I would change the pcb, because everytime i see shorts components near VCM i was never able to fix just by replacing those components, the reason was always due to faulty VCM.
You might try to pull off the capacitor, if you still see short on its pads then you know that vcm is shorted, if you don't see short once you remove the capacitor then you could solder new capacitor (but in my opinion it will notwork).

What i was saying was if you use some tool that can show the register status of the drive like MHDD, Victoria, etc or if you have any comercial firmware tool like PC-3000, MRT, HRT, etc and if you plug PCB only on ANY IBM BASED drive (arch M24, ARM based, etc) you should see this IF THE PCB IS STILL WORKING :
