Cyclic Redundancy Check Error


Recommended Posts

I have a question for you all. I have a pretty important file on a CD that I need to copy to any other type of media so I can get it to a hard drive. No CD or DVD drive will copy the file completely, on a Mac or PC. I keep getting a cyclic redundancy check error. Is there any way to recover this file? Thanks.

You are getting the error because the CD is damaged. Have you tried wiping the CD with a soft cotton cloth? Make sure to clean it from the center outwards. If this doesn't work, then there are several (debatable) CD cleaners that will clean the CD. I have had limited success with these, but it may be your only hope of recovering the files.

If the CD is damaged, you can try a program called CDRoller. I have had many successful attempts at recovering files from a cd that windows itself could not read or access. Depending on how damaged the CD is and the size of the file, it can take up to 24 hours ( from experience ) to recover the file.

This is easy. Just use a program like CloneCD and make an image (ISO for example) of the CD. Be sure to check "skip errors" in the options. Once you have the image file on your HDD use a program like MagicISO or PowerISO to open the image file and extract the file(s) you want.

Did the trick for me several times for AVI files. Good luck !

    • Microsoft accidentally replaced Windows 11 startup sound with one from Vista by Taras Buria The recently released Windows 11 Dev and Beta builds introduced some welcome changes and improvements. However, those preview builds are not flawless and have a pretty long list of known issues. One of those issues, though, is a rather delightful one: Windows 11's default startup jingle has been accidentally replaced with one from 2006. After Windows Insiders discovered that Windows 11 now plays the Windows Vista startup sound and reported it to Microsoft, the company acknowledged it and added it to the list of known bugs in the latest Windows 11 Dev and Beta builds: This week’s flight comes with a delightful blast from the past and will play the Windows Vista boot sound instead of the Windows 11 boot sound. We’re working on a fix. Although Windows Vista is nearly two decades old, it was brought to everyone's attention this week after Apple introduced macOS 26 Tahoe with its controversial "Liquid Glass" redesign, which many consider a rather miserable remix of Windows Aero from Windows Vista and Windows 7. While it is definitely an interesting coincidence, Microsoft did not intentionally replace the startup sound in Windows 11 preview builds. Brandon LeBlanc from the Windows Insider team confirmed in his X that that is a bug after joking about everyone talking about Windows Vista once again in light of Apple's latest announcements: It is worth noting that if you miss the startup sound of Windows Vista, you can still use it in modern Windows versions. All it takes is the original WAV file and a few clicks in the Windows Registry and Sound settings. And for those who want a shot of nostalgia, here is the sound of Windows Vista startup: What startup jingle do you like more: Windows Vista or Windows 11? Share your thoughts in the comments.
    • I refused at $70, $60 was cutting it close for me and I only bought one game at that price, CP2077.
    • Markets are always a follow the leader type of place so to speak. MS didn't raise prices first, but after everyone else did, they will to. Besides, at least they're doing other pro-consumer moves like Play Anywhere. In this case, you can think of it as $80 for 2 copies (console and PC) while Sony and Nintendo would just charge you for both, so $160. Regardless who does it, $80 is too much, even $70 is IMO. Lots of games still come out at $50 and sell well, even if your budget is higher, at $50 the odds are you'll sell more copies and just make it up on volume.
    • How about letting us do an in place upgrade from recovery that would be amazing.
    • From an actual owner (ME) this does not work even remotely good at low speeds.
