Problem with wd sata2 caviar...

[moysatos1]

Hello everyone need some help because i am going crazy i have a very big problem but can find a solution.
From the beginning someone gave me a new system so i would install windows on
tech information msi 954gcm motherboard and wd 200gb caviar sata2.
Ok now the fun starts first of all from bios loading it appears that smart has problem and prompts me to replace disk
i continue boot fro cd windows sees my disk normally and partition and the format it always stick on 0% tried quick formatting it appears ok but when windows tries to copy files on disk it almost always stops on 4% except fot 2 times that it went to 100% and restarts and windows popped up a message that disk can read from file and stops installing.
So i said bad disk no problem 5year warranty i went to the store and described the prob next day they said no problem was found on disk and we foramtted it ok.
Took the disk same thing over and over put it on 2 syatems that are running ista tried to format it from computer managment same thing stucked on 0% for over an hour tried diagnostic tools from wd same thing bad disk replace and then found very yousefull program from here MHDD booted from cd tried first diagnostic to read from disk to see if the were any bad sectors found i believe over 500 bad sectors and i tried maybe to repair nothing at all and last low-level format and stopped after formatting about 40mb and popped up the blue screen of death an error interrupted please replace disk.
Is the answer to my solution BAD DISK or am i missing something here

THANKS IN ADVANCE
sorry for my english tried my best

You have a bad disk.

The store did not find a problem because they were not using a good program to test the disk. The program they need should test each sector of the disk.
