You might no be able to see if the drive is RLL, but it is obviously possible. Not only does my ESIX figure the thing out, but so do many other MS-DOS programs like Speed-Stor, Nortons, and several other things. >Perhaps Usenet posters ought to be saying "ESIX requires no more than >17 sectors per track" (if that is true, which it probably is not, >because the disk off which I run ESIX has more than 17 sectors per >track) instead of blaming it on the recording format. > >Better, still, say something like "ESIX doesn't support my disk >controller, and it happens to use RLL recording, but the recording >format many or many not have something to do with it." When I talked to ESIX tech support when I bought ESIX, they said something on the order of this, "It's not that we don't support RLL. But rather that we have only tested it with the Western Digital 1006-SR2 RLL controller and we don't guarentee that anything else will work. We've heard that the Adaptec controller works but we have not tried it ourselves." The Perstor controller is strange (even by RLL terms). I have tried to steer clear of them since I have heard that they have compatability problems even under anything but plain MS-DOS. I don't usderstand all this talk about ESIX not supporting RLL. It does. Works great. -- David Kessner - david@kessner.denver.co.us | do { 1135 Fairfax, Denver CO 80220 (303) 377-1801 (p.m.) | . . . If you cant flame MS-DOS, who can you flame? | } while( jones);
