11.2 Burning and Install Issues (checksum mismatch, insert CD1, unable to recognize, etc)

Summary:
I have burned the .iso six different times. Some of the burns resulted in errors, and those that did not were unable to complete an install on another machine.

Details:
I’m trying to install 32-bit 11.2 on an old eMachines laptop (see below).

I have burned the image onto six different DVDs:

  1. Burned the DVD using Win 7’s ‘Windows Disc Image Burner’ and completed without error. When trying to install on laptop I repeatedly received errors asking for me to insert a “CD 1.” After rebooting and checking the media I received the blunt “This CD-ROM is broken.” (sorry, I didn’t record the exact error #)
  2. I then burned, using the same program, another copy of the .iso that I had earlier downloaded via bittorrent (downloaded direct and bittorent at the same time, forgot to cancel the slower one). I didn’t remember to check “verify disc after burning,” so can’t confirm that it had no errors. Laptop did not recognize and would not boot from CD.
  3. Used Alcohol 120% to burn bittorrent .iso. Burned using slowest x6 write speed. No errors. Again the laptop was unable to recognize that a bootable disc was in the drive (though it sounded like it was trying).
  4. Used Alchol 120% to burn direct download .iso. Same problem as above.
  5. Uninstalled Alcohol 120%. Downloaded third .iso from mirrored server, and tried to burn using Win 7 image burner. Received error code “0XC0AA0301.” Decided to upgrade firmware.
  6. Upgraded firmware on DVD-writer. Burned mirrored .iso download using Win7 burner with no errors. Laptop was able to boot, but while checking media received “Error reading sector 772838. This CD-ROM is broken.”

Attempted solutions / other info:
I upgraded my firmware for the DVD-RW drive (don’t believe Windows when it says all of your drivers are up-to-date hah).

And after doing some reading, I came across MD5 checksums. And throughout the entire above process tried to compare the MD5 contents of each .iso to that found on the download page. I was using TSoft’s MD5 Check Utility V2.31. I kept being told that they didn’t match, so initially, I assumed I was doing something wrong (I mean, how can THREE downloads not work!?!).

MD5 checksum from opensuse.org: 2B86E43ECE65132BD96465714439C9A4

MD5 checksum from all three of my 11.2 .iso:
CB28648F43520891DC7CF8C6E78FBADF

Looking for:
Answers!

…but seriously has:

  1. Anyone seen anything like this before?
  2. Where can I find more information about checksums? e.g. What do I do once I know that there is a no-match? What else are they good for? etc.

The desktop that I am using to download and burn the openSUSE .iso:

  • OS: Windows 7 Home Premium 64-bit
  • system info: Intel i7-860 installed on a MSI MS-7586
  • BIOS: default BIOS
  • RAM: 4 GB
  • DVD/CD-ROM Drive: Lite-On DVDRW SHW-160P6S ATA Device
  • Display: GeForce GTX 275

The laptop that I am attempting to install .iso on:

  • eMachines M5305
  • OS: Ubuntu 9.10
  • system info: AMD Athlon XP-M 1.67 GHz
  • RAM: 1 GB
  • DVD/CD-ROM: original CD-RW/DVD-ROM combo (8x DVD read)
  • Display: ATI Radeon IGP320M

Thanks, guys! (and girls)

The checksum of the downloaded iso should be exactly the same as the corresponding md5sum on the website. If not, the download is corrupted and the burnt media will never be OK. Let the torrent program do a check on the iso, redownload missing chuncks, check again until 100% OK.

The strange thing is your supposed official checksum isn’t listed anywhere official that I can find. Here are the checksums I have. I don’t have all the images. From my archive, GNOME CDs are missing as well as the add-on languages, which you and I don’t need.

And when I did a search on the checksum that T-Soft gave you, it only matched another posting late last year by somebody who also failed. He gave up and didn’t come back.

So a few things:

Exactly which image are you trying to get? CD or DVD? GNOME or KDE? i686 or x86_64?

I would not trust T-Soft’s program at all. md5deep I have used with success.

What kind of filesystem are you downloading to? FAT32 has a 4GB limit.

Do you have any reasonable way to use a linux system for downloading, burning and checking?

I ask this because I have now followed a number of threads that get quite long,but finish with the OP using linux for this process.

edit, Ijust noticed ken_yap’s post and agree, these are good points.

Thanks for the replies.

So, yeah, when I run TSoft’s program on the .md5 file it pulls up what I posted above, but when I just open up the file in .txt I get 295d713314a30ad017948f0d542c6d92.

So the answer to your first question: I’m trying to get openSUSE-11.2-DVD-i586.iso.

I downloaded md5deep, but I have no idea how to use it quite frankly. I tried a few tricks, but found it was faster to Google and download another than read a help file on a text based program.

And, file system? CDFS(?)

I’ll try using a live-boot on my desktop and try burning another copy later today and will update on its status.

Ah, so that’s what the problem is. It’s just a text file. You run TSoft’s checker on the .iso file, not the .md5 file.

Try running TSoft again, but this time on openSUSE-11.2-DVD-i586.iso

If the answer is 295d713314a30ad017948f0d542c6d92 you have a good download. If not I suggest using bittorrent to fix up the errors in the file you have. Do not proceed to burning until TSoft gives you exactly 295d713314a30ad017948f0d542c6d92.

SOLVED

Sorry that I did not get back to the forums sooner.

I ended up just installing Ubuntu 9.10 on the desktop (needed to format the thing anyways).

Strangely enough the very first download was perfect, matched the checksum, burned perfectly, cleared the check media test, and now OpenSUSE is running perfectly on an old laptop.

I have no idea why it wasn’t working before. I WAS doing everything everyone said, using torrents, etc. My only explanation is maybe 64-bit Windows 7 screws up trying to download/burn 32-bit OpenSUSE?! But no real idea of why it was doing what it was.

Thanks for your help!

Hi,

This is Jessica here from Canada. As I have seen your issues because that’s what the problem is. It’s just a text file. You run TSoft’s checker on the .iso file, not the .md5 file.

Try running TSoft again, but this time on openSUSE-11.2-DVD-i586.iso

If the answer is 295d713314a30ad017948f0d542c6d92 you have a good download. If not I suggest using bittorrent to fix up the errors in the file you have. Do not proceed to burning until TSoft gives you exactly 295d713314a30ad017948f0d542c6d92.
Thanks
Jessica

Hello Jessica,

That was an unrelated issue. The .isos themselves indeed resulted in checksums not equal to the standard provided by OpenSUSE. Seemed to occur with any download. But, again, no longer an issue since I formated and got rid of the 64-bit Win7 sys
