    Default Liteon SOHW-832S problem

    ok guys/girls here is my problem:

    i have purchased the Liteon SOHW-832S and i setted it on region 4...for about 6 months and now there is something wrong @.@

    the problem is that although my computer detects the drive however whenever i insert a disc DVD/CD rom there would be no detection of the disc whether its a data disc,audio,dvd movies etc no response and those disc worked on my other dvd burner as well (also using Pioneer DVD-RW DVR-110D (and this time i didn't set the region) )

    also i've checked that there is nothing affecting it eg softwares,memory,other hardwares....

    and here's my comp not so detailed specs had it for a little more than a yr so ya need to upgrade...:

    OS: XP Pro SP2 fully updated....
    MEM: 512 MB (had 1GB but ther other 512MB died T.T)
    HDD: Seagate internal IDE 80GB(too poor >.> invested too much on external HDD's )
    MOTHERBOARD: errr ASUS with on-board stuff like video ,audio,LAN...
    MONITOR: LG flatron
    OTHER: external adsl modem connected using network cable also conected with 6 200GB external HDD (4 connected through USB 2.0 and the other 2 through firewire).



    ps: although i am on unlimited adsl plan however due to myself having alot of space i often download pass the limit in which my speed gets reduced

    ps: ^^ don't bother asking me to send my HDD to u as i only lend them to ppl i know

    Well.. if you think the DVD region is a problem (like if you set it to 6 when you are 4 or something), that can be changed in winXP by going to the control pannel, system, hardware, divice manager, the DVD drive, right click on the drive to get properties, go to the DVD Region tab in properties and set it to what you like. You supposedly only get 5 changes, but I would bet there is a crack for that lying around the internet somewhere (never needed to find it).

    However, that doesn't explain why you can't read data or audio disks, which leads me to believe that the region isn't the issue. Let me ask a few questions...

    1. Does the drive spin up?
    2. Have you tried cleaning the drive?
    3. Has the computer been severly impacted in any way recently (you hit it, kicked it, put it in a truck and went two-tracking, you get the idea)?

    If the drive spins up, then it isn't the motor. Thats good. If it doesn't, then your motor can be blown, or you arn't getting power to it (which means try a different molex connector off the power supply, or a new power supply if you have one).

    Cleaning the drive is an easy task. If you have one of them little disks with the brushes on them, then you can try that. If not, its a easy task to clean it by hand. What you do is open your computer, disconect the drive, pull it out of the computer, get a screwdriver (the tool) and open it up. Now what you want to do is take a soft cotton swab and put a little bit of isopropyl alchohol (rubbing alchohol if I didn't spell that right) on the swab and gently clean the lense of the laser. If you can see something on the lense that won't come off, you can try to apply more force, but every bit is a risk. Scratch or damage that lense, and you might as well toss the drive. As long as your in there, if you have some grease lying around, put a little of that on your finger and grease the runners, gears, and any other tracts that parts move accross. Doesn't take much, so don't overdo it. I have saved a VCR or two simply by giving it a little grease (my Dad has saved around 10 by doing this).

    If the computer has been impacted recently, then you may have a problem with the laser being out of alignment. You will have to recalibrate it. Prepare for one of the most tedious and most pain in the ass experiences of your life. Your going to have to take the drive apart and try to locate one or two little set screws (small nubs usually with an allen head, a hexigon indentation, that goes almost all the way in, or is inset, to the part they ajust). Don't ask me where they are, every dive is different, so I have no idea. Once these are found, get the proper allen driver and start playing with the set screws. You should see that they ajust the pitch, height, and positioning of the laser. Basiclly, you play with that untill you get it to work. Turn, twist, test... over and over and over agian. There should be a way for you to test the drive without putting it all the way back together. Yes, I am talking about doing this while the computer is on and the drive is hooked up. I won't official say I support you trying this idea (in fact, don't try it at all I don't want to get sued), its dangerous to you and your computer. DON'T TRY THIS... anyway, be sure to remember where you started your calibrations from, so you can put it back to what it was if things get worse. Once you start to get close, you can narrow it down to what screws you need to ajust. It just takes time.... lots and lots of time. If time is money to you... may just be cheaper to go get a new drive if its on sale.

    Anyway, thats all I can think of for now. Let me know how things work out.
    Vol~

    i know its not the regional settings i was just stating i did setted it on region 4 out of curiosity however thats not the problem...

    its not the motor fault as it does spin but its the lens however i won't go dissecting the driver as it would cancel my warranty or guarantee and that would be not so good....

    i'll prolly go and try clean it with those cleaning kit however if it still doesn't work then its most likely that something is wrong with the lens and i'll have to bring it back to get that fixed rather myself...

    another thing to check: make sure your jumpers are set correctly, i've seen that cause problems. Another fix may be to remove the ide cable and reinsert it. There could be some corrosion, oxidation messing with the connection. Usually Removing and reinserting removes enough of the bad stuff to make it work again.

    Set your dvd drive to the region you are in. I've been amazed on how careless people can be when they burn dvd's and put region codes in.

    That should work.. definatly try what was suggested in the above post and the only other thing i can suggest is it may be a software issue. Update drivers, reinstall drivers, run antivirus/adware programs and make sure your system is clean. (if you have run any new sony cds in your computer recently go and get the patch to deal with sony's anti-copying software it installs on your computer if you aren't careful).


    Good luck

    Wow if the solutions that Volv and hell gave you don't work then the last resort would be to flash the bugger. The official liteon website is here: http://www.liteonit.com/ODD/English/...e_dvd%20rw.asp

    make sure you flash it with the correct info.. you can easily turn that burner into a paperweight by putting the wrong flash data in (i know from experience.. hehe stupid computer salesman rma'ing my harddrive too).

    can you boot from the drive ? You may have to change the boot order in the BIOS.
