I have the same general problem of my external drive disconnecting after some time, with an error log similar to the one in this bug report. After the disconnect, I have to power-cycle the drive to get it to show up again in My Computer. This is on a Lenovo T61 laptop running Ubuntu 10.10 attached to a LaCie 1GB external ext3 hard drive attached via USB. Here is an excerpt of the log during the last crash/disconnect:
