    External Usb drive not working on any computer


    Hi,

    I am not sure this is the right forum, but maybe someone can help me fix my Toshiba usb drive with Linux. I have formatted it to fat32 after I bought it and used it under Linux. I connected it to Windows 7, my Computer crashed (I don't think this is related to the usb drive) and I can't use my usb drive anymore. The file system doesn't show up in Windows nor Linux. But I can see the Usb device under both Computers.

    lsusb gives me (it's device 12):
    Code:
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
    Bus 001 Device 002: ID 413c:a005 Dell Computer Corp. Internal 2.0 Hub
    Bus 001 Device 003: ID 413c:a005 Dell Computer Corp. Internal 2.0 Hub
    Bus 001 Device 012: ID 0480:a007 Toshiba America Info. Systems, Inc. 
    Bus 001 Device 004: ID 0b97:7761 O2 Micro, Inc. Oz776 1.1 Hub
    Bus 001 Device 005: ID 413c:9001 Dell Computer Corp. 
    Bus 001 Device 007: ID 0b97:7762 O2 Micro, Inc. Oz776 SmartCard Reader
    but fdisk doesn't show it.
    "sudo modprobe usb_storage" didn't work
    if I unplug it and enter "dmesg | tail" I get:
    Code:
    [18383.992333] usb 1-8.3: new high-speed USB device number 12 using ehci_hcd

    Then I replug it and enter "dmesg | tail" again and it gives me:

    I still have my warranty, but I need my data, so please help if you can.

    Thank you

    Whatever the cause, but this drive definitively took a hit:
    Code:
    [18442.873473] scsi 8:0:0:0: Device offlined - not ready after error recovery
    The device is not ready, this is why fdisk doesnt show it.

    As for the warranty:
    It will most likely only cover the hardware. So in the best case you get your money back or a new device.
    But not your data.

    It now depends on exactly how important and valuable this data is.
    One *could* gamble, take the external case apart (Which potentially voids the warranty) and connect
    the drive via a different usb<->sata adapter or directly via sata and see if the harddisc is recognized.

    Or you could send the device to a professional data rescue service. Which costs a bit.
    You must always face the curtain with a bow.
