I have a microSD card that I use in my mobile phone.  The capacity is supposed to be 32 GB, but for whatever reason, I can't copy more than 1.6 gb, give or take to it.

 

I have tried formatting the card, but no matter that I do, when I try to copy files over (mp3's and videos, mostly), it hangs after it reaches that limit, and then eventually gives me an error message saying that the file can be copied.

 

Even if I take out my microSD and put it into my laptop's card reader, it does the same, despite saying that the card has a 31.2 gb capacity.

 

I've searched online but I can't figuer out what's causing it to do this.  Please help me out here.

Hi

 

Is it the card that came with phone?

Did it ever allow you to copy more to it previously?

 

If the answer to both of those is no, it may be a counterfeit card. That is usually how they behave.

It didn't come with the phone, but I seem to remember being able to copy at least 7 or 8 GB to it at one point when I put my phone in mass transfer mode.

Maybe this can help you determine if that is the issue...

Ok, I'll try it and report back.  This works for the MicroSD cards with adapter right?

When I try to run the program, I select the microSD as my drive, and the "Data Volume" changes to 32037 MB, but everything under that is greyed out, so I can't run the program.

 

Are there any more like this one?

That's the only one that I have used for testing flash memory. someone else may know of another.

 

Regardless, it is sounding like the controller in that microSD card has some serious issues that may or may not be related to its authenticity. I don't think that it is trustworthy.

That seems to be the case.  I can run the program now, but shortly after I start the test, I get the following error:

 

 

Error writing file 'G:\1.h2w', offset 0x0.
It is still possible to verify the test data written up to this point.
(The volume for a file has been externally altered so that the opened file is no longer valid. Code 1006)
Warning: Only 32029 of 32030 MByte tested.
Writing speed: 0.00 KByte/s

That really sounds like the controller went bad. Lots of things outside of your control can cause that to happen.

Hi if micro sd hold only limited data like what you say 1.6gb the rest 30gb is fake. The cards sold cheap on ebay are most likely fake.they sell 512gb card it shows 499gb on mobile the usable area is only 3.7gb. 512gb never made one yet anyway. Not for sold $15.... FAKE..
