To update you all, I decided to put it in my ext.USB HDD case to explore it. First it was not recognised then Win asked if I wanted to 'Check disc & repair any bad sectors' so I did. This could not be carried out,after waiting 2 hours, then the result 'Too many bad sectors' I then d/loaded WDs diagnostic tool, with the same result. In for a penny etc, I decided to 'Write '0's to it..... Now nothing at all 'Dead!' So it is now consigned to the bin! You live & learn... especially by your mistakes ie, 'Don't buy used HDDs'. Just an observation here, I have noticed new IDE/Pata, HDDs are much more expensive now than they were, up to double the price of SATA drives, anyone know why? Anyway, thanks for all the help, Guys.
