Mac HD format was changed to Win NT mysteriously

Specs: Macintosh OS X 10.5.7, 3 GB
I use Mac and WIndows 7 to write to a 1.5 TB ext hard drive that was formatted to NTFS-3G. When I tried to write to it this morning, it wouldn't let me (read only) and the Mac properties said it was Windows NT! I have been using this drive with both systems since I got it more than a year ago so how come it changed formats without me doing anything - and I DIDN'T! This is driving me nuts as I have a ton of Mac and Win stuff on the drive!

Is there a way of changing this back without re-formatting the drive? How could this happen in the first place? I always eject or safely remove the drive before I turn it off - HELP!!!!!!!

You said it was formatted to NTFS. So it was always an NT drive. Why you can't write to it I don't know, but Mac NTFS support has always been imperfect which may have led to corruption of the filesystem. Try doing a "chkdsk" in Windows (telling it not to write corrections to the drive) to see what it reports.

Okay, got a bit of a hint from my son the Geek who reminded me (I didn't know) that NTFS-3G is a driver that allows multi OS access so I will do a little more research on this and see what I can find - it's possible the 3G driver got corrupted or blitzed somehow - stay tuned!

The post rather suggests no backup has been taken of the important information on the drive concerned.

If so, anyone reading here - Take Note!

Good Luck - Keep us posted.

No solution has been found and it looks like I have to back up my drive (I can read it but can't write to it) to a spare 2 TB drive, reformat it, and then transfer the data back - what a pain - anyone know a free, reliable backup/transfer program?????
