Keywords: Adaptec 2072 Controller Seagate 277 Hard-disk Disk Message-ID: <1884@van-bc.UUCP> Date: 19 Sep 88 11:41:54 GMT Organization: Balliffe Consulting, Vancouver, B.C., Canada Lines: 24 Would anyone like to share their experience in using the Adaptec ACB-2072 controller with a Seagate ST-277 (60 Meg, RLL) disk? If you have something to say about this setup, I would like to hear from you. I have found that the Adaptec controller only gives 25 sectors per track instead of the usual 26. Is there any way around this? There is a set "high-performance jumpers" on the board, but the only documentation I got with it, the ACB-2072 Installation Guide, doesn't give a lot of details on what they do. Is more detailed documentation on this controller available from Adaptec? On the ST-277, the one-sector-per-track saving could come out to about 2.5 Meg, which would be enough to hold another day of news for a full-feed. Please reply by e-mail if possible, if I get any informative replies, I will post a summary later. If you do post a reply, please also e-mail me a copy of it, as net.black-holes do exist and I am sure we won't receive every article. (I do read these newsgroups myself.) Thanks in advance. ...Sam -- Samuel Lam {alberta,watmath,uw-beaver,ubc-vision}!ubc-cs!van-bc!skl
