That is why you need the iSkysoft Data Recovery for Mac (or. 5 Key Points that Mac OS X El Capitan Has Changed from Yosemite. It is not booting, and from the sounds of it, I suspect that either there is a bad cluster in a crucial location on the hard drive, or else the entire hard drive is failing. Normally, on a Windows machine, I would run chkdsk to either fix the bad cluster or determine that it was time to buy a new hard drive. Unfortunately, Disk Utility does not scan for bad sectors when you do a 'Verify Disk' or 'Repair Disk' (probably a good idea not to do this by default, and there is no option - as in Windows - allowing it). Drive Genius (Google it) does have a scan option; there is a free option which, I believe, will allow you to check the disk but not make any necessary repairs. But personally, I wouldn't bother. A modern hard disk will automatically remap bad sectors and SMART will soon tell you if it becomes a problem. Hey there, Rodion! Mac systems have an excellent diagnostic tool incorporated into the OS X and it's called Disk Utility. I'd recommend you to take a look at this guide from our knowledge base that explains how to test an HDD for defects or issues on a Mac computer: Hope it helps you! Cheers, SuperSoph_WD Disk utility won't check for bad sectors. Example: I was using a USB 3 hard drive and checked it wit disk utiliy and disk warrior. None of them found any issues. Then I checked it with DriveDX (I eventually found this app that checks for bad sectors and SMART errors), it found the disk riddled with bad sectors. If I'm not wrong, SMART iin a disk and SMART apps just report bad sectors that have been detected and (reallocated), among many other mechanical disk features, but it doesn't check for bad sectors on the whole disk (such as chkdsk can do in Windows). That's why I'm looking for an app that checks all sectors. I found drivedx is one. Ableton live mac osx torrent. Thanks for your answer anyway. My Mac tends to pause every now then when preforming simple tasks such as right clicking, opening menus and typing (It actually just froze when I started typing this question.). I've read in a few places that this may be due to bad disk blocks, and that the best way to fix this is to format and overwrite the whole disk with zeroes. Obviously, this takes time and will destroy any data I have on the disk. Is there a way to check for bad blocks without formatting the drive, or even remap the disk to ignore those blocks (ultimately fixing it)? My Mac is pretty recent (Mac Mini late 2011), so I doubt it has anything to do with low memory or swappage. Best document and photo scanner for mac 2018. I'll answer the 'bad blocks' tack and you can ask a follow on question if you still have slowness and you have concluded that it's not simply bad blocks. (Bad blocks is almost never a slow issue - since the system can remap blocks so rapidly, that you'd need rafts and rafts of them to actually impair I/O. If you do have bad blocks, they can corrupt some of the data on the drive and a reinstall not only fixes that, it forces writes to detect more bad blocks - kind of a win/win situation). You need no extra tools to see the health of your drive. Open Disk Utility and select the physical drive itself (not the Macintosh HD or whatever the partition/volume is) and select info. If you record and watch the values under S.M.A.R.T. Status and see how they change over time, you can know pretty much anything that is detectable about storage degradation or partial failure. 'Please: if you can't name a product, can you describe its method of testing?' I can't blame him for not naming a tool.
