Clarify please. When you write 'it still didn't fit' were you referring to
connecting the drive's connector to the adapter's connector? If the 2.5"
drive came out of a notebook, highly likely, it _may_ be fitted with an
adapter that interfaces between the computer and the drive. These adapters
used to be really common but I don't know what is being done with newer
systems. Worth a look anyway.
