I have a HP Pavilion a1600n computer with WinXP. I was thinking about getting an external harddrive for back-up. "My Computer" lists two harddrives: HP Pavilion C and HP Recovery D. "C" uses File System NTFS with 177GB total space and 157GB free space. "D" uses File System FAT32 with 8.83GB total space and 568MB free space.
Do I have two different harddrives? Do I need to buy another hardrive to back-up my files? Thanks.
