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
Mac OS X Zip Expanding Utility
Firefox (and possibly other applications) may ask you what you want to do with .zip archives that you download from the Internet. If you want to expand them with Mac OS X (rather than StuffIt Expander), you may be unsure of which application actually does the job. You're looking for Archive Utility (in Leopard and later) or BOMArchiveHelper (in Tiger). In either case, the application is stored in Hard Drive/System/Library/Core Services/. Don't move it from there, though, or you'll confuse matters.
