I've been using the SD adapter that came with my flash card to transfer files onto the Micro SD. The problem is if I use the Micro SD USB drive that came with the R4DS it renders the card corrupted it seems. I've only used it three times and every single time I tried the USB drive either refused to write to the card, hung, or corrupted whatever was on the card in the third case.

Has anyone else had these problems? I'm fairly content with using the SD adapter, but having a micro SD reader/writer would be nice too. I don't want to send the whole thing back to get a replacement either.

 

I had the same problems. it would fail in copying a file, then the card would be corrupted. Stopped using it.

 

I used the R4 reader for a few days, and then it started to freeze my PC whenever I plugged it in. It's not a very reliable accessory.

 

There was apparently a bad batch of the readers. They assumed they all worked, which majority of them do. I've used mine since I got it and it's been perfect. The few bad ones that turned up became enough of a problem that they replaced it with a totally different one. Nonetheless, I was lucky enough to get one of them that has no problems at all.

EDIT: ...this is like, the third time you've beat me to a response, iamwhoiam...making my post redundant..stop fucking ninjaing all over my shit

 

What do you mean? .....

 

had the same problem with the blue reader I got with my r4. first it was freezing my pc then I had issues with corrupted files and directories and then finally it just melted lol literally melted. nuts. just dont use em. not worth it. buy a cheap one from newegg.com or something.

 

I reformatted the flash card and it worked fine. But I am not going to use the USB reader again. Risk just isn't worth it; if it's corrupting files, who knows what else could go wrong?

 

Killed my card ($27)

 

There's already been like 5 different readers they've sent out from what I've seen/read. Apparently this one (link) seen in the review doesn't work according to shaunj66 (link). This is the one I received (link) and it's worked perfectly since I've got it. Then there's the black/grey one just mentioned (sorry, can't find a pic of). I also think there's at least one more I've read that someone got. Not sure what to tell ya since the different ones included obviously aren't consistent enough :/

 

I have one of the blue ones. It's still working fine after several dozen uses, but with a lot of people having problems with it, I'm getting worried if it will fry my microsd one day... I've switched temporarily to an ultra slow 1MB/s reader.
