Hi friends, sorry for the delay, I didn't have the donor hard drives to purchase, I made the purchase and they came from another state very far away, more than 3,000 km, there was a delay in delivery due to logistics.
Well, with your help, I purchased 2 donor HDs and another HD to compare the firmware and use of the PCB.
Donor 01: 160GB SEAGATE MODEL: ST3160811AS S/N: 5PT1DHBF Barracuda 7200.9 FW:
3.AAE P/N: 9CC132-302, Date code: 2007-03-25 Site Code: WU PCB: 100428473 REV: B country china
Donor 02: 80GB MAXTOR Model: STM380211AS S/N: 6PT3AH1T, P/N: 9DR111-326, FW: 3.AAE P/N: 9DR111-326, Date code: 2007-02-25, Site code: SU, pcb100422559 REV: B country china
Donor PCB 03: 80GB SEAGATE MODEL ST380215AS, S/N: 9QZ6SMTP, P/N: 9CY111-305, FW: 3.AAD Date code: 2007-12-13, site code: TK, PCB: 100422559 REV: C country :Thailand
Well, I did, cleaning the disk, as the customer reported that he opened the disk himself and removed the label and threw it away more than 8 years ago, it has several scratches and contamination and left only the hard drive without the label stored, and that he did not change the PCB.
Well, I compared donor 1 with the patient HD and they are very similar.
Patient Serial: 5PT1DGPB, Cover Number: 6317 3W101270220 2WTW070215, QR code near the motor: 100404223 J1078 3267 Drawing on HDA Similar, Reading head Qr CODE TL2-K AGB3-L 6738DBV68329B3L03
Donor Serial: 5PT1DHBF, Number on Cover: 6317 3W101270220 2WTW070213, QR code near the engine: 100404223 J1211 3267 Drawing on HDA Similar. QR CODE TL2-K AGB3-L 6737DABQB321B3L03
When changing the head, the disk turns on and spins and remains in busy mode, I took terminal output in photos, reading test for SEAGATE U5 and F3 and maxtor.
No disk identification, so I did a test with the original donor PCB board with original donor ROM, and the disk turned on and recognized as MAXTOR STM38021AS S/N: 5PT1DPGB Firmware: 3. AAE
80GB
But when accessing the data the disk did not access the data, when trying to read it due to the scratches on the magnetic plate the head died.
with the reference MAXTOR STM38021AS recognized by MRT, I used the second maxtor hd

Donor Serial: 6PT3AH1T, Cover Number: 6317 3W101270129 2WTW070128, QR code near the engine: 100396884 034656 1297 Different HDA drawing. Different QR CODE.
I used the patient's PCB again, it is in busy mode, when using the original donor's PCB it turns on and turns and recognizes MAXTOR STM38021AS S/N: 5PT1DPGB Firmware:
3. AAE 80GB . When trying to mount the image and read it, it doesn't read anything and the head hits the disk scratches again and dies.
I opened the 80GB Seagate and the structure is different and has a head and the PCB board does not work or rotate to keep busy on the patient
The question is whether the head recognition is correct, or whether it was taken from the PCB's RAM memory cache or whether someone changed the disk's fw years ago.
And if it's worth trying more donor hard drives and if I buy more Seagates ST3160811AS 160GB hard drives, OR MAXTOR STM38021AS 80GB hard drives.
