I had taken hardware optimizations for granted; this is a reminder that things can change over time. Having read here a while back that Linux is very demanding of hardware set me thinking. For the last six months I've had problems with Windows Scandisk completing. I suspected my hard drive was heading toward failure [before I was disabled I was a computer technician, and this IS one of the first signs of hard drive failure a user will see], and before I installed Linux Mandrake 7 I installed a new HDD. The Windows Scandisk problem remained. In trying to solve Linux WordPerfect vs. StarOffice installs corrupting X windows, and sound configuration failures it occured to me to remove my 15% overclocking and accelerated DIMM timing from my hardware. These things were OK and had worked well for a year and a half. Removing the overclocking solved the Scandisk problem. The DIMM timing changed nothing and was reset. Too bad this didn't fix my Linux problems. -Gary-
