I have this program that comes in multiple cd's. Its proper installation needs to create a multi gbyte data base by installing the cd's (1 file each) one after the other. Problem is when it's almost done with the second one (before it reaches the point to ask for the third one) there is this message that reports a checksum error.
Can it be anything else than a faulty cd?
And if it is caused by a faulty cd, could it be the first one instead of the second that is faulty?????
Please help!
Because each disk you're loading could hold a maximum of 700Mb, and the amount of RAM you're running could affect that kind of thing, especially if you have a limited page file, even though you're running 256Mb of RAM, you don't have 256Mb of RAM available to you, other programs are using resources in the background, just for your computer to operate, Win9X systems operate wonderfully on 512Mb of RAM, but no more than 512Mb or trouble arises in the other direction.
My total suggestion is to increase your RAM to 512Mb to avoid these kind of problems in the future, but a workaround would be to use the Task Manager and End Task on every running program except,(Explorer and Systray because if you end task on them your computer will shut down), and make sure you haven't limited the size of your page file.
Each one of those discs does have one file a little bit more than 600 mb in size. But the procedure to rebuilt the library does it on the HD, i don't see how it would need so much ram at a time, although you could still have a point if it tries to reconstruct a single file that exceeds the available ram (but it's not files that it reconstructs; it's one continuous, big chunk of data that it tries to reassemble)
I don't have anything running in the background.
If ram is the issue shouldn't it have occured during the instalation of the first cd?
Also, if that is the case, shouldn't i get a message regarding ram instead of one that mentions the cd?
By the way, what's the max recommended ram for 98se and xp pro?
The bottomline here is that the Checksum Error means that from the time you put the CD disk in the CDROM drive to the time the files were accounted for on the hardrive something is missing or corrupted.
There are many things that could cause this to happen, but it usually involves a process of elimination to track down the problem, its not simply heres your problem, even OP/SYS's handle the situation differently, but you haven't even specified what OP/SYS you're running, and you seem to want to analyse the advice you're getting instead of using it. So heres just a few things of what could possibly be wrong:
Bad scratch on CD,
Corrupted file on CD itself,
Dirty CDROM lens,
Faulty CDROM drive,
CDROM drivers need updating,
RAM errors,
Power glitch,
Bad sectors of the hardrive,
Sometimes Checksum Errors are RAM related.
How could that be???
You put the CD in the CDROM drive, the CDROM drive starts reading the CD and sending the information to the hardrive, but it goes through the CPU and RAM working together to send the information to the hardrive, If the CD itself is good, and the CDROM drive is functioning properly, but the files are corrupted by the time they arrive at the hardrive, 90% of the time memory errors are the problem.
Use Memtest86 to check your RAM for errors, you can get it here<A HREF="http://www.bootdisk.com" target="_new">http://www.bootdisk.com</A>
Also you can disable the read ahead feature on the CDROM drive.
Run a thorough Scandisk to check for bad sectors on the Hardrive.
Now if you're going to disregard my attempts to try and help you, you can resolve this issue yourself,<A HREF="http://support.microsoft.com/search/default.aspx?InCC_hdn=true&Catalog=LCID=1033&CDID=EN-US-KB&PRODLISTSRC=ON&withinResults=&QuerySource=gASr_Query&Product=msall&Queryc=Checksum+Error&Query=Checksum+Error&KeywordType=ALL&maxResults=25&Titles=false&numDays=&InCC=on" target="_new">You can start here!</A>
Have a nice day Goodbye!!!

Thank you for the time you took to answer my questions. I consider them valuable, really. My first impression was that it's probably because of a faulty CD. I had no idea if it could be because of something else, that's why i asked in the first place. Usually, when i ask something it's because i don't know it myself. That is why i had to ask of the relevance of RAM. Because i did not think of that since even until now i had nothing to indicate i might have faulty RAM. So, your suggestion surprised me and i had to ask for the relevance of it before i took actions towards that direction. You see, i hardly ever follow other people's suggestions unless they first make sense to me. If that made you upset, i strongly apologise, but i couldn't have done otherwise. You know, it's really hard for me to learn without asking and even harder to understand something when it doesn't make sense. I think i did say how you could be right but i guess you missed it and thought that my remarks after that were disregarding you when they were nothing more than ways for you to enlighten me and ways for me to be enlightened.
Anyway, i'm really sorry if i offended you with my questions. Maybe, to avoid that in the future, you should only answer to people that share the same knowledge as you do, so that they won't question you in any way where there can be some degree of silent agreement in response to the suggestions you will be offering them.
The reason for this error is most likely a faulty CD: a checksum is a number, which is created from the binary data of a file. In this case the setup prgram creates a checksum of the data copied to the harddrive and compares it w/ a checksum which is saved on the CD and was created from the original data. When they are not identical it aborts w/ this error message. This means, that the data on your harddriove is not identical w/ the origianal data. The reason for this is most likely a faulty CD. Sure the error can also be caused by an error copying the data to the harddrive, which can be caused by an faulty harddrive or RAM, but in when such an error always occurs on the same CD and it never occured when you insdtalled a different program most likely the CD is faulty.
There is a good way to find out, if the CD is faulty: try to install the program on a different PC. If it the error occurs again, to 99,9% the CD is faulty. If it doesnt occur on the other system, your PC is causing the error.
