I want to remove Recovery (D:) to get more space. How do I do that?
HP does not recommend destroying the Recovery (D:) partition or the Recovery data. The fastest, most reliable method of recovering the computer is recovering from the hard drive. If the recovery partition is removed, the only method of recovery is from discs which are slower and can be scratched and damaged.
If you need more disk storage space, consider adding another hard drive - either internal or external. If this is not an option and you still want to remove the recovery partition, you can use the following steps to remove the Recovery (D:) drive:
Make sure that you have created a set of recovery discs! If you have not created a set of recovery discs, do so now. For more information about how to create a set of recovery discs, see Creating a Recovery Disc Set in Windows Vista.
