It's very consistent. Apparently your drive doesn't like to transfer data from sector 18743651. (I got that number by taking the start sector address 0x011e0120 from the second line in the log and adding 0x43 = 34304/512, the number of sectors successfully transferred when the error occurred. Subsequent attempts encountered the same error at the same sector number. This is just beyond the 9 GB mark.) Instead it's sending an invalid signal on the USB bus. > Looks like the stack retried a couple of times, and then decided to > drop the request and to deliver an error to the upper layers. That's right. > Does this help. It's not clear whether the real source of the error is in the drive or in the enclosure. One thing you could try is to reduce max_sectors to 128.
