whats the FileSystem of external drive? Linux has ReadOnly support for NTFS. you can write in FAT32 partitions.
post contents of /etc/mtab file.

the info from the link seems to suggest that information on the HD will all be lost! I;ve got 100Gb of valuable data!

the HD is NTFS.

as i wrote earlier, you can't write in NTFS partition. you can use ntfs-3g for getting write support. check this thread for instructions on install and setup of ntfs-3g.

how do I write fat32partitions?

i am not getting it. Linux has read/write support for FAT32. you can create/Edit/delete files in FAT32. navigate to that partition and do whatever you want.

how do I post contents of /etc/mtab file.?

in terminal/konsole, type
cat /etc/mtab
no need to post its contents now.

and how do I write fat32partitions?

It is possible (indeed likely) that you have a misconfigured setting for fat32, and with your misconfigured setting for fat32, you will find only user root can write to the fat32. If that is the case, then I saw the following quote on another forum, and I thought it quite good in terms of providing a philosophical explanation.

We should not forget the real problem behind this issue is that FAT32 (vfat) partitions are unable to store anything about permissions or ownership. ( Which doesn't prevent me from using them!) That is what creates this problem:

Because the vfat partition knowing nill about ownership is mounted on a Linux ( or UNIX or BSD..) system, the path it is mounted on substitutes those missing permissions and ownerships by root- ownership and permissions. Otherwise said, root ownership is automatically assumed. This is correct default action by your Linux box, and there are bloody good reasons for it doing so.

Therefore, you must change the assumed permissions, and that has to be done as root. But to make your Linux system let you do that, the vfat partition must be unmounted first! Then with the unmounted vfat partition, you can change the assumed permissions, and best of all you can make a link pointing to that vfat partition from your user-desktop. Once you reboot your box, the partitions will be mounted again and the permissions may revert back to root. That is no problem though, because you as "username" will continue having write and read access to that partition in spite of that.

I have a HD with NTFS. Is it possible to partition it, so I have some FAT32 in there? how?
Thanks for your link. I have tried to install FUSE, but get the following error

I'm a newbie! so I dont exactly know what they mean by

"If this produces an error, please read on.

The configure script will try to guess the location of the kernel source. In case this fails, it may be specified using the --with-kernel parameter. Building the kernel module needs a configured kernel source tree matching the running kernel. If you build your own kernel this is no problem. On the other hand if a precompiled kernel is used, the kernel headers used by the FUSE build process must first be prepared. There are two possibilities:

1. A package containing the kernel headers for the kernel binary is available in the distribution (e.g. on Debian it's the kernel-headers-X.Y.Z package for kernel-image-X.Y.Z)
2. The kernel source must be prepared:

o Extract the kernel source to some directory
o Copy the running kernel's config (usually found in /boot/config-X.Y.Z) to .config at the top of the source tree
o Run make prepare"

i agree that by default only root has ownership of vfat/ntfs partitions and normal users have read only permission. But if you wanna give read/write access to all users then no need to change ownership or linking etc. set umask=0 in fstab file. thats it.... in case, you wanna change ownership also, add UID and GID of user too......

you can use Partitioner in YAST for creating partitions. or GParted.

I have tried to install FUSE, but get the following error

you must be logged in as root to install it.


i suggest you to go for FAT32 partitions coz it will save you from a lot of troubles and its very easy to repartition the disk through SuSe's partitioner or GParted.
