USB Storage - Crashes on Large Transfers
I currently have a work around for this. I was just wondering if someone knows how I can track down why.
I have an external USB drive case with a DiamondMax 10 200Gbyte drive in it. When I try to copy digital photos and mp3 from my CD archive using nautilus (about 40 Gig) it runs fine for about 300 files then the drive and/or my computer lock up and I need a reboot. (And power cycle the USB device) I also get some nasty dump errors in my error log (Below)
If I slow down the speed I'm sending data to the device I don't get this problem: ie
rsync --progress -arv --bwlimit=800 siren:/u5/Photos /media/usbdisk
(Which as worked for about 1400 files so far.)
Here are some of the errors I get:

I have a feeling I'm overloading a buffer somewhere. But I have no idea. I tried two different computers (one with USB2.0 and one with USB1.1) both get the same problem. And the same work around works.
Any one know how I can debug this? With getting different error messages I don't know where to start.
