Hi, I need help about a problem.

I have a Seagate 7200.12 500GB hard disk. The BIOS doesn´t recognize my hard disk. I have been searching for info but all I have found is about 7200.11, and I don´t know if it works for .12. I wrote to SeaGate and they answered me that the data recovery is not covered by warranty.

I have two months until warranty expires, but I want know if there is a way to recover the data.

Thank you.

If you want your data recovered, you'll need to send it to a data recovery professional who can properly diagnose and, hopefully, recover your data. It is is unlikely that there is anything you can do yourself that isn't going to make things worse and possibly void your warranty.

I do not suggest to do a Busy fix or LBA= 0 fix on this drive. That is not your problem. The BIOS is not seeing your drive. You problem is someplace else. You have two options on this one. One send it in for RMA - Two send it to DR company for recovery of you data then send it in for RMA.

It bit more info might also be usefull.
With the drive connected to a computer motherboard and powering on the system.......
So does the drive motor start to spin?
Does the drive make any sounds like it is attempting to initialize?
Or does the motor spin and then there is no other sound or click?
Have you tried connecting the drive to a different pc?

A don´t hear anything (maybe i´m quite deaf), and I don´t feel how it vibrates. I have tried connecting to a different pc with same result, using the SATA connection and a USB-SATA connection also.

Thanks to lcoughey and poehere for the info, i´ll write some DR company to ask about.

Apologies if my English isn´t correct.

You seem to be implying that a drive's failure to be detected by the BIOS cannot be as a consequence of a BSY fault. This is not true. In fact the well known 7200.11 BSY bug exhibits this very symptom.

This suggests that the most likely problem is a PCB fault, in which case all you need is a board swap and ROM transfer. This should cost you no more than US$50 in total.

Can you upload a detailed photo of the component side of the PCB?
