DIRECTORY ERROR!! - HELP

Im aware there has already been discussion about this here before but none of the suggested answers in 2007 have worked for me.

Im running jjos free on an mpc1000 and I have a project that up until yesterday was saving perfectly. So, basically when I turn the mpc back on the next day, in track mute all the pads in bank A are still fine, but the stuff i did in bank B is gone. When I load the sample back into their correct places, the MPC remembers the sequences I recorded and everything goes back to normal, but i still cant save so that i dont have to reload the samples every time. Really weird and annoying.

Im wondering has anyone experienced the $30 jjos fix this problem? I tried saving the project to a new folder but just got the same directory error.

If the new $30 jjos has worked for people, have you lost all of your jjos free work on instalment of the new os?

Apologies if people are tired of hearing about this problem, just cant afford to lose any more work as im using it for live in a weeks time.

Thanks in advance.

What is the $30 fix?

Changing to a different JJOS is not the fix for directory errors, 99% of the time you just need to get a new disk/card, or need to reformat the existing disk in JJOS. Does the problem persist if you save to a new disk?

The other week someone mentioned they got directory errors when they had a space at the start of a file or folder name, but generally speaking everything is fixed with a new disk.
