So, this is not the first time this has happened. My problem is, that after deleting some stuff on my PSP under Linux, the memory isn't freed.
I headed to Filer on my PSP (yes, I have it half-hacked, HENed actually) and found out that the files are not there. SO they are deleted, however the memory is still the same 400 megs, while it should be 1.5 gb. Any ideas except formating the MS?
