OK, well i've deleted a 5 track album, so that should free up a few megs.

Now trying to sync i am getting a bunch of errors.
During the sync the empeg builds the music database, emptool shows "Rebuilding databases" after a short while the empeg returns to normal operation displaying "invalid file format", but emptool still shows "rebuildings databases".

After a short while emptool then shows:
3100 Rebuild databases returned an error: Connection timed out1260 Drive 0 size: 3910M, free: 32585K, used: 3878M (99%)

At least the file delete operation has worked, it used to say
1260 Drive 0 size: 3910M, free: 1365K, used: 3909M (99%)

Is 35Mb enough space for the database rebuild to work?
