RE: sata 2 and sata 3 not active after boot up on dell 9010
You're asking for trouble, and you could potentially fry the PC and/or the drive.
Besides, those SATA ports are probably disabled in BIOS setup. You can't just enable SATA ports without drives connected because you'll likely get a "drive not found" error every time you boot the PC when a drive isn't connected.
Why not just put the drive in an external enclosure will allow you to connect via USB when needed?
