I just looked back at your original problem report, and I saw this in your log file: Jan 9 06:34:05 client kernel: usb-storage: Command WRITE_10 (10 bytes) Jan 9 06:34:05 client kernel: usb-storage: 2a 00 00 4f 09 57 00 00 80 00 Jan 9 06:34:05 client kernel: usb-storage: Bulk Command S 0x43425355 T 0x14ea L 65536 F 0 Trg 0 LUN 0 CL 10 Jan 9 06:34:05 client kernel: usb-storage: usb_stor_bulk_transfer_buf: xfer 31 bytes Jan 9 06:34:05 client kernel: usb-storage: Status code 0; transferred 31/31 Jan 9 06:34:05 client kernel: usb-storage: -- transfer complete Jan 9 06:34:05 client kernel: usb-storage: Bulk command transfer result=0 Jan 9 06:34:05 client kernel: usb-storage: usb_stor_bulk_transfer_sglist: xfer 65536 bytes, 16 entries Jan 9 06:34:30 client kernel: usb 1-3: control timeout on ep0in Jan 9 06:34:35 client kernel: usb 1-3: control timeout on ep0in What on earth are these messages doing here? 1-3 is the usb-storage device in question. There shouldn't be any control transfers going on at this point, only the bulk-out transfer. This looks very strange...

Do you see this same sort of thing in the log with max_sectors set to 16? Just for kicks, see what happens when you set max_sectors to 2. (!) Also, I can't remember if you've already posted this information. Could you send the output from lsusb, or else the contents of /proc/bus/usb/devices, with your drive plugged in?
