I have a RLL hard drive which has more than 1024 cylinders. I've heard that there is a controller that uses special mapping so that I can map more heads and less cylinders. Could anybody tell me which controller can do this mapping ? Apparently my controller (OEM version of WD1006-SR2) cannot do this mapping function. If I mapped those extra cylinders to ghost heads, then will SpinRite or Norton Disk Doctor run flawlessly ? Thanks. Seokrim Choi schoi@rodan.acs.syr.edu -or- dosa@cat.syr.edu

I believe disk optimizers and fixers like DI or Mace Remedy/Unfrag will work, but the Spinrite manual mentions that controllers which fool the machine into thinking its got fewer sectors/more cylinders are incompatible with it (or the other way around..) 8-) We managed to trash the second partition on a 60 Meg Priam drive which used EDVR.SYS with Spinrite.... Be careful with it. -- ------------------------------------------------------------------------------- Iskandar Taib | The only thing worse than Peach ala Internet: NTAIB@AQUA.UCS.INDIANA.EDU | Frog is Frog ala Peach Bitnet: NTAIB@IUBACS ! -------------------------------------------------------------------------------

It's called "sector translation." > Could anybody tell me which controller can do this mapping ? The Adaptec 2372A or B (or C, now?) does it just fine. > Apparently my controller (OEM version of WD1006-SR2) cannot do > this mapping function. Right. > If I mapped those extra cylinders to ghost heads, then will SpinRite or > Norton Disk Doctor run flawlessly ? Dunno' anout SpinRite, but NDD is unaware of anything "strange" with the drive and works just fine. > Thanks.
