This is a re-upload of the programs originally developed to detect delays in Maxtor's MXT540A hard drives. Due to the recent reports of delays in other hard drives I am providing these programs again. They will not detect delays of less than about .05 - .06 seconds accurately. The tests are of two flavors. HDDELYW3 was written to detect a delay caused by inactivity- while HDDELYW4, was written to detect a periodic delay. Please keep in mind both tests must be run to determine if a delay is periodic or not. Results are stored in comma-delimited files which may be imported into most spreadsheets. It is recommended that the results be imported and graphs created and studied. Again, differences of .06 seconds or less are NOT significant! Now a little CYA: NO WARRANTY IS EXPRESSED OR IMPLIED. THE ACCURACY OF THESES TESTS ARE NOT, IN ANY WAY, GUARANTEED. Brooks Clark 73524,363 It's Magic! PC Potions (303) 933-3531
