Time Machine, 2 computers, 2 osx, files invisible
La Cie external 2 TB drive used with Time Machine to backup two computers, iMac 10.7 and MacBook Air, 10.9. Went OK.
On each machine, when the La Cie is mounted, the files for the other machine are not visible. For example, when the La Cie drive is attached to the MacBook Air, the Time Machine files for the iMac are not listed or visible.
Is this normal?
If the iMac fails and I want to access the files from the MacBook Air, how would I find them if they are not visible?
Is there a better way to back up files with mulitple computers and operating systems?
iMac, Mac OS X (10.7)
