They will be the old density. The tapes are physically different:

Subject: [Veritas-bu] LTO1 media on LTO2 drives

 


All, 

Scenario: 
We have a legacy of LTO cartridges created/written on LTO1 tape drives.
(referred to herein as LTO1 media) 
The LTO1 tape drives have been replaced with LTO2 drives. 

Question: 
When the LTO1 media is written to by the LTO2 drives - will it be at the new
density or the old density ? 

( I suspect it will be at the old density because the tape is already
"formated" for LTO1 density. ) 

Do I need to erase or label the media to ensure it is written to at LTO2
density  ? 

Thanks in advance, 


Jorge
