Dear All, I am new here, just logged in, because I am sweating now, and I need deperate help. Here is the config for my sys: AMD Athlon 2800+ on a Asus K8V-X MoBo. I owned 40GB and 20GB Seagate PATA. The 20 was my primary master. I bought a Seagate Barracuda 7200.9 160GB SATA a few days ago and have been trying to install it. I have it successfully setup as my primary now, and the Win XP Sp2 is setup up here. (while setup, I had disconnected my other 2 IDEs) So, then I decided to connect them and transfer all the data to the SATA, since I want to get rid of the IDE HDDs. I connect the 20GB, while bootup, it takes some extra time than usual. Once XP is loaded and running, I open explorer and theres no 20gb HDD at all! Upon further investigation, it tells me that the 20GB is an 'unpartitioned space' !!! I rushed to my friends PC and there, Win as well as Linux tell me its unpartitioned!! Holy god! And the same thing with my 40GB too! I don't understand it! Now I'm in deep trouble. Both my HDDs are 'unpartitioned' and I have all the data I have been working on for years on them! Please please help me. I want to recover my data back as well as understand why this is happening. Thanking you in anticipation, Warm Regards, Rahul Sangole.
