Thank YOU, I appreciate the responses. The sticker on the PCB has 100335769 G 7533zb2d

The largest chip has a series of numbers, looks like ST E 100328754 84387A2 vq33drp AA2a3 twn 99 501

Second largest chip: Samsung 501 K4S641632H-UC60 and in tiny print too small for these eyes S6416 ZHW663gdn

Thanks again,

What are the symptoms of your bad drive? PCB might not be the answer.

Here's a photo. I can try it without the flash and see if it comes out better.

The drive was in a PC I assembled, ran for maybe 3 years, when I powered down it would not restart and the BIOS was indicating that there was no disk found. The HD was hot to the touch. I tried installing it in another working PC, but its BIOS would also not recognize the drive. And I tried an external USB drive enclosure - same results. It never made the clacking noise. Doesn't spin. There is the slightest hum or buzzing noise, very faint.

This photo is a little better

If your drive is buzzing or humming, your motor may be seized or heads stuck to the motor... Either way, you may have a physically damaged hard drive.

You might have a seized drive, but heads do not stick to a motor or a platter/s on those models. Most likely platters spin at a higher speed from average, which causes a temperature to rise above normal. Have it checked by a data recovery pro. to diagnose exact problem if you care about your data....

I have this pcb PM me for details .
