hummm.....You might want to try downgrading to another OE firmware. Other then that, I think you'll just have to find a flash1 formater, and run it via the recovery menu. I am almost sure I saw one on QJ the other day. If not, I'm sure someone here may be kind enough to write one for you (my compiler is broken right now, and I really don't trust myself with writing to the flash). You also may be able to re-format from windows, but I'd be really scared to do this because it my be a slightly different format. I know that flash0 and flash1 both use FAT16, but I don't know if Sony might have moddified the file structure somehow. There were rumors of a change when 3.00 came out.

Flash1 is not formated by re installation nor downgrade.

Install to 3.03 OE or higher, go to the configuration, send flash1 to usb, then go to windows and format the psp.

And if that doesn't work, do what theaceoffire said, but run a chkdsk on the PSP. To do this -

• Click on Start, then Run.
• Type in "cmd" (minus quotes) into this box.
• In the box that comes up, type "chkdsk X:/" (minus quotes), but replace X with your PSP's drive letter.
• If it finds any errors, that might be the problem.

Thanks to pj1115 for the suggestion (I know he's long gone now though )

although your best off error checking first then format as a last resort

p.s. if in win xp you can right click on the memstick select properties and select error check, or for format right click on drive and select format, and format as fat.
