That drive is now around 9 years old, and the plastics its made of will have warped enough to put it out of commission by now even if it was sitting on the shelf in a sealed box till now. I have experience with 3 of them, one sat in an NT box and backed it up for almost 4 years on the same tape, but when it died, it ate the next 3 $50 tapes we put in it by ripping them in two. Also the cleaning tape after I had hand cleaned it. Of the other 2, one never was able to complete a backup run. HP recycled it a couple of times without fixing it, we tried 3 controller cards etc, couldn't make it work more than 2 or 3 nights in a row, ripping up a $50 tape everytime it failed. The last one ran about 4 months, ripped up a tape, came out and never went back into anything but the out bin. We saw the handwriting on the wall very clearly, built a half a terrabyte raid and fired up rsync. The raid has been expanded to about 1.5 terrabytes now, but the script hasn't changed other than adding new machines from time to time, and we've had to do several near bare metal recoveries from it, 3-5x faster than tape would be. Its almost a routine when box so-and-so fries a cpu or drive. Fix whatever fried, fire up the inverse rsync script to restore that machine and haul it back to the desk it belongs on, all in the same day. HP T4000s's, like any DDS2's are to be avoided, they are simply too long in the tooth to be 100% functional in the YOOL 2005. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
