I have an old Western Digital Hard Disk (20GB) Dated 26 Dec 1999. I got it out of an old Compaq and I’m trying to see if it works. It has been sitting for over 15 years (in humid/hot environment) so it might be stuck. I took the board off of the drive and nothing looks damaged. Is there a way I can measure the control board to see if power is being sent to the drive motor? Keep in mind this is not a SATA disk.
Probably a SCSI drive. I have had luck by gently tapping the side with a hammer. Also try putting it in the freezer for an hour or so.
@carsman248 by the image you posted your HDD is a WD200AA-60ANA0 Western Digital Caviar 20GB 5400RPM ATA-66 2MB Cache 3.5-inch Internal drive. It is an IDE drive. What voltages do you get on the connector? Post some pictures of the PCB and point out which IC gets hot. See if there are any marking on it. It is possible it heats up because your drive is to gummed up. The connection should be one Common and three signal lines (it’s a stepper motor so it works a little different since this is a 3phase motor). Voltage should be 5V16V depending on the PCB I start checking for 5V first and expect 12V. Do you have any identifier on the motor. Do not just connect a power supply to your motor…… if anything you need something like this https://www.digikey.in/en/articles/why-a… and remember you can purchase controllers https://www.banggood.in/3pcs-5V-12V-DC-B… like this
