    I purchased my PSP back in January and have updated by system software twice over the past year. The first time I upgraded my 1 GB card dropped down to 951 MB. The second time I upgraged (v3.71) my card now is at 943 MB (?).

    How do I recover all the lost space on my card due to the upgrades?

    Thanks for your help.

    hmmm - seems strange - I would format it, see if that works. If not are you sur its a genuine stick? If it says magic gate unknown (or something) then its fake.

    if you'll notice, any storage media is never actually at its entire capacity, you'll see an 80 gig harddrive will never hold 80 gigs, usually just a little under, say 74 or so, due to the master file table and such...haha, if you look, a lot of hard drives will say "UP TO.." how ever much it is. My one gig card only holds 900 something megs also, just somethin we gotta live with

    mem sticks are like bottles of water

    even though it has the space you cant fill it up all the way.

    but the best thing you can do is format it if not

    try putting it in your comp if it has a mem stick port thingy and formatting it on there.

    yup my 4 gig is like 3878 free space or sumthin like that.


    most likely if u kept formatting it or sumthing and lost more space u probably lost that in the formatting process

    which u cant get back. but im not sure most likely that might be it

    Formatting will not lose space.. Many people think it's bad..

    All it does is write 0's to each sector, allowing them to be rewritten.

    i think you guys are missing the point....he's not saying its full capacity but that the capacity has decreased.

    What did you use to format the memory stick either times? If you formatted in the PSP, the format is usually FAT16 (4GB and lower). If you formatted on your Windows PC, the format is FAT32. I believe FAT16 uses less overhead than FAT32. However, FAT16 is also more inefficient in utilizing space than FAT32.

    Another explanation for the decrease in space is bad sectors.

    Also, just checking the free space using the PSP is not a very exact method to confirm the total capacity of your memory stick. While the PSP is connected to your PC via USB, you can check the total capacity by right clicking on the drive and selecting Properties.
