hey guys.....upgraded frm the 7200.11 version after successfully reviving it. Now i'm on the newer 7200.12 version. S/N : 5VM0SV16 Model: ST3500418AS Firmware: CC34 The problem now is, it is able to be detected in BIOS. I'm using this as a secondary drive, so i can boot my OS. The only problem is, when i open My computer, it hangs and i can see that the hdd light is busy. Tried on external casing, same problem. "My Computer" hangs until i pull out the ext casing then only it'll recover. Tried on Linux. Same problem, still cant open the partition. I hope i can get some help from here. I have all the tools that is required to solve the problem encountered by 7200.11 series as i have done it before. Just wondering can i use the same way but just with different codes? I really appreciate your help. I have really important, personal, financial, company and family data. Pleaasssseeeeeee help me. :blushing: Thanks a lot.
