I ran the disk speed test and all drives except sdb were above 100 MB/s. Drive sdb was 25 MB/s...ran the test again and it was 1.24 MB/s! I decided to switch this drive to a slot where one of the higher performing drives was and also replaced the jumper and it gave 90 MB/s and the drive that I moved into sdb old slot was still pretty high at 107 MB/s. Strange...still not sure if it's safe to build the array?? Perhaps the problem was a bad connection with the jumper?? Despite the speed anomalies, do my preclear results look ok? I built the 15 Drive Budget Box listed here http://lime-technology.com/forum/index.php?topic=7998.0 my latest speed test results are below... /dev/sdb: Timing cached reads: 3556 MB in 2.00 seconds = 1778.70 MB/sec Timing buffered disk reads: 324 MB in 3.01 seconds = 107.66 MB/sec /dev/sdc: Timing cached reads: 3572 MB in 2.00 seconds = 1786.67 MB/sec Timing buffered disk reads: 326 MB in 3.00 seconds = 108.61 MB/sec /dev/sdd: Timing cached reads: 3558 MB in 2.00 seconds = 1779.21 MB/sec Timing buffered disk reads: 318 MB in 3.02 seconds = 105.31 MB/sec /dev/sde: Timing cached reads: 3326 MB in 2.00 seconds = 1662.72 MB/sec Timing buffered disk reads: 272 MB in 3.01 seconds = 90.43 MB/sec /dev/sdf: Timing cached reads: 3552 MB in 2.00 seconds = 1775.83 MB/sec Timing buffered disk reads: 354 MB in 3.02 seconds = 117.39 MB/sec /dev/sdg: Timing cached reads: 3564 MB in 2.00 seconds = 1782.33 MB/sec Timing buffered disk reads: 340 MB in 3.00 seconds = 113.26 MB/sec

I noticed they are all EARS drives. Did you place the jumper on pins 7 & 8? Should normally take about 30-40 hours to preclear a 2TB drive. Were all 6 drives pre-clearing at the same time? Yes, all drives have jumpers on pins 7 & 8. I started 4 drives preclearing at same time including the slow one (sdb). After the first two completed, I started up the next two. Never had more than 4 running at same time. Drive sdd was precleared twice because I forgot to save the results the first time.

Just spent the past week preclearing six 2TB drives. Not sure if the results are good or not, but one of the drives took forever to finish.....about 3-4 time longer than the others. Do my results look ok? Thanks, jeff preclear.results.txt
