[SOLVED] External Usb drive not working on any computer

[Jan123]

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):

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 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:

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:

[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.

OK thanks I will probably just send it back to get a new device or my money.
