Unfortunately I removed some debug code. I inserted it now. It would be nice, if u could upgrade to the newest version of graid5 (some minutes old)... Then debug level 2 should produce more output (each read/write request gets two lines: start and done)... :-) -Arne ____________________________________________________________________________________ Sucker-punch spam with award-winning protection.
