After a lot of searching on the internet I have been unable to find a solution to my problem. There are many people having similar problems, but no solution seems to work for me.
I have a 2013 MacBook Pro and I have a Toshiba 2TB External drive which I have used for the past 5 or 6 months to keep copies of my iPhoto Library and my Time Machine backups on. Everything has been fine up until yesterday. I plugged the drive into the USB slot to find it no longer appeared on the desktop. I have tried everything I can think of to get this to work. Here is a rundown of the situation:-
I have tried both USB ports on the Macbook.
The drive doesn't appear in Disk Utility or System Profiler.
I have bought a new USB cable.
The drive has it's own power supply and lights up and makes regular noises when on.
I have connected it to a PC and managed to access the files using HFSExplorer, which leads me to believe the HDD is okay.
I can browse both partitions and extract files to my PC using HFSExplorer.
The drive shows up in Disk Manager on Windows and shows the partitions.
I have another external drive, my old MacBook HDD in a caddy, which works perfectly, so I don't think its the USB ports either.
This is what I get in Terminal:-
-laeO@ /Volumes total 24 drwxrwxrwt@ 4 root admin hidden 136 17 Oct 13:36 . com.apple.FinderInfo 32 0: group:everyone deny add_file,add_subdirectory,directory_inherit,only_inherit drwxr-xr-x 32 root wheel - 1156 17 Oct 12:18 .. -rw-r--r--@ 1 rebeccaholmes admin - 6148 7 Dec 2013 .DS_Store com.apple.FinderInfo 32 lrwxr-xr-x 1 root admin - 1 17 Oct 12:54 Macintosh HD -> /
It really is bizarre. I am left thinking my only solution is to go through the arduous process of copying all the files to my windows PC and reformatting the HDD :(
Does anyone have a better solution to this problem?
Edit - Since posting I have also tried resetting the MacBook PRAM and SMC. Neither has made any difference.
Edit - Using DiskUtiliy after entering "defaults write com.apple.DiskUtility DUDebugMenuEnabled 1" command lists no external drive.
"diskutil info disk1s2" returns the message "cannot find disk"
