Hi,
I received an old ST3250820AS HDD that suffered an unpleasant shock: the owner managed to destroy the crystal. From what I checked on an identical PCB model, the piece is a TXC with the dimensions of 8mm x 4.5mm but I'm not sure if the value is 30.000Hz or 10.000Hz(?!). I would like to know with which model this piece could be replaced because I do not want to do anything stupid.
Thank you.

You can solder 10Mhz Crystal.

Hello everyone, sorry for my poor english, because i using google translator.

I searched for this HP oem HDD with the same firmware, the same chip (LSI) and the same memory (Samsung). I found a lot of combinations between Agere/ST/LSI chip and Entrontech/Samsung/Hynix memory that had only 30MHz crystal. I did not know how important the value (more precisely the difference between the two values).

I will replace that crystal as pikus_09 suggested, after I get rid of the "quarantine" period I'm going through now.
Thank you both.

Could that be a 40MHz crystal? 10MHz seems much too slow.

These crystals kill me
I found 10MHz crystal on the same pcb, others have 30 MHz, not 40MHz.

ISTM that the "1" is actually a faded "3".

The PCB at the following link has the same MCU numbers as your patient:

Ok, thanks for the tips. I will return with the result after they do the replacement, but I still have to wait until I leave the convalescence period.
