Good Suggestion Lisa_Maree ( and good to see another electronics savy member with us here
)...
If the damage is only the transorb(s) if there are any and NOT the 5V and 12V Regulators that got cooked, it might be able to be powered in an unprotected from overvoltage state by removing the short as a result of a suspected shorted transorb(s) that did its/their job.
But if introduced to overvoltage again under no protection, you risk burning out the internal drive components such as the Motor that spins the platters and the signal amplifier off the aperture arm and then really be in a load of hurt if you have important data on the platters. If you blow the amplifier that is internal to the drive or the motor then the drive would have to go to a recovery center to get the data back by carefully swapping the aperture/heads/amp and if it doesnt spin on its own, they will have to do their magic to make it spin. ( Not a cheap procedure. Saw a company shell out $1500 once for their data to be recovered. )
Just wanted to mention this in case anyone other than Ryuk reads this in the future and has a similar issue. Powering up this way, if removing transorbs and short goes away, comes at a level of risk!
*Also if the person with the issue can not identify the type of component that failed, but know its bad because it got cooked. Removal of the component if a series circuit component will just mean that the drive will most likely not operate, while if a parallel circuit component, there is a very slim chance that the drive might come to life and be able to be used long enough to get the data off of it if you removed overvoltage/power filtering components.
