Take the CD and wash the data side (side without the label) with mild detergent and then clean it with a soft cloth that won't scratch the surface. This should work for most CD and DVDs. Also sometimes different CDROMs or DVD reader on other computer will be able to read the bad CD or DVD.\n\nYour getting CRC (cyclic redundancy error) because the CD or DVD is scratched so the data can not be read properly. A CRC check is done on data read from a media source to make sure it is read properly so when the check fails the computer knows the data it read is unreliable. Thus it shows the error. For more technical explanation look up CRC error on google or something.

What system are you running?\n\nWhat disc did you copy them onto?\nIf you have put them onto a standard CD they are always going to be read only.\n\nIf you are using XP and the files are on your hard drive then you can change the file attributes buy unchecking the 'read only' box in file properties.\n\nSome more details would help us help you more.\n///

try using a different “working” CD/DVD to make sure that the problem is not with your CD/DVD

Hello,\n   It may be possible that your firewall or securirty settings are preventing you from acessing this file, in such a case i suggest disabling your safety settings, (DO NOT DELETE) make sure yout turn strait back on after you have tried this!\n    On the other hand perhaps your disc drive can not recognise the disc, check it for scracthes or disfigurements. If this is the case take it back and try again\n\nI hope this is useful

under linux or cygwin use the split command.\n\nRoxio CD software will handle it for you. \n   search help under split or size to find more about it.

Will it recognises old cd's? Actually for these type of question you should tell what exactlly is happening and is the error you are getting?\n\nCheck whether it recognises other cd's. If yes then check the new cd is working or not. You can check that in your friends pc. If it is getting regonised in other systems then your cdrom might have gone means it'll have a thing called head. If that goes some time it'll recognise some cd's some time it wont.\n\nClean the head using head cleaner

if the cd-rom is copy-protected then you won't be able to copy it, otherwise launch Nero Express and select the option "Copy Entire Disc"\nthereafter, choose the source & destination drives accordingly and proceed by clicking on the "Copy" option.

Never heard of that format. But, if the files are on a CD and you can no longer read it, then they're gone. CD's are very unforgiving.\n\nIf they're that important, then you should have had more than one backup.

Copying copywrited DVD's is illegal.  :-)\n\nTry and find yourself of DVD XCopy Gold

There's something wrong with your hard disk. If you can capture all the writing that comes up after the error, that would help, but in general, this is something you will not be able to diagnose and fix over the Internet. You will probably get a recommendation from someone to format the C drive and reinstall Windows-- don't do that yet because you'll lose all your data, and it might be too drastic a step. But it definitely sounds like the disk itself is the issue and you'll need to take the computer to be repaired.\n\nBasically chkdsk is a system tool that checks the integrity of the disk. If it keeps croaking on 79 then that's where your problem is. It could be logical--- the operating system has lost track of how to count and identify the files--- or it could be physical--- a bad sector (storage area) on the disk. \n\nIf you can make the error come up again and copy down the first 2 lines then post them here (or PM them to me) we can see if we can get some better insight.  The important lines are the ones beginning with "STOP"  and probably says something like IRQL_LESS_OR_EQUAL or like that.

If you're copying to your hard drive, then it might be going bad.  You should probably run a chkdsk on it.

The problem is typically caused by a gap between the CD being ready for data and the computer being ready to provide it. Oddly enough, it tends to be more prevelent just before a CD drive fails.\n\nHowever...\n\nEnsure your screen saver is OFF. Disable the PC from broadband and then disable your antivirus. (I take it you have checked your laptop for virus' and spyware infections using something like SpyBot and Trend Internet Security Online Scan????)\n\nEnsure the only program running is your CD Writing software. Reduce the write speed to 8x. If it writes okay, increase the speed to 16x. If it writes okay, try 24x. If it still writes okay, enable the maximum speed (and curse me for wasting all these cd's)
