Fake micro SD cards

Does anyone know how to spot a fake micro SD card?  My wife bought two SanDisk micro SD cards whilst in the Philippines. One of these failed completely and cannot be recovered. SanDisk has advised me that the cards in question are fake. What should I be looking for to avoid this happening again? :

Re: Fake micro SD cards

Yep. That's what SanDisk told me too; but that is not very helpful. These cards were bought in the Philippines in a shopping mall from a shop selling cameras, mobile phones and accessories - the same type of shop you would perhaps buy from in the UK. The assumption is, that as it sells a range of photographic goods and their memory cards that they are an authorised dealer.

Re: Fake micro SD cards

Many of the Flashcards and SC cards purchased on eBay or bought in vendor stands thorughout Asia are fake. They buy small memory cards like 1GB, then program the architecture to make them seem like 2, 4, 8, 16 or 32GB. You usually discover something wrong when files begin dissappearing after you exceed a limited size or the file names are retained, but the files won't open (because they only contain such info as filename).

Flash drives and SD cards in all forms can be tested with a utility software program called H2testw.exe , http://www.heise.de/software/download/h2testw/50539 . It gets rave reviews by PC Magazine. I purchased 3 supposedly 16GB micro SDHC cards on eBay that were fake from Chinese vendors. When I tested them and filed for buyer protection with eBay, the money was refunded quickly.

Here is the post-test report on one of the fake 16GB cards.

The media is likely to be defective.

Re: Fake micro SD cards

[ Edited ]

Thanks. That is a very good explanation. My wife bought two micro SD cards whilst in the Philippines, strangely, one of them (so far) works perfectly! The one that failed could initially be read by the camera, as the images were visible on the LCD; however, when she next switched on she got the message clean card or format.  The card was sent of for recovery, but turned out to be unreadable; they tell me that the controller on the card has failed - their program (and the one on my computer) reports 250 Mb of data which cannot be accessed. This last would be consistent with the images my wife said she had previously viewed on the card prior to failure.

 

I've got to accept that the images may never be recoverable and that the card they're on is fake. What I'd really like to know is how to spot a fake!  :smileysad:

Re: Fake micro SD cards

Follow drlucky's advice. Buy from well known legitimate vendors or a source that has some type of buyer protection.

Re: Fake micro SD cards

I recently bought a 32GB micro SDcard from a company in the UK trading as >mirosdcardsonline.co.uk< . The card was a fake with maximum storage of 2GB! I downloaded a test program, "h2testw_1.4", which works fine with windows 7 and confirmed that the card was faulty and confirmed the maximum storage capacity of 2 GB (i.e.. Not 32 GB as marked on the card!).

This test program will identify the problem and give you the necessary proof to demand a refund based on the fact that the seller is selling counterfeit cards.

The company I dealt with, Micro SD Cards UK Ltd of Luton, UK, trading as >microsdcardsonline.co.uk< did not reply except to ask me to return the "evidence" and then they would not reply when I asked for my refund. I had to obtain a charge-back via my credit card company which took two months but eventually I got my money back. Always pay by credit card and you are then protected against this type of fraud if the supplier does not refund you after a reasonable period.

In addition to advising not to deal with this company under any circumstances (it is run by a Mr. Hamilton and a Ms Griffith who never answer a phone call or respond to emails!), I would urge all readers to buy micro SDcards from a legitimate retailer or from a bona-fide online trader like Amazon. I subsequently purchased a genuine SanDisk 32 GB card from Amazon which is all that it should be - a first class product.

Please also be warned that microsdcardsonline.co.uk also sell branded SanDisk cards (the one I purchased was unbranded) but I would guess that these would also be counterfeit, but at a higher price, so I would advise that you shouldn't take the chance!

This is scary, although this is not anything new about fake memory cards.

Re: Fake micro SD cards

I'm buying on E-Bay 2 Micro SDHC 64Gb, seller posted pics of items into theyr original packaging. The packaging seems original,but...I see that, on seller pics, Micro SD are all black, but if i try to search this product on the Sandisk site i can't found SDHC 64Gb (Sandisk show max memory is 32Gb for SDHC type) but only SDXC 64Gb. The packaging seem really original, now i wonder: Did ever Sandisk produce Micro SDHC 64Gb?

Re: Fake micro SD cards

:smileyhappy:   Hi Fab1972,  

 

Dear member of SanDisk Community, welcome.

 

Well, friend, as you suspect (it's also very cheap?), is fake.

 

International Protocol of the SD Association, it's for all brands, and 64 GB, is SDXC only.

For more detail on this topic, you can check here: https://www.sdcard.org/home/

 

I guess that it's a microSDHC 4GB, to which they added 6, or something similar.

 

If you bought it, then can make the following tests and verify:

 

1-  Format with (free): USB Flash SD Formatter 4.00, http://filecloud.io/jqtu1byc

 

Also you can try, with three portable utilities (free), whether they are fakes:

 

2-  USB Flash H2testw 1.40,            http://filecloud.io/jl4fhn9b          -It's the classic utility, but for 64 Gb, it takes ~ 4 hours.

3-  USB Flash FakeTest 1.09,          http://filecloud.io/n074g3x5       -It's similar, but has a quick option, and takes minutes.

4-  USB Flash ChipGenius 4.00,     http://filecloud.io/rqa7etmv        -All internal data, of your UFD.

 

Luck, and then you tell us, what happened, please.

 

Regards, Alfred.                                                             (Google translated)
