Installing a 3rd hard drive causes all IDE drives to not detect

I ran into a problem last week I couldn't figure out:

I currently have two PATA drives on IDE0 and a DVD burner on IDE1. I have an old 7200rpm, 60GB PATA I'd like to use for storage. So I put that 3rd hard drive in the case, set it to slave, ensured the DVD burner was set to master (w/ slave present), and plugged in the ATA33 ribbon cable (not a big deal if the drive is limited to ATA33) and power.

When I turned on the computer, at POST, there was 0 of the 4 IDE devices detected. I kept turning it off, reconnecting and making sure all jumpers were set right and that no plugs were loose, and trying again. It seemed weird because even if that 3rd 60gb drive I put in was hooked up wrong or anything, at the very most, anything on IDE1 would fail to detect but my two hard drives on IDE0 would detect normally.

After 15 minutes of trying all that, I unplugged the 60gb I just put in. I STILL had zero IDE devices detected at POST. Starting to worry now, I pulled out that 60gb hard drive, made sure the my original 3 devices were connected OK, and turned it on. Back to normal and everything detected fine.


So what would make that hard drive cause every other IDE device to not work? The only thing I could think of is that it was shorting to the case or something. Since I have almost no room for more drives in the internal 3.5 spaces, I placed that 60gb drive in the external 3.5 slot where the floppy drive would go. It still fit fine and screwed in like the internal slots. Plus I am 99% sure that when I had an old 27.3gb as a third hard drive for a while, it was placed in the external 3.5 slot like I put the 60gb in.

Any ideas?

I've seen jumper settings cause this kind of issue. I'm sure you are setting the jumpers correctly but when was the last time it worked? What if you make it the master instead of the slave? What if you make it master and just plug it in with no other IDE devices plugged in? Does it show up in the bios? Does the HD work in another computer still? Have you tried a different cable?

Ok, try this. Put the 3rd hard drive as the 2nd IDE Master and the optical drive as the slave, i have the same setup and it didnt work either unless the drive was the slave and the hdd as a master, or if you have the option on the drive, put the jumper on CS (Cable select) which basically sets it up on its own, I use CS for my 2nd rig with 3 hdds and 3 drives. It works perfect when all are on CS, but if one is set to master and one to slave, everything stops workin. If that doesnt work then id say try switchin up the hdd setup, like the 3rd hdd setup in place as the primary slave and where the 2nd hdd was, set it to the secondary slave.
