Re: Cannot change permissions on a mountable drive

[Hong F Du]

The /mnt/dosE is a fat16 file system which is on a ide hard drive from my dual-boot NT/Linux system. It is setup as msdos type with auto translation mode when mounted. As a root, I can rwx the mounted /mnt/dosE. Now I want it to be read and writable for USERS group too, that makes problem appear. feng Tim Walberg wrote: > On 07/19/2000 14:28 -0400, Hong F Du wrote: > >> Hi All, > >> > >> I have a dos formatted drive /mnt/dosE, its permission is 761.
