When using a solid-state disk (SSD), it is recommended to use an operating system supporting the TRIM command to prevent performance degradation. I recommend reinstalling your operating system when moving to a new hard drive instead of using disk imaging, to ensure that ssd support is fully enabled.
- The installation media for your operating system. You may need to create recovery media if no disks shipped with your netbook.
- A T-6 Torx-style wrench. These have become very common at hardware stores.
- A new HDD or SSD.
- First, back up your files and settings to another computer or disk.
- Shut down the netbook.
- Unplug all attached devices and the power cable, and remove the battery
- Using the Torx wrench, remove the two Torx screws on the bottom of the netbook.
- Life the access panel from the screw side.
- Slide the hard drive off of its SATA connectors and then remove it.
- Slide the new disk into its place.
Put everything back together, install an operating system, and have fun. You may want to use the old hard drive as a portable hard drive using a dirt-cheap hard drive enclosure. These conveniently convert the disk’s SATA interface internally to a USB connection.
