Sony PSP file transfer inaccurate transfer progress


Having a bit of a issue with Debian Squeeze and transferring files to the Sony PSP..Hook up PSP to USB port and Debian mounts it..I go to drag a 125 meg mp4 to video folder..Copy windows takes about 10 seconds to transfer it..Exit USB mode and there is no video there. Go back into USB mode and look at video folder on the PSP memory stick and there is no video..It vanished..lol.. From another suggestion after copy progress closed I right clicked PSP and unmounted it.. It error-ed saying device was busy and could not unmount..Looking at light on PSP i see memory stick is still being written to..i wait for light to stop flashing..About a minute or so..Then am able to unmount it..Go to PSP video and theres the video ready to be watched..
So..Debian isnt accurately showing the copy progress...Its showing complete when it isnt..I have to watch the light on PSP to know when it is truly finished...Any ideas what is going on here?? a Linux problem or a PSP problem..

A Linux-to-USB-to-PSP problem.
To me it sounds like Linux transfers throught the USB cable, then the PSP takes it and and sticks it to the memory stick.
In theory, Linux IS done transferring the file, but the PSP has yet to utilize it and put it on the memory stick. When you do an unclean unmount, PSP is like WTF am I doing, since it assumes when the cable is removed that it should be ready to play, hence the incomplete file download.
Basically Linux sees it has a 3-way straightforward transferral, while in reality, it is a four-way transferral requiring the PSP to actually install it.
Make me wonder if the PSP has a temporary folder that it keeps somewhere.

Some proof, however credible, in lies in the fact that when you download something from the Playstation Network, that it has to download & install it.

Unless you can find some PSP-Linux protocols somewhere, I'm afraid you may be stuck with watching the blinking light.
Just my opinion, subject of course, to being incorrect.

Cheers,

leopard

Well..I would think If that were the case..That it transfers all data first then writes to the Memory Stick..That it would do it no matter what OS..Linux,Mac,Windows. And PSP only has 32 megs of main memory. Unless it creates a swap/virtual memory on card..But like I said..I dont see why it would be any different on a different OS..I know Im not the only person with a PSP using Linux..lol..So If any of you out there ..Do you have this same issue?

Lol, I have a PSP-3000. And actually from PSP-2000s' on up they have 64 MB of memory. Are you using a MagicGate supported stick? And yes, if the protocols do exist, that may very well fix the problem. I don't really care about it though.
