WD5000AAKX-08ERMA0 Spin off after some seconds

[nasdascq]

I have a WD5000AAKX-08ERMA0 hard drive that is not detected when connected to a computer under normal conditions and makes a some clicking sound.
After connecting it to the PC3000, 2 and 4 lit up without any errors, and the became ready. I backed up the modules, but only the copy0 were ok; copy 1 returned errors for all modules. In the end, the backup process finished, but several modules were corrupted in both copy 0 and copy 1, such as modules 11, 119, 68, 1B, and others.
After power-cycling the hard drive, it stayed on for a few seconds and then powered off.

Upon opening the hard disk, I found scratch marks on the platter, and one of the read/write heads was slightly bent.
I got a donor drive of the same model and performed a head swap. After powering it on, the hard drive reached the ready state without any unusual noises, but its specifications such as model, serial number, and capacity were not displayed. After uploading the loader to RAM, all the information displayed correctly, and I was able to back up the modules. Both copy 0 and copy 1 were correct , except for the same modules that were originally corrupted, such as module 11.

After running the hard disk for a short time, all specifications were correct except the capacity, which showed as 0.
After a while, the drive began to behave like it did before the head swap, powering off a few seconds after turning on.

I have not powered it on again until I can determine the cause of the drive powering off again.

What issue do you think this hard drive has?

After the damaged head was replaced with a good head, the drive powered off after a few seconds.
For troubleshooting, the good head was returned to its original healthy drive. The healthy drive spun up with slight head noise and scratching sounds, then powered off after a few seconds.

A hard drive can power off for various reasons, one of which is hardware issues. It seems the problem may be in the preamp, where a short circuit has reduced its resistance, causing the MCU to cut the power to prevent damage, which results in the drive shutting down. It is likely that the faulty HDD PCB has a problem that damaged both the original head and the replacement head.

To test this, a new good head along with a new, healthy PCB was installed on the faulty drive. The drive started with scratching noises, and none of the hard drive’s specifications were displayed correctly.

Could this problem be caused by severe physical damage to the platter surface?
