problem with my favorite data recovery tool for microsd cards

[@hightttech]

Good video. Good reminder to have two of everything for sanity checks. Or known good devices put aside for reference. I worked with a guy who FREQUENTLY condemned power supplies and battery chargers for low voltage. He was sick one day, so i had to finish one of his jobs; install a new PSU in a device. I did prelim test and, to my surprise, voltage GOOD. I fully load system for extended burn-in: PASS. I test with my backup DMM: SAME. Turns out, this 50+ y/o tech was using the same DMM for 30+ years, never had it cal'd, and had no 2nd DMM. His only DMM was reading LOW, and he hadn't a clue.

[@hddrecoveryservices]

Exactly. I totally agree

[@pr0xZen]

Having two of everything isn't always realistic, but backups are good rules of thumb. Especially if you have revenue enabling it and the thing failing without backup solution meaning down time with loss of revenue. If you don't have backup, inspecting your gear and your own process becomes extra important.

[@hightttech]

@@pr0xZen : I understand that duplicating extremely expensive or huge gear might not be possible, thus having a PM schedule for all gear, and performance testing with known good devices is your duty when clients are paying for answers.

Love your work man. Glad to see you are still doing well.

[@hddrecoveryservices]

Much appreciated!

[@circuitsable]

Nice to see a change of a repair. Your hands are so steady! Great content as always.

[@hddrecoveryservices]

Thanks 👍

Tool failure is getting more common unfortunately as quality of parts degrades. I've had a professional EPROM programmer that stopped working after about 5000 EPROM writes; it turned out to be a bad 48 pin socket. I replaced the no name socket with a 3M one I purchased from Digikey, and it's been serving me well ever since.

[@Trailtraveller]

There is also a contact-cleaner which cleans and lubricates the switches much better.

[@TheDopalgangr]

Great explanation of those adapters. I have about ten of them and the instructions that came with them were not that great. You gave me good understanding of how they should work! Thanks

[@hddrecoveryservices]

No problem, glad it helped.

[@krzbrew]

Ah, the frustration of having to repair first the tools before the device you intended to repair with those tools...

[@hddrecoveryservices]

:)

[@hanaloginstruments8930]

Does the: Multicom Acelabs RBA -> RB0? RBB -> RB1? Also which is alcohol name and flux you use now i see on some video but forgot name

[@MkmeOrg]

Nice catch

[@Vladimir-hq1ne]

Let's see (video maybe?) if replacement switches would be in an accord to quality?

[@abx42]

That's crazy for S&P. Is that is pure shipping or with duty?

[@ianmorris8534]

Thanks for the upload :)

[@hddrecoveryservices]

No problem!

[@Vladimir-hq1ne]

And what was the price of that adapter board, I wonder?

[@hightttech]

Whatever is was, he's made his money back many times over with it.

[@Vladimir-hq1ne]

@@hightttech well, I meant that it was a faulty product... Cause that seemed he neeeeded to repair/reingeneer that, that was the case: no quality control at all, alas 😒

[@hddrecoveryservices]

I've had this adapter for many years now. I will take the switches apart someday when new ones get here to see what stopped conductivity

[@digidoidit]

у меня каретка для sop8 устала, кинул в ультразвук на 30 минут. всё как новая. думаю и тут этот фокус пройдёт. ток сушить нужно на нижнем подогреве.

[@ftt2757]

Nice another repair !

[@hddrecoveryservices]

Thanks 👍

[@chandigarhdatarecovery]

Erkin, Its very common for these to go bad , i am sure there are many better switch brands in the market , might be replacing these with that better brand would be better , i used to design eprom programmers at one time and this was very common failure , when you solder these back make sure that you are very quick with soldering because its the heat that kills it 75% .

[@hddrecoveryservices]

well, this specific unit is from 2017, not that I toggle the switches on it too much, but 7 years is a long time :)

[@hddrecoveryservices]

how you been, Amarbir?

[@rsuryase]

the switches probably just need cleaning with deoxit.

[@OMG_Canada]

All laboratories use an automatic logic analyzer with a NAND protocol analyzer. Or spider board adapter from ACE lab. Why you use this old stuff?

[@hddrecoveryservices]

You need to explain what you are trying to say. What old stuff are you referring too? What automatic logic analyzer and NAND protocol analyzer. Are you talking about the pinout research that comes with spider? I am genuinely interested in hearing what you are trying to say. Cheers

[@hightttech]

Sir. You have insight & knowledge about ALL LABORATORIES; that is awesome. Are you a manufacturer's rep for this type of gear? What gear specifically does EVERYONE use to make jobs easy?

[@OMG_Canada]

@@hddrecoveryservices What I'm trying to say is that now service manuals from manufacture usually are used to access to the flash card pins or a logic analyzer is installed with a NAND protocol analyzer that finds pins for use in reading. And then this configuration is applied in the ACE spider board where the pins can be configured in a convenient way. You can also read data through the controller by switching it to technical mode. Or fix/repair the translator so that the data can be read again. Finding any NAND pins takes about 10 minutes using a protocol analyzer. But how do you usually restore data? the same way as 10 years ago?

[@OMG_Canada]

​@@hightttech Yes, we are developers for government agencies and the police. If no one can recover the data, we can do it. We use the most advanced technologies. For example, now it’s easier to read data through the controller if it works normally, just like exact the same this is possible with corrupted SSD. And connect to the pins necessary only when the controller is burned out or, for example, there is no connection between the controller and the NAND memory chip.

[@leonkiriliuk]

@@OMG_Canada I think you missed the point of the adapter. These are made for devices where the NAND pinout and pin location is known and you want to access the NAND directly with no soldering because the controller is dead. This is not a general purpose adapter that can be used on all flash chips like your solution.

[@sintaxera]

😮 i like that theres even an option of sending it back to have them replaced, but hopefully anyone using this is capable of replacing the switches themselves 😂

[@Vladimir-hq1ne]

Famous Chinesium semi-conductors. Either these conduct or not! 😁

[@rosariodagosto6484]

MATE THEY LOOK LIKE WATCH BAND SPRINGS

[@hddrecoveryservices]

Haha, I know what you mean

[@Alan_Skywalker]

just buy some switches and replace them :X Takes one dollar for like 20 of them here.

[@hve.d]

Ого, а я то подозревал что ты из росии:)

[@hddrecoveryservices]

Я жил там в лихие 90е :)

[@Irilia_neko]

It's not a good idea to use a physical switch in this situation

[@Irilia_neko]

It's better to use an electronic switch which is way more durable, but also way more expensive to implement
