There is a way to format MyDocs from the file manager?
I am not familiar with many GUI components as it is easier for me to ssh in and use normal linux commands.
This is one reason why I am loathe to upgrade to some locked down Android with sketchy spyware apps.

Long tap on the drive icon in File Manager will pop up a context menu offering "Details" and "Format".

Your options for mount are screwed

This only lets root handle files and folders. The correct options are like

Code:

/dev/mmcblk0p1 on /home/user/MyDocs type vfat (rw,noauto,nodev,exec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0000,rodir)

Just formatted the MyDocs dir, but still having the permissions issue.

this is /etc/fstab again it has been a while but it looks fine to me and matches the /etc/fstab in my good N900, do I need to futz with the generating script to add uid/gid??

Code:

# This file was generated by script /etc/event.d/rcS-late
# !!! Do not edit this file. It will be overwritten in next device startup !!!
# If you want static /etc/fstab add genfstab="0" to file /etc/default/mount-opts
rootfs / rootfs rw 0 0
ubi0:rootfs / ubifs rw,bulk_read,no_chk_data_crc 0 0
/dev/mmcblk0p2 /home ext3 defaults 0 2
/home/opt /opt none bind 0 0
/dev/mmcblk0p1 /home/user/MyDocs vfat defaults 0 2
/dev/mmcblk0p3 none swap sw 0 0

and this is the result of mount, see the (rw) so I dont know.....

Code:

/dev/mmcblk0p1 on /home/user/MyDocs type vfat (rw)

Just looked inside the 'formatted' mydocs, ~~everythig is still there,~~ sudo fdisk and mkfs.vfat is next! and that worked perfectly as a format but failed to make the directory writable...
I was mistaken the stuff I saw in MyDocs was was just the video clips, audio clips, documents, etc auto-added by the N900.
So WTF!? it was formatted, mounts rw, but still cant write as a user??

As micha said, your mount options in /etc/fstab are screwed.
Correct entry in fstab has to be:

Code:

/dev/mmcblk0p1 /home/user/MyDocs vfat noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir 0 0

Thanks michaaa62 and peterleinchen I hadnt hit update form yesterday I guess.
This is the contents of /etc/event.d/rcS-late which generates /etc/fstab I want guidance so I dont hose it and brick my N900 as I cant reflash(broken USB)

Check /etc/default/mount-opts.
This is my entry (stock, no CSSU):

Code:

# Options for mounting user's filesystems

home_opts="rw,noatime,errors=continue,commit=1,data=writeback"
fat_opts="noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir"

normal exit 0

this is the /etc/fstab generated which seems to be fine on the good N900, again I may be missing something

Code:

# This file was generated by script /etc/event.d/rcS-late
# !!! Do not edit this file. It will be overwritten in next device startup !!!
# If you want static /etc/fstab add genfstab="0" to file /etc/default/mount-opts-overwrite

ok /etc/default/mount-opts bad N900

Code:

# Options for mounting user's filesystems

home_opts="rw,noatime,errors=continue,commit=1,data=writeback"
fat_opts="noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir"

good N900

Code:

# Options for mounting user's filesystems

home_opts="rw,noatime,errors=continue,commit=1,data=writeback"
fat_opts="noauto,nodev,noexec,nosuid,noatime,nodiratime,utf8,uid=29999,shortname=mixed,dmask=000,fmask=0133,rodir"

So a quick review shows us all with the same options, is it time to try forcing something?

(edit)In a simpler time I dont think I ever used the rodir option...
