When trying to create a USB flash boot drive from the Mountain Lion image (4.348GB) using 2 brand new SanDisk Extreme USB thumb drives (8GB & a 16GB) the process concludes with " Restore Failure" & "Could not restore - Invalid argument" as shown below:
After performing a verification of the partition I get this:
Verify and Repair volume “Mac OS X Install ESD”
Checking file systemChecking Journaled HFS Plus volume.
Invalid B-tree node size
The volume could not be verified completely.
Volume repair complete.Updating boot support partitions for the volume as required.Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files.
I have reformatted the disc as FAT and used a PC to run in through Defrag and Scandisk. No issues showing up on either tools, no bad sectors and the drive sizes are showing correctly.
Why do I get this error? Is the ML image faulty? Please help me out here.
Thanks & Regards,
