crc error
 

Hi

Last night I installed a cdrom in my linux PC.
When I booted linux I got the following error:

crc error

system halted

My configuration was as followed
hda (linux) primary master
hdb (cdrom) primary slave
hdd (vat) secondary master (my mp3's)

After I fiddled with the jumpers and IDE cables it booted normally again.

Now I know in the IT industry there is a unwriten rule that states "If it ain't broke don't fix it!", but I am very curious person, (witch is part of why I use Linux).
So I would really like to know what this "crc error is.

Any Ideas???

PS. I am running RH7.1

crc= "cyclical redundancy check"

Simple, basic answer: it's an error-checking scheme used to verify the integrity of data when that data is copied from one place to another. In other words, a comparison of the target file is done against the source file to see if they match. If they don't, there's a chance that corruption occurred during the file copy/transfer. If your connections/cabling/jumper configurations were dodgy, there's a good chance that information did not get from "point A" to "point B" intact, hence the CRC errors.
