Dear All

Recently my laptop ( HP Compaq 420) has its C drive crashed. After giving to AMC company, they told me that its hard drive has some problems and they need to change it. They told me that Seagate Hardrive of 320 GB, 7200 rpm is costing Rs. 5000+taxes for HP laptop. Also when i asked them that i need my original hard drive they had returned to me WD Scorpio Black Hard Drive ( Part No. WD3200BEKT) of 7200 rpm, 320 GB.

Now i just want to check firstly that the WD hard drive they returned back to me, is it the original one or else how can i check what is the original hard drive in my laptop and secondly had they charged me right rate for seagate hard drive or not?

Please help me in this matter.
