Have you installed Symantec Tape drivers for this Tape? This model doesn't appear to be listed in the HCL as supported device (the backups should still work as LTO6 drives are supported).

If a short erase doesn't solve it.  I'd chalk it up to formatting overhead.  

There is an online portal, save yourself the long hold times. Create ticket online, then call in with ticket # in hand :-) http://mysupport.symantec.com "We backup data to restore, we don't backup data just to back it up."

There is sometimes issues with communication involving OEM drivers.  It is recommended that the Microsoft default drivers are used with a medium changer.  To reset this go to 

  1.  right-click the OEM driver > Properties > Update driver.
  2. Updating the driver will install the Microsoft driver; Unknown Medium Changer will be displayed

What interface (SAS/FC)?  What height drive (full/half)?  Unless you have some weird combination, that library & drive are on the BE 2010 HCL.

IBM LTO6 capacity shows up in my BE as 2.27 TB.  That is based upon what the drive is telling BE, so there may be some rounding involved, or conversion between advertised & engineering units of measurement, or other reasons the drive reports what it does.

It sounds like you are supported and reporting correctly.

If you find this is a solution for the thread, please mark it as such.

I think what is happening is Windows reports it as TiB, and you're reading it from the manufacturer as TB.

2.5TB is about 2.27TiB (right around the 2.3 you see)

So it's all a matter of base 10 or base 2, TB or TiB, etc...
