Couple of latent thoughts.
The SONY RDR-HXD995 (also) has a PICT bridge USB type B port, which is very similar to the USB 3.0 type B jack on the back of the "sled" style Orico trayless dock in the previously attached picture.
That could easily be permanently hi-jacked or "wired" with a bit of soldering or judicious rearrangement of the PICT bridge jack inside the recorder such that the entire Dock could be placed inside the recorder, and that PICT bridge port become the sole external access port for offloading the recorder hard drive contents.
There were never a lot of PICT bridge JPEG printers, and people using the recorder as a digital photo storage album hooked to a PICT bridge printer wasn't all that common.
You still need the dock power supply to power up the dock when the recorder is disconnected from AC.. but its a much smaller set of two wires for the wall adapter snaked out the back or in between the cover and the chassis.
Also, this would not interfere with the "Undocumented" keyboard feature that SONY inherited from Pioneer using the USB type A connector. (Entering recording Titles using a "real" full sized keyboard hooked up to a recorder is vastly easier than using the cell phone style keypad entry)
I rather like the "hi-hjack" method unless your regularly un-pairing and re-pairing drives with the service remote and treat them like VHS tapes.. which is probably unwise. Hi-jack literally gives you a USB type B port, with the "Blue" connector familiar to those who use USB 3.0 to access the internal hard drive. IsoBuster can then read the drive and offload the recordings in pretty much the manner most people said they wished they could way back in the early 2000's - the only sure fire addition, might be an optional Wiebetech "USB write-blocker"
CRU "Write-blockers" are normally used only by forensic investigators and can run for a lot of money brand new, but they show up used from time to time. They sit (in-line) between a USB drive and a PC and allow the PC to "think" it has read/write control over a drive, but simply "drops" Write commands to the drive by filtering them.
This would be the (ultimate) in safely connecting a recorder hard drive to a PC. Even if windows goes rogue or a user makes a mistake and allows windows to try to initialize or format the drive.. those write commands are automatically dropped, without denying windows access.. so windows "thinks" it succeeds in writing to the drive, but in reality the drive never suffers damage by the PC and remains safe and secure.
But seriously, this diverges quite a bit from the simplicity of temporarily removing the hard drive, putting it in a dock and reading it with IsoBuster. Then putting it back in the recorder.
Its very easy to (overthink) this situation entirely in the pursuit of aspirations that are just .. unrealistic.
