Problem renaming device with mlabel

I`m trying to rename my usb-stick with following command:

mlabel -i /dev/sdc1 ::newname

output:

Total number of sectors (15633376) not a multiple of sectors per track (62)!
Add mtools_skip_check=1 to your .mtoolsrc file to skip this test

Well, i created a file .mtoolsrc with the appropriate content.

But the label didnt change and mlabel is still complainining:

Total number of sectors (15633376) not a multiple of sectors per track (62)!
Add mtools_skip_check=1 to your .mtoolsrc file to skip this test

Any suggestions?

Re: Problem renaming device with mlabel

man mlabel

You are trying to name a partition instead of the drive.

you can even try mkfs and pass in the flag to set the label -- this will of course re-format, so make sure you don't have any data on it. Other options are e2label and tunefs

Re: Problem renaming device with mlabel

Instead of mlabel, use dosfslabel from dosfsutils.

@Inxsible: These are filesystem labels, so using sdc1 and not sdc is the correct thing to do. There's also partition labels (different thing from filesystem labels), but only with GPT.

@Gusar: dosfslabel worked fine, thank you!

dosfslabel /dev/sdc1 "newlabel"

But i still can`t see whats wrong with my approach using mlabel.

Sorry for the dumb thread.
Because i needed to use root for mlabel i had to add "mtools_skip_check=1" to /etc/mtools.conf instead of .mtoolsrc

Just signed up to thank gandhi for updating the thread after figuring out what was wrong with mlabel -- I had exactly the same problem where mdir/mlabel refuses to work and prints misleading information, and gandhi's update in #5 helped me get past this. Thanks!
