    SD CardReaders and recovering corrupt data.

    It appears the my 16kg SDHC card is playing up, ive lost the most recent 200 or so photos.

    Put the card in, opened the most recent folder, some alised and messed up file names (not a good first sign) but could see all the thumbnails. Selected what i wanted, tried to drag and drop. 'Error, cannot find/read file etc'. Tried on or two individually, same.

    Card out, card in, cant see them any more. Same with the card in the camera.

    Did it once before just in the camera were a load went missing to the exact same point, but the then came back with a power of and on again and i was out and about so i thought little of it and then forgot about it till today.

    Going to havea go with the recovery software, and will post back on that.

    MY Only worry now is its the card reader thats at fault. Although it has worked fine before, and works ok with other cards. Its just a cheapy of ebay, which may be a false economy.

    Re: SD CardReaders and recovering corrupt data.

    There was a thread on HEXUS some time ago about fake USB drives/flsah cards that had been formatted to show a larger capacity than they really had. I'm not saying that this is the case here, but a lot of those drives appear on Ebay.

    If you are familiar with Linux, there is a utlity called photorec that you can use (not used it myself) or a list of windows tools here http://www.thumbdriverecovery.org/ (may not be exhaustive) and if the card is reporting an incorrect size, there may not be any data to recover.

    For info about fake flash drives http://fightflashfraud.wordpress.com...apacity-flash/ but note hat the program is a test program not a recovery program and it will over-write anything there

    Re: SD CardReaders and recovering corrupt data.

    Hmm - my advice would be to try one or more of the recovery programs (some, IIORC are available as trial versions so you can see what coukld be recovered if you buy the full version) I'd start with the linux tool (but I am familiar with linux)

    Once you have recovered as much as you can, try reformatting the drive or use the test program to determin what its real capacity is.

    There are also some USB drive inspection tools (again. I am only familiar with the Linux ones) that will give the Vendor Id (Vid), Product Id (Pid) and if there is one, a serial number. The pid and vid may help you find out a little more about the drive. Windows 7 also reportsd the Pid and Vid somewhere (possibly under properties).

    I have a similar problem with a usb SD card adapter, put in a Maxel 4 gig sd card and it corrupts it every time!! Have to reformat it in the camera and then it's fine.

    Try Zero Assumption Recovery? http://www.z-a-recovery.com/ ; the free version will recover photos from a memory card and worked well when I used it on a goosed card.

    I would recommend trying this application.

    I use this for recovering data all the time on peoples drives and SD cards and I find it does the job quite well.
