I made sure the firmware is the same version. This is all listed on the drive itself.

@@Thesignalpath Firmware is only one bit of the story, service information and maps also stored on media.

Agree, the bad sectors are stored on the board for instance... swapping the EEPROM from the bad board to the good one is likely what is required.

@@xDevscom_EE Yup this, must admit I was a bit surprised it worked without errors. Got lucky.

Brian Frost , Funny you put it that way, too!

Ah, pardon, this is not FMR6, this is the more recent stuff with SATA interface, likely FMR7? I think 6 was the last one without SATA.

But can it run Doom?

At 15:11 BIOS says FMR7

@@benmodel5745 I'm pretty sure Doom would be a walk in the park, it's from the 486 era after all. Crysis is another matter.

I'm pretty sure Shariar will have the HDD image file saved using something like dd on his NAS, cloud storage or even a USB thumbdrive. There is no rush to SSD.

@@Drew-Dastardly LOL - Yep, but NOT done similar things myself and spent days and money getting images from suppliers that i didn't need to do if i had just done what i have said :( I always back up now at the first chance, as i do alot of CAD CAM machine repairs and it very easy to either loose, or delete the data :( :)

Yes you are right, the very first thing I did was to image the drive. :)

...but leave the poor outsourced power supply to suffer its own thermal agony :-)

Brendon Bentley pure german engineering, engineer everything brilliantly, ensure something breaks in time

@@sunnohh It is doubtful that the design intention was to ensure that something breaks in time. There are principally two risks with outsourcing any hardware block. Firstly is poor integration which usually results from misunderstanding the outsourced portion. This misunderstanding comes from poor documentation by the manufacturer of the outsourced block or expectations/assumptions by the integrator that deviate from reality. Secondly the manufacturer of the outsourced hardware may not put the same care and emphasis on quality (often driven by business level/company culture considerations) that the integrator expects. This is not always simple and easy to detect, verify, document & enforce. For these reasons it is seldom a good approach to outsource anything. If saving development time on an outsourced power supply is valuable, then go for it. But please do go back and do your own power supply at the end to be in control of your own product. Power supply failures account for most electronic failures and may even cause more damage down the line. Perhaps the hard drive in this video failed as a result of the power supply? (...because it is seldom to find two independent failure modes on a broken item.)

@@asm2750 I had the chance to select what kind of instrument I need for my job and I picked FSW85 (2Hz to 85GHz) spectrum analyzer, my former employer bought it. In the end I regretted my decision. The RF performance meets with it's price tag, but the GUI is buggy and can poorly operate with the connected RT2064 sampling scope.

Pooch was on his sabbatical this week! ;)

@@Thesignalpath , LOL!

Just do it in the shower to keep the dust down. :)

Just the THOUGHT of doing that makes spots on my little undershorts.

It isn't that bad as long as you do it in a reasonably clean environment and clone it sofort (i.e. with Germanic immediacy).

I've done it twice in my life and it has worked, in a non clean room environment. If it's your last resort, either the controller or motor and you need that data.

@F. BERTAGNE A good data recovery company is the right way to go if you have things you might not want to risk losing, but like you said, not cheap. Thanks!

Same request here

I made sure to get an identical HDD with the same firmware revision. This is listed on the HDD itself which is great.

@@Thesignalpath Not just the firmware is important, specific drive parameters (e.g. bad tracks, alignment info) are also stored in most drives. Therefore one should exchange the chip, although just for reading it make work for a while.

Yes it does.

I'll try to do a teardown. It is a really nice instrument.

Interesting!

No I don't actually have one of those in the lab. Looks interesting. You can always ping R&S that you'd like to see a review on my site for the instrument. :)

At this point the Siglent will give you a lot more features and much better user interface. I’d go with Siglent.

Sure, it is on my list.

@@Thesignalpath Thanks alot Shahriar. I'm wondering what actual instantaneous dynamic range for current measurement is possible... ie. if an IoT device is deep sleeping in the nA's and wakes to pull 100's of mA's... will the unit support/log this fast dynamic auto(?) ranging and provide accurate capacity estimates of what the DUT is demanding. Are there hi-speed switched/banked shunt resistors(?)... etc.

Yes, they are Ikea. But discontinued. :(

@@Thesignalpath Typical - they usually discontinue anything worth making or they change it to a lower standard. Great idea nonetheless. When I saw them used this way I immediately thought they must be using the same mechanism as that inside shower a curtain rod. I've been racking my brain for years (pun intended) on what the ultimate solution for an adjustable hifi rack would be and I thought I found it when I saw these. Alas, it's not to be.

Yes. Most of the time eBay.

Higher end RF stuff like this still tends to fetch a pretty penny on ebay tho.

It is a nice little unit to have on the desk during repairs, etc. I have not had any issues with it. Looks to be reasonably accurate.

Sure!

The ZNL is a hybrid instrument; it is both a VNA and a spectrum analyzer. I am also measuring IM3 not THD. But either way, the results are normal. The AFQ is much better than what is measured. The RTO and ZNL instruments are not as linear as the AFQ which is to be expected.

The power supply is not made by R&S. It is made by Lambda.

@@Thesignalpath I'd have to say the same comment applies. Lambda is probably the most prestigious PSU OEM on the market. What you found on that board is some really weak sauce at their level of play.
