Unfortunatly, the way SSDs work is veryВ different from HDDs that most traditional tools struggle to help at all. However, if you attempt to use these tools on an SSD, youвЂ™ll most likely find they arenвЂ™t quite so helpful. They all claim to be more effective than Disk Utility, but how well they do is very dependent on whatever is at the root of the problem.

If you have any disk management tools, like TechTool Pro, Disk Warrior or Drive Genius, you may able to try them out. Once you have an external drive, you can then use that as your boot drive, and recover any lost files to there.

So if you manage to resurrect your sickly drive, quit all your software, including email, to avoid overwriting any list files. If you have lost any data, it is very important to avoid using the drive, as anything that writes files to the drive, may be writing over your lost files. You should plan to get an external drive plugged in as soon as you can, so that you can secure your data there. If Disk Utility manages to fix your drive enough to let you boot from it again, be very careful how you use it. One thing to bear in mind is that if you do manage to boot from Recovery, youвЂ™ll need another drive to recover files to. If you manage to get in to Recovery mode, you should be able to run Disk Utility as described above, and potentially fix your disk so you can recover the data. Keep holding those keys until you see either an Apple logo or a spinning globe. In short, to enter Recovery you need to hold down Command+R while your Mac starts up. Booting from this partition doesnвЂ™t do anything to the main drive, so thereвЂ™s no need to worry about overwriting documents. This is actually a partition on the drive that contains a version of the macOS that you can boot from. However, asВ long as the drive failure isnвЂ™t too terminal, a restart in Recovery HD should be possible.
