This is a very good point. In my practice in many cases the bad IDE cable may cause a lot of troubles or hard identify problems even some very strange like successfully ftped files are different (!) - no any errors, warnings, nothing. I've ended up with rounded cables and do advise to replace flats as soon as someone complains about "weird thing". Here are cheap and good: http://www.svcompucycle.com/ata133.html Thanks, Igor -----Original Message----- From: Barkley Vowk [mailto:bvowk@3jane.math.ualberta.ca] Sent: Wednesday, July 31, 2002 10:10 AM To: Axel Simon Cc: freebsd-hardware@freebsd.org Subject: Re: Harddisk damage by driver? I've had the same problem before, I was using an IDE raid board, and found that the best approach is to order 20 of the shortest (that fit), highest quality cables you can afford and then try them until you find one that works. (granted, I didnt have disk failures, I just had odd read errors and resets, but you asked about cable problems). One thing to remember is to never crease or fold the cables, keep them as straight and uncrinkled as possible. I know that sounds like a load of crap, but if your even near my office I can demonstrate for you. ----------------------------------------------------------- Barkley C.
