32GB micro SD card - after a few runs everything is corrupted, files missing, StartPortableApps crashes

I do not know if this is an issue with my card, with windows 7 x64 or what. If I install the full suite, nothing will run after it is done installing. Windows reports that StartPortableApps.exe is not a valid win32 or win64 file. I look in several of the subdirectories and they are empty. I notice that the PortableApps directory and the documents directory are both set to System and Hidden, and I do not know if that is normal operation. I will be traying the latest beta to see if that is different.

Anyone else have issues with a 32GB micro SD in a USB sleeve?

Where from?

That sounds very much like a disk issue. Where did you get it from? If it's new from a regular shop, it's probably a dud. If it's second hand or from eBay or such, it's probably phoney.

32GB micro SD card new from Hong Kong

I got the card on ebay from Hong Kong. I have opened a case to see if I can get another one sent or just get a refund. The thing with this is, I can copy 20GB or music files to the card and they copy fine and play fine. The portable apps installer, however, seems to hide and make things system which corrupts installations.

Strange

There should be nothing different in how installing portable apps and putting music on works.

Dud Card

I would say three possibilities:
1. The card is dud
2. You have a virus
3. both

I still think number 1 is the culprit, just by virtue of the fact that you got it from eBay. It's notorious for those sorts of things. Anybody, isn't there a program you can download to verify the real capacity of your memory card?

I think executables are more read/write intensive that simply copying and playing MP3s, but probably given enough time your MP3s would begin to cease working too.

Can you install the suite to your local hard drive without any issues? If so, then it's definitely the card.

Oh, btw, I forgot to mention that some time ago I bought a 4gb micro SD from eBay, only to discover that it was a really a 2gb card. Sufficed to say, today it's in a landfill somewhere because it ceased working not long after I bought it.

Maybe also the USB adaptor …

I’ve had similar experiences (intermittent failures) when switching from 4GB to larger capacity SDHC cards. The USB adaptors you can get all pretty much look alike, but some seem not to fully support the SDHC (> 4GB) standards. I’ve used one labelled "LogiLink SD/MMC/RS-MMC" and a no-name "SD/MMC/RS-MMC USB 2.0" adaptor which both showed failures.

I then bought a "Rydges" (also Chinese built) blue adaptor (Link) that was advertised as supporting "full SDHC". It is labelled "(e)Com SD/MMC/RS-MMC USB 2.0" and works fine with cards up to 32GB.

So it seems that some of those USB card adaptors out there don’t fully support SDHC and produce intermittent failures. None of the ones I now have here shows "SDHC" on their labels, btw. It seems one should look for those containing a "CR0015" (whatever, maybe chipset), all adaptors labelled as having a "CR00007" seem not to support SDHC (only SD up to 4GB) correctly.

Unfortunately, those adaptors that don’t work correctly sometimes only show their fault when the OS tries to access data above the 4GB boundary. I recommend using some kind of "disc test" on an empty card to be really sure. This is also a good method to find out how fast these actually are (big differences!), so you can be sure that running a larger application (like OOo) from the stick is anyhow feasible.

Also, some of those SDHC cards out there seem a little flakey. I’d advise to go for a "Class 10" card (has a "10" inside a circle that is open to the right) for speed. Cards I found working well are from SanDisk, Kingston, and Transcend.

So far for my findings, hope it helps a little.

that sucks

Can you try installing the suite to somewhere, say, "New Folder" on the desktop and then copying the contents from there to your micro SD card? Or have you tried that yet?

Thanks for all the suggestions

Thank you. The people on this sight are very helpful and I thank you.
Conclusion: The card is a phoney. I contacted Kingston and read all the numbers on the card to them and they said it was a China phoney. Ebay buy protection is giving me my money back.
In other news I found a Class 10 Kingmax Micro SDHC 16GB on Amazon, So I bought that and I'll see if the speed of a class 10 makes everything better and good.
Thanks again

A message from Kingston. The card is phoney

Fake SD cards

There has been a rash of fake MicroSD cards in a variety of values...16GB, 32GB, 64GB.

ALL ARE MISLABELED AND FORMATTED TO FOOL YOUR COMPUTER.

To SOLVE this problem:

Download and use h2testw

It's a free download, and will test and verify (read-write) ANY SD card, or fixed drive thumb drives, USB drives or anything you suspect isn't what is says it is.

EXAMPLE

MICRO SD 32GB will be recognized as a 32G card by your computer
BUT.....
It's a 4GB relabeled, and formatted to SAY it's a 32.

RUN THE TEST (h2testw) and then Get a refund from whoever sold it to you!.

Dr Dave Smith
