I changed my Hdd with an ssd using this guide. My hdd is now in a caddy where the optical drive used to be.
I can see my original drive ( Toshiba 500GB ) in the disk utility-app, but i can't reach my data on it.
When i take it out of the caddy again and put it in a external Hdd case, i can read it perfectly fine.
So there is nothing wrong with the hdd or the connection.
Is this a problem i can fix with software?
Thx for the help!
