I have 3 hard disks of seagate in my system. One of them is a 750 GB SATA, another one is 1TB SATA and i bought another 1.5TB SATA. Now the 1.5 TB hard disk is creating errors when im trying to partition it and format it. Even though it's showing 1.369 TB im able to make only one 100GB partition and the rest is showing errors at various places. The errors are as follows : failed to read from the sector-1,39,39,63,583 of the hard disk 3. and so on and so forth. I even gave my hard disk for replacement. it came back yesterday. But it is still showing these errors. What am i supposed to do? please help. It's very urgent.
