HDD buffer failed?

[No-One]

The other day I opened defraggler and noticed that my WD 2TB drive buffer as "Unsupported". I've got no idea if it has always shown this or if it's just a recent thing. I've never really paid that much attention. I was curious so I fired up HD Tune and it also shows a similar thing.

My other 1TB drive shows a buffer as normal. Is this anything to worry about and has anyone come across this before?

Checked on WD 3 and 6TB plus a Samsung 850 EVO and they all have a buffer value of n/a - I think you can ignore it

I will then. Thanks
