Converting an external hard drive to NTFS

[Theodore Donald Kiravatsos]

I got a Western Digital external hard drive with the FAT32 file format. I am trying to change it to NTFS.

I used the command prompt
<font color="blue">convert e: /fs:ntfs </font>
to attempt this, but then I am prompted

<font color="red"> Enter current volume label for drive E: </font>

What the heck does that mean? How should I answer this? Thanks in advance for any suggestions.
