[Ilugc] USB device not recognized
Hi, I have a 2GB Transcend USB pendrive formatted with FAT32 filesystem. All of a sudden today, the USB device did not mount when I plugged it in. I checked lsusb and the usb device was recognized. But when I executed sudo fdisk -l, the filesystem was not recognized. When I also executed dmesg|tail, I found that the partitions were not recognized. The output of the three commands can be found at http://pastebin.com/MHZtTRH6;. I have used testdisk to recover data, but when I executed testdisk, only my internal hard disk was displayed, I could not choose the USB device. Is there a way to recover the data in the pendrive? -- Thanks and Regards, Hrishikesh Murali ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Which OS do you run? and does the flash drive work on other OS's ? -- Varrun Ramani http://varrunr.wordpress.com | IRC: __goo__ ___ ILUGC Mailing List: http://www.ae.iitm.ac.in/mailman/listinfo/ilugc

Re: [Ilugc] USB device not recognized
I run Ubuntu 9.10 i386 arch. And no, I tried plugging it in a Windows 7 machine, it didn't get recognized. plug in the usb disk and then wait for a few seconds (~ 5 seconds) and see what you have in the kernel log ( run the command dmesg | tail -n 30 on a terminal). Copy paste the output of that command in a reply so that we can see if it is just an error with the partition table (or something similar) or a bigger issue.

Use dd. For example , say your pen drive is attached to the node /dev/sda2 , do something like this : dd if=/dev/sda2 of=drive_backup then you will have all the data on the drive also on the file image drive_backup, you can then try recovery tools on the image.
