Can I get you to run me a drive dump from the TL2000 so I can look at the drive to make sure that there are no issues with the drive. You can run the drive dump from the web utility by going to Service Library MenuSave drive dump. It will ask you for a place to save the file & then it can take up to 15 minutes to pull the file. I will send you a private message so that you can email me that file to review.
Also you stated that you have a dell server I wanted to know which model you had as well as the controller card Drivers that the TL connects to is using.
Let us know if have any other questions.
