Unlock sandisk 1g memory stick produo

hi i cantt format my psp sony memory stick produo 8 gb

Put the card back in the computer and format it using FAT (not NTFS) format. In the format menu, you'll see the file system pull down option, choose FAT and try and format it again.

Thanks Mark

1. Try re-formatting your memory stick from your PSP console. A memory stick that is formatted from a PC or other hand held console sometimes cause incompatibility problem with the PSP.
2. If your PSP still can not read the memory stick, try checking your memory stick by using your friends PSP and see if they can access the memory stick.
3. If the memory stick can be accessed by your friends PSP then there is a problem with the memory slot of your PSP.
4. The only way to check the contacts of the memory slot of your PSP is to disassemble you PSP and take out the mother board.
   

You need to check again how you are erasing with the PC.Try opening the the memory stick folder on your pc, and deleting some shots one by one.You should be asked each time to confirm you want to delete.You can then check if they have actually been deleted by looking in your recycle bin.
I don't ever clear the memory stick of my cybershot outside of the camera. After download, I delete with the camera.That way I know my card will stay properly formatted for my camera.

is it compatebal with the psp

probably ur MSPD card is not legit, there are many inferior chinese models out there which ****. 
Buy only sandisc or Sony ones.

Try formatting the Memory Stick. This should work.

Picture quality depends on camera and photographer's skills.
Memory cared / stick will store data in digital form and thats all an it has nothing to do with picture quality.
So rest assured about memory stick and take good snaps in your trip.
Have a nice time.

Try a couple of these trial downloads, to see if the pics are recoverable, but it's possible that the psp formatted it to it's own file format. http://www.cardrecovery.com/?rid=google&kid=cr0119 http://www.freedownloadmanager.org/downloads/memory_stick_recovery_software/
