I've been using USB key drives for over a year now. Recently, I got a new JetFlash Model: TS256MJF2A, and now I am having trouble with the JetFlash and a Memorex thumb drive I've been using for over a year. I don't know what to make of this -- whether it's a kernel problem, a problem with my machine, or what. Any help you can give would be appreciated. Please Cc me on replies.
The JetFlash maybe a hardware problem because I couldn't reformat it from three separate boxes including a Windows XP box. It dies partway through. When I tried copying some files to the USB drive, got tens of thousands of lines of messages like the following in my /var/log/syslog file: Nov 26 15:09:36 faerun kernel: scsi1: ERROR on channel 0, id 0, lun 0, CDB: 0x2a 00 00 00 1d 01 00 00 80 00 Nov 26 15:09:36 faerun kernel: Info fld=0x0, Current sda: sense = f0 3 Nov 26 15:09:36 faerun kernel: Raw sense data:0xf0 0x00 0x03 0x00 0x00 0x00 0x00 0x0b 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 Nov 26 15:09:36 faerun kernel: end_request: I/O error, dev sda, sector 7425 Nov 26 15:09:36 faerun kernel: Buffer I/O error on device sda1, logical block 7363 Nov 26 15:09:36 faerun kernel: lost page write due to I/O error on sda1 Nov 26 15:09:36 faerun kernel: scsi1: ERROR on channel 0, id 0, lun 0, CDB: 0x2a 00 00 00 1d 02 00 00 7f 00 Nov 26 15:09:36 faerun kernel: Info fld=0x0, Current sda: sense = f0 3 Nov 26 15:09:36 faerun kernel: Raw sense data:0xf0 0x00 0x03 0x00 0x00 0x00 0x00 0x0b 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00 Nov 26 15:09:36 faerun kernel: end_request: I/O error, dev sda, sector 7426 Nov 26 15:09:36 faerun kernel: Buffer I/O error on device sda1, logical block 7364 Nov 26 15:09:36 faerun kernel: lost page write due to I/O error on sda1 Nov 26 15:09:36 faerun kernel: scsi1: ERROR on channel 0, id 0, lun 0, CDB: 0x2a 00 00 00 1d 03 00 00 7e 00 ....numerous lines skipped...

I tried doing a df on the device. I can't remember the precise size I saw, but it was much higher than the actual size. I am running a locally compiled, unmodified 2.6.8.1 from kernel.org. The rest of the system is Debian unstable. I tried compiling and using 2.6.9. It use /dev/uba and /dev/uba1.
