I fixed the drive by tweaking the two potentiometers: Sohw-1633 entry was posted in ComputingObituary and tagged computer hardwaredeadliteon sohw-1633s disc.
Use the paperclip to liteon sohw-1633s the tray, unclip the front bezel from the tray, then the body, and you should be left with the following: You will need to liteon sohw-1633s both clips, and lever off the lid to see the innards. Click for more about me!
LITE-ON DVDRW SOHW-1633S resources, firmwares and drivers
Directly in the liteon sohw-1633s of the photo is the lens and the main pickup assembly which contains the lasers and photodiodes which read and write your data. As these drives have, as a condition of me purchasing them, given consent to become organ donors, or to donate their bodies to science, what follows is a peek inside one of the drives just so liteon sohw-1633s knows what lurks inside a slhw-1633s optical drive.
I have no idea, but if somebody does, please liteon sohw-1633s go ahead and write a reply. It was something I had noticed and it drove me nuts, which is why I always had liteon sohw-1633s burners — one Lite-On, and one non-Lite-On. While doing testing for the Milleniata post, I discovered that my two trusty quality test workhorses were dead.
The data from the left one is 0. The LiteOn drives were extremely flexible, firmware wise, in terms of read-speed and write speed hacks, strategy re-labelling and swapping through Omnipatcher liteon sohw-1633s of the big community that had built around guys at CD Freaks which included employees of LiteOn themselves.
LITE-ON SOHWS resources and drivers
I have been able to fix the non-reading issue of my drive. And in the end I have a working drive again. Now you will be greeted with the main guts:. Some of these contain ball bearings which liteon sohw-1633s a wooshing sound when the disc spins up and down common for LiteOn drives which acts as liteon sohw-1633s counterbalance against unbalanced discs sohw-163s3 machines actually have something similar as well!
Remove the base plate. The other potentiometer worked the same, but for reading DVDs.
Thanks for any help! Through this, their drives inherited some of the features the ribbing liteon sohw-1633s the top surface — that was introduced on the BenQ Philips DW first as a way to keep the airflow inside the drive quiet and to harness it for cooling. I was sure that the laser is working because I was seeing the red laser light not directly, liteon sohw-1633s course: One of them is the serial number, the lighter colour one appears to provide calibration data — possibly to do liteon sohw-1633s skew angles of the laser focus.
Lite-on SOHW-1633S Firmware
I will sorely miss these drives, but that being said, laser failure seemed to be a common trait liteon sohw-1633s many LiteOn drives — the fact liteon sohw-1633s have lived such long and productive lives is something to marvel at on its own. One interesting thing is that the laser pickups have QR codes on them — disassembling both drives and scanning their pickups gives us the following photo:.
But the community support always pulled through, and these were also some liteon sohw-1633s my favourite drives when it came to overspeeding media such as the RICOHJPNR01 4x discs which would faithfully burn at 8x, everytime.
Use the liteon sohw-1633s to emergency-eject the tray, unclip liteon sohw-1633s front liteon sohw-1633s from the tray, then liteon sohw-1633s body, and you should be left with the following:. March 3, at 8: The SOHWs suffered liteon sohw-1633s likely combo chip failure and was unable to control its tray, or spindle motor. One interesting thing is that the laser pickups have QR codes on them — disassembling both drives and scanning their pickups gives us the following photo: With that quick diagnosis, I take a moment to salute these fine drives, and send them onto liteon sohw-1633s way towards the garbage.
The whole sled including the disc spindle motor is mounted on a rigid metal frame which is secured to the plastic frame of the drive using anti-vibration silicone grommets — this reduces noise and vibration transfer to the case, but also ensures that the sled and spindle all vibrate in harmony liteon sohw-1633s the disc to maintain good tracking at high speeds.
Now you will be greeted with the main guts: I figured out that if I turn one potentiometer clockwise, the drive stops reading CDs; if I turn it counter-clockwise, it reads CDs again. You will also see the flash chip with the firmware, liteon sohw-1633s with a label that has the initial firmware revision the drive shipped with — BS In this mainboard, the main SOC is mounted on the reverse side — what you see is the connectors on the right edge, the combo motor controller for spindle, tray and pickup sled and the buffer memory from Samsung.
I have to emphasize that the tweaking was done in very small steps.
