Unless you're using LVM (Logical Volume Manager) I fear there is no
possibility.
However, you can mount the reclaimed space where you like.

Subject: smartlink linmodem driver problem
Date: Sun, 27 May 2001 17:39:58 +0200
Hello!
To my surprise, I finally found a linmodem driver for my aztech
mr-2800w internal modem at ftp.aztech.com (dated may 9 2001)!
It's called MR_CNR2800UW_2216.zip.
This seemed to be great news, for so far I had been unable to use my
modem riser under linux (while the smartlink as well as the aztech
drivers for this modem card work fine under windows). linmodems.org
still lists my modem as unsupported, by the way.
I looked through the "readme.txt" and found that it requires (among
others a VIA686 mainboard, which I do have), a kernel 2.2.16 or higher
(I have 2.4.3) and for instance a suse 6.4 distribution (that's what
my most recent system is based upon).
I followed the instructions to install the drivers (kernel modules
etc.), but unfortunately, I got unresolved symbols in all of the
linmodem modules (sl*.o).
So I decided on trying a 2.2.16 kernel (which the readme.txt mentions
as the system where the rpms were tested and worked!).
But although I now had a 2.2.16 kernel, a suse 6.4 system and a VIA686
mainboard, there was no success! The modules still had unresolved
symbols and could not be loaded!
I am not very optimistic that many people might be able to answer me,
but perhaps someone already knows about these new drivers
(unfortunately binary-only, of course), the problem with the
unresolved symbols etc. and may have some helpful idea?
Many thanks
Manfred

Yep. USB won't work for me. I need to communicate with
several RS-232 devices ranging from 9600bps to 115.2kbps.
Just a bunch of command/status messaging between some
custom software and some navigation sensors in a NASA lab.

A usual trick for many copy-protection schemes is to format one sector with
weird size and / or address. It seems to me that you're overwriting the
sectors 1 to 5 when writing the oversize sector. There is only 5 * 512 bytes
= 2560 bytes (+ gaps and headers) of data space for the 8 kbyte sector.
You should probably avoid writing the extra-size sector, if possible. Also,
it seems to me unnecessary to format the sectors 13 to 17.

Well I wouldn't think so, but I didn't know if Linux had some builtin
partition utility that would do it. I don't think Partition Magic will
will it?

Subject: home web/file server specs?
Date: Sun, 27 May 2001 17:03:17 GMT
I am fairly new to linux but quickly becoming a total convert... Could
someone please give me some advice on what type of hardware I would need for
a home based web/file/ftp server? It would probably have an avg of 3 users
from the lan side with a rare max of 8 or so users and maybe 5 - 10 users
accessing it from the outside at any given time. I would like it to be able
to handle cgi without too much fuss as well. Should I set up different
machines to accomplish these tasks? What kind of lag would people
experience if someone was using the server as a workstation?
Thanks for any and all help :).

Subject: tape backup malfunction
Date: Sun, 27 May 2001 17:10:17 GMT
I have an HP Colorado tape backup drive, linux 2.2.9. Before I was able to
access any block on the tape just by issuing the command "mt -f /dev/nht0
seek <block no.>". Now when I issue that command, the tape only advances to
block no. 1. The tape will only advance one block at a time if I use a
command such as eof. The command bsf will always rewind to block 0.
Previously written starting blocks are inaccessible and therefore I can't
access the data that I've already backed up to the tape.
Has the tape been erased? Or are these read errors? I've just tried
retensioning the tape a few times, with no effect. And I haven't erased the
tape on my own. Does the drive need to be cleaned, or is it defective? I'd
appreciate any advice offered. The security of my data is compromised.

Cleaning the drive is definitely worth a shot. I've had tape drives on openVMS
boxes that refused to work until the cleaning cartridge was passed through.

perhaps not MS-DOS. but then you could honestly argue that it is not

dump is not a sufficient solution either. linus had a few comments
about this on linux-kernel about a month ago. it seems that the only
way to get a clean snapshot of the disk partition is to unmount it
first and then save. this is especially true of the journalling
filesystems.

Modems do not need drivers unless it is a winmodem. You can try at linmodem.org,

I've got a machine that does pretty much that. It's a Pentium Pro 180
with 32MB RAM and 2 x 2GB SCSI disks. Most of the time the processor
is running at about 96% idle so a PPro 180 is actually overkill for
this ;-) It _could_ do with more RAM though but since it's a Compaq
Proliant 800 and takes weird ECC EDO DIMMs that no-one stocks it's not
likely to get any in a hurry.

Date: Sun, 27 May 2001 22:36:05 +0200
Hi,
ok i have a very very big problem :
(i can say i am desparate)
i've tryied to install rh 7.1 for god know how many
tomes and without success:
the installation gets stacked on :
"transferring install image to hard drive"
i've tryied all available option with disk druid, fdisk
and automatic partitioning
but nothing nothing helps.....
still the same result
when at the point where the installation hangs
i did ctrl+alt+f3 i saw that that there was a problem
to create the partitions:
/boot - cannot create not enough space
/ the same
....
....
....
when i tryied to install for the second time
it did the partitions but
gave the error:
hdd disk error something,
can't read block.....
and this error keeps running down the screen for each block
(the installation hangs with
"transferring install image to hard drive" )
(the install cd is perfectly ok)
then it writes :
there was a problem maybe
because you haven't enough space....
but that's boolshit
i have 14GB just for linux
i have two disks:
primary 20GB
primary slave 30GB : (14GB for linux)
when i had just one 20GB the installation was the same
hanged on the same point
i just don't know what to do....
it seems like hardware problem
but windows works ok...
and furthermore Mandrake 8.0 gets installed without
a problem
but hangs every 2-3 hours but that's i believe
an IRQ problem
i somehow have 4 devices on the same IRQ.....
my configuration :
AMD 900 MHZ
MBoard chaintech 7AJA with AC'97 sound on-board
256 MB memory
two disks...
* by the way when i tryied to install RH 7.0
i've also was without luck...
after partitioning the install gets reboot and doesn't
actually did the partitioning (as i checked later)
**ok if anybody knows what might that be
and any suggestions i would be glad to hear.....
it driving me crazy.....
