You should also see the name of the disk such as ‘Macintosh HD’. Be sure you backup your files to an external drive or second internal drive, the following procedure will remove everything from the hard drive!We are now going to force erase the physical disk, creating a single Mac OS Extended (Journaled) volume.I did, however, find another tool that was able to see the drive and its current file structure.The tool is called Test Disk 6.13 ( Disk_Download), which is an open source program for all variants of Operating Systems.Invalid key length Invalid record count Catalog file entry not found for extent The volume could not be verified completely. Updating boot support partitions for the volume as required. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
You may try formatting the drive in order to use it again but this will delete all data stores in it.
, and at this point I'd urge you to backup whatever thats in that drive that means to you.
IO errors are usually VERY bad and could indicate a hardware failure - anything from bad clusters (which arn't too bad), bad cables (which are annoying) right down to gradual, complete, irrecoverable failure.
I have found myself recently experiencing a couple of Macs which would not allow me to repair the directory or permissions in Disk Utility, or erase/partition the drive with an error such as: ‘Disc erase failed couldn’t unmount disc’ or ‘Disk Erase failed with the error: Couldn’t unmount disk.’ Even trying to use Network Deployment tools such as Apple’s Netinstall service or Deploy Studio have also failed to deploy due to these errors.
Normally, any ‘Couldn’t Unmount Disk’ error is attributed to circumstances where the boot drive is being modified or is being used by an application or process.
