No, Only if you remove and leave off receiver outer cover, Adapter sticks up about 1/2 inch to high. You need to cut the hole or run wires out back of receiver to drive outside receiver, some where. Even if you take the heat sinks off (I don't think they are need at all with a cool running drive) it still sticks up. There's just not enough room in receiver to fit converted drive in and put cover on.
If you could get a large capacity drive the size of a laptop drive hooked up to a adapter it probably would fit, but not a regular size drive.
Drive and Adapter will fit inside receiver, but you cannot snap the cover down in its OEM position.
-put drive inside, and make a spacer of somekind to hold receiver cover up 3/4 inch higher. (a wooden dowel or strip front to back on both sides) Would leave a space on both sides/front/back of same 3/4 inch. This would actually help with cooling receiver inside, put a fan on each side plugged into receivers USB jacks, air wood go in/out easily.
I've had adapted drive sitting inside receiver with no cover on it, drive sitting on shelf behind receiver,and my current removable drive bay sitting on top with wires going inside via a hole in cover (fortunately had a spare cover)
For my usage I like on top and with removable drive bay
Even if you do nothing else, get some fans sucking air out, and blowing air into receiver, I'm convinced heat is what kills these units. I've had "zero" lockups, reboots, or other troubles since changing drive an getting 3 fans blowing on receiver.
Someone else had converted USB drive by cutting and soldering wiring for it to get drive inside receiver with cover on as far as I know.
My way is a little bit more plug and play.
Its nice never having to delete any recordings, unless you want to!
