WD5000BMVV connector

[jerovsek]

Dear Sbb Kbb,

could you describe a little bit more. Is your drive still in enclosure or not? You need data or not?

Hi All!

I have a faulty WD Elements 1023 (WD7500KMVV) which shows the following behaviour:

- when plugged into USB, HDD spins up, sounds normal
- LED blinks or lights continously
- Windows Disk Management shows "eggtimer" for 2-3 minutes, nothing happens ...
- After 5-10 minutes, sometimes it is recognized as Drive E, but without file system
- Data Recovery software tell, that all sectors are bad
- When the issues started, I was still able to see the folder structure, but no content (empty)

I tried Linux and Windows, several USB cables etc. -> always the same. When the problems

I am familiar with soldering, but just want to make sure before I do something wrong:

Is this issue likely to be a faulty SATA/USB bridge chip? Could I have any success when removing C13, C18, C31 and C33 and solder a SATA cable to the E71, E72, E73 and E75 points? Or does this sound like a completely different issue to you?

Thank you guys, I really appreciate any help !

Hello All,

would someone be able to tell if the above error desciption fits to a faulty USB bridge?
I just don't want to damage the HDD even more by desoldering the capacitors, in case you say the USB bridge couldn't be the problem in this case.

Thanks !!

No, I wouldn't say the USB board is the culprit at all.

Almost certainly bad sectors on the drive (which the USB bridge doesn't like very much) or a firmware issue with the actual drive.

Shouldn't be too difficult to recover the data (at this stage) for someone with the right tools and knowledge.

Happy to take a look if you wanna ship to UK?

Hello Fritz01,

start new topic, it's better.
It could be issue with faulty USB bridge

Hello Fritz01,

It could be issue with faulty USB bridge

I bet it's not!

In fact, if the drive is sent to me for recovery, and it turns out to be the USB bridge I'll do it for free!

hi pcimage,
It's not my HDD, so I'd habe to talk to the owner. Will let you know, thanks!

A simple questions.
If i make the usb to sata bypass and the data is encrypted... can i just format the HDD and use normally???
There is some risk to use with the bypass like overheat or something like that??
Thanks

Hi.
Does anyone know what are the sata connectors and power of this card?

Thanks!

[mircot80]

I found this but it is without any description.

I found this but it is without any description.

Those appear to be the SATA Tx/Rx differential pairs, plus the +5V and Ground pins. The photo is demonstrating how to convert the drive from USB to SATA.

[mircot80]

Yes but I would like to know which is the "transmit +", "transmit -", "receive -", "receive +" and ground?



Thanks.

Same MCU, different boards. Follow the Tx/Rx pins from the SATA connector to the MCU.

Hi mircot80,

Put here pics from your PCB?

fzabkar can help you to find points
sure

I have the same WD5000BMVW-11AMCS0 with real time encryption, and I changed my failed pcb a few years ago (need swap U8 and U12). I done sata connection at that time (for nothing), and I can certainly find the right pinout if you want.

[mircot80]

how can I know if there is real time encryption?
Yes, what are the right pin out?
Thanks.

[AesEbu]

how can I know if there is real time encryption?

I think with same part number, your drive have also real time encryption. When I connected my drive with sata connection, I couldn't see any files, and it was ok with new pcb (usb 3.0 connection). No doubt on encryption with this drive.

Here are the Tx/Rx pins.
