Need advice on LG UH12NS40

[MrCrunchy]

I have a LG UH12NS40 with the original firmware of 1.0 and It has worked okay allowing me to rip 40/66 UHD disks. Of the 26 disks that wouldn't rip I got either 'Read Errors' or 'Hash Check Errors' which led me here to figure out it's probably the drive having issues. The dilemma that I am now running into is that I either need to flash another firmware to this drive to make it maybe work on the other 26 disks or to buy another drive to finish off the rest and the future disks I acquire. I remember reading somewhere on here about putting an Asus (I think) firmware on the LG drive and it works better on some disks but I don't remember as this was a while ago. I'm trying to do this on a budget and I am still very new to all of this, any advice or recommendations are welcome. Thank you

Did you give those 26 discs a good cleaning before attempting to rip them again? If not, that is your first port of call.

A firmware change most likely won't make a difference. If cleaning the discs doesn't work, get another drive, preferably a Pioneer from one of the sellers here.

I have with my breath and a microfibre cloth, but frankly, with so much contradictory information about how to clean the disks properly, I'm not sure which is the best way. I've heard both use and don't use alcohol, just use your shirt, and use water and a microfibre cloth. So I tried just to use my breath and a cloth.

I'd love some good pointers on how to properly clean a disk without it destroying it.
Thank you!

Personally, I like to use plenty of water and a bit of dish soap to clean a disc.

The data on a disc is written in a big spiral from the inner ring to the outer ring. (The second layer is written from the outer ring to the inner ring.) I get the disc wet, add a bit of soap, and lightly use the pad of my finger wash the disc. I move my finger from the inner ring to the outer ring and back in a straight line, slow rotating the disc in my hand. I'm trying to move my finger perpendicular to the way data is written on the disc. I do this so that in the unlikely scenario where I accidentally scratch the disc, I minimize the length of the continuous block of data destroyed. Water and soap are lubricants, so be sure to have plenty. The soap is useful to remove films, oils, etc from the disc's surface. After scrubbing the whole disc, rinse with plenty of water to remove all the soap. I then lay the disc label side down on a towel and use a can of air blow the water off the data side of the disc. (you could use a good microfiber here [again, moving perpendicular to the data], but I prefer to minimize how much I touch the data side of the disc) Be sure the disc is dry before trying to rip as you don't want water to be spun off the disc inside your optical drive.

To clean safely without damaging them, follow these steps: Use a soft, lint-free cloth or a special disc cleaning kit. Lightly dampen the cloth with water or a suitable detergent and gently wipe the disc from the center outwards in a straight line. Avoid circular motions as this may cause scratches. Then dry the disc with a clean, dry cloth to avoid water spots. Hold the disc by the edges and avoid touching the surface. Avoid using harsh detergents or sharp objects.
