|Important - power to the HD (modified 0 times) ||Thunder|
|After an unbelievable amount of thrashing, a friend and I were able to get our HDs to work with the internal IDE. The problem? We connected the 5V power for the HD to the pins next to the IDE header, which are obviously there for that purpose. When we used a splicer and moved the power lines to the power supply harness, the drive worked great! We had both purchased a WSP and Toshiba 6.5GB 2.5" drive. The WSP couldn't autodetect the drives (mine saw it once out of maybe a hundred times.) The other guy bought an additional 1.5GB hard drive, and the WSP saw that maybe one in ten times, though an old 150MB 2.5" drive worked every time. We tried everything; flashing bioses, checking the IDE signals with scopes, when finally he noticed that the hard drive worked if he powered it from an external supply. This is hard to understand; those power pins seem to be low impedence back to the supply, and a filter cap didn't seem to help. But hell with it, the new configuration works great so I won't worry too much about understanding the old one. [I thought I had tried powering from an external supply, but I had plugged the supply into the power header on the motherboard so my HD was still powered through that stupid motherboard connector.]|
Another note for those doing the IDE hack: the 2 discrete resistors aren't pull-ups, they're series just like the resistor packs. It may be that the 1K value recommended previously is fine, but I dropped mine down to 50 ohms.
Good luck! Hope this sucker will be sitting on my big-screen tonight...
