hello all,

I've been trying to install a fresh copy of slackware 10.2 on my system that used to run it with out a problem. I deceided to try to run a differnt distro and wasnt as happy with it.

so i tried installing and somehow i have corrupt cd's. so i d/l new copies, and install. crc errors, and a hole bunch more. it seemed like every reboot was a differnt error. the latest being invalid tree.

ive downloaded this off of slackware about 5 or 6 times, ran the check sums and what not and was told they were all okay. so why is this not working still? is it my computer? am i checking the md5's wrong, i'm using md5summer for windows xp. they claim to be compatable with linux.

and to write the iso to cd im using iso recorder.

if im fucking this up somehow can you let me know, i just want to install my fileserver back, and i'm getting beyond frustrated here.

thanks,

The first thing you should do is to determine, beyond a doubt, that your Slackware CD's are perfect.

You can do this by following the instructions on this tutorial:

Take your time and understand what he's saying, and let us know how it goes.

Good Luck!

It sounds like bad media. This can be caused by bad CDs or a failing CDROM drive. Have you a CD lens cleaner around? Might want to run that through the drive.

Or maybe you are trying to burn them too fast. Regardless of your CD's top rated speed, just burn at a slow speed, maybe 8X or 16X. It's a one time thing so if it takes 5 or 6 minutes instead of 2 or 3, no big deal

I have had similar problems in the past which was caused by faulty hardware on my system, not faulty CDs. Thus I recommend that once you have verified beyond doubt that the media you downloaded from Slackware.com and burned on slow speed is OK, do a full system check of your hardware.

1-2 years ago I bought a second-hand server off eBay which ran SuSE Linux just fine, but kept giving me checksum errors during the install on Slackware (on random locations). After a couple of seriously frustrating days, I identified the problem as being the system RAM - it had 2 different RAM chips of 256MB each, one a bit faster than the other, and this caused the Slackware kernel some serious problems... Once I replaced one of the RAM chips, the system installed fine, and has to this date an uptime of 252 days (would've been longer if it wasn't for a power failure last summer)

Thanks for all the replies, there's a couple of things i'm going to try.

I did drop the speed when i wrote teh cd. i think i have a 24speed writer. so i dropped it down to 12.

I thought it was a ram issue, cuase i had problems with that before, so i took out the questionable ram and still had the sam problems.

Ill go thru checking my media again, its gotta be fine, but ill do it again to be sure.

i have an extra cd rom, thats one of my ideas of whats wrong, but thats more of just a guess.

thanks for all the suggestions, ill let you know what happens.

Hi,

Just a few suggestions!

If you are over-clocking then step back your speed. OC can cause
I/O issues with peripherals. Clocking issue with RAM can be intermittent.

Another problem can be media, I've notice lately a lot of the cheap on-sale cd-r media causes compatibility issues.

You could be having a compliance problem between your CDR and CDROM. That is if your boot cdrom is different from your cdr. Meaning if you burn your cd on one drive and move to another to do the read. The drive alignment can be a problem. Usually this doesn't occur to often. The optics will either pick the signal or not.

Run a check on your hdd.

Did you do any firmware upgrade to you cdrom?
