I am facing this problem with Windows XP. Recently I bought a 120 GB Samsung HDD and loaded WinXp on it. Then I copied stuff from my old HDD to it. After doing that I installed some s/w like Winrar and all onto it. When I started running these s/w , got an error, stating that I have to do a chkdsk, which I did and it ran almost 20 mins ( I restarted the PC and let the CHKDSK run). It converted "fragments to files". After that, it changed my folders in Program files of Mozilla, Acrobat Reader, Wirar into files, which cannot be opened. Even if u rename the extn to dir, it does not work. So I formatted the sys and re-installed XP and again got the same prob described above. Folders turn into files and the programs do not work Did a virus scan using Kaspersky, nothing turned up. Can anyone suggest what is the problem here Do I need to format it the 3rd time ???
