(yes I am sure the original comment was to see if > we were all awake :-) but it's a good point). I did once see someone wipe a disk clean, by doing continuous read/write/read cycles on it. The first disk went in 3 months, then three months later the second disk (and the programmer, by the way) went. So I think it can happen, but probably not with the kinda load we see. ----------------------------+----------------------------------------------- Chuck Robey | Interests include any kind of voice or data chuckr@eng.umd.edu | communications topic, C programming, and Unix. 7608 Topton St. | New Carrollton, MD 20784 | I run Journey2 (Freebsd 2.0) and n3lxx (301) 459-2316 | (FreeBSD 1.1.5.1) and am I happy! ----------------------------+-----------------------------------------------
