Cold swap refers to the process of installing, connecting, or disconnecting a hardware device that requires the computer to be turned off during installation. This is contrary to hot-swappable devices, which can be removed or added while the computer is still running. Cold-swappable devices include RAM sticks, hard drives, graphics cards, and PS2 mice and keyboards.
It is important to know which devices are hot-swappable and which are cold-swappable. Usually only USB devices are hot-swappable, with some exceptions for storage units, but in this case, not because of the hard disk, but because of the bay where it is installed and the motherboard configuration. Hard disks are cold-swappable and cannot be removed or added while the computer is running.
While cold-swappable devices are not as practical and flexible as hot-swappable devices, it is possible to make them hot-swappable by using an external adapter. However, this can complicate the process of booting from the hard disk. It is important to note that manufacturers do not advertise the cold-swappable feature since it is a limitation of the device.
FAQs
What is the difference between hot-swappable and cold-swappable devices?
Hot-swappable devices can be removed or added while the computer is still running, while cold-swappable devices require the computer to be turned off during installation.
Which devices are hot-swappable?
Usually only USB devices are hot-swappable, with some exceptions for storage units, but not because of the hard disk itself.
Can you make cold-swappable devices hot-swappable?
It is possible to make cold-swappable devices hot-swappable by using an external adapter, but this can complicate the process of booting from the device.
Conclusion
Cold swap is the process of installing, connecting, or disconnecting a hardware device while the computer is turned off. While not as flexible as hot-swappable devices, some cold-swappable devices such as hard disks can be made hot-swappable with the use of an external adapter. It is important to know which devices are hot-swappable and which are not to avoid any damage or complications to the computer system.
