Translation: This error message appears to be telling you that there's a problem with Windows 2000's memory paging system. It could easily convince you to check system RAM or the hard drive where the Virtual Memory page is stored.
In reality, this error message is most likely to occur when you're trying to copy a file from a bad diskette to your hard drive or to another diskette. When you copy small files (less than 256KB), Windows uses a different copying process, one that maps the file into Virtual Memory space. Windows then reads the data from Virtual Memory space, instead of from the slower floppy drive.
If a problem occurs during the file copy, you'll usually see the error message above, which will lead you astray instead of identifying the correct source of the error (the floppy drive or the media).
Solution: Inspect the diskette for damage. Reinsert it and try again. If that doesn't help, a third-party drive utility may be able to recover the file."

What does 'cyclic redundancy check error' mean?
There are plenty of technical resources on the Web that discuss cyclic redundancy checks (CRCs). Most times you won't need to worry about this technobabble. That is, until one it day it suddenly appears and you think - what the heck does that mean? In simple terms, a CRC is bit of mathematics used to ensure that your data is OK when being transfered. It's a checking procedure that quickly identifies when data has been damaged. If you get this message, it means that the file being read by your PC or software is corrupted. However, it does not mean all the data is lost forever. When data is transfered, it is usually in small blocks and each block is given a CRC value. If something goes wrong with the data between the time it leaves the source and arrives at its destination, the CRC sent at the source will no longer match the one that is calculated when the data arrives - this is when the cyclic redundancy check error will appear.
The most common times you will see the cyclic redundancy check error message is when trying to read data from a damaged CD or DVD. Just before it appears, your CD/DVD drive will probably grind and whirl away - your PC may also become a little slugglish.
Less frequent causes are the result of system crashes, and buggy software (hello Microsoft), incomplete downloads (often identified by the misleading message 'This is not a valid Windows file', 'This is not a valid win32 application' or 'Corrupt Zip file'). If this problem happens frequently with downloads, try using a download manager like GetRight. If you have lots of zip files on your system and want to check they are still valid, get a copy of CRC Checker - it's free and can validate zip or rar files in batches - which is much easier than doing it one at a time. This program is worth downloading and keeping on hand for when problems strike.
For CDs and DVDs, the problem is a little different. Normally, when CD/DVD drives get a CRC message from a disc, they try to read the disc again - hence the grinding sound. After several failed attempts, they give up and display the redundancy check error. The problem can be hardware (loose cables, failing drive), software or damaged media. In most cases checking and cleaning the disc is the easiest way to overcome the problem. If different clean discs produce the same error, it is likely to be a hardware issue (check the discs in another drive). Another common cause of these errors is poorly burnt CDs and DVDs - especially those that had numerous or severe buffer underuns. USB burners suffer from this problem when the burn speed is too high (generally above 4X-8X)
If the discs are damaged, you'll probably need a recovery tool to get back your data. CDCheck 3 will work for CDs and DVDs. First it will check the media, and then you have the option to recover the files. It's free for personal use and has saved many people heartache when it comes to recovering lost digital images and videos from damaged CDs.

Invalid MS-DOS function
Several possibilities for this error.
A faulty burn on the CD-R (more common when using a CD-RW)
Copy protection on a file or CD that its been copied from (such as a game)
File content that mimics an error and triggers the message
Invalid characters or too many (>127) characters in a file name and path. <---This is my best guess as to your problem
In all cases there is usually no cure, you may need to resort to the original CD. Is the CD designed to be copied onto the HDD, or run from the CD only? This error is quite common with VCDs and their DAT files, where the VCD will still play but will not copy. There is no error tolerance when copying.
