Hi Vikas,
Thank you for your information.
Actully I had a situation to delete B2D folder from my 1TB USB hdd. Using BE 10d i have scheduled the Backup jobs for 5 days in a week.
When i delete the B2D folder in BE as you have mentioned, it deleted perfectly and the job has been moved to another media set and device. But as for as HDD concern, It hasnt allowed me to deleted. When i delete i got the message saying, " the particular folder may corrupeted or unreadable.
After this i am unable to format that disk. if i format, format is completeing but that B2D folders are not getting deleted.
