Below mentioned error is expected to be seen during verification as it is highlighted specific chunks that are not found or corrupt. To investigate further please refer log Dataverf.log

Error Code: e13:138] Description: Error occurred while processing chunk n7670174] in media iV_], at the time of error in library rLibStorage] and mount path thLibStorage] R:\], for storage policy cSP_BackupSystem] copy pAux_Disk] MediaAgent n]: Backup job o]. Mount path inaccessible. Source: , Process: AuxCopyMgr  

Thanks, it is true.

In my case are specific chunks that are Inaccessible. 

Is there any way to try to access them?

Hi,

Can you check on OS level if these folders/files are still available?

If not, we need to mark those jobs that are reference these blocks as bad. For that I would advise to open a case with support.  

Every time I send an auxiliary copy to tape, it tells me that the Chucks are not available for the operating system.  The end user put the MA installation path inside the drive where the backups are located, can this be the cause?

@PedroRV , I see you already (wisely) created a separate thread for this (where I already replied).

Thanks!
