dd: reading '/dev/cdrom': Input/output error
It sounds like there is a problem reading the device. It could be a faulty disk, or maybe you mounted the disk? I have never tested this, but I think it's possible that mounting the CD might prevent a direct read.

bear with me on this one ...
launched a menu item called system stats
it put a stats.txt file in /home/dsl
opened the file, listing follows below
there may be a conflict with the cdrom as opposed to a problem ith the cdrom
running dsl-4.2.3, booting from floppy to usb
usb created with menu item USB-HDD, which created sda1 and sda2 that holds the boot image
boot:  dsl fromusb (from floppy)
boot:  ds fromhd=/dev/sda2  (from livecd)
stats.txt lists /dev/sda2 as /cdrom
?is this causing dd to fail?

ps, ?do you know where the shell script is located that creates (1) USB-HDD and (2) stats.txt so that i can view them?

No, /cdrom is just a DSL frugal convention, and is a just a mount point... it has nothing to do with /dev/cdrom

You can search the menu files, i.e. with `grep -i "\(usb\|stats\)" ~/.fluxbox/menu`

What's the output of that cdrecord command?
