You must be using Disk Utility in your system to perform disk management tasks. Repair Damaged APFS or HFS Partition by Using Disk Utility The next section describes how to fix an APFS or HFS+ partition.ġ. If your APFS or HFS partition is not functioning properly due to aging or usage, repair the partition immediately to avoid data loss. Many users, these days, are upgrading their macOS and moving to APFS to be on par with the current technology. In case your Mac is running on macOS Sierra or OS X Lion, the internal drive partition may be in the HFS+ format. And it may depend on using the optional RAID software OWC wasn't forthcoming regarding that potential issue.If you are using macOS Monterey, Big Sur, Catalina, or Mojave, then most likely, your internal storage drive is partitioned in APFS format. According to OWC tech support, only its dual Mercury Elite Pro enclosure is compatible. My OWC Mercury Elite Pro enclosures do not support full S.M.A.R.T. I'm not using any Samsung software with either SSD. My wife's 2011 13" MacBook Pro (High Sierra) has an internal Samsung 850 EVO. The internal Apple SSD is fully compatible. But a bug requires unplugging/plugging it in for the data to appear. My Samsung T3 USB 3 external SSD plugged into a 2018 Mac Mini (Mojave) provides full S.M.A.R.T. There is a free demo so you can test its compatibility with your drives. I do not know of any free utility that provides Drive DX functionality. Thanks again.ĭriveDX currently costs $19.99 for a personal license, which is a steal as far as I am concerned. It is an SSD I put in place of the original HDD, if that matters. Is there a decent free equivalent to DriveDX ?Īlso, I note that my system SSD drive is "S.M.A.R.T. That might mean the only tools that will work on them would be Apple’s own. But I have read that starting in Big Sur, Time Machine will be able to use APFS for faster and more compact/efficient backups. This is supposedly because Apple has not provided enough documentation for APFS.ĭiskWarrior can still help with current Time Machine volumes because they are still based on HFS+. I have kept DiskWarrior updated all these years (not cheap) but it is increasingly difficult to justify the cost because on new Macs booting into APFS, DiskWarrior can’t do everything it once could. When we move to Apple Silicon I wonder if Samsung will ever bother to let us fix their drives on Macs again.īack to on topic, when a Time Machine backup fails built-in verification, I have usually had success fixing them with hdutil (or was it diskutil) or DiskWarrior. Samsung only got away with that because Macs use Intel CPUs and could therefore boot up that way. Anyway, you used the command line to run the utility. ![]() It rebooted into MS-DOS or some form of Unix, I can’t remember. I had to update the firmware on my 840 EVO, and while they had a downloadable Mac fix for it on their website, the way this “Mac” fix worked was: Use a third-party method to create a bootable CD or USB stick and put the fix software on it, and reboot into it. I don't know whether Samsung was too lazy to write a Mac version of "Magician" But if your file system is corrupt, that does not necessarily mean that the drive hardware is going bad.Įxactly right, which is why I suggested using a utility like DriveDX to monitor the mechanical fitness of drive and to have the ability to replace it before it fails (with the possible loss of data). status may warn you about, in advance), you will lose non-backed-up data. If your drive fails (something that S.M.A.R.T. Disk First Aid is concerned with monitoring and repairing file system corruption and permissions settings. data is concerned with monitoring the health of the hardware. Of course, the drive/enclosure must be S.M.A.R.T. ![]() data provides a more comprehensive snapshot of drive health than Disk First Aid. So that's great, thanks for the suggestions.Ī utility that uses S.M.A.R.T. First Aid gives a clean bill of health, though it does take a while to do so. First Aid in Safe Mode did no good, Onyx seems to work only on the system disk, so I've erased the TM volume and re-set TM to the same place.
