We have about 3,000 K tapes in service currently within two atl's (one with
16 drives the other with 8)
One environment takes in between 700 & 1,300 GB a day (ok, average about 1
TB) of compressed client data
the other isn't as heavily used (yet) and takes in about 200 GB daily
In the past 6 months I think we had one tape's leader block flip off the
~little rod~ right as the tape was finishing a rewind so it didn't unload
the tape properly.
We've had the typical handful of I/O errors that resulted in a tape being
marked "readonly" but the tape was really OK...
Having good luck here...
I believe our tapes are the Imation black watch extended 3590's
(we use Media Recovery out of Kansas City, Missouri... Tom McHugh

Subject: How reliable are your 3590 K media
We have recently installed two 3494 libraries utilising 3590 K media.
I am experiencing media failures (I/O errors) for about 1 in 10 media
when initializing with label libv. Some of the media does successfully
initialize on the second or third attempt but this does not fill me with
confidence.
I have even had a situation were a tape was torn then wrapped itself
around the internals of the drive when the mechanism snagged on a very
poor splice on the tape.
My question ....... is anyone else noticing problems with K media. Yes
or No, either way I am interested to know so I can see if there is a
correlation between the media vendor (IE IBM, Immation BASF etc).
Thanks
