Hi Swati,
Devspace 'F:\sapdb\CDB\saplog\DISKL001' marked as bad at position 80
As per above message it looks like log file for CDB database has some corruption. CDB is mostly used for caching in SAP DMS. Incase you have not enabled caching, you may restore CDB from old backup or re-install only the cache server again in your system.
