Hi,
I am looking for a pointer on where I can find help with a problem I am
having with the IBM 1G Microdrive and Linux. The problem I am having is
not distribution specific.
The problem is that when I connect my digital camera (Olympus E-20) to
my computer via USB (or the microdrive directly to my laptop via the
PCMCIA adapter), trying to list the files on the disk displays a corrupt
directory structure:
> ls /mnt/camera
dcim
> ls /mnt/camera/dcim
100olymp
> ls -l /mnt/dcim/100olymp/

-rwxr-xr-x 1 root root 3850982 Dec 23 19:50 pc230031.jpg
...
I tried it with different units, all had the same problem.
I formatted it more then once to make sure that the directory
stucture is not corrupt and even then it displayed what seems to be a
broken directory structure (i.e. when empty).
One thing to note is that the disk is formatted as fat, i.e. it is not
ext2/3.
It is not machine specific since I tried it with my desktop (via USB) as
well as my laptop (via PCMCIA adapter).
The laptop is IDE based. The desktop is SCSI.
The 'other' OS has no problem with these drives.
$ uname -a (on laptop)
Linux seahorse 2.4.18 #3 Wed Feb 27 19:09:37 CST 2002 i686 GenuineIntel
Desktop is running kernel 2.4.7-SMP on a dual processor Athlon machine.
I can only think it might be a problem with the fat driver, any idea
what may be the problem?
Thanks,
Avi

Check to see of your drive has meta-data cache.
This is a solution to reduce power consumption in portable devices.
You may have problems with some inital data but some of the things which
these devices do is voodoo.
Also one set of images could be put to platter as memory and not disk.
