Hardware Micro sds works in PSP but not in PC, wants format

[EmulateLife]

I have 2 sandisk 16 gb micro sd cards and I use them with Photofast MS Pro Dual slot adapter. I also have other adapters and I have the same issues. The PSP can read the sd cards fine but when I either try to hook the PSP up to my PC with usb or I use an adapter to read them in PC it asks me to format. Tried two computers. I want to add a few games but can't because of this, and I'd rather not format and lose all my games/saves. It makes no sense to me that the PSP can read them fine but computers wants me to format them.

If you are using a dual adapter it probably redoes the formatting to work with that (probably splits the difference, though might interleave).
I am not aware of any programs or handlers for such things, and it probably varies between the various such devices anyway.

Leave it in the adapter and find a pro duo or whatever reader, or leave it in the PSP. If it is slow to read/write in the PSP then go into settings and disable charge when USB connected for as long as you need access to the card -- USB delivering bulk power means compliant devices will reduce speed of reading to handle the excess noise/induction that goes on because of such hobbies..
There should be various options for FTP as well so you could instead go over network but it has been a while since I played with any of those.

Read the adapter manual. You can't use microSD outside of adapter. Especially when you using two cards at same time.

I was going to say the same thing, but the original post mentions having used usb. it's an old post though, not sure if the second poster tried that or not or if he just removed the memory stick adapter and plugged in one of the micro sd cards to the pc.
