How to Test an External Hard Driveby Charles Poole
External hard drives are used for backing up data from computers or housing very large files. If the external hard drive has errors on it, then the data could become corrupted or even lost sporadically. Testing your hard drive is not very hard. You don't have to download any additional software for this test. Do it yourself with little hassle and just a few clicks of the mouse.
Plug your external hard drive into the computer.
Click "Start" and then click on the "Computer" icon.
Right-click on your external hard drive and select the "Properties" tab from the menu.
Go over to tools and click the "Check Now" button underneath the "Error-Checking" icon. Click the box under "Automatically fix file system errors" and the box next to "Scan for and attempt recovery of bad sectors."
Wait for the computer to scan your hard drive and test for any errors on the drive. The system will also automatically fix the errors on the external hard drive.
Plug your external hard drive into your Mac computer.
Click the "Finder" button on the lower left-hand side of the screen. Click on "Applications" and then go to the "Utilities" icon.
Click on "Disk Utility" and then click on your hard drive from the left-hand side of the screen.
Click the "Verify Disk" and click "Repair Disk" after the scan has completed to repair any errors.
Click "Verify Disk Permissions" and then click on "Repair Disk Permissions" after the scan has competed to repair the disk permissions.
