had the PCB swap with a proper ROM exchange. but it's not powering up. SMOOTH chip on original chip was damaged- confirmed. technician suspects a stuck motor bearing. motor winding is showing enough resistance. what should be the next step?

Hi, It's from a Freeagent Go portable. I left PC on for overnight downloads with portable hdd. at morning the system was on standby mode and the HDD LED was off. there was a burning smell through the USB port on the casing. removed the casing and connected it to an external USB->SATA connector, the drive was spinning, but not at the full speed. It wasn't getting detected in BIOS too. again connected it to the original casing, the LED's were blinking on and off. now it's not at all spinning up. there are no visible damages on PCB. is it a PCB damage. how can I confirm it? Any help is greatly appreciated. Specs: Seagate Momentus 5400.6 320GB ST9320325AS FW: 0001BSM1 PCB : 100536286 RevB Thanking you in advance. Vipin.
