MY PASSPORT FOR MAC USER MANUAL 57 Checking Drive Health The data files on your My Passport drive are important to you. The WD SmartWare software has several built-in diagnostic tools to help make sure that your drive is performing well. Run one of the following tests if you are concerned that your drive is not operating properly: Diagnostic Tool Quick S.M.A.R.T. Status Check Quick Drive Test Complete Drive Test Description S.M.A.R.T. is a failure-prediction function that continuously monitors key internal performance attributes of the drive. A detected increase in drive temperature, noise, or read/write errors, for example, can provide an indication that the drive might be approaching a serious failure condition. With advanced warning, you could take precautionary measures, like moving your data to another drive, before a failure occurs. The result of a quick S.M.A.R.T. status check is a pass or fail evaluation of the drive's condition. Your My Passport drive has a built-in Data Lifeguard diagnostic utility that tests the drive for error conditions. The quick drive test checks the drive for major performance problems. The result of a quick drive test is a pass or fail evaluation of the drive's condition. The most comprehensive drive diagnostic is the complete drive test. It methodically tests each and every sector for error conditions, and inserts bad-sector markers as required. The best time to run the drive diagnostics and status checks is on a regular basis, before you encounter any problems with your drive. And, because they are so fast, running the quick S.M.A.R.T. status check and the quick drive test provides a high level of assurance with minimal inconvenience. Run all three whenever you encounter disk error conditions when backing up or retrieving files. To run drive diagnostics and status checks: 1. On the Drive Settings screen (see Figure 13 on page 27), click Diagnostics to display the Diagnostics dialog: CHECKING DRIVE HEALTH - 43
