Is it possible to convert NTSF HDD to FAT32 using only the CMD command?

i don't think so

http://www.AomeiTech.com has a free converter that goes both ways.......

....and it also lets you convert between NTFS & FAT32.

Don't do any conversion unless the partition is at least 25% free because some file system converters apparently need quite a bit more room than a calculation of the amount of slack will indicate. I really don't like converting a partition without first backing at least that partition onto another hard drive.

and make sure you have a backup

The other thing to consider is that I believe FAT32 has a 4.xx gigabyte file size limit. Only important is you have any large files (high quality movies, ISO images, etc).

I'm unsure what the conversion process would do when it hits a large file like that, but I bet dollars to donuts it won't be pretty.

Why are you trying to convert it to FAT32? For OS X compatibility?

Its possible to convert Fat32 To NTFS without losing data by cmd convert command but i think vice versa is also possible.

CONVERT volume /FS:NTFS [/V] [/CvtArea:filename] [/NoSecurity] [/X]


volume Specifies the drive letter (followed by a colon),
mount point, or volume name.
/FS:NTFS Specifies that the volume will be converted to NTFS.
/V Specifies that Convert will be run in verbose mode.
/CvtArea:filename
Specifies a contiguous file in the root directory
that will be the place holder for NTFS system files.
/NoSecurity Specifies that the security settings on the converted
files and directories allow access by all users.
/X Forces the volume to dismount first if necessary.
All open handles to the volume will not be valid.

Nope, the built-in convert command is one-way:

exFAT may be the better FS to use, as it's supported by the latest versions of both Windows and OS X:

Yeah, i can confirm that too. Did some research on that long time ago, it's possible as said above, but only as a one way conversion.

It feels like OP has no backup. Otherwise it would be easy to just reformat the drive and restore
