I purchased a used macbook pro which failed (hard drive) after two months. The shop will not honour the warranty as they say the laptop was abused. their "evidence" is the HDDScan smart report attached.
I have good reason to believe the shop manager is not honest.
There appears to be no date on this printout and it seems to me that it is not proof of misuse. appreciate any help/advice from members.

It's the "G-Shock/Free-fall Event Count" that they're referring to. For that to have been triggered 76 times is very unusual, and virtually unheard of in most use cases. Also the scan date is CLEARLY listed on the printout:

OK - that makes sense. The shop told me that the 076 referred to the force of the latest shock, not the number of times it was triggered. They also told me that the list was a sequence in time ie event 254 was the last event before failure. I bought this 2nd hand 2 months ago. If what you are saying is correct then it's had a rough history? Have i got this interpreted correctly?

SMART monitoring (which is what that report shows) does count from 0 to 255, but it's an aggregate count. If that 076 was the force of the last shock to the drive, then (depending on how they interpret it) would mean the machine was subjected to either a 76G shock (extremely unlikely) or a 7.6G shock (about 2.5x the G force experienced during a shuttle launch). I'd lean towards it being a cumulative count like the other numbers on the report, which would mean the machine got bumped around a lot while powered on.
