INTERLEAVE SET..YOU MAY WANT TO ADJUST T HE SECTOR INTERLEAVE ON YOUR COPY DRIVE. PRESS I AND THEN ENTER THE SECTOR INTE RLEAVE YOU REQUIRE. THE DRIVE IN QUESTI ON WILL RETAIN THAT INTERLEAVE SETTING U NTIL YOU CHANGE THE SETTING TO SOME OTHE R VALUE OR RESET THE DRIVE. YOU WON'T B E ALLOWED TO SET THE INTERLEAVE TO A GRE ATER VALUE THAN 16, AS IT MAY MAKE YOUR DRIVE MALFUNCTION WITH POTENTIAL LOSS OF DATA AS A RESULT. IN ADDITION, THE INT ERLEAVE SHOULD NOT BE SET TO ZERO UNLESS YOUR DRIVE IS EQUIPPED WITH JIFFYDOS. THE INTERLEAVE SET FEATURE WILL ONLY BE AVAILABLE IF THE SERVANT IDENTIFIES YOUR DRIVE AS 1541 OR 1571 (IN ALL MODES)... WHAT IS SECTOR INTERLEAVE ANYWAY? WHEN DATA IS SAVED TO DISK IT IS ORGANIZED IN TRACKS AND SECTORS. THE TRACKS ARE LIK E CONCENTRIC RINGS ON THE DISK, AND EACH TRACK IS FURTHER DIVIDED INTO SUBSECTIO NS MUCH LIKE A PIE. THESE SUBSECTIONS A RE CALLED SECTORS. TO READ A SECTOR THE DISK DRIVE MUST MAKE SURE THE READ/WRIT E HEAD IS ON THE RIGHT TRACK, AND THEN W AIT FOR THE SECTOR TO COME AROUND TO THE HEAD'S POSITION WHERE IT CAN BE READ... THIS IS WHERE INTERLEAVE COMES IN. IF M ORE THAN ONE SECTOR ON A TRACK IS TO BE READ, WHICH IS MOST OFTEN THE CASE, IT I S NOT DESIRABLE TO HAVE THE SECTORS PLAC ED IN SUCCESSION. THE DRIVE NEEDS A SPL IT SECOND TO PROCESS THE DATA JUST READ AND SEND IT TO THE COMPUTER THROUGH THE SERIAL BUS. THEN THE NEXT SECTOR WILL H AVE PASSED THE READ/WRITE HEAD AND THE D RIVE WILL HAVE TO WAIT FOR NEARLY A WHOL E REVOLUTION. WHEN READING A LARGE AMOU NT OF DATA, A PROGRAM FOR EXAMPLE, THIS WAITING BECOMES QUITE NOTICEABLE. IT IS BETTER TO LEAVE SOME SPACE BETWEEN EACH SECTOR IN A SEQUENCE SO THAT THE NEXT S ECTOR IS JUST AHEAD OF THE READ/WRITE HE AD JUST WHEN THE DRIVE NEEDS IT. SINCE THE DATA HAS TO BE READ IN THE SAME ORDE R IT WAS WRITTEN, THE INTERLEAVE BETWEEN THE SECTORS WILL HAVE TO BE ESTABLISHED AS THE DATA IS WRITTEN TO THE DISK...TH E 1541 NORMALLY USES A INTERLEAVE SPACIN G OF 10 (READING EVERY TENTH SECTOR) WHI LE THE 1571 USES A INTERLEAVE OF 6. IF YOUR DRIVE(S) ARE EQUIPPED WITH JIFFYDOS , IT USES A CUSTOM INTERLEAVE SCHEME WHE N THE INTERLEAVE IS SET TO ZERO. PLEASE REFER TO YOUR JIFFYDOS MANUAL FOR DETAI LS. THE 1581 DON'T NEED SECTOR INTERLEA VE SINCE IT GOT ENOUGH INTERNAL MEMORY T O HOLD A WHOLE TRACK OF DATA AT THE SAME TIME...BUT WHY TINKER WITH THE SECTOR I NTERLEAVE? THE FASTER THE DRIVE, THE LE SS SECTORS HAS TO BE SKIPPED TO MAINTAIN MAXIMUM RELOAD SPEED. SO IF THE DATA I S TO BE READ USING ANOTHER DRIVE THAN TH E ONE USED FOR SAVING, OR IF IT IS TO BE RELOADED USING SOME KIND OF FAST LOAD, ADJUSTING THE INTERLEAVE WILL OFTEN IMPR OVE LOADING SPEED. FURTHERMORE, IF THE FILES YOU ARE GOING TO SAVE OR COPY ARE NOT PROGRAMS BUT DATA FOR SOME PROGRAM, THE PROGRAM'S ACCESS SPEED WILL OFTEN BE AFFECTED BY THE INTERLEAVE SETTING. EX PERIMENTATION IS THE ONLY WAY TO GET ULT IMATE PERFORMANCE BUT HERE ARE SOME SETT INGS WHICH CAN ACT AS A RULE OF THUMB:.. RELOAD DRIVE STOCK USING FASTLOA DER. 1541 10 6 . 1571 6 4-6.. THIS TABLE GOES FOR PROGRAM (PRG) FILES. FOR OTHER FILE TYPES THE IDEAL INTERLE AVE CAN ONLY BE FOUND BY EXPERIMENTATION . THE ABOVE VALUES MAY SERVE AS A START ING POINT, AND YOU CAN TRY TO INCREASE O R DECREASE THESE VALUES..
