SD card won't format to the correc size

Hi,

I have an 8gb SanDisk SD card that I want to use in a raspberry pi that I'd previously used with an older version of the Raspbian OS, and I wanted to reformat it so I could put the latest version on.

However, Windows 8 will only let me format some random 56mb partition, and I cant make it larger or smaller. "This is weird," thought I, so I went into disk management and took a look.

Currently, there's a 56mb partition that I cannot shrink, extend or delete, and a 7-and-a-bit GB of unallocated space that I cannot format.

No matter what I do to the 56mb partition, whether it's partitioning with NTFS, FAT or exFAT, nothing is working. :cry:

Am I being an idiot, or is something wrong here? :??:

Many thanks to anyone who replies :)

  1. use the win32diskimager-binary

    the other partition that you can't use is in Linux format.
  2. SD Formatter 3.1 and 4 both failed. So did DiskPart. and I'm not touching that russian software (not because it's russian but I don't speak a'yor language so mistakes are bound to happen).

    There is part blame on Microsoft for this inability to format anything other than FAT and NTFS. I also can't understand why the Raspberry Pi team for don't realise this as an issue that not everyone has the abaility to solve.
    It is very frustrating.

    well then tell me because i cant figure it out.
  5. Ok first try this
    download the raspbmc installer
    open it , select your SD card and press restore for format and then format it using SDFormatter

    if that does not work
    download EASEUS Partition Master it has a trail
    delete the partitions on the SD card and then press crate and format the SD card.

    good lock

    - That didn't work for me. Although, interestingly, the card has now jumped from 56MB to 70MB!?

    I have just downloaded EaseUS Partition Master 9.2.2 FREE edition.
    After some wrangling I eventually *touch wood* appear to have a 14.8GB SD card now.

    - I'll let you know if the SD card works in my camera/Raspberry Pi!
  9. Wow its been a while.. but good luck

    I only came across this thread on the 5th of July.
    - But I managed to flash Raspian Wheezy (I am a totally Pi Newbie) onto the aforementioned SD card, and it seems to be working fine.

    Thanks again for the help!
  11. your welcome.
  12. I found this (link below) about how to use windows tool DiskPart from a command prompt to re-partition and re-format my sd card: http://raspberrypi.stackexchange.com/questions/1446/how-can-i-reformat-my-sd-card-to-use-it-normally-again
  13. I had he same issue, 125MB available. I popped my card in my digital camera and formatted the card nearly 8Gb available now.
