[Oh no, another noob asking for help :roll: ]
Anyways, Hello!

Im sure youre all here more pro˙s than I am noob, but hope you˙ll find a bit time of yours to at least try to help me.

Okay, so I got this 500GB WD USB HDD some time (years) ago. But drive then started behaving as follows:

1. Plugged in,
2. Drive spinup,
3. Reading something a bit, (no "bad" sounds, only healthy, working HDD clicking noises),
4. Spinoff,
5. Go to sleep and do not wake until power cycled.

Whole it took like 10 secs, nothing showing up of course, not even sound of new recogized PnP device.


So I thought PCB issue! Ordered one, swapped both EEPROMs aaand, nothing. I did it some time ago, so I dont remeber what happened and whatnot but it definitely wasnt working. (I think HDD didnt even spin up it was just chillin there like it wasnt suposed to do anything).

Image

I was desperate. And dumb (okay, im still dumb). So I did what I thought was sensible idea.... OMG Im embarrased.... I mixed and matched the EEPROM Chips. (not the position like they have different footprint). It achieved one thing although I still dont know if its good or bad sign: Drive now shows up...
As... "WD My Passport 07AE USB, MBR, 0,50KB :lol: "

So... yeah that˙s the current state, hoping someone knows what to do try next.

Here I am some time later, and with enough free time around decided to poke at it again.
BUT, fear not, because I˙m not ordinary "Save my data" noob, I˙m an UltraNoob™! Just - I have some basic understanding of Disk drives, physical as well as logical, also, I have a decent soldering skills, hot air reflow, and EEPROOM programmer, so I can even dump those EEPROOMs here if anyone of you could make some sense of it (I was looking at the sea of FF˙s for a few minutes now, and it didn˙t help me in any way yet :lol: )

I˙m sure there will be a TON of things and terminologies I won˙t understand, but I˙ll just ask, no shame...


Thank You!

Here are the dumps of the EEPROOMS:

AFAICT, 10A2 is the PID for a WD Elements.

My Passport would be encrypted, Elements is not.

Okay, so both those WINBONDs seems to be the original, so I marked the possibly originals completely other way around :lol: well, nevermind, lets just say I marked "originals" as those on the replacement PCB...

Anyways, it still doesn´t work... ...At the time I was writing this...


But, then I figured, I don´t need content of those other EEPROOMs (for passport) anyways and I had 2 boards of which I didnt know which one is working and which one is broken.

And the other 2 flash were same sizes anyways so I overwrote them with the correct memory content for my HDD, from corresponding winbond EEPROOMs.

So now I had 2 PCBs, on one apparentely original winbond EEPROOMs, on the second other two EEPROOMs with now identical memory content, didn´t know which one worked. The one with the winbond has not worked so I just tried the other one, and...

It right up showed in system, loaded partitions, and all data appear to be fully readable, I have no idea what´s going on.... But it works!

The NTFS had some filesystem errors, checkdisk handled that, and now I´m doing surface test, just in case something shows up, and then off with the data!

Only thing I haven´t figured out is why?. Why it hasn´t worked and why it works with copied EEPROOMs? I don´t know, but perhaps some of you might know...

OF course, not to forget BIG THANKS to fzabkar! I would not be here with (for) now working drive here without his help! I very much appreceiate that dump analysis!
