issue resolved- see post #3 Hello, I have a damaged hard drive (WD 250GB) that I pulled from my external enclosure. I'm trying to do data recovery on it, so i connected it to the slave IDE cable (middle one right?). Now when I start up my PC, it gives me that error message, but my Primary boot disk (Seagate 80GB) works fine when th Slave isn't plugged in. (I'm guessing it's a BIOS or a jumper setting that's telling it to look at the Slave as the Boot disk???) I thought I had the BIOS configured correctly to the best of my ability, but now it's beyond me. Any help would be greatly appreciated.
