Hi, I have a drive plugged in USB and I was wondering if mac has a utility like chkdsk that windows has? I know under disk utility it has something, but it usually doesn't work with external drives, or maybe it's just because it's an NTFS drive?

There has to be a terminal command or something, thanks.
 
OS X Doesn't support NTFS, so...
Why don't you just plug it into a Windows PC?
 
well actually it can read it, it just can't write to it.

So ok lets say it can recognize the drive just fine, is there not a command or anything for a chkdsk in the mac os?

OSX can read NTFS..it just can't write to it. That's normal.
 
Chkdsk involves writing back to the drive to fix errors and such. Since OS X has no NTFS write support, it can't do a chkdsk-like activity on NTFS drives. If you want to run chkdsk, connect the drive to a Windows machine.
 
yes I know that, hints why I said it does support it. The other poster said it doesn't support NTFS which it in a way does as in it reads, but doesn't write.

Just nevermind, delete post.
 
No need.

Actually you do it from the Disk Utility App.

But, as you can see OS X won't allow you to verify/repair an NTFS formatted disk.

If it was FAT32 formatted it would let you verify and repair, but not NTFS.

Need to take it to a Windows computer to chkdsk it.
