I downloaded Simply Mepis because I lost my install CD, confirmed the md5 sum.
I burnt it to a XLogic blank CD, silver colour, wouldn't boot. Some cd's would error on burning and become coasters.
Burnt to a TDK gold CD still the same problem with the cd not being recognised.
I finally went and bought a pack of 50 HP branded blank cd's at The Warehouse for $20, and have yet to have a problem with even one of them.
Mepis really rocks as a distribution, the debian apt-get is rock solid compared to Mandrake/Red Hat rpm way of doing things.

sounds like you're out of luck.Did you install this working system using the very same CDROM drive that you are using with dd ?
as a last resort, you could try mounting the cd, copying recursivley the contents to a temporary directory then using mkisofs to make the iso.
fwiw. i've only ever had this problem on burnt disks. they appear fine in some cd devices and have difficulties in others.

Sluggers,
I've always been able to make a copy of a cd or floppy onto the hard disk by using dd. I.E
dd if=/dev/cdrom of=myimage.iso
I've been trying to do this with some FC3 cd's but after copying about 630Mb the process starts throwing messages up onto the console about bad block read's. This goes on for several minutes and trying to kill the dd process doesn't seem to work, though it eventually dies. When I mount the resulting .iso images with -o loop they appear ok and I can see all the directories and file names but if I try to copy an .rpm from the mounted file system it's no good. So obviously the cd's are dud right!
BUT! I've just done an install of a working system from the very same CD's
and even ran through the little check media utility at the start which said
the CD's were OK.
Your problem may be related to media/hardware quality rather than data corruption.
The drive you are using to do the dd with may simply "not like" that cd media.
Just last night I was having problems reading my Q3/UrbanTerror CD using both a Sony & a Mitsubishi CDROM drive.
However the same disk worked perfectly fine in an Optorite CDROM.
I've since copied that to another brand CD (TDK) and now all my workstations & drives are happy and I can play UrT3.1 again :)
