Sorry to butt in but we are having massive compatibility problems after
going from seagate drives to ibm drives (ordered IBM drives, seagates turned
up then we got replacement IBM's a month later)

I knew there was a problem but untill now never heard of anyone else with
it, can you tell me where you got the compatibility information about the
problems between the makes and what HP's fix is please.

I may be able to seep nights again :)

Hi Chris!
I´m working with LTO, AIT, S-DLT, SLR and et c.
But what are you going to backing up. That is the question.
But here is some good point on AIT and LTO.

AIT3 :
Fast access (Access to first data  under 10 Sec)
12 MB/s (Uncompress)
Read/Write header have a plastik shild so it´s easy to clean.
Less Shosining. (Tapes lifts longer)
The tapes take less space.
Read/Write back well compatiboly.
But new tapes each time when you upgrade to a new ver.

But I don´t like the ADIC library. I think if you want AIT talk to Spectra
Logic insted. Much better library.

LTO :
Open Source technoligy. So that mean more then one company developing the
technoligy.
16MB/s uncompressed.
Next generation is on it way. So you have 200 GB on each tape uncompressed.
Don´t know if you can write on the old tapes. But I haird that LTO2 is new
tapes. So that mean you still need to buy new tapes when you upgrade from
LTO
to LTO2.
And LTO have some problem between Seagate, IBM and HP ver of LTO.
Ex. (Don´t no if there have fixit on Seagate and IBM but HP have).
You can not run a cleaning tape who is from HP on a IBM drive?
And I hiard some people have problem to read tapes who have wroted buy a
nother
drive who is create buy another company.

But the question is. What are you going to backing up. And how fast do you
want
to restore it?
Do you want short restore time on small files?
Then you going to choice AIT.
If you going to restore big files?
Then choice LTO.

Med Vänliga Hälsningar/Best Regards
Christian Svensson
