HD6-SU3S2, NCQ

Postby WILLARD » June 7th, 2015, 4:19 pm

Why will NCQ not work on a drive in an HD6-SU3S2 enclosure that is connected to an eSATA port? The drive has been installed as an internal drive, and NCQ has worked. Native Command Queuing has also worked when the drive was connected to an external power supply and to an eSATA port by a SATA to eSATA cable. The combination of NCQ and a 64 MB write cache seems to almost eliminate file fragmentation. Lack of NCQ seems to result in increased fragmentation of files, and defragging of a 2 TB drive is a pain. I'd like to get NCQ working so I can continue using the enclosure. If NCQ was working, the enclosure would be just about perfect, but without NCQ the enclosure is of very little use to me.

Which eSata card are you using?
you sure your eSata card / port support NCQ?

This is the eSata card we recommend http://www.amazon.com/Syba-Controller-S ... ds=sil3132

I'm using the eSATA port built in to my main board. NCQ works when I connect a drive to a power supply and then connect to the eSATA port with a SATA/eSATA cable, but NCQ won't work on any drive that's installed in my Mediasonic enclosure.

This enclosure uses Prolific PL2773 chipset

looks like they don't mention NCQ, So their chipset doesn't have NCQ support
