I bought an SD memory card 32gb that I didn't know was fake till I used it on my PSP, then I tested it with h2testw to know the actual capacity and it was way lower than 32gb,maybe about 4gb, please how do I restore the memory card back to the amount it can actually hold without corrupting data?

    FWIW, it might be helpful if you added a picture or at least a make/model number of this fake SD card. For all you know this could be a common thing and someone will see that specific card and just say, “Oh! Do this, that and the other…” – JakeGould Nov 6 '15 at 19:19

    "how do I restore the memory card back to the amount it can actually hold without corrupting data?" - You can't. It only can store 4 GB. Are you asking how to make it display 4 GB capacity instead? If that is the case, you can't, not without a way to modify the firmware on the device. – Ramhound Nov 6 '15 at 19:47

If the memory card is fake and only stores about 4gb, then it can't "go back" to 32gb since it never had that much space to begin with. If it was partitioned, you could repartition and reformat.

Check this answer for more information.

And to avoid losing the data on it, you'll need to back it up somewhere else BEFORE you reformat it.

  • Thanks Mark, I know it can't go back to 32 GB, what I was asking was about restoring it to its original space ie the 4gb, how do I do that? – Dipo Nov 6 '15 at 19:05
  • If it isn't a fake or broken memory card, then you can just reformat it in most cases. If it's completely fake, then you unfortunately have to eat your loss. – Mark Buffalo Nov 6 '15 at 19:06
  • Is there a difference between formatting and reformatting, because I've formatted the card a lot – Dipo Nov 6 '15 at 19:08

    @Dipo Repartition it and then format it. – Ƭᴇcʜιᴇ007 Nov 6 '15 at 19:10

These fake-capacity cards are made with the poorest quality components, just good enough to store a limited amount of data for a short time. I would not trust any such card to store data reliably, even at its true tested capacity.

Your best bet therefore is to try to get a refund from the seller.

Your second best bet, for the same reason, is to throw the card away.
