Cant think of where to put this, so if is in wrong thread, can a mod please move?

Bought a 32 GB Micro SD card from 'The Bay' (probably 1st mistake there) and al;l looks good when i get the card.

Pop it into my card reader and copy all from my existing card (16 GB) over to it. All goes well there and all appears ok. Then go to copy over my music library as that was the reason I bought it and that's when things are starting to go odd.

The library looks like it has copied over correct, yet when i run music player, it sees no music. Browsing with a file manager shows that the MP3 music folder is empty. I have been through these steps about 3-4 times and the result is always the same, regardless of whether i transfer the files with the MSD card in a reader or in the phone (Galaxy SGS2 running DarkyROM2).

I did some Googleing and downloaded a program called SD Formatter (which was recommended by someone. This shows the card as formatable to 30.1 GB (as expected). Can run this and copy files over, yet when i put it in the phone, i am told the card is corrupt and needs formatting.

What the heck is going on here? Am i doing something fundamentally wrong or i have got a duff / bogus card from the seller? Haven't left any feedback yet either
 
I would guess the card is borked.

I would look for genuine 32GB samsung micro SD cards if you manage to get a refund and not from the place you bought it from but from a regular big etailer.
 
I thought there were a vast number of fake high capacity flash memory wossits on the bay.

Since I tend to use flash memory for useful stuff the saving vs chance of messing up something important... Just wouldn't...

The one I heard of was it's often a low capacity which has been screwed about with so it appears to be a high capacity but when writing over its REAL capacity it goes back to the start and writes over itself again.
 
Am running it now, but is taking a wee while to run. Has taken 3h15mins to write the 32 GB and looks like it will take 2h15mins to verify.

Isn't looking good so far. 1.8 GB ok and as I type 11.9 GB lost with 11.9 GB overwritten.

Sounds like a 2 GB card made to look like it's something it isnt.

Will post up the full results in the morning tomorrow.
 
My 16GB card was fine


Test finished without errors.
You can now delete the test files *.h2w or verify them again.

Good to know i can trust the card.
 
Number 1 rule is to never buy memory from Ebay, you have plenty of legitimate places to buy them from at a cheap price £15 ish for a 32gb on certain sites. Hotukdeals are posting them all the time.
Open a dispute ASAP from the seller and buy from a known etailer.
 
Cost me £15 for the card.

Had heard that there are dodgy cards on the bay, but thought I would risk it for a biscuit.

Anyhow, here is the final report from the scan

The read/write speed is pants too.

Have a moan at the seller then a moan at ebay and dont ever buy high capacity flash memory off the bay again :P
 
Learned lesson there, but not cost me a penny as seller refunded me no quibbles.

Will buy genuine Sammy one after payday comes.
