    Arrow USB disconnection safety

    When you have a device plugged into a USB, there is that option to safely disconnect the device. Do you have to this procedure with the PSP when it is connected to a computer?

    I've found that you only need to do that if you're running less than USB 1.1 on the device (you'll know that you are if you are)

    Other than that. If you're not transferring data on any USB device you can just disconnect / unplug any USB device including the PSP.

    USB is completely hotswapable like that.

    It's just an option for people who want to do it. There is a supposed risk that you might corrupt data if you just yank it out. However lots of people just disconnect it by pulling it out, it's personal choice really. If you want to play it safe, it only takes an extra 5 seconds. I'd recommend you do it safely for important memory sticks etc.

    It's mainly to get Windows to flush any write caches. By default though, I believe write caching is disabled on USB drives - or at least, is supposed to be. I've had "delay write failed" errors before, even though Windows shouldn't be using delayed writes...

    Also ensures that applications don't have open handles on anything in the USB drive. Usually not a big issue however.

    ok. the reason why i asked this is because a teacher once told me that if you don't safely remove your portable devices, you will lose memory on the portable device, in this case the psp memory stick.

    O.O losing memory as in ?
    For me, I usually just press X when all the files transfers are finished..

    as in your 1GB memory stick will eventually (constantly removing the device without safely removing) not have 1GB of space when empty.

    this was his advice, i'm just asking you guys if it's true with psp memory sticks.

    That sounds kinda retarded. You can't permanently lose space that way. Even if you DID lose something, formatting always clears all space.
    First:
    Sony 3.90>1.50> 3.52 M33>3.90 M33> 5.00 M33-6> Gen-D3
    Secondary:
    Sony 3.50> 1.50>3.52 M33>3.90 M33> 5.00M33-6

    if you're worried there is an option to have it ready for quick ejection
    How old is your teacher from experience many of them have gotten misinformation in their heads if they're over 35

    Not physically, but the filesystem may get damaged if you don't "disconnect safely".
    I'm no expert in FAT filesystem driver implementations, but ignoring that, if it can damage the filesystem, it may be possible to cause all data to be lost on the drive, or weird things such as loss of space to occur.
    Note that as this is not physical damage, reformatting will always resolve it.
