There are probably better ways to do it. We're using a rather simple error handling, where we retry for a maximum of five seconds on read error.

It's possible, yes. But we have a plan for dynamic watermark handling that takes into account disk errors and the time used for reading.

This is annoying. I use a Toshiba 40G myself, and this never happens to me. I keep the Archos in the handlebar bag on my bicycle while riding to work, and I can assure you it shakes a lot! It's puzzling that it differs so much between different people/units.
