I just put in a 2 TB RAID setup (Adaptec 2410SA 4 port SATA RAID controller with 2 x 1 TB Samsung HD103UJ SATA hard drives). Formatted it as EXT3, kicked off a huge transfer of 900 GB (using cp command) and walked away. Came back to find Ubuntu (7.10) restarted and obviously only some of my files were transferred
Checked the system log (/var/log/messages) and these errors popped out to me:

Sep 18 20:02:08 phyrehouse syslogd 1.4.1#21ubuntu3: restart.
these messages occurred right in the middle of copying those files and right before Ubuntu restarted. sdb1 is the 2 TB RAID drive (drive in question)
any idea why this is happening and how to resolve it?
