My macbook pro 2011 decided to act dumb so I am going to reformat it, but first I want to strip my files off of it. I took the hard drive out and plugged it into my PC where it recognizes the hard drive and is healthy, but doesn't have a mount drive letter and I can view the files to begin the transfer.
 


wasn't getting through with it :/ , what do you mean, having issues with the menu options? I can still try and look up more , give me a bit
 
i get stuck on assigning a letter... it says "no volume specified please select a volume and try again"... even though my disk management recognizes the hard drive it doesnt have a volume letter
 
They left out a step, I am adding it here with my name next to it.


1.restart machine with Windows 8.1
2.determine "EFI System" parition with the Disk Management utility
3.run command prompt as administrator
4.type diskpart

PCIBUSDRIVER type list disk , Identify the correct disk by the size and then replace the Disk 0 below with the appropriate number

5.type select disk 0 then select partition 2 then assign
6.open windows explorer windows+e
7.refresh if the drive is not showing F5
8.try to open drive by double clicking


Try elevation, create a shortcut on the desktop to cmd (Just type cmd) and save, then right click the shortcut and select run as administrator. Then try the commands listed in the article.
diskpart
list partition
select partition x:
assign letter=b
exit

(Where x: is the number of the partition listed by the list partition command and b is the driveletter you wish to assign to the EFI partition)

Now kill the File Explorer process and start it with administrative privileges:

taskkill /im explorer.exe /f
explorer.exe
 
ok that worked... problem now... the Disk 0 has 3 partitions 1st 200 mb EFI system , 2nd 465 gb Healthy primary , 3rd 620 mb healthy primary... now i just mounted that 1st part, but my files are on that 465 gb section if that makes sense>
 
then go into detail with the help command, its just typing partition now... Read the help files in diskpart by typing simple things like "Help, or List Help, or assign help and so on.. Your doing fine

restart explorer as stated and try normal Windows disk management now that the Drive is there.
 
ok i did... but i really dont know what to choose as I am very cautious about losing my files ... i need them im a Dj and all my music is on this damn macbook hard drive. and only reason im going through all this trouble is because I updated mac OS to mavericks like it told me too and now i cant log into my mac...
 
I understand your jitters and concerns, I wished I could do this for you but I cant, You may just look for that special local tech that understands partitions and care. I wouldn't blindly play with partitions on important things as well. Another route would be to install a hard drive in your mac, then mount the original in a usb case then use it on the mac. Were treading into undocumented processes with risk here.
