Most likely that 800 Gb is compressed?

I'm saying that the quoted 800 Gb may only be valid with 2:1 compression, which depends on the data.

Looks like tape is 400Gb uncompressed, and 800Gb in compressed size...

> Are there any settings I should do in Data Protector ?

While formatting the tape, it will ask you to specify medium size, you need to select "Specify (MB)" as 800 x 1024 = 819200 and select "Force operation" option.

After formatting is done, check tape slots properties, in Usage tab, it will show you 800Gb total capicity.
