Use 'Cable Select' mode to possibly fix a dead drive Storage Devices
I have a 200GB 7200RPM DiamondMax 10 Maxtor hard drive (Model 6L200R0) in an IDE-to-FireWire external enclosure (some generic one, model ME-320 IDE). This enclosure's status lights are green and red. Green for power and that everything appears "good," and red for read/write and if there is an error. The Maxtor HD one day caused the enclosure to have a solid red light upon powering it up (when this happened before, it was a faulty IDE cable, which has since been replaced), and the drive would not mount, nor would a utility see it. Other drives work in this enclosure.

The fix was simple enough. Naturally the hard drive was set to a "Master" device, as it is the only device on that IDE bus. I changed the jumper to "Cable Select" and voila, the red light went away and the hard drive mounted! The drive seems to be fine, no bad noises or anything, but I still promptly copied off the data to another drive because of paranoia.

[robg adds: I can't test this one myself, obviously, and it doesn't make much logical sense to me. But if it helps someone else...]

Use 'Cable Select' mode to possibly fix a dead drive

Did you try setting the drive back to Master mode (which should be the proper mode) to see whether the problem was poor contact of the cable and/or jumper?

If you did not, then the test is not conclusive.

I thought of that, and it's a good idea, but I was too lazy. I will try it tonight.

Auricchio,
Good ups! It was a bad connection with the jumper. I took out the jumper (to simulate a bad connection) and this put it in slave mode, and I got the exact same results (red light, which, I never mentioned before, blinks very quickly every ~5 seconds), then I put the jumper back in, but in Master mode and it works! So this hint should read "Reseat a jumper to fix a hard drive".

For what it's worth, I was having some problems with an external Firewire 400 drive I put together (both power and activity LEDs would be stuck on) where it would hang my system during a shutdown. I discovered that I had mis-jumper'ed it to be in cable select mode (doh!). Strangely it worked fine for quite some time in that configuration.

Most drives need to be "master" to work, but some IDE/firewire-bridges need CS or can handle both. I doubt that switching between both settings will fix anything, but it is a known problem that IDE-drives sometimes "freeze" in an unknown state. Normally a simple power cycle will fix that, but changing the setting might reset some drives also - or reset the bridge.
