cannot write to transaction log "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_Audit.log

Hi friends,

My server Intelligence Agent (SIA) can not start because the database service "SQLAnywhereForBI" can't start also. I got the following error :

"I . 08/09 20:35:06. A read failed with error code: (1392), Le fichier ou le répertoire est endommagé et illisible.

E. 08/09 20:35:06. Fatal error:  cannot write to transaction log "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_Audit.log"

E. 08/09 20:35:06. unable to start database "C:\Program Files (x86)\SAP BusinessObjects\sqlanywhere\database\BI4_CMS.db"

E. 08/09 20:35:06. Error writing to transaction log file

I. 08/09 20:35:06. Database server shutdown due to startup error "

inside the database log file.

Please, can you help me
