Subject: Partition Table corrupted
Date: Wed, 07 Mar 2001 22:00:18 -0800
Just have some urgent questions to ask: is it at all possible to recover
some of my data if my partition table is lost?
The situation is as follows: I installed win95 long time ago, and
install Linux recently. The partition layout is:
win_c | win_d | swap | Linux | hypernation for laptop |
I have backed up data in the windows partition (c: and d:), and then I
installed win98, change c: and d: to FAT32, and then I decided to install
win95 instead of win98, so I format the c: and d: and reboot the computer
with DOS6.2, and it said the computer is not configured to install DOS 6.2
( I think it's because it's in FAT32 ), so it asked to configure c: to be
able to install DOS 6.2, and then when I reboot the computer, the
partition table is lost. I booted the computer with DOS and try to see the
partition with fdisk and there is only one DOS partition of about 2G. I tried
using the Linux boot disk created by
mkbootdisk but 'kernel panic' appear. I'm just wondering if it's at all
possible
to recover the data in the Linux partition, even if it's a painful way.
Let me know your answer asap,
Thanks,
regards,
Sau

Here's a script that will do it...I'm somewhat new to shell scripting,
if there's a better way, it would be good to know:
#!/bin/ksh
for ea in `ls /export/home`
do
if [ -d $ea/.netscape/cache ]; then
rm -rf $ea/.netscape/cache/*
fi
done

Correction in the above script...
Most Linux distros, by default (iirc, don't have /bin/ksh
installed...just use /bin/sh

It's a safety feature to keep people from trying to telnet in using the
root account. Since telnet is plain text transmission, it is quite
simple to snoop passwords. In light of this, I would recommend using
ssh rather than telnet.

That's your problem then. Your CD contains a copy of the ISO file rather
than being produced from the ISO file.
The process of burning a CD involves two stages - first you create
an image of the CD containing all the files you want on it, then you
burn that image to CD. You've done both stages when you really only
wanted to do the second one. The ISO file is a pre-prepared CD image
which just wants burning to CD.
>Something tells me that I need to "work" the ISO as it is being put onto the

No - you need to prevent your CD burning software from "working" the ISO
as it is written to CD. Look for an option involving pre-prepared images,
(possibly referred to as raw images). If your CD burning software doesn't
have such an option you'll need to get some better software.

What's the problem with copying the CD contents to a normal directory tree,
(cp -a /mnt/cdrom /mnt/cdrom_backup)
changing the file you want to change, and recreate an image?
It's not that difficult, no need for other software for a fairly
simple task like this.

What is hda8?
You don't have one, right?
Can you make that partitiontable, using fdisk?

you're running it during install,
after you installed everything, use that floppy again to boot, and
specify "linux root=/dev/hda7" at the lilo prompt.
Then install the new kernel, update lilo.conf, rerun `/sbin/lilo -v`
and reboot, from HDD now, using the new kernel you just installed.
Don't try to boot with the old kernel

Date: Thu, 08 Mar 2001 07:53:35 GMT
Unfortunately I don't have NERO on this win98 machine, but I'll try to help you
anyways.
Consider the ISO file sorta like a ZIP file ( without compression). The ISO
has all the directories and files needed to install Suse on you computer.
Consider your CD burning software sorta like winzip. However, your Nero
software won't allow you to extract the ISO file to your hard drive, ( at least
not that I know of. IF anyone knows that nero can do this please correct me. )
Nero should however take that ISO file and open it up to your blank cdr or cdrw
disk by burning it to CD. Go into Nero, look in your drop down menu's ( and
possible sub menus ) for an option called "create disk from image file". They
may phrase it differently. Also if I remember Nero correctly ( it's on my office
server but I haven't seen it in months) there's a list or CD making options on
the left column of the screen. There may be an option there to make a cd from an
ISO file. If you can find that option point Nero to your ISO image and click
burn.
I hope this helps somewhat. Unfortunately I won't be at the office anytime
soon or I would try this myself and give you a step by step. Perhaps some in
these news groups that uses Nero could write a mini-How-To?

Why should those perms change in case some user logs in, sure you could
write something in /etc/profile that changes those perms in case someone
logs on, but what would be the advantage of doing something like this?
man mount
describes how to enable mounting of a cdrom for users.
grep user /etc/fstab
/dev/cdrom /cdrom iso9660 ro,user,noauto,unhide 0 0
/dev/scd1 /cdrom-b iso9660 ro,noauto,user 0 0

That's the same I do, except I use different fonts, but overriding
document-specific fonts seems to be the best way to actualy read some sites,
where the designers are to dump, to test the pages with something different than
IE.
Sometimes, I write a polite email to the webmaster, telling them that it's
almost
impossible to read their site with NS/Linux, but that gets boring...:-(
