Clive, glad you received the manual OK.

If you plan on removing the Hard drive from the Sony to the PC a lot – do as jwillis84 stated and get a SATA to eSATA cable as you don’t want to connect/disconnect the Sony internal SATA cable too many times. Also get a HDD power extension cable to avoid unnecessary wear and tear on the Sony internal HDD power cable.

As to bricking the Sony by hitting the wrong remote keys, yes it can happen. Really the same thing as changing any settings you don’t understand via the service menu in any modern LCD TV. People are always warned about entering the service menu in the LCD TV sub forum yet every once in a while someone reports hitting the wrong setting for their firmware version and zap – bricked LCD TV it is. Get the service remote just be careful.

As to DL burning - the way I understand it the laser has to penetrate through the top layer to the underneath layer at a weird angle to avoid burning the top layer. That is why so much extra laser power is needed as I understand it.

I think a good approach would be an Orico combo, trayless eSATA and USB3.0 dock, combined with a sata to esata changer and cable.

You need the changer to plug into the default recorders female eSATA connector and bring out the male pins.

Then the female sata to bring out a standard eSata connector to the dock.

The horizontal "dock" has both an eSATA and USB 3.0 connector, Do Not connect them both to the recorder and the PC at the same time!

But you should be able to attach the recorder hard drive into the dock, eSATA to the eSATA cable to the interior of the recorder and run that way. The recorder should boot and behave normally.

I've used this exact changer and sata to eSATA cable to bring out a connection from an AverMedia EZ310 and plugged that into an Orico dual drive external housing, and it works fine, that recorder boots and records or plays back fine.. but its a game capture recorder.. but this is much simpler.

The dock is self powered and really doesn't need the power from the recorder to power up the hard drive. It (only) needs the "balanced" SATA serial signal cables from the 7 pin connector. eSATA does not carry power so there is no danger of ground loop interference.

By removing the drive from the recorder, it lowers power supply draw on the existing recorders power supply, and removes the "heat" the original hard drive generated while inside the recorder. The hard drive also runs cooler itself because it is relocated outside the recorder.

The USB 3.0 port is especially "nice" because you can then schedule a "recorder to PC" dumping party.. and power down then unplug the recorder from its AC power, connect the PC via the USB 3.0 high speed connection and copy recordings off very fast. (So minimal wear and tear unplugging and re-plugging the SATA drive or SATA/eSATA connectors - but if you do, eSATA and USB are much more durable).

The hardest part might be removing the drive from its carrier since the screw threads are sometimes sealed with lock-tite.

I don't really like "vertical" docks because they tend to get knocked over, teeter over or have a hard time "fitting" next to a recorder on a shelf. Your forever pulling upwards at an angle making it more likely to knock it sideways or front to back.

The downside (there's always a downside) is having to manage a separate power supply for the dock. If you forget to turn it on, or a power surge takes out the docks power supply.. it will have to be turned on first (before the recorder) or you will have to get a replacement so you can power the hard drive on before the recorder will work. -- That would be a good reason for getting some sort of power supply extension cable and diverting power from the inside to the outside.

This is all speculative and probably more than the average person would seriously pursue.. but its fun to dream up Rube Goldberg contraptions isn't it?

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.

Thats very good advice, and will be ultra careful with the remote. Useful to have if the HDD should fail in this unit too.
Great advice and help all round here- I am very grateful
