One of my hardrive is showing signs of instability and needs to be replaced.i came across this drive posted by Nutech.Hitachi 1TB SATA which is obviously cheap @ 2,000.They could not provide me the model number co'z it is not printed on the sticker label but instead told me that it's somewhat "generic".Does anybody here had bought these products and have first hand experience on using these products?or any opinion will greatly help me with my choice.I'll be using it for OS and data purposes...
