Novell SLES10, 64 bit install media

[Dan Martin]

Hi All,

I'm having trouble creating the first install CD for
SLES10, 64 bit.

CDs 2 thru 4 are fine. 
md5sum /dev/cdrom   returns the correct sum for CD2 thru CD4.

After downloading CD1,
md5sum SLES-10-AMD64-EM64T-CD1.iso
returns the correct sum.

Only after creating the CD do I have problems--
md5sum /dev/cdrom
md5sum: /dev/cdrom: Input/output error

Suse's media check from the install menu passes for CDs
2 thru 4, but fails reading sector 346,432 on CD1.

I've tried 3 different CD writers, 2 under windows and
one on Linux.  The Windows program reports a failure on
CD1 (but creates CD2-4 ok).  The CDRW on linux finishes
CD1 without reporting an error, but the md5sum is wrong.
I'm not familiar with the details and options that I might
try on the CD writing programs.

CD1 is larger than the others, so I'm guessing that might
contribute to the problem.  I dd'd the contents of CD1
back to a disk file, and dd created a disk file of
693221376 bytes.  It should be
709601280 bytes (676.7 MB)

Any advice on how to write the CD?

Many thanks,
Dan Martin
