a consequence of differencies in the exact chip models and/or firmware versions. My device identifies itself as "P: Vendor=05e3 ProdID=0702 Rev= 0.02"
On the chip reads: GL811E

I'm beginning to believe it's most probably some strange timing quirk. I seem to remember Alan and David both mentioning timing at some stage.
The advantage of mine the way it is, is I have a 100% guaranteed way of tripping it every time.
The cross-sector boundary is not the only failure mode mine exhibits. It also locks up on insert quite a bit, but not reproducibly and when it does sometimes the 2.4.25 kernel oops' with some kind of hotplug race. It often depends if I insert the usb cable before the IDE disk has done it's init cycle. It's bloody flaky. My other enclosure that uses a Prolific chip works rock solid 100% of the time <sigh>
I now have a serial console setup so I can try and capture the oops anyway.
Next project is to start stuffing some delays in the usb stack and usb-storage module and see if I can settle it down.
It's nice having a reproducible failure mode anyway.
My device has GL811USB stamped on it. But it identifies it the same as yours in the above string. Rev= 0.02 also.
Off to do some testing now, hope to have some more results in the morning.
