January 12, 201214 yr I replaced a working 500gb disc (disc 14 in my array) with a new WD 2TB drive last night and started the expansion. When I woke this AM, the drive is flashing red and shows 288 errors. The one thing I didn't do this time, was run preclear on my new drive first. A few months ago I did a couple expansions that froze, but when I precleared the discs and repeated it, it worked. (http://lime-technology.com/forum/index.php?topic=16249.msg150448#msg150448) Here is a snapshot. I rebooted the computer immediately before I started the expansion and yet somehow the syslog is still 1.8 MB the last 90% of it just repeats the same error, so I cut that part to make it fit. What went wrong? I guess I'll preclear the disc, and try again, but I don't understand why its failing if I don't preclear first. I have done dozens of expansion, but until the last 2 most recent expansions I didn't have to preclear the disc to get an expansion to work. Thanks in advance! syslog_truncated.txt

January 14, 201214 yr Author Ok, well I'll start the preclear and let you know what happens. Can anyone think why all my drive expansions are failing UNLESS I preclear first? In the past, this hasn't been necessary.
January 16, 201214 yr Author Ok the preclear worked and showed no errors - it took 27 hours (is that about right for a 2tb drive?) I'm now rebuilding the drive, but its going a ton slower than normal. Its been almost 24 hours and its at 50% now, running at about 5,000KB/s If my memory serves its usually like 40-60,000KB/s My equipment is pretty new: Mobo: SUPERMICRO MBD-X8SIL-F-O CPU: Intel i3 540 Clarkdale RAM: Kingston 4GB DDR3 1333 Power and cooling 750 Watt PS 3 sets of Supermicro CSE-M35T-1B drive cages with 15 drives SATA cards: 1) Supermicro-AOC-SASLP-MV8 SATA2 Serial ATA II PCI-Express RAID Controller Card 2) Monoprice SATA2 Serial ATA II PCI-Express RAID Controller Card 4,000KB/s is way too slow right?
