It's not consistant, get a sample and test the hell out of it. With Linux
you can just dd a file to it and then read it out and compare the results.
Or script it or actually write C code to do it. A ten pass comparison each
writing a different of bits and reading it looking for errors is minimal
acceptable.
Having access to a system that quantifies the esoteric capabilities of the
tape would of course be nice and the cost of a monstrous huge SUN terabyte+
storage array.
Then if the tape 'good' buy the tapes with the same date code. Hit hand with
hammer to remind your self you're buying tape and to remind yourself of
future pain. Better is a random 10 unit selection from the same lot. If
you're buying one, test the hell out of it prior to running out of time to
return it.
And as a final note, I've had such bad luck with tape technology I use IDE
drives as removable media. Look at the costs and see, a 120G drive vs the
storage capacity in tapes. For 'removable' there are a number of options
for quick connect and disconnect. I truly love 2.5" drives in USB boxen,
it's more expensive than 3.5 but fits in a pocket, this is for personal
use. For bidness go with 3.5".
Cost effectiveness, the cost of the tape drive + (cost of tapes * storage
capacity) vs Cost of IDE drives + cost of hot swappable removal system)
All prices were quickly glanced at, do your own numbers and math. I looked
at the uncompressed capacity of the tape not the filthy compression crap.
If you're not using tar+gz for storage and compression, pain is your friend
and a recovery house is gawd.
Belkin USB enclosure: 79.00 for 3.5" drives. Cheaper is available
http://osdn.pricegrabber.com/search_getprod.php/masterid=608970/search=usb%2520enclosure/ut=1891dab12a66cbd1
120G drive 159.00
Tape drive 400
Tapes = 120G: 69
So four USB cases and four IDE drives is 952.00
It's portable to most any computer. You can even make one bootable to an OS
and run that OS for backup/restore if you've had a complete crash and burn.
If you need CD/CDR access, slap one in a USB case they work fine with USB
2.0.
Tape drive system + 7 tapes, 676.99
Screwtapes.
