And remember IBM's solution? Since they realized they weren't going to be able to replace them all before they crashed, they wanted to catch the ones that were in imminent danger of failure. So they added microcode to detect uneven rotation. The joke was that it also turned the drive into a seismograph. If you got a particular error code (I'm not sure I remember what it was, but 9F9F seems to be stuck in my head), you needed to either get the drive fixed ASAP or start earthquake evacuation procedures. -- Matt Simpson <mailto:[EMAIL PROTECTED]> 630 South Broadway -- (859) 257-2243 University Of Kentucky, Lexington, KY 40506 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
