I am trying to find an original replacement hard drive for my pc.

[DALE707]

The on board diagnostics tell me there is no hard drive installed on my computer. This happened after i had a very brief power outage during a recent storm.

You don't necessarily need the same model
You can look at the features, and buy a similar one, from another brand if you want.

If you have an HDD, you may even be able to replace it with an SSD.
