I installed Windows 2000 server and switched over to the NTFS. I reformatted my harddrive and installed windows 98 again. I was having trouble reformatting so I reformatted via DOS this time - something I have never done before with this computer, in order to get my computer back to the FAT32 file system. I did this about a month ago. I just tried to defragment my c drive for the first time since I switched from NTFS back to FAT32. my defragger gets to about 29% and then stops. the defragger reports that there are errors on the drive. I have a one year old computer so I didn't suspect the hardware and figured the file system conversion could be the problem. Can anyone help me with this matter. the wonderful world of microsoft help does not give you anything remotely resembling a help topic other than how to run the dumb thing ;-). there's nothing on troubleshooting
