SMART can report a certain number of developing problems with an internal hard drive that may be critical, but they won't get reported if they're on USB/FireWire drives. Unless 3rd party support is added, USB and Firewire drives will not be SMART capable. My guess is that if they made that list, they're good.Īnother word about external vs. Rather than provide a list re-hashing the merits of each I'd ask readers to refer to the list in the following link:Įveryone will have their own opinions on which one is best. NONE of the operating system tools will do scans for bad sectors on a hard drive. There can also be weak sectors which are readable by the drive but with great difficulty. When a hard drive detects a bad sector it's supposed to remap it to a spare sector if a spare sector is available. These will cross check index files on the drive and correct them as needed. Disk Utility will not detect bad sectors, nor will fsck. If you see that your hard drive is on its last breath and SMART technology has confirmed this, it's time to take measures to save your data.You cannot recover data from a bad sector. Open Disk Utility from / Applications / Utilities /, then click the disk and look at "SMART Status" in the lower left-hand corner. “Pred Fail” - this says your disk is damaged Right-click the Start menu, select Run from the provided list, type "cmd" and press Enter (you can also type "cmd" in the search bar to open the Run window).Īfter clicking OK, you will get a report showing one of two results: A hard drive health check in Windows can be done as follows: SMART will automatically notify you of data loss the drive can be replaced as long as it remains functional.ġ. SMART Status: examine your drive thoroughly Traditional hard disks are the most common. The higher a disks RPM, the faster its working speed. It keeps an eye on the disk's condition and delivers alerts when something goes wrong. Mac hard drives typically spin at rates of 5,400 to 7,200 RPM. On the hard disk, there is a tool called SMART for self-monitoring, analysis, and reporting. In other words, you must often examine the hard drive's condition for mistakes and damaged sectors. As a result, you should frequently check the condition of your hard disk so that you can be ready in case it fails. So, even if your drive is not subjected to extreme heat or physical harm, it will eventually fail. (Image credit: Microsoft) To do this on macOS, open the Disk Utility tool by going to Applications, then Utilities. This implies that even if the SSD is more durable, they will ultimately fail as well. Disk Utility, diskutil (FREE, comes with OS) Smartmon Tools (FREE, Open Source) SMARTReporter (4.95 for commercial version, but an older version is FREE) Scannerz Lite (21.95) Scannerz with Phoenix and FSE-Lite (39.95) Disk Tools Pro (79. SSDs don't have any moving components, but the cells get worse as you perform more write and read operations. Mac hard drive test software - creating the definitive list. A hard disk, after all, has moving components that may degrade over time, as well as magnetic sectors that may malfunction. Naturally, if you've been using your hard disk for a while, this could be standard. These may include clicking or screeching noises, sluggish computer performance, missing or damaged files, download errors, excessively poor data transfer speeds, etc. Your drive will frequently start sending you symptoms when anything is incorrect. Every hard disk has a shelf life and must eventually be replaced.
