    Hard disk don't allow to write as normal user


    Hello to all
    (sorry again for bad writting, english isn't my main language)

    I had a problem with a HDD Samsung IDE 80Gb, after a previous format (1 month ago), i tried to format if for dual OS use, but the OS can't boot, now im trying to use it as data storage only, but WinXP shows the icon and when i try to get access, appears a message saying "The hard disk have not format", and i have downloadad ntfs-3g but "Bad File System or Super Block" message is shown . . .

    I using Debian Etch 4.0 r0

    I reformated the HD by this way:
    -fdisk /dev/hdb
    "n" new primary partition, "1" for partition, "t" and 83 for ext3 fs, "w" for writting
    - mk2fs -t ext3 /dev/hdb1
    -fsck -t ext3 /dev/hdb1

    but i can't write on the HD as normal user, also when i explore the HD it appears an icon of a folder with a lock named "lost+found", as root i can do anything

    in another forum somebody advise me to use GParted, using ext3 as filesystem . . . with the same results. . .

    After that i reformated the HDD making low level format (zero fill "dd if=/dev/zero of=/dev/hdb1") previously and using fdisk, mk2fs, fsck, and, again i cant' write as normal user

    i also have changed the fstab adding the mount point with rw perrmision like this:
    /dev/hdb1 /media/HD rw,user,noauto 0 0 (adding also umask=0 at the mount options)
    and the folder in /media has all permissions with owner and group of my normal user account

    What else should i try???

    Thank you for your time
    See you

    Execute this
    Code:
    su 
    fdisk -l
    * Its small L in fdisk -l.
    Post output here.
    It is amazing what you can accomplish if you do not care who gets the credit.

    Execute this
    Code:
    su -
    chown userid:groupid /media/HD
    Execute id command to check userid and groupid of normal user.

    i did it, replacing userid:groupid with the numbers shown in "id username", in my case 1000 for both

    uid=1000(edgar), gid=1000(edgar), grupos=1000(edgar), 4(adm), 6(disk), 20(dialout), 24(cdrom), 25(floppy), 29(audio), 44(video), 46(plugdev), 113(fuse)

    but still appears the lost+found icon and can't drag and drop any file to the HD nor write creating a file using an editor or console

    Thanks for the tip/hint, it was unknown for me

    Which could be the cause of this??? a kind of phisical damage on the HD??? or something in Debian?? or me???

    Thanks again
    See you

    uid=1000(edgar), gid=1000(edgar),
    Use User and Group name only.
    Code:
    su 
    chown edgar:edgar /media/HD

    with double dot??? " : " i did it with single dot "edgar.edgar",

    maybe is the problem, but i did it before separately with "chown edgar" and "chgrp edgar",

    i think that is the same as "chown edgar:edgar"

    i will try again anyway

    Thanks again
    See you

    A few moments ago, checking files i reach the root partition and see that it has the lost+found icon, and i remembered that the root partition is a primary partition and saw in somewhere that primary partitions are recomended for "hosting" a file system, and extended for "data storage" . . .

    And i been tinking, only root user can change files in a partition with a file system (files and directories as /boot /bin /etc)

    this could be the mistake???
    and should i format the HD with an extended partition???
    it's possible to format the HD only with an extended partition without a primary???

    ( ext3 can be used either primary and extended partitions ??? [ to edit fstab ])

    Yes. Only root user can edit/delete/create files/folder in those areas. Regular users have access to their /home/<user_id> folders only.
    and should and should i format the HD with an extended partition???

    Your HD has an Extended Partition ( /dev/hda3 ) already. Extended Partition is just a pointer/container only and it contains Logical Partitions. Your HD has two Logical partitions. /dev/sda5 and sda6.
    You can format any partition Primary or Logical in any FileSystem but its not possible to format Extended Partition because its just a container.

    ???
    The HD that i want to use is hdb wich dont allow to write as normal user ..

    Then, can i format it with a logical partition without create a primary partition before???

    Having a logical partition in place of a primary, it's possible that the problem will be fixed???
