I am using a Inclose USB2 hard drive cage, and seeing intermittent errors while writing huge amounts of data to a 120GB drive (typically moving about 500MB/minute, failing between 5 minutes and an hour, with some datasets and not others). Before I waste everyone's time, I would like to locate some test tools that might help me simplify the experiment and better locate the source of the problem. The machine I am doing this on is a non-production system, so I can compile and load special debug kernels, run in single user, turn off services, etc. So, questions:
Are there any USB test tools that will thrash a large, fast usb-storage system in an illuminating way?
Is there a technique to reset the USB card and subsystem quickly, without rebooting the whole system?
Can anyone suggest some revealing experiments?
What specific data would be useful (beyond setup, results, var/log/messages, timing, behavior, etc.)?
I would like to have this well boiled down before submitting a bug.
