I'm working on a Win2M machine, 400MHz, 138l megs RAM.
For some reason it won't see a new HD (80 megs), but putting it in another machine it's recognized and seen. I haven't a clue; ideas anyone?
Check these things:
Pins on the back: is it set to:
No Pins at all?
Check to see if the ribbon cable has been properly connected, make sure it is not upside down, if it is correct. try swapping it for another one
Check the BIOS. use the auto find HDD(hard disk drive) feature to see if it detects it. there could be a problem with the mobo itself(ive had this happen before. actually just recently one of my serial ports on my mobo burned out...no clue how) so it isnt detecting it (when doing the auto-detect, check to see if it even finds the landing zone, if its all blank, then something isnt plugged in correctly, but if it gets a landing zone, then it see's somthing but it just doesnt know what it is)
More often than not its a bios thing that you need to check, sometimes you forget to set it to autodetect, and its set to not installed so it doesnt look for anything (very common mistake)
