Early DS drives, including Shugart 850's suffered from excessive force when heads were loaded on the media, for read or write opration. The "tap tap" test showed that head force could indeed damage media. If you can take your drives out from the enclosure, see if the bottom head is fixed or is on a movable arm. If the latter, you have a "tri-compliant" design, which Shugart (and others) abandoned in favor of a bi-compliant design with the lower head fixed. It's also possible that the drive simply needs adjustment. And it also possible that you're using cheap media. Stick with Dysan, Maxell and Verbatim. Avoid private labels, Nashua, Memorex, etc. Philip Burton 101 Twin Dolphin Drive Fortune Systems Redwood City, CA 94065 (415) 595-8444 x 526 - - - {allegra decvax!decwrl!amd70 cbosgd harpo hpda ihnp4 sri-unix}!fortune!burton
