Re: Disk 2 and 3 Corupt



Ok. I gave up on the Disks and went for the DVD ISO.

Using B's Recorder I created a bootable disk from the image.

The contents of the disk are:
BOOTCTG.BIN  BOOTIMG.BIN  FC-5-i386-DVD.iso

The sha1sum of the ISO on the disk looks good:

$ sha1sum FC-5-i386-DVD.iso
ed9a852cf77250c3ae111c621d350af5c0b0a29b *FC-5-i386-DVD.iso

When I put the disk in and try and boot from it I am taken to a grub command prompt. No istallation.

I have set my bios to boot from a CD. Does this indicate a problem with the disk?

Thanks,

Luke

I don't image I am the only person to bring this up, but can someone point me to a place where I can download discs 2 and 3 for the Fedora Core that do
not contain corrupt packages?

I have downloaded both from here:

ftp://ftp.uninett.no/pub/linux/Fedora/core/5/i386//iso/

I have tried downloading and burning to disk twice. Both times disk 2 and 3 were currupt (i.e.: Did not pass the integrity test, when I tried to install
anyway, was unable to read from disk 2).

I use the kernel.org archives.  Try this link:

http://mirrors.kernel.org/fedora/core/5/i386/iso/

and download away.  Also look carefully at the content of the SHA1SUM
file.  After you download the .iso images, run:

sha1sum name-of-iso-file

The number that spits out SHOULD MATCH EXACTLY what the SHA1SUM file
says.  If not, you have a bad download.  If the SHA1 sums match, the
.iso file is clean, and you're having issues burning them to CDs.

NOTE: CD2 and CD3 of the FC5 distribution REALLY fill up a CD.  Make
sure you're using name brand 700MB CDRs (I lean towards Memorex and
TDK) and that you do NOT burn them at maximum speed.  For example, if
you have a CDR drive that can burn at 48x, try burning at 24x or even
12x:

cdrecord dev=ATA:1,0,0 speed=24 name-of-iso.iso
cdrecord dev=ATA:1,0,0 speed=12 name-of-iso.iso

The reason is: CDs are written from the center of the disc out toward
the edge in a long, spiral track (like an old vinyl LP record, but in
reverse).  The faster the disc spins (to give you that higher read or
burn rate), the more likely the disc will "flutter" and the problem gets
worse the farther from the center you are.  Keeping the speed down will
reduce the flutter and give you a better chance at getting a good burn.
