error generated during incremental backup perfromed by Norton Ghost

Hello,

 

The Scheduled backup using Norton Ghost 15 did not complete. The following message was generated.

 

"Unable to create incremental recovery point. Error E7C3000F: dEVICE\\?SymantecSnapshoto cannot read 7248 sectors starting at LBA 3447232
Error EBAB03F1:The sempahore timeout period has expired
UMI:V-0-187-131"

 

 

Can anyone tell me what is generating this error.

 

Thanks

Arun
