I have 2 hard drives in my pc. Drive C has the operating system install on it and Drive D has my personal files on it. I disconnected Drive D as I think it's about to die but when I disconnect it and then turn the pc back on, Drive C is not being recognised.
I checked the bios settings and it wasn't coming up in that either. So now I have reconnected D drive and it's recognising them again.
How can I disconnect D drive without it affecting C drive with the OP installed on it?
These are 2 seperate hard drives, not 1 partitioned one.
The one i am trying to disconnect is an IDE cable and the one i want to keep connected with the operating system installed on it has a sata cable.
In bios they are both set to master.

Have you pulled the jumper from the SATA drive?

I worked it out. There were 2 different sata outlets on the motherboard for the cable to plug into, I just changed which one i plugged it into, restarted and the bios recognised the drive but thanks for answering.
