I have a 500 gig Buffalo HD-PNTU3 external drive that I use for archived data. At this point the drive is used to access older files, nothing new has been written to it for a while. It's roughly at 80% capacity.

Recently it's been harder to access the data in the drive. Under the suspicion that the USB port or electronics may be failing, I removed the drive from the external case an put it into a generic external case. However when I try to access the drive, I see an intial set of activity, then nothing.

Now, it could very well be that the drive, a Seagate Momentus 5400.6 mechanical drive, may have failed, but I find this a bit hard to believe because the drive is rarely used and just sits in storage for the most part.

So before I write this drive, and data on it, off, I started wondering if perhaps Buffalo may have added it's own firmware to drive so it only works with it's interfacing electronics. Is this a possibility? If so, is there a way to bypass this so I can access the data on the drive?

Thanks for any info on this.
 
Solution
Install the drive directly to a PC.
The old enclosure was likely accessing the drive in 512bit/512bit emulation mode and newer enclosures use 4k mode.
Your PC should be able to access it in 512 if it's still working.
