Update: On 31 May the culprit U4/G5795 sop 8 chip was finally received, immediately soldered onto the interface board and the USB to Sata adapter with my 2.5 ich SSD hdd tested. It worked perfectly and my friend was happy his device could be used like a new device again!

Well done, Albert.
The drive works and is seen again.
It's also accessible again, like it should.
Thank you...

Greets, Marco

PS: Today I tested even a marked 2N2369 without the A extension that still didn't work in my 2 build OSH Park board Jim Williams avalanche fast rise pulsers! And without those exact selected 2N2369 transistors that no longer are available, the OSH Park pcb circuit never will work! It did cost me a lot of invain ordered parts exact according to the given BOM part list. So better build another pulse generator as given on Hackaday or Kerry Wong's design that works with many different transistors! Even with the ones that completely failed in the OSH Park circuit!

Update: In case anyone also is planning to build the OSH Park avalanche fast rise pule giver, they do not work with the 2N2369A transistors. The transistor must be a now no longer sold or manufactured 2N2369 type. Apparently only with those the pulser works producing fast rise pulses in the kHz range! With the wrong 2N2369A types used they only avalanche at random at a very low about ~2Hz frequency and are completely useless to use to trigger your scope on for the purpose the Jim Williams Pulse generator was designed! Instead therefore better build Kerry Wong's avalanche pulser that probably also works with the 2N2369A transistors at a higher Uce breakdown supply voltage of 120V DC. See here for more info.

After my above mentioned just $5 USD costing PcbWay order became extremely overpriced on insane and wrong DHL import charges, after DHL already was paid $23USD for shipping costs, I refused the parcel and asked DHL and PcbWay what in-the-hell had happened?
DHL after 5 days answered that I could ask for a special form to state my complaint, but I gave up on DHL and PcbWay and in the meanwhile opened a dispute on Paypal and on Pcbway for a full refund. And today after many emails and bad communication I finally got my S30USD money back minus a small fee again to Paypal. So I hope never having to deal with money ripping DHL or PcbWay ever again!

I have the improved RT809H nand programmer that can do what the RT809F can do and more, Yogesh. Plus the Genius G540, The TL866/866II, The Xeltek SP-L programmer, and the new GQ-4x4. Plus the Elektor Gal programmer, several Eprom programmers and some other devices like a STM32 programmer. Plus a few USB to serial adapters, and a few self made USB programmers like the USBasp and others. And of course also some of the necessary USB to FPGA interface adapters for programming Xilinx, Altera (Now Intel) and Atmel (Now Microchip) FPGA and also AVR chips. And also a DIY Wireless Xilinx FPGA programming interface with a programmed Raspberry Pi 3B+ board that works in the Xilinx Web development version starting with the Vivado devices. (Interface is not supported to work in the older Xilinx FPGA development programs for Spartan and so on versions).

Albert,
Nice write up,
I think external SATA casing is more economical.Now future repair jobs becomes more complicated because each and every module in electronics are programmable.do you have RT809F Serial ISP BIOS Programmer?? ......just for review.
