Using old iMac internal hard drive as external USB drive in new iMac
Hello,
My old iMac stopped displaying video, was out of warranty so I bought a new iMac. I salvaged the old hard drive from my old iMac, bought a SATA to USB adapter and hooked it up to my new iMac.
I thought it would be a simple drag and drop of my old files but when the drive is plugged in I get the following message.
I can see the drive in disk utility but it's not in Finder or anywhere else.
Hoping someone can assist.
Thanks!
iMac (21.5-inch, Late 2013), OS X Yosemite (10.10.2)
