A bad checksum error is rewarded when the file matrices do not match, which means that the data type element no longer matches the actual original. If your data fails checksum verification, it usually means that you need to replace or recreate a corrupted dump file.

Flash Based Feel Broken.

This Applies Mainly To Router Platforms.

Check The Checksum Of The Size Image And Against The Information Provided In The IOS Upgrade Scheduler.

< Li>A Parity Error Occurred In The Remote Memory While Migrating From Flash . On C2600, C3600 And C3700 Wireless Routers Do Not Support Parity. If, Typically, One Or More Pieces Of Data Are Changed During A Flash Migration, The Router Calculates An Entire Bad Checksum For The Receive Image And Aborts The Boot Process, Among Those Available. Error Reason:

Software Parity Error. If Error Number One Occurs For Only One Week, It Should Be Prepared As Soft (or Temporary) Error Number One. If The Chip Between Memory And MateRin Board Has Poor Contact, Reinstalling The Memory Chips Will Solve The Whole Problem.
Faulty Memory Chip. The Memory Needs To Be Replaced Here.
There Is A Problem With The Memory Or Controller On The New Motherboard. In This Case, The System Board Must Be Replaced.

Resolution

Verify the checksum and the number of Cisco IOS software images by issuing the flash command in ROMmon mode. Compare the values with the Cisco IOS Software image information in the IOS Upgrade Scheduler.
Reinstall the RAM chips. See Installing the Cisco 3600 Series Storage Router.
Replace the RAM chips.

What causes bad checksum?

An “Invalid checksum” error can occur if data collection was interrupted or the data file could not be closed properly. It’s always intermittent problems due to the network. Can the user then check that the data type is complete. The “Bad Checksum” error can also be caused by not properly closing as many of the stored 2D extracted channels as possible.
