#Diskwarrior for mac os x install

Is your new 1TB HD bootable? If so, just install DiskWarrior on that and use it to try and fix the external.Īnother solution is to install Mountain Lion on a USB flash drive and then install DiskWarrior and other utilities. Their solution has been to supply a bootable DVD with DiskWarrior on it but that DVD will not boot your MacBook Pro, which is what their message is telling you DW 4.4 does work on Mountain Lion, just not their DVD boot disk.Īs a general rule, it's a good idea to maintain a bootable backup of your HD and you could boot from that to fix your problematic external. Can someone please just tell me if it'll work on my computer? I need to get my files on my hard drive back asap.ĭiskWarrior needs to be run from a boot disk other than the one you're trying to fix. Other places I've seen it will only work up until OS X 10.7. However on their front page it does say that version 4.4 does work on Mountain Lion. I've found out that DiskWarrior 4.4 will do the trick however in their support page it says ' The current DiskWarrior DVD cannot start up the new MacBook Pros introduced June 11, 2012' which is what I have and I'm a bit sketchy about spending $100 on something that isn't even supported by my computer. I'm currently running OS X Mountain Lion 10.8.3.

About halfway through trying to transfer the files, I got a pop up saying 'The Disk you inserted was not readable by this computer.' even though it had been working fine. DiskWarrior, the worlds most advanced and highest rated hard disk, hard drive, and disk repair and data recovery tool for macOS, OS X and Mac OS X. Yesterday I plugged in my old WD 750gb external hard drive, trying to back it up on to my new 1tb hard drive.
