Ensure the debug is disabled after the logs are collected

This is a generic event logged for all storage device errors. The event was reported in the application log because the Backup Exec job engine received the specified error when issuing the specified command to the specified drive.  This is most often indicative of a hardware failure.  Depending on the type of error, it may indicate that the drive needs to be cleaned or that the media is no longer reliable.  Other errors may be resolved by stopping the Backup Exec services cycling power on the drive or robotic library and restarting the services.  If the problems persist, contact your hardware vendor.

I've gotten this error too.  I have an open case w/ Tech Support, but so far it's been very frustrating working with them.

Good Luck,

My case # is 02862618 and I have been working with Symantec on this for months!

There is still no resolution.

this originally started out on 2 servers and then a 3rd server just started having this issue a few days ago.
