Re: [Networker] Premature marking tapes full

Well, this is now getting a little bit confusing. I have IBM LTO-2 tape drives 
also and ADIC Tech. Support advised me that the firmware 4AP0 is the latest and 
now we have 2 different firmwares on this thread, which one is should we use?

I have not seen the LTO2 tapes that sensitive to firmware.  That said,
StorageTek anyway is shipping IBM LTO2 the latest firmware of 53Y2. Before
that they were shipping 4C60. 

I would ask ADIC what driver and firmware they reccommend.
