Reference number: CH000430

Cyclic Redundancy Check or CRC error.

Issue:

Cyclic Redundancy Check or CRC error.

Cause:

This error message could be generated by any of the below reasons.

1. During the transmission of the file it became corrupt or bad
2. The file was sent inappropriately
3. The device being opened from is bad or contains errors
4. The file itself is bad or the program attempting to open the file is bad. 

Solution:

Network / Modem transmission issues

If you are attempting to open the file from a network / modem it is likely the network either is encountering collisions or other errors during the data transmission. Note: if the file is being sent through a session such as FTP or Telnet it is possible that it may not be sent properly. If the file is a text file, the file must be sent as either ASCII or TEXT mode. If, however, the file is a program or non-text file, it must be sent as a Binary file.

• Attempt to re-send the file.
• Try Alternate method of sending the file.
• Verify the file was sent properly (ASCII / TEXT / Binary)
• Verify with Network Administrator that the network is not experiencing issues.

Removable media issues

If the file is attempting to be opened from a removable media such as a Zip disk / Floppy diskette it is possible data corruption is being encountered on the diskette itself or when coming from the removable media.

• Try an alternate diskette or media

CD issues

If the file is being opened from a CD-ROM it is possible the CD is dirty or scratched causing read errors. If the CD was burned it is possible that it was burned improperly.

• Clean the CD-ROM
• Re-burn the software

File is bad or program attempting to open the file is bad

Finally, if the file is being opened from the hard disk drive or other media, it is likely that the file is corrupted or the program opening the file is corrupted.

• Download the file again.
• Reinstall the program being used to open the file
• Attempt to open with a different program
• If the file is on the hard disk drive, run scandisk / defrag
• Assume the file is bad and cannot be recovered
