Hello to all, I hope you are having a good day. About a week ago my iMac would not boot up. So I took to the internet to figure out what the problem might be and came across some useful information. I can boot up to Disk Utility and I see the hard drive and the space it has and everything but once I start running First Aid it tells me this: Repairing file system. Checking Journaled “” volume.Checking extents overflow file.Checking catalog file.Invalid key lengthThe Volume “*” could not be verified completely.File system check exit code is 8.Updating boot support partitions for the volume as required .File system verify or repair failed. Operation failed. If i run it again, it bugs out and says there is no space on the hard drive. In the Info tab it says it can be Verified and Repaired but i have no idea how. I have tried /sbin/fsck -fy in single user boot but it says that it cant do anything. I restored it to the external hard drive I was going to use to back it up but it shows the same thing when i run First Aid. So my questions are: Is It Fixable?Is there any way I can fix this problem without losing all the data stored on the HD?If not how can I recover all the data before I fix it?
You’ll need to boot up under an external bootable drive to fix your drive. I would recommend you make a full backup using TimeMachine so you can properly fix your drive. Sadly it will need to be reformatted and a fresh OS install (MacOS & Windows) to fix this as the boot sectors are damaged. Often times I see this with BootCamp installations when a Windows virus attacks the drives boot sectors. I would strongly recommend you get a good antivirus app that runs under MacOS & Windows as well. Here’s how to create the needed boot drive: How to create a bootable macOS Sierra installer drive Go to your Apps Store app and open the Purchase tab to locate your OS to re-down load it.
