Formatting your 4GB Memory Stick to FAT filesystem will make it faster in your PSP compared with PSP’s default format type FAT32.
To check if you still have FAT32 format:
- Connect your PSP via USB (make sure your memory stick is inserted)
- Right click your PSP’s drive and click on properties
- If you’re already in FAT format and you still experience lags in game or in XMB, you might want to try FATMS Patch.
- If you still have FAT32 format make a copy of all the files and folders (including hidden folders/files) of your memory stick and back it up on your PC.
- on Windows Explorer (or any folder open) click on Tools > Folder Options
- Click on VIEW Tab
- and choose/check Show hidden files & folders (see screenshot)

- Show Hidden Files and Folder
- Click on Start > RUN then type CMD
- on the CMD window type format x: /q /fs:FAT
- x is the drive letter of your PSP
- there will a prompt asking you about cluster. Choose Y to continue
- Just follow the instructions on screen.
- Copy all the files and folders you backedup before and paste it in your newly formated PSP Memory stick
* I used Windows XP when formatting the memory stick because when I tried it in vista the format completes but it never shows games/homebrews from ISO and /PSP/GAME folders.

Jeff.. sinubukan ko to.. backup ko ISO games at SAVEDATA lang.. tapos nung format ko na.. balik ko ulit ung backup ko.. sabi sa PSP there are no games daw waaaah!
pano to?
try mo reformat ulit, alam ko issue yan sa mga class A na memory sticks. Suggest ko format mo muna sa PSP, then format mo ulit using the method above, then put the games one by one…
bro share ko lang regarding sa class A 4gb, pagka format mo s fat16 sa properties ng psp drive mo (ex.: F:) gamitin mo yung error checking tool at check mo pareho yung check disk option bago ka mag transfer ng file s s psp.
Happy New Year!

Ok na PSP ko. Ang ginawa ko format ko using PSP then copy yung mga generated folder sa PC then format naman using DOS. After that, balik lahat ng mga files from backup.
Cheers!

Hey guys, I formatted my memory stick/card.. so basically all the folders and files got totally wiped out.. so I created new folders for music, photo, games and videos… sadly I can only put music and videos, and they are the ones that only work. I tried putting games in CSO and ISO format and it doesnt work, as well as the pictures that I put, I can’t view them.. the games doesn’t show once I insert my memory stick/card in my psp.. my friend told me that I need to download a certain patch, but he forgot what its called, I guess for the other folders that needs to be in the memory stick/card.. so anyone has a suggestion of what I can do? any help will be higly appreciated
thanks!
