I have just got myself a new hard drive and was about to throw away the smallest 20gb HDD, then wondered if it is possible to have 3 hard drives. I currently have 2 ide channels, 1 supports a DVD re-writer and CD-RW, the other is used for 2 HDDs. Could I simply get a IDE cable wih 3 connectors, or would I need some sort of IDE controller card.
The easiest way is to fit a pci ide card, however if your struggling for space an external hard drive may be of more benefit. Caddys are ten a penny today and you should be able to pick one up for less than £20. If you've got space but no spare power connectors, you can buy a power splitter (effectively gives you two power connectors from one) for about 50 pence.
Whatever the case, you can't add more than 2 devices to one ide channel.
