I have a SanDisk Mini Cruzer 128MB USB key that won't work in Fedora Core 1. I get this when I plug it into my IBM Thinkpad T40 (USB2): Apr 15 11:06:53 fc1 kernel: hub.c: new USB device 00:1d.7-1.2, assigned address 8 Apr 15 11:06:53 fc1 kernel: usb.c: USB device 8 (vend/prod 0x781/0x7100) is not claimed by any active driver.

Now when I try `mount /dev/sda1 temp/`, it sits for a few minutes, and finally returns this: 'mount: /dev/sda1 is not a valid block device', and /var/log/messages has this: Apr 15 11:07:57 fc1 kernel: hub.c: USB device not accepting new address (error=-71) Apr 15 11:08:02 fc1 kernel: usb-storage: host_reset() requested but not implemented Apr 15 11:08:12 fc1 kernel: scsi: device set offline - command error recover failed: host 0 channel 0 id 0 lun 0 Apr 15 11:08:12 fc1 kernel: SCSI error: host 0 id 0 lun 0 return code = 6050000 Apr 15 11:08:12 fc1 kernel: ^ISense class 0, sense error 0, extended sense 0 Apr 15 11:08:12 fc1 kernel: sda: I/O error: dev 08:00, sector 0 Apr 15 11:08:12 fc1 kernel: I/O error: dev 08:00, sector 0 Apr 15 11:08:12 fc1 kernel: unable to read partition table Apr 15 11:08:13 fc1 devlabel: devlabel service started/restarted I have had some success at formatting these types of key in Linux, but fdisk doesn't show sda at all (it cannot read the partition table). I tried the key on FC2test2, where I could fdisk it. But I still could not mount it on either OS. Any ideas? Thanks, Forrest
