Transferring External USB Drive into an Internal MacPro possible without formatting?

[jonnyback]

I have an external external 500gb Seagate hard drive, that works fine as a USB external but I wanted to put it inside my MacPro, is this possible without any need to format, just plug and play?

Thank you,

Jonny

Yes, provided it is sata it should work fine. I did in about 5 minutes
