    Micro SD Card Repair

    I've somehow corrupted/bust a 32gb micro sd card I got off ebay, and consequently its now only showing up as 8mb!

    I've tried formatting again using Disk Utility and Gparted, but to no avail.

    Anyone had a similar problem, or have any advice?

    Even in gParted when you delete the partitions it still is only 8 Mb.? Cause if that is the case the MBR is corrupt and you might have to get a new one...

    Re: Micro SD Card Repair

    Did you ever manage to store much data on it?

    I only ask, because there are a lot of 'fake' storage devices going around; it never hurts to ask.

    dd if=/dev/zero of=/dev/sdX

    See how much you can get onto it before it fills up.
    There's no place like ~/

    Re: Micro SD Card Repair

    When I first got it, it showed up as 34Gb for some reason in Ubuntu.

    Now it shows up as 7.84Mb

    Tried dd if=/dev/zero of=/dev/sdb, it said dd: opening `/dev/sdb': Permission denied

    Note, I am using a usb adapter that has no 'lock' switch.
    I have also used it in a big SD card adapter, and in my sansa clip via usb. Not success in any of them

    Was a cheap Kingston branded one off ebay, chinese origin possibly, but the other ppl that purchased one gave positive reviews of the seller...

    EDIT: added 'sudo' before that command and it copied 8.4Mb

    Sounds like it's a fake. Often times, sellers or manufacturers will fake partition information so that a card appears bigger than it is.

    Try running it as root.

    Says 8.4Mb

    Shows up in Gparted, but all the options (unmount, format etc) are greyed out.

    I'm sorry to say but you got ripped off. That is a fake card. A real card would not be oversized like that. A real card would actually come up as 31.2 Gb (or something close to it)

    My friend got ripped off on ebay with a thumbdrive not to long ago.

    Sorry about your loss

    Hmm, I've contacted the seller and he said he would refund the cost of the item if I return it to him. So all I lost was the cost of postage x2, which isn't too bad I guess.

    Moral of the story, some things just aren't worth going cheap on (especially imported ebay stuff!)
