Hi, Ray:

I am using Slackware v9.1, kernel 2.4.22, and a
"CRW-5224A, ATAPI CD/DVD-ROM drive"

'cdrecord' can 'burn' to ATAPI devices with SCSI emulation.

If append="hdc=ide-scsi" is parsed in lilo.conf during boot
( and you are using lilo as the boot loader
and /dev/hdc is your CDROM-RW device ;-)
then applications that default to using SCSI devices will use
the ATAPI device. Here is a script that I use to burn data to
my ATAPI CDROM-RW device:

#!/bin/bash
#
# /usr/local/bin/burncd.sh
#

cat /usr/local/bin/burncd.sh

echo ""
echo " First argument is <$1>."
echo "Second argument is <$2>."
echo ""

eject -t ; close the CDROM tray

if [ -n $1 ] ; then
if [ -n $2 ] ; then
cdrecord -v dev=0,0,0 fs=64M speed=$2 driveropts=burnproof $1
else
echo "Second argument is burn speed [1 - 52] and must not be null."
fi
else
echo ""
echo "First argument is filename.ext and must not be null."
echo ""
fi
mount /mnt/cdrom && ls -l /mnt/cdrom && umount /mnt/cdrom
echo $1
eject

HTH, Chuck

Re: Backup up Linux fileserver via Maxtor External Hard Drive

Second, what issues do we need to resolve in order for a. the Linux box to read the drive, and b. formatting the unformatted external drive to work with the Linux box? Eve -- I waited a bit before replying, in the hope that someone with more specific knowledge than I can offer would turn up. My own experience with USB drives is limited to flash drives (those little keychain thingies). But I suspect that the issues for these USB hard disks are the same, so I'll tell you what I know in the hope that you will find it helpful. First, to mount and read the drive, you need a few things set in your kernel. (This is for 2.4.x kernels; if you use 2.6.x, the details may differ a bit.) USB Storage -> Support for USB -> USB mass storage support needs to be enabled (in kernel or loaded as a module) In this area, you probably also want to enable USB Storage -> Support for USB ->Preliminary USB device filesystem USB drives are mounted as scsi drives, so basic scsi drive support needs to me provided, either in kernel or loaded as a set of modules (two, as I recall). Abd you need the /dev pseudofile entries for scsi devices, probably just /dev/sda and /dev/sda* an appropriate filesystem driver needs to be loaded, in the kernel or as a module; ext2 works fine. Second, once you have all that set up, you should be able to use the usual tools to set up your USB drive. It will (probably; I don't know your setup) show up as /dev/sda, so you can fdisk that device to set up your partitions, then mkfs.ext2 whatever partitions you choose to set up, then use whatever you are used to using (cp, tar, whatever) to do the actual backups. Third, one thing Linux is never very smart about is noticing when mounted filesystems are removed. You'll want to be careful to umount any filesystems on this drive before you disconnect it. (The USB stuff itself is fine about noticing the connection and disconnection of USB devices.) And ... this was probably obvious ... you need to umount the partitions after you connect the device. Last, the only likely issue your use of USB 1.1 will raise is speed of packups. If that proves to be an issue for you, and your server is an i86 system, you might want to spend the US$10 or so for a PCI card that provides USB 2.0. As I said at the outset, I haven't actually used these drives myself, so I'm extrapolating hee from my experiences with USB flash. If I've gotten some details wrong, I do hope that someone will spot them and post a correction. -- No virus found in this outgoing message. Checked by AVG Anti-Virus.

Sorry, Chuck. Bad writing on my part. When I wrote the above, I meant to be referring to writing to atapi devices in native mode. I use scsi emulation here in pretty much the same way you do and have done so for years. I was surprised (and still am) that Peter has an ATAPI CD burner running at all under 2.4.x, unless he is already using SCSI emulation (relevant since most of the feedback he got was about using SCSI emularion ... if he's already doing that, it won't help him). -- No virus found in this outgoing message.

Thanks, Eve Hi, Eve: I recently purchased a USB interface device that accepts a 2.5" hard drive. It is USB 2.0 & 1.1 compatible, it just runs slower at v1.1 according to the documentation. I inserted one of my linux laptop driver and plugged it into my USB port of a Slackware v9.1, kernel 2.4.22, workstation and 'tail /var/log/messages' reported: Dec 29 05:18:21 server kernel: hub.c: new USB device 00:10.3-6, assigned address 3 Dec 29 05:18:22 server kernel: scsi2 : SCSI emulation for USB Mass Storage devices Dec 29 05:18:35 server kernel: sdb: sdb1 sdb2 Dec 29 05:18:38 server usb.agent[1535]: missing kernel or user mode driver usb-storage I am not sure what the last line meant but, knowing that my 1st partition is swap and the 2nd the working partition, I: mount /dev/sdb2 /mnt/hd mounts the filesystem at /mnt/hd :-) 'lsmod' |grep -i usb shows that usb-storage and usbcore are installed. As Ray mentioned, if your new drive is unpartitioned and/or unformatted; I assume that you can use 'fdisk' to partition and mkfs.???? to create a filesystem on it.

" To create a partion, run fdisk and partion the correct device. If you wish to format the drive with a file system, you can use: mke2fs /dev/hdXX (sdXX for scsi) for an ext2 partition mke2fs -j /dev/hdXX for ext3 partition mkresierfs /dev/hdXX for a reiser3 partion I personally use an ext2 on my boot partion, and a reiser 3 for everything else linux. One more thing, the partitions must have a file system installed in order for you to mount them.
