Hi I have an old USB memory stick (32MB), it works allright under Core 1; and used to work allright too under Core 2. But today I failed to mount it with "mount -t vfat /dev/sda /mnt/usb/", the output is like below: ----------------------------------------------------------------------- SCSI error : <2 0 0 0> return code = 0x70000 end_request: I/O error, dev sda, sector 0 Buffer I/O error on device sda, logical block 0 unable to read partition table Attached scsi removable disk sda at scsi2, channel 0, id 0, lun 0 Vendor: Model: Rev: Type: Direct-Access ANSI SCSI revision: 02 end_request: I/O error, dev sda, sector 0 Buffer I/O error on device sda, logical block 0 FAT: unable to read boot sector mount: /dev/sda: can't read superblock "mount: /dev/sda: can't read superblock" The kernel version is 2.6.6-1.435.2.3 ----------------------------------------------------------------------- Below is the output of USBVIEW: ----------------------------------------------------------------------- usb-storage Speed: 12Mb/s (full) USB Version: 1.10 Device Class: 00(>ifc ) Device Subclass: 00 Device Protocol: 00 Maximum Default Endpoint Size: 8 Number of Configurations: 1 Vendor Id: 0c76 Product Id: 0005 Revision Number: 1.00 Config Number: 1 Number of Interfaces: 1 Attributes: 80 MaxPower Needed: 100mA Interface Number: 0 Name: usb-storage Alternate Number: 0 Class: 08(stor.)
