Re: [PLUG] corrupted partition table on CF card


this is what dmesg says when i insert the usb reader with card inserted:

hub.c: USB new device connect on bus2/2, assigned device number 3
usb-uhci.c: interrupt, status 2, frame# 187
usb_control/bulk_msg: timeout
scsi1 : SCSI emulation for USB Mass Storage devices
  Vendor: SIIG      Model: CompactFlash Car  Rev: 0113
  Type:   Direct-Access                      ANSI SCSI revision: 02
Attached scsi removable disk sdb at scsi1, channel 0, id 0, lun 0
SCSI device sdb: 125185 512-byte hdwr sectors (64 MB)
sdb: test WP failed, assume Write Enabled
 sdb: unknown partition table
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 3

this is what i get when i try mounting /dev/sdb1 (which is where it normally
shows up)

mount: /dev/sdb1 is not a valid block device


this is what i get when i try dd:
dd if=/dev/sdb1 of=cflash_out
dd: opening `/dev/sdb1': No such device or address

what do you think?
