================================================== 1.13 = unRAID server Pre-Clear disk /dev/sdb = cycle 1 of 1, partition start on sector 64 = Disk Pre-Clear-Read completed DONE = Step 1 of 10 - Copying zeros to first 2048k bytes DONE = Step 2 of 10 - Copying zeros to remainder of disk to clear it DONE = Step 3 of 10 - Disk is now cleared from MBR onward.

March 8, 201214 yr i would attach a syslog but it is GIGS big They compress really well. Zip it and see how big it is.
March 8, 201214 yr Author i decided to run a clear on the drive using hdtune. i was able to create a problem i'm sure happened with unraid. the disk would get "stuck" and start reallocating sectors. ran seatools, drive was bad. oh well, rma here i come!

Glad you found the drive was defective BEFORE loading all your data on it.
