Hello,
I have some problems with a hardrive WD5000AAKX. My conclusion is that it is a problem with the harddrive electronics.
I'm getting some timeouts, after which system tries to issue a reset into HDD, this helps but after few seconds the harddrive is again unresponsive, it takes 10-20 software resets to fix it or complete reboot.
Most of times reboot helps but sometimes HDD isnt recognized by BIOS and i have to do few more reboots to get it working. And I'm unable to see any pattern in when this timeouts appear.
It seems that:
There is no problem with sata controller (other HDD works fine, but it is only a SATA I)
There is no problem with OS, i have tried few reinstalls of W8 and W7. The only diffrence is that in W7 harddrive is switched into PIO mode after timeout.
There is no problem with mechanical side of HDD - I have done few complete tests and no problems/ no bad sectors.
My question is: Could this be because of faulty electronics? And if so have someone some ideas? There is some generic 128MB RAM IC, do you think that its possible that some faulty memory places could be the cause here?
The harddrive is without warranty but it would be nice if i could fix it just with few bucks component.
btw. I have tried to reflow it with hot air just for fun but nothing.
