![]() Instead of fumbling for your install DVD, or relying on the Recovery HD's limited functionality, the eDrive gives you quick access to Techtool Pro along with several handy Apple utilities. The eDrive is what you'll use to test, rebuild or defragment your main hard drive, but it is really helpful if your main startup disk goes missing. If your startup disk stops working, and you need another startup disk, Techtool Pro's eDrive steps in to help. Most drive problems, however, result from data being in the wrong place, and can be repaired using Techtool Pro's Volume Rebuild tool. Sadly, if something is physically wrong with the drive, it will need to be backed up and replaced, but the sooner this type of damage is detected, the fewer files - like cherished memories and important personal documents - will be lost. So, it's important to be able to test drives for problems and then repair them. Because data changes so frequently, it can sometimes get scrambled. Your Mac's hard drive, even if it is a Solid State Drive, is more likely to experience problems than any other component on your Mac. ![]() Simply launch Protogo, choose Protogo from the Mode menu, and use it to set up a diagnostic disk.
