Thanks, and also to the other poster who suggested this. Unfortunately I
don't seem to be able to repartition, when do I:
# fdisk /dev/sdc
it seems to hang and dmesg shows the following:
SCSI device sdc: 2031616 1024-byte hdwr sectors (2080 MB)
sdc: Write Protect is off
/dev/scsi/host2/bus0/target0/lun2:<6>usb.c: USB disconnect on device 00:07.2-2address 2
hub.c: new USB device 00:07.2-2, assigned address 3
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 3
scsi: device set offline - not ready or command retry failed after bus reset: host 2 channel 0 id 0 lun 2
I/O error: dev 08:20, sector 0
I/O error: dev 08:20, sector 0
unable to read partition table
Similar problems occur if I try to make a filesystem using something
other than mkdosfs.
Am I doing something obviously wrong? It could be the card reader is
fundamentally incompatible with the card for some reason, I may see if I
can arrange to try it on a Windows box as a diagnostic measure.
Thanks.
Steve
