I recently posted about my misadventures with the Mitsubishi MR535 drive in RLL mode and the 1024-cylinder limit. I seem to have mostly generated controversy on whether an odd number of heads is possible... So I'm going to ask again: I have a Western Digital WD1002A-27X RLL controller. This is an 8-bit XT controller running in an XT. I have no docs for it. I have been told that some WD controllers can disable the 26-to-17 sector remapping. Can this one do that? What are the pitfalls of doing so? Will I be required to run Disk Manager on all my drives? Or, can I get a BIOS upgrade which will allow disabling the remapping? Or, should I get another controller? -- --- James W.

You most certainly can do this. I have that controller, running in non- translation mode, in an XT. There is one jumper to move, I just don't remember which one it was. You can get a manual just by calling WD at (800) 832-8176 and asking for it. That's how I got my manual (which I promptly lost, or I'd look up the jumper for you!). The pitfalls would be that some BIOSs and/or DOSs don't like 26 sector disks. I don't know why this is, but if it works on your machine (it does on mine) you should be OK. >Will I be required to run Disk Manager on all my drives? You should only need to run DM on the drives that need it (i.e. >32MB) ----------------------------------------------------- Gordon S. Hlavenka cgordon@vpnet.chi.il.us Disclaimer: Yeah, I said it.
