IDE Hard Disk Drives

80way IDE ribbon cable

If your Hard Drive is what is known as 'ATA33' type, then it is connected in exactly the same way as the CD-ROM.

If, however, you have an 'ATA66/100' type, then the connection procedure is still the same, but the ribbon cable must be a special '80way' kind. '80way ATA66/100' cables look similar to their 'ATA33' counterparts, but have 80 wires instead of 40. They often have colour-coded connectors as follows;

  • Blue connector - to Motherboard
  • Grey connector - to 'Slave' Device
  • Black connector - to 'Master' Device

Note that connector colours may vary depending on manufacturer.

In both cases, it is important to note that the Hard Drive IDE cable must be connected to the Primary IDE connector on the Motherboard if it is to be the main/only HDD in the PC.

S-ATA ribbon cable connector

S-ATA Hard Disk Drives

Alternatively, if your Hard Drive is a S-ATA type, then the connections will be quite different. S-ATA uses a much thinner ribbon cable. New S-ATA compatible motherboards will usually have some S-ATA ribbon cables supplied in the box, ready for use.

Use one of these to connect each S-ATA Hard Drive to the motherboard connector as instructed by the motherboard manual.
