think about this...buyer want WD but received seagate instead. Then found not working and send it back to seller. The seller accused buyer of changing the HDD parts.

Do you think buyer keep lots of HDD parts to change? Do you think so lucky that buyer suddenly have parts for seagate to change when he wanted WD in the first place?

This is the kind of typical seller that I never deal with. When I sell, I said personal warranty and I mean it. Other sellers just say it for fun to sell their product and then when have problem blame all sorts of things.

Look at the circumstances. Who will you believe? Buyer or seller?
