I installed a new pump (ViaAqua 1300) into my system with a whole new tower setup. Has run for about 4 days with no problems. I boot it up last night and windows (xp) loads EXTREMELY slow. When I click on icons, I wait approximately 90 seconds for a response. My hard drive (20G maxtor 7200rpm) is partitioned, one 4G for OS and other 16G for games (I don't like to lose my downloads and games if I ever crash the OS). Now, when I try to go into the D drive (16G for games) I get the error: D: incorrect parameter. Nothing will recognize my D drive, it is like it is gone! I updated virus definitions (norton) and scanned the c drive-nothing (will not recognize d drive). I have restored the system to previous times, long ago, doesn't help and gives the error that D drive is either disconnected or something and will not be affected by the restore. I did a disk scan on C (d not recognized)-no problems. Uninstalled and reinstalled the driver for it-nada. The pump is about 6 inches above the hard drive, separated by a sheet metal shelf and the floppy drive in between. I even switched IDE cables. Now when I try to go into the hard drive windows tells me that the drive is not formatted would I like to format it now? What the heck is going on? Could the magnetic field generated by the pump be causing hard drive problems? I thought I saw a thread on that before but did a search with nothing except for the monitor.
