Hi!

Drive details:
Seagate Barracuda 7200.12
500 GB
P/N: 9SL142-302
MDL: ST3500418AS
Platter: 1

I try to get into the data recovery business and have a HDD here, that I screwed up. There is no valuable data on it, but I want to get it working again in order to learn something.
HDD has been opened and totally disassembled (HSA removed, platter removed) and assembled in a clean room environment.
Now it spins, I hear some HSA activities that stop after some seconds and thats it. Platter still spins but nothing more.

One thing that I´ve noticed. The screwed platter clamp is not perfectly centered causing some minor vibration - I don´t know if thats the issue, but I don´t get it perfectly aligned anymore.

When I start PC3000 the BSY + PHY LEDs are always green.
Utility selection gives an error, since "Drive ID has not been read"
Manually selecting "3F Pharaoh" leads to the error "Error initializing microprogram tables".
Then starting "Alternative initialization" seems to work and I get some data from the drive (see attached log)

Now I am stuck.
How to continue?

After switching the power or resetting (and "some HSA activities that stop after some seconds and thats it"), apply Ctrl X and look at the log to see if it can see the servo and read anything.

Both copies of the SYS file 3/301 (module 1B) are unreadable. Try writing it from another similar drive or simply an empty sector (this is a log file). Then, try resetting and Ctrl X again. If the issue persists or worsens, there's a problem writing to the CA.

Thanks for the hint!

I have written 4/301 to 3/301 copy 0 and copy 1, then i repeated the command and got the following error:

I was able to do the same procedure with 3/13A but not for 3/306 (needed a file with proper size and filled with 0x00), but this wasn´t necessary anymore. Drive is now ready and I am able to make an image from it.

Thank you for your help!
