#Partition failed couldnt unmount disk mac drivers
īe aware that some features will be disabled like wifi on some models, graphics drivers will be in a reduced mode - this is normal in safe mode. Ensure the login window says 'safe mode'. You could always boot into safe mode & try erasing it in there - that should disable a lot of 3rd party extensions.īoot into 'Safe mode' (hold shift after the chime until the spinning 'cog' appears). Now Im trying to turn it back to 1 drive, but it is not working. It's possible Time Machine is trying to reconnect to the disk - is Time Machine disabled? I partition my hard drive into 2 different drives. The 'sN' indicates a session, also called a partition. How did you try to unmount the parts separately? Etresoft made it to make troubleshooting easier. Post the output here if you need help with it. Ideally you want double or more for Time Machine because it tries to keep older copies for you.ĮtreCheck should list it if it is installed, possibly a launchd job called 'com.WD…' or com.westerndigital…' You will not fit very many backups on that disk when your Mac fills up. disk1 looks like it is about 500GB, your Macintosh Boot disk is 750GB. Western Digital & Toshiba HD and Mavericks Western digital released some updated drivers, but personally I don't trust them - an external disk should not require drivers on OS X. It could lead to disks being erased/ corrupted etc. There has been several massive threads on incompatibilities with WD software on 10.9…
Make sure you set the partition option to be 'GUID' (in the partition tab).Īre you using WD disk software on the Mac? Once unmounted it should be 'eraseable' in Disk Utility. That should remove time machine & ALI, since thay are both on 'disk1' (based on the info posted above this can change on reboot so check again & edit the command appropriately). You could use the command that was shown in that old post to force the unmount of disk1. Which disk do you want to unmount, time machine, ALI, or WD SmartWare?
