How to undo hack on fake memory card

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?

1FWIW, 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 – 2015-11-06T19:19:07.870

1"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 – 2015-11-06T19:47:23.757

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 – 2015-11-06T19:05:51.920

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 – 2015-11-06T19:06:56.443

Is there a difference between formatting and reformatting, because I've formatted the card a lot – Dipo – 2015-11-06T19:08:15.070

They're the same thing. :) Although technically, you could format a blank hard drive, and all future formats would be a "reformat." Most people use both terms interchangeably, so everyone should be able to understand what you mean. – Mark Buffalo – 2015-11-06T19:08:45.007

1@Dipo Repartition it and then format it. – Ƭᴇcʜιᴇ007 – 2015-11-06T19:10:32.303

So the memory card is gone forever:( – Dipo – 2015-11-06T19:11:02.933

How do I repartition? – Dipo – 2015-11-06T19:11:17.870

Not necessarily. Like @Ƭᴇcʜιᴇ007 and I said, you can try to repartition and then format it. – Mark Buffalo – 2015-11-06T19:12:13.743

Thanks guys, it didn't work, so the memory card is a legit fake, but thanks for the answers – Dipo – 2015-11-06T19:38:29.013

"Reformatting" will not help. Reformatting simply tries to create a new file system within the number of blocks reported by the card. What is desired here is to change the number of blocks reported by the card. Reformatting or repartitioning will not do that. To get the card to report its true capacity you would have to modify the card firmware. – Jamie Hanrahan – 2015-11-07T03:06:15.163

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.
