Hi,

I am new to this issue. "Cyclic Redundancy Check or CRC error."

I am trying to install a program my friend shared to me. Every time I install it, it shows me that error. I am using a DVD for the program. I have checked all settings in my PC, everything is the same, did not change anything.

Is my OS incompatible with the program being installed?

Hello,

First of all, don’t worry about your OS, its fine. That error is telling you there is a problem with the media being inserted or where the data is being extracted. You mentioned you are using a DVD, here some questions I want to ask you; is your DVD new? Does it have scratches or dirt on the silver/black plate?

Solutions can be:

  • Clean the disk with a cleaning pad, removing dirt and smudges. properly hold and insert the disk. If problem still persists, the media itself is damaged. Try to recopy it with a new media if possible, or buy a new program.
  • If you are using other devices like portable drive, USB; the device might be damaged. You can try to remove and insert it. Try cleaning the USB ports with a cleaning pad or brush then insert it. if same problem shows up, the device might be damaged.

Hope this helps.

Hi,

The CRC which means “Cyclic Redundancy Check, is a tool or mechanism which confirms that the data on a media like Floppy diskette, CD,DVD or Hard Disk, is the same that was written or copied on it.

The reported error means:

  • At the time of writing the data, a calculation was made on per block of data, which is called checksum and is written with the data, and at the time reading this data, same calculation is performed, and if a different number is read, the CRC error occurs.

The reasons for bad CRC are:

  • The device that wrote the data has problems, like dust, malfunction. 
  • The media the data is written has flaws, like scratches, dirt, or are off center.
  • The reader where this written data is being read developed flaws, like, dirt, bad alignment.
  • To check, simply try to read the same disk on some other computer / drive, if it can be read on other drive, than the issue is with the original reader where the CRC error was reported, if it can’t be read on other drive, than the issue is with the media.
