This will be a long explanation...please bear with me. I have 6 hard drives that I have data on. They are all Maxtor and Western Digital IDE Drives. I never use them all at once. One is my boot 20GB drive with Windows XP Pro. That stays put. The others I use as slaves. 80GB Maxtor on Master 2nd Channel with my TDK VeloCD Burner as the slave. 30GB Maxtor on Master 1st Channel on IDE Card with 13GB Western Digital as slave. I am running Athlon 750 on a Soyo K7VIA. 384 MB Ram, 32 MB All in Wonder, Actiontec 1394 FireWire Card, Adaptec ULTRA 100 Controller Card, and Adaptec SCSI card. Here is the problem. Last night my computer locked up. I left it alone and came back later thinking it would be done doing what it was doing. I waited about 20 minutes. When I came back it was still frozen. I decided to restart the machine. I clicked CTRL-ALT-DEL and clicked reboot. Went away for another 10 minutes and nothing. It was at this point I pushed the reset button on the case. Problem! When the computer rebooted the IDE card was not recognized as usual by the BIOS. I let the computer fully boot and then restarted it. Still not recognized. I then shut the machine down and unhooked the drives from the machine and rebooted. Everything was fine. I shut down and put the 30GB Master on the IDE card and rebooted. Still not recognized. I then shut down again and moved the 30GB Master to the Slave position of the 20 GB Wester Digital Master on the 1st IDE Channel. The computer booted fine. When it started the computer let me know that it had just found my 30GB hard drive on the 1st Channel Slave. I wondered why it would tell me that? I attempt to open the drive from My Computer and it says that the drive (D is not formatted, would I like to format it now? HELL NO! Where did my info go? I went and immediately shut down the machine and places the drive back in its original place as the Master on the IDE card. At this point it was recognized by the BIOS and I once again attempted to access it. STILL NO DATA! What happened? How can I fix this? What is wrong? WHY WHY WHY? I am really frustrated. Thank you for any help or words of wisdom.
