Firmware problem is the most common problem in both HDD repair and data recovery. The general principle for firmware repair is to find the donor firmware and upload the corrupted firmware. But this is what the most bore and important problem is: how and where to find the donor firmware?
Now, depending on SA emulation tech on DC, we could avoid this terrible problem for Hitachi drive. There is a typical case about SA emulation.

Then load from file, we could access the service area and check the corrupt modules:
Now we connected the drive to Data Compass and show how SA emulation worked.
When the drive connected to DC, we can see the error status and couldn’t access to data area:
Then back to the Control page, choose the right series in “HITACHI HDD LOAD”:
A moment later, we can see the status go to “ready” status, and now we could access the data area:
