Problems Accessing FAT16 Over 2.0GB

"Microsoft does not recommend using MS-DOS or Windows 95/98 with a 4 GB FAT16 drive created in Windows NT. If you use Windows NT's dual boot feature to boot MS-DOS or Windows 95/98, you may be able to access the drive, but you may experience unexpected behavior. In particular, some programs or utilities may incorrectly report that no free space (0 bytes) exists on the drive.

"In addition, you cannot run Windows 95/98 Setup if your computer has a FAT16 drive created by Windows NT.

"For example, during Windows 98 Setup you receive the following error message if your system has a FAT16 drive larger than 2 GB:

Setup has detected that your hard drive has a 64K-cluster FAT partition. Because ScanDisk does not work on disks with this cluster size, Setup cannot continue. To complete Setup, you must repartition your hard drive, format the partition with a FAT file system that has a cluster size of 32K or less, and then restart Setup.

"Other problems accessing FAT16 drives larger than 2 GB in Windows 95/98 may include the following:

• Running the Defrag tool on the drive causes a "Divide by zero" error message or the Defrag tool stops responding (hangs).
• ScanDisk for MS-DOS stops responding (hangs) or causes an "Out of memory" error message.
• The Chkdsk tool may report multiple "allocation errors" on the drive.

"ScanDisk for Windows typically runs without error on 64k cluster FAT16 drives and shows 64K clusters/allocation units on the Summary dialog."
