Hi guys! i need some advice regarding ebay returns.. I sold a working and tested used hard drive i had on ebay, the customer has used it and installed vista on it fine and vista booted up fine, however, he said that when he was updating his drivers and programs, the pc started to restart and now won't boot into windows.. he even tried reinstalling vista from scratch..
what should I do? he is asking for a refund but the hard drive was working fine before.. any advice would be appreciated as I am fairly new to ebay.
