Seagate 160GB ST3160215ACE PCB

Got this drive of E-bay to mess round with and see if I could get it going so no important data or anything.

Just wondering if the chip I have circled is the ROM that would need to be moved to a new PCB board.

Not sure exactly what the old problem was, but when the drive was connected, it would spin fine, heads would do their normal routine but it would not register with the computer. The LED light on the USB board would always be on bright, normally flashes when Reading/Writing, which lead me to believe there, might be a loose connection on the board. Cleaned all the contacts and such, and I even managed to get the drive to work perfectly for a few minutes before it was suddenly cut off.

Anyway, when I was testing the voltage points the probe slipped and now the SMOOTH chip is completely F**ked, gets very hot and will probably burn if left connected. The board was not connected to the drive when this happened and I made sure not to power the drive again just in case I damage the pre-amp.

I also want to know if this E-bay PCB board will work with the drive. The PCB numbers are the same and it looks okay. Just need a second eye. Also if anyone has a compatible board cheaper, I’ll have it J

Yes, that appears to be the flash memory. You can see thin traces running between the chip and the MCU. The chip's part number should lead you to a datasheet.

If you can see it running into the MCU and it's 25xxx then that's your man.
