Seagate F3 7200.11 only ROM access

[maddin]

Hello, I got a new MRT tool and I am still learning and training on some of my old drives.

Imaging drives was quite easy to get and I was able to recover all of them except one. This one don't identify itself. So I was first time opening the Seagate-Tools and try to read some Informations...

Till now I found out:
1) When I wait till the drive become ready (DRD-Light is green) then the drive don't identify and he dont show a serial-number, firmware-version or even the capacity.
2) When I start the F3-Tool directly after powering on the drive it identifies with S/N, Firmware-Version and Capacity correct.

The initial Scan (ATA mode) results with the following:

Code:

I also can't get the terminal-connection running - not by selecting Terminal-Mode immideatly and not by switching after the scan to terminal mode. The only thing which I can access at the Moment is the ROM.

It's a Seagate 7200.11 drive with 250GB (ST3250310NS) with Firmware SN04.

What I could do form there on?
Flash a new firmware with the ISO from Seagate?
Fix the firmware in some way with one of the MRT-Options?
Is maybe something with the PCB wrong? (I checked it under a 10x microscope for burnmarks, bad connections of SMDs and other visible damages)

I was also googeling and searching here but only thing I found was:

Damn UDMA not always works on NS
It is working now, i did it manually.

... What exact does that mean?

What does say terminal log in the moment when you power on the drive?

Nothing - no error, no F3 > prompt. It just stay complete empty...

When I try to use the ASCII terminal mode to read something I get an "Serial port error..." in the Log-tab.

You have to short read channel on those

maddin, Hello.. I'm here with the same serial port problem for some Seagate drives that I had terminal access two days ago.
I'm having trouble with all Rosewood family, even with good ones, working perfectly. With the same adapter I'm getting terminal access on one failed head Pharaoh drive.
I had the same problem with MRT two months ago and it vanished out of nothing. One day it was not working, didn't do anything and the other day it worked again.
I really don't know what it can be, and I'm here stuck again with this problem.
