hi,
I found some strange issue about mount. My portable hard disk has some
partitions like below:
* Device Boot Start End Blocks Id System*
*/dev/sdb1 * 63 91747214 45873576 7 HPFS/NTFS*
*/dev/sdb2 91747215 194145524 51199155 7 HPFS/NTFS*
*/dev/sdb3 194145525 312576704 59215590 7 HPFS/NTFS*
first, I mount /dev/sdb1 like this
*$ sudo /bin/mount -t ntfs -o noatime,utf8,rw,uid=1000,gid=1000,umask=022
/dev/sdb1 /media/sdb1 *
*mount: warning: /media/sdb1 seems to be mounted read-only.*
*$ echo $?*
*0*
*
*
I check the /etc/mtab,
*$ tail -5 /etc/mtab *
*devpts /dev/pts devpts rw 0 0*
*shm /dev/shm tmpfs rw,nosuid,nodev 0 0*
*/dev/sda1 /boot ext2 rw,noatime 0 0*
*/dev/sda4 /home ext4 rw,noatime 0 0*
*/dev/sdb1 /media/sdb1 ntfs ro,noatime,utf8,uid=1000,gid=1000,umask=022 0 0*
*
*
sure, i can not create file in the dir /medie/sdb1
*$ pwd&&touch haha*
*/media/sdb1*
*touch: cannot touch `haha': Read-only file system*
*
$ id
uid=1000(adamzyg) gid=1000(adamzyg) groups=1000(adamzyg),92(audio)
*
Question 1: mount with -o rw does not work, why?
second, if I continue mount /dev/sdb2 like this:
*$ sudo /bin/mount -t ntfs -o noatime,utf8,rw,uid=1000,gid=1000,umask=022
/dev/sdb2 /media/sdb2*
*$ echo $?*
*0*
*
$ tail -5 /etc/mtab
shm /dev/shm tmpfs rw,nosuid,nodev 0 0
/dev/sda1 /boot ext2 rw,noatime 0 0
/dev/sda4 /home ext4 rw,noatime 0 0
/dev/sdb1 /media/sdb1 ntfs ro,noatime,utf8,uid=1000,gid=1000,umask=022 0 0
/dev/sdb2 /media/sdb2 ntfs rw,noatime,utf8,uid=1000,gid=1000,umask=022 0 0
Strange: I also can not create file in /medie/sdb2
$ pwd&&touch haha
/media/sdb2
touch: cannot touch `haha': Permission denied
no wonder. you are using ntfs which doesn't have write support. For that
you need ntfs-3g
