I upgraded from Windows 98 to Windows 2000 professional and now I cannot access my second disk drive (D:). When I try to open it, it prompts to reformat the disk. Is there any way to do this without losing all of the data on the drive?

Convert it to NTFS.

I tried to convert using a command line, but I get this message: "The type of the file system is RAW. CONVERT is not available for RAW drives." Also, the prompt to reformat warns that all data will be erased from the drive if I format it that way.

try partition magic. It will convert w/o losing any info. Also allow you to resize partition w/ no loss either. Samantha

You don't need to convert to NTFS. Win2K will read FAT16, FAT32, and NTFS partitions. you have a corrupt partition table or a bad hard drive. And this being the case, Partition Magic won't work either. You might try putting the drive in another system that has Win98 on it and see if it can read the drive, but don't get your hopes up.

Cravewn Moorehead is exactly right. You can't convert a drive to ntfs if you can't access it. Make sure the drives are configured correctly as master/slave not cable select. Go into disk management [control panel/administation tools/computer management/disk manager],which you don't mention doing, and allow w2k to write a signature to the drive. This alone can deny you access to the drive in w2k. Otherwise follow the suggestion of reading the drive on a 98 box and offloading your data. Note: do you see the value of backup BEFORE a major change?

I've created a boot Win2K SP4 setup CD. It automatically partitions hard disks and formats them. It's a small possibility, but is this the case? Was anything repartitioned/reformatted (apart from the system partition) when you set up win 2k?
