I've searched the threads and found that it's most likely due to FAT corruption while the USB cable was connected to my computer.

I tried michaaa62 "http://talk.maemo.org/showthread.php?t=71702"
solution and got a Invalid argument error message.

HTML Code:

fsck -af /dev/mmcblk0p1

fsck 1.41.3.maemo0 (12-Oct-2008)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
Cluster size is zero.

mount /dev/mmcblk0p1 /home/user/MyDocs

mount: mounting /dev/mmcblk0p1 on /home/user/MyDocs failed:
Invalid argument

Another thread recommended installing the system update but that didn't help.

Additionally when connected to my windows laptop, it recognizes the N900 as Removal Disk G and H but I can't explore.

Please help, this is the first time I've used rootsh

I think maybe you should use /usr/sbin/mmc-mount instead of mount, that way it applies all of the proper mounting options.

So I should type?:

HTML Code:

mount /usr/sbin/mmc-mount

ooks like you also have a deeper problem.
"Cluster size is zero" does not sound good, i.e. your space on your first partition is zero or not available at all.

Here is my output (with -n instead -af, just checking, no changes):
$ sudo fsck /dev/mmcblk0p1 -n
fsck 1.41.3.maemo0 (12-Oct-2008)
dosfsck 2.11, 12 Mar 2005, FAT32, LFN
/dev/mmcblk0p1: 21384 files, 442377/442377 clusters

Check partitions with
sfdisk - l

Did you reboot?
Sorry for not being helpful, but I do not know more at this stage.

--edit
Oh, and mounting should work with your commandor even
moumt /dev/mmcblk0p1
or
mount /home/user/MyDocs
as they are in /etc/fstab. I use these and have no problems.

mount /home/user/MyDocs

Thank you.
I ran fsck (rootsh) in the code above. Is (backupmenu) a different version? I'm not familiar with fsck so I will execute exactly what you say.

If that fails, and I need to make a Gparted Live CD what do I need to execute?

Sorry for all the questions. This is the first time I've "gone under the hood"

install backupmenu into your device & reboot your device with your keyboard slider open...this will boot backupmenu....now ignore any error on backupmenu startup....
once backupmenu is open look at and option to fsck your device....it will fsck all partition on your device...if there a problem it will be show in its log....
fsck your device a few times to makes sure it can fix any error....after fcsk then use option quit & reboot...remember to close your keyboard to reboot like normal...

But be prepared that 'fsck'ing that way may lead to a bricked device, as it did for me once. So backup is important!
But I really had file system problems with unreadable files and NFS stale files and so on. Your problem looks more like a partitioning problem to me (but I do not have any more advices for you).

I tried many times, but (backupmenu) fsck failed.

HTML Code:

checking mydocs...
errors may have been encountered: code : 8
fsck.ext2: Bad magic number in super-block
while trying to open /dev/mmcblk0p1
	press any key to continue

After work tomorrow, I'll download Gparted Live CD to my windows laptop. Then I'll run backupmenu (mass storage mode) and connect it to my laptop.
