dows cannot access a partition if it uses the latest version of NTFS.
The two exceptions are Windows 2000 and Windows NT 4.0 with Ser-
vice Pack 4 or later.
For anything other than a situation with multiple operating systems the
recommended file system is NTFS.
Important
Once you convert a drive or partition to NTFS, you cannot
simply convert it back to FAT or FAT32. You will need to re-
format the drive or partition which will erase all data includ-
ing programs and personal files on the partition.
The following table describes the compatibility of each file system with
various operating systems.
NTFS FAT
FAT32
A computer running Win-
dows XP / Vista / Win-
dows® 7 or Windows 2000
can access files on an
NTFS partition. A com-
puter running Windows NT
4.0 with Service Pack 4 or
later might be able to ac-
cess some files. Other
operating systems allow
no access.
Access is avail-
able through MS-
DOS, all versions
of Windows,
Windows NT,
Windows 2000,
Windows XP /
Vista / Win-
dows® 7, and
OS/2.

only through Win-
dows 95 OSR2,
Windows 98, Win-
dows Millennium
Edition, Windows
