HELP! Can't copy files from CD-ROM to Hard drive... getting "Cyclic Redundancy Check" & "Invalid MS-DOS Function" errors

[WAZ]

I am trying to simply copy files (via copy-paste and/or drag-n-drop) from a CD-ROM to my hard drive. There are several big files, which seem to be giving me the most problems... but as a whole, files will not copy over. I'm getting an error that says:

Cannot copy [filename] : Invalid MS-DOS function

or

Cannot copy [filename] : Data error (cyclic redundancy check).

I have 2 CD drives (a DVD and a CD-RW), and I get the errors from both. I recently upgraded to Windows XP, and did not have these kinds of trivial problems before.

In seemingly unrelated (but possibly related) news, I also now get miscellaneous "lack of memory" errors with some programs now, which I never got before upgrading to WinXP. I don't know if all of these have anything to do with virtual memory, RAM, or cache/buffer settings somewhere. I'm not a big tech buff, so finding this stuff without breaking something else is beyond me.

So if anyone has any ideas why this would be happening and/or how to fix it, your help would be great.

Thanks in advance--

CRCs is used to verify that data received is the same as the data that was sent.
I would guess that the data being copied to the hard drive is somehow being corrupted in the transfer, what I understand about cycle reduncy check or CRC is that it compares the data that was sent with the data that was recieved and if they do not match the transfer is aborted. I believe in this case that it is a progrm error within your windows OS. The first thing is I would reload your operating system. Was the upgrade to your OS done with a upgrade disk or was this a new install. Also if this was a copy of the origonal os it may be corrupt.
This is the best I can do for now.

Thanks for the reply. The installation was an upgrade from Win98SE, using a brand new WinXP Pro Full Version (got it for $5 through my school). So the disc should not be corrupt. Perhaps it is because I upgraded Win98 instead of installing WinXP fresh?

The weird thing is, this is the only problem I've had since upgrading... everything else is perfectly fine.

Anyway, I may try to re-install WinXP fresh and see if that works. I've been putting off formatting, but I'll do it if that will fix this problem.

Thanks again for the advice--

Make sure you have the latest BIOS and chipset drivers for your motherboard and make sure you have the latest IDE drivers if you're using a third party IDE controller.

Also check your DMA settings on your drives and check your cables if they're plugged into the right place and firmly attached. Also make sure that your power supply is big enough.

Finally, close all background programs and don't multitask while the file copying is taking place.

Where do I adjust my CD drives' DMA settings, and what should they be set to?

Thanks!

How did you upgrade from Win98 to XP Pro? If I pop an XP Pro disk onto a Win98 machine, it tells me that an upgrade is impossible. I thought you had to have Win2k to upgrade using XP Pro?

you can upgrade from win98 to either XP Home or XP Pro!

look in device manager under properties of your ide controllers!

My DMA settings are correct (I believe), and I have no other problems with my CD drives. But I still get the data errors, invalid MS-DOS functions, and cyclic redundancy check messages when copying large files (approx 10 MB or larger, sometimes more, sometimes less) from my CD to my hard drive. I can copy small files just fine, but larger ones are still getting these weird errors.

So here's another bump as I ask for more help...

Thanks!
