thanks for a prompt reply. The message you've referred to indeed has resolved my old problems -- reading from the device seems to be OK now, and it's really fast, ~10-12MB per second. But now I've discovered problems with writing large files to the device. In my original mail I've claimed that writing works and it indeed did, but that was with the kernel version 2.4.19-suse. In a mean time (while I was trying to get the box to run) I've upgraded to 2.4.25 and there something goes wrong with writing. The syslog trace is attached. But it seem to have the very same roots as the read problem I had before. The only difference is that it manages to store some 10-50MBs of data before it crashes. Interestingly enough, the activity indicator on the HD case remains red and doesn't switch off even after I disconnect the USB cable. The difference that I've noticed between the old 2.4.18 and the new 2.4.25 is that the data transfer rates are much higher now (at least as long as transfer takes place). I'm not sure whether this concerns usb-storage driver or the host interface driver.
