Hierarchical File System or HFS for short is a file system that is used in Mac systems. A file system is a format that describes how the folders and files are to be placed on the disk. HFS file systems work on smaller hard disks, so in order to accommodate disks of over 100GB in size, HFS+ and HFS Extended file systems were introduced.
Whether you have HFS, HFS+ or any other file system on a regular HDD or an SSD, they are all subject to corruption issues at some point or another. Corruption in HFS file systems can occur due to various reasons such as
- Sudden system termination during a read or write process
- Some third-party disk management tools if used incorrectly can cause damage to file systems
- Pulling out external storage devices without first safely ejecting the device
- Formatting the hard drive incorrectly
If your Mac HFS solid state drive is damaged and you’re looking for ways to repair these drives, you are in the right place. Here, we are going to provide some simple and effective solutions to resolve your Mac HFS SSD drives.
- Repair your SSD using Disk Utility
If you’re a Mac user, you are most likely familiar with the very common Disk Utility feature. This tool is capable of identifying and repairing corruption issues in your SSD’s using its First Aid feature. To repair and HFS SSD drive using Disk Utility, follow the steps below.
- Go to the Applications folder on your Finder and select Utilities
- Then select Disk Utility
- From the left side menu, select the SSD drive you would like to repair
- Click First Aid
Wait until the First Aid process is complete. The process will check the disk for errors and will repair them if it finds any. If Disk Utility is able to repair all the errors, then you should be able to access all files on the disk. However, if Disk Utility isn’t able to repair your disk, then you can proceed to the next troubleshooting step.
- Run FSCK
If Disk Utility fails to repair your SSD, then you may want to try running one of the big guns like FSCK, which stands for File System Consistency Check. It is run using the command-line, but that aspect shouldn’t keep you from using this tool. Just follow the instructions and you should be able to run this tool easily.
- Click Applications > Utilities > Terminal
- Type the following command,
This will show you a list of all connected drives, note down the disk # of the disk you want to repair. Once you know have the details of the disk you want to repair, you are ready to run FSCK.
To run FSCK, you will need to enter the Single User Mode, which is an only text super user mode for your Mac.
- Turn OFF your Mac
- Then, turn it ON while holding Command + S keys
- This will land you on a page with black background and white text
- Type the following command
‘/ sbin/ fsck – fy’ and hit Enter
Wait for the process to complete. If you see a message ‘The file system was modified’, run the tool again till you see a ‘The volume appears to be Ok’ message. Once that’s done, type ‘reboot’ to exit single user mode and boot normally.
