Hi Everyone,

Need help in this case. Hitachi HTS547550A9E384 Stays BSY all the time.

I have replaced PCB but still the same.

How to make this drive go to ready state for any firmware manipulation or accessing the SA.

Do I have to Short read channel? Any Solution ?

Best Regards,

There may not be much you can do. You can try changing heads, in case the issue is a failed head. Or try just waiting for a long time to see if it comes ready eventually. Is it clicking at all?

Hello there, I've got the same prob as well. I've checked the device heads, there wasn't any damage inside the hdd. The Drive stays busy after 3 hours. There's no response. Is there a solution ?
