Hi, I have Sony 8Gb pen drive. I was trying to make it usb win 7 bootable drive using command prompt and messed it up. Now I have two comps with Win and Ubuntu on it: On win7,it shows up under disk management but not able to format. On ubuntu i have drive disk utility, gparted, fdisk and dmesg; nothing could help to format the hard disk. I get this message: [ 402.263947] usb 2-5: device descriptor read/64, error -110 [ 417.553939] usb 2-5: device descriptor read/64, error -110 [ 417.816654] usb 2-5: reset high speed USB device using ehci_hcd and address 3 [ 430.443970] usb 2-5: USB disconnect, address 3 [ 430.443997] sd 6:0:0:0: Device offlined - not ready after error recovery [ 430.444014] sd 6:0:0:0: [sdb] Unhandled error code [ 430.444018] sd 6:0:0:0: [sdb] Result: hostbyte=DID_ABORT driverbyte=DRIVER_OK [ 430.444024] sd 6:0:0:0: [sdb] CDB: Read(10): 28 00 00 00 00 00 00 00 08 00 [ 430.444039] end_request: I/O error, dev sdb, sector 0 [ 430.444045] __ratelimit: 21 callbacks suppressed [ 430.444050] Buffer I/O error on device sdb, logical block 0 [ 430.444149] ldm_validate_partition_table(): Disk read failed.
