Having a good data recovery utility is critical.ĭata Rescue and FileSalvage both operate similarly, scanning your hard drive for recoverable data then retrieving this data in a second pass. Sadly, most people become religious about backups only after the first catastrophic loss of data has occurred. If you’ve already run DiskWarrior or Apple Disk Utility on a drive and you still can’t copy some files, try using Carbon Copy Cloner or SuperDuper! These tools can utilize several different methods of copying, and if errors persist will move on to other files without bombing out of the copy operation – unlike the Finder.Īccidents happen, and hard drives crash.

Having a bootable clone permits you to downgrade to your system to an earlier version if something goes wrong, or import data and applications as needed if you are doing a Manual Mac System Migration.Ĭloning utilities can also be useful in copying data which the Finder balks at, such as items with mixed permissions or disk errors. This program (as with others) can be loaded on a bootable USB Flash drive, a handy troubleshooting tool for Intel Macs when your full toolkit isn’t at hand.Ĭloning a hard drive is an essential part of backing up a system, particularly before doing an upgrade. TechTool Pro has been around for many years and is a reliable way to see what’s going on inside the case at the hardware level. This virtual stethoscope can test RAM, hard drives, graphics and other Mac subsystems, with detailed hardware tests and reports.
It’s important to use the correct version of DiskWarrior which supports your Mac model and operating system.Ī more complete alternative to the Apple HW Test Utility is TechTool Pro. I’ve found the best way to use this tool is to boot a troublesome Mac in FireWire target mode, then run DiskWarrior from a second Mac.

This works similarly to Rebuild the Desktop from the Classic Mac OS days but in a much more advanced way. Directory errors ( e.g., file not found), permissions problems, copy problems, systems which won’t boot (flashing question mark at startup), DiskWarrior is the thing I reach for first. My Go-To utility for disk related problems is DiskWarrior, hands down. Note that these discs are specific to the machines they shipped with, they will not work with other models. Restart with your restore disk in the optical drive – or Flash drive, for new MacBook Airs – and hold down the D key at startup to boot into the Apple HW Test Utility.
