Hello,I m using Win Xp sp2 and my hdd is of 250 GB.Few days ago, I bought a Portable Usb External hard drive of 500 GB. I used this to save files like people use pen drive.I had saved almost 300 GB. But now when I plug in the usb drive(500)GB. it shows that i has 1.73 GB of memory.After that I have gone to Disk management option there I have found that ---Disk 1(basic) 465.76 GB(online)----N: 1.76 GB NTFS healthy(ACtive)----464.00 GB unllocated. Now what should i do? How can I get my old files which I have saved in this UsB hard drive?
