    DLT drive write errors.

    I bought this internal VS160 DLT drive (rebadged as a Tandberg Data VS160) almost a month ago and when I first got it, I installed it, loaded the drivers and ran a backup and it went off without a single hitch. I then set the server to run a complete system backup cycle in the first of every month and left it alone.
    So the first comes around and when I get back from work I check it and...I got a read error about four minutes into the backup.
    I tried again. Went a little further and then gave a read error.
    I then tried another tape. It again gave a read error at another random time.
    I assumed that while the CLEAN light was not on that it might still be dirty so I loaded the cleaning cartridge in and ran a cycle and then tried another new tape (so now I'm on my third VS160 tape) and again, I get a read error at a random time.
    It's not having issues with any particular files and between the first time I used it and now it had been in the server (which run 24/7) with a tape loaded in it, doing absolutely nothing. I see no reason at all why I should be having this unless the tape I had loaded got stuck to the head and there's residue on it that teh cleaning tape did not remove or something. It makes no sense at all and so long as I have no way to back my system up, all my files I added/edited since the last backup are at risk of being lost (and these drives are already almost 5+ years old and have been running non stop for probably their whole life).

      Blow out the innards with compressed air and clean the tape head with a foam q tip dipped in alcohol.

      Maybe somethings gummed on there?

      Want to rule out hardware before software.

      Does the cleaning tape accept alcohol through a hole or is it a dry cleaning tape?

        After 5 years I'm surprised there's still any life at all left in the read/write heads.

              I had a funny issue when i upgraded the tape drive in our old domain controller from a HP DAT drive to a HP LTO-1 drive.. I accidently connected the new SCSI cable that came with it, that had LVD termination, to the place where the old tape drive was connected which was an SE connector.. Funnily enough, it would detect the tape drive, and even read data correctly, but writing it hated.. After i moved the cable to the LVD connector, it worked perfectly..

              What kind of SCSI card are you using, and with which OS???

                  So the answer is an alcohol soaked q-tip possibly?
                  I'll haee to go buy more q-tips an rubbing alcohol but I'll give that a try.
                  How could the heads be worn out?
                  I have seen QIC-150 drives still in use that still run fine and they are WAY beyond their prime.

                    Hmm. That's odd.
                    I was forced to reboot the server last night and after that was done I tried again for the heck of it and it completed the backup with no problems.
                    I guess something on the bus had to be reset.

                      Problem

                      This is an LG edge LED lit LCD Display. The LEDs are on the bottom edge of the display. There are 2 bars (left and right) Each bar has many LEDs and a 6 pin connector. Each pin drive several LEDs thus is the highest current flow / heat junction. The weak lead free solder gradually fails with thermal expansion/contraction cycling and increases resistance. PSU will compensate up to a point, then when the current is too high, PSU just shut down the backlight causing a dark display. I have even seen one which the connector just fell off as solder points became completely detached....

                      LG 75UN8570AUD panel issue fixed with tape.
                      by triplefour
                      I've been seeing a lot of the new TVs (samsung and LG only i think) maybe 1-2 years old suffering from sudden panel death and have been over 50% successful bringing them at least most of the way back to functionality if not all the way, with the tape masking of the LVDS pins method.
                      add this one to the list. the issue was on the left side of the panel and i ended up blocking just 3 pins on the connector that joins the two panel boards that make up the left side of the panel (it has 4 boards total) i didnt get the picture back to 100% perfect. i spent hours fiddling with which pins to block...

                      bug of the month: write caching setting for the hard drive in device manager
                      by ChaosLegionnaire
                      i recently bought a new wd re4 2tb with 2014 datecodes. when i got around to testing it tho in victoria hd tester, the write speed was very slow at 14 mb/s with a 256 sector transfer size. when i increased the transfer size to 1024 sectors, the write speed increased slightly to 44 mb/s. read speeds and sector verify speeds were fine and at normal speeds.

                      so i just ass-u-med the drive's poor performance was due to it being an advanced format drive and i was using it on winxp. when i tried cloning my system disk to this wd re4 2tb drive and writing to it in linux, the write speed...

                      IBM LTO 7 Tape Drive - Dust Sensors??
                      by RetroComputingGrotto
                      I have a Quantum SuperLoader robotic tape library that uses an IBM LTO 7 tape drive which is constantly complaining that it needs cleaning. If you insert a cleaning tape, it performs the clean and resets the cleaning counter to 0 hours. It should only require cleaning every 50 or so working hours but after as little as just 1 hours use it requests cleaning. We've purchased a new cleaning tape along with new LTO backup tapes but that has not resolved the problem.

                      I have taken the library apart and can see no noticeable signs of dust inside. I have removed the tape drive from the...
