SharpIsland Posted March 21, 2014 Share Posted March 21, 2014 I have a few hard drives in this mac pro tower 10.9 Mavericks - they show up in Disk Utility but will not mount. DU shows a sort-of "blank document" or "unidentified filetype" image instead of the normal icon for external media. I used CCC to migrate data from a 3TB drive to a 4TB drive on a computer running a 10.8 Mountain Lion - and then (with the hard drives disconnected) upgraded that machine to 10.9 Mavericks. Since re-connecting, they will not mount. However, they will also no longer mount if I place them in a NAS connected to my MacBook Pro running 10.6 Snow Leopard. Both yes, are over 2.2 TB in size. They used to work before (and connected to each other via shared folders, etc, etc. /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *250.1 GB disk0 1: EFI EFI 209.7 MB disk0s1 2: Apple_HFS Sharp Island 249.7 GB disk0s2 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *3.0 TB disk1 1: EFI EFI 209.7 MB disk1s1 2: Apple_HFS Media 2 3.0 TB disk1s2 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *1.0 TB disk2 1: Windows_NTFS System Reserved 104.9 MB disk2s1 2: Windows_NTFS 1.0 TB disk2s2 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *7.9 GB disk3 1: DOS_FAT_32 OSX TOOLS 7.9 GB disk3s1 /dev/disk4 #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *7.9 GB disk4 1: Apple_HFS OSX 7.9 GB disk4s1 /dev/disk5 #: TYPE NAME SIZE IDENTIFIER 0: Apple_partition_scheme *1.5 TB disk5 1: Apple_partition_map 32.3 KB disk5s1 2: Apple_HFS Sharp Island 3 1.5 TB disk5s3 /dev/disk6 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *3.0 TB disk6 1: EFI EFI 209.7 MB disk6s1 2: Apple_HFS Media 3 3.0 TB disk6s2 disk0 is the System SSD - running smooth as butter. disk1 and disk 6 ("Medias") are the culprits. they will not mount and Disk Utility shows them as having "0 folders and 0 files" - although showing they're actual disk usage/capacity. disk 2 is a Windows installation (doubt its relevant though) disk 3 and 4 are USB sticks, and disk 5 is another drive equivalent to the "Medias" here you can see the icons for those partitions does not load, either .. Any help would be greatly appreciated! thank you! Link to comment Share on other sites More sharing options...
iFIRE Posted March 21, 2014 Share Posted March 21, 2014 try boot with the USBInstaller and go to UTILITIES/DiskUtility and REPAIR the disks that you have problem, or you can try from Maverick or ML the app Disk Warrior to repair it Good Luck!!!!

SharpIsland Posted March 21, 2014 Author Share Posted March 21, 2014 DiskWarrior said it fixed things, but nothing actually changed It "mounts" with 0 files and folders - but you can see that the files are taking up space. It doesn't every actually show up in Finder either. - DiskUtility says I can "unmount" it but it never popped up into the Devices list in Finder. This is rather weird Link to comment Share on other sites More sharing options...
iFIRE Posted March 21, 2014 Share Posted March 21, 2014 try copy a file from the disk with of terminal app cd /Volumes/Media 2 then a ls then copy any file to the desktop EDIT: more easy to you open diskutility and app Terminal now in terminal app type cd and pull the disk from disk utility to window of the Terminal, +enter ls and see if display yours files Link to comment Share on other sites More sharing options...
fantomas Posted March 21, 2014 Share Posted March 21, 2014 hi please read this! "If you have already upgraded to Mavericks and are experiencing difficulty in accessing your external hard drive, please do not save anything to the drive, disconnect the drive from your computer, and contact Western Digital Customer Service" 1 Link to comment Share on other sites More sharing options...
