It seems that coredata sql stores can't be read or written from

the user a more descriptive error message?
That is by design.
WebDAV is incapable of supporting non-atomic reads/writes. As such,
there is no useful reason -- and many reasons not to -- store a SQLite
database, through Core Data or otherwise, on a WebDAV based filesystem.
Use an XML or Binary store instead.
The following can be used to test FS type:
int main (int argc, const char * argv[]) {
NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
if (fsInfo.f_flags & MNT_RDONLY) {
NSLog(@"Read only %s", argv[1]);
exit(0);
}
NSLog(@"Type %s", fsInfo.f_fstypename);
[pool release];
return 0;
}
