A client staff member near Solihull had a NTLDR sort of error on the laptop and took it to the shop who said it was a dead drive and replaced it. She was gutted that the data and all her family photos had been lost. I pointed out that NTLDR is usually a corrupt registry and totally repairable and that it was highly likely the hard drive was fine.
I expressed a view over the situation and said she needs to go back to the shop and get the old drive as she has a right to ownership. She did but it had been 'disposed off', which in my mind means 'sold on'.
She was charged £160.
I once worked in a computer shop around 1999, I was forced to sell a 56k modem (internal) inc installation for something like £90, but the worst rip off was the old CD-to-motherboard audio cable. Old bloke came in the shop wanting one, I watched the owner sell him one for £14.
His business lasted around 2 years, mines been going for 11. Difference is I don't rip people off.
