How to allocate a second hard drive?
Most motherboards provide support for two IDE channels, IDE1 – the primary channel, and IDE2 – the secondary channel. Some modern-day motherboards have an additional controller, enabling them to provide four IDE channels. The connectors can be used to connect to up to four ATA devices, a “master” drive and a “slave” drive on each channel. The ATA standard has evolved over the years, with current motherboards supporting the ATA/133 standard. ou’ll need to verify that your computer has enough power supply capacity to support a second hard drive. Computers are normally built with extra power capacity, implied by the presence of spare power connectors. If you’ve already added devices to the machine, perhaps to the extent of having used all the available power connectors, it may prove necessary to upgrade your power supply unit (PSU). Each IDE channel will use an IRQ and I/O address as well, consuming valuable system resources; a system using multiple IDE devices may need to be carefully pl
