Does the original Macbook Pro see the HDD still? could be a defective adaptor?
It is possible that the USB port doesn't provide enough power to run the drive. I doubt it but you may want to try a powered adapter. Alternatively, boot into Linux from a USB drive and see if it recognizes the drive.Hi,
So I took out my old Macbook Pro HDD out, and used one of these sata usb adaptors and the computer says the disk inserted is not readable by this computer. diskwarrior doesn't even see the drive. What options do I have?

Did you have File Vault on?
