Just how long will your hard drive last? Cloud backup service Backblaze, which relies upon consumer-grade hard drives, performed a study of 25,000 hard drives over four years. The good news is that 74 percent of the drives survived four years. The drives had a 5.1 percent annual failure rate in the first 1.5 years, which dropped to 1.4 percent in the next 1.5 years, then spiked to 11.8 percent after that. Backblaze expects that over half the drives will last six years. Regardless, all drives die eventually, so backups are still a must. follow link
Untrash the Trash
Feeling trasher's remorse? On Snow Leopard, you can open the Trash (click the Trash icon in the Dock) and "untrash" individual items there. Select one or more trashed items (files and folders) and choose File > Put Back. This returns the items to where they were when you originally put them in the trash. The keyboard shortcut is Command-Delete - the same as the shortcut for trashing an item in the first place, since in deleting something from the trash you are untrashing it.
