cant access windows partition with mnt or editing fstab


on my dual boot with win98 and fc1, i mounted the logical drives in the extended dos partitions - the data was accessible for one drive but not the others which appeared empty.

once i mounted those drives though, windows refused to boot. so i tried to reinstall windows on c drive which didnt work, quoting the same 'unexpected error' as before. and now i cant access the extended drive at all. 'mount' seems to happen but there no data appears. i also tried editing fstab like i did before but that doesnt work either.

what i want to do is back up my extended dos drive on cd and reformat the hd, lose windows for good and install fc3 and mandrake.

any advice on how i can access the dos drives and back them up?

Get Knoppix and look whether it can see the partitions. Use "partimage" from the Knoppix CD to save your data on CD and proceed from there...

tried knoppix

checked the md5sum but am getting messages like:

I/O error: dev 0b:01, sector xx
cloop: read error at pos xx in file /cdrom/knoppix/knoppix, xx files lost
error -3 (also error -5) uncompressing block...

finally it gets to
executing /etc/init.d/xsession start
starting x11....
retrying with server XFree86 (vesa)..
retrying with server XFree86 (fbdev)...
error: no suitable x-server found for your card
and then just halts

any pointers on what this means and how it can be fixed?

will go look at knoppix.net in the meanwhile...

Yeah, you either downloaded the Knoppix-iso with bit-errors or you burnt with errors (from a CD?). For the first you would have a wrong md5sum (but I guess you checked, your posting is not entirely clear to me).

For the second problem (burning error-free also from an other CD) try this: http://www.troubleshooters.com/linux/coasterless.htm

A set of parameters that you add at the initial 'boot:' prompt
to enable such things as 2.6 kernel, custom config of hardware, etc..

Try the first four of these:

noapic noagp noapm nodma nomce nofirewire nopcmcia noscsi noswap nousb nosmp noaudio

in additive sequence, i.e.

noapic
noapic noagp
noapic noagp noapm
noapic noagp noapm nodma

until it hopefully (after the first attempt? ) works.

knoppix26 works right, partimage works also, thanks

but,
how do i copy selected directories and not the whole partition?
if i try to write files/directories from the mounted partitions to cd using k3b, the files appear much bigger (on k3b) than they really are - why?
could use cdrecord but there are lots of files of different filetypes.
also, i cant write to any partition, including the linux one, so cant copy files into there either.
tried mounting with -o rw but it doesnt work.
what am i missing?

Try mounting the Linux partitions with
Code:
mount -o remount,rw

 check for the exact syntax with

man mount
or umount them first.

You can use cp recursively to copy directories and their subdirectories incuding the files. Or use Konqueror. I have no idea why K3b shows too much space, never had that problem.
