how many times a year should i use sata dvd burner drive to keep the mechanics good?
-
Perhaps, twice a year.

Is it necessary to put a disk in the drive during this procedure?

Is it necessary to put a disk in the drive during this procedure?
Yes. To properly 'exercise' the electronics and mechanical parts. Read/use some kind of DVD, for perhaps 30 seconds to a minute or so. That then should move the mechanical bits around, give some electronic bits a test/use, and not excessively wear out the parts. From this regular, 'service' of sorts.
Without a DVD/CD present, the motor(s) and mechanical bits, may not even move at all. I'm not sure, off-hand, if a DVD player, would do anything, if there is no disk in it. It might. But even so, without any disk in it, you wouldn't know if it has developed any problems/issues so far (except for any self-checks DVD drives may perform, even without any disks in them). Without accessing a real disk.
Also, the act of opening/closing the DVD drive tray or slot, to put the DVD/CD in/out. Is also, more fully exercising, ALL parts of the DVD mechanism. Because any part that is left for huge lengths of time, e.g. 20 years. Without being used as such. **could** possibly seize/fail and/or have an undiscovered issue with it.
I'm NOT an expert on DVD drives as such. But would suspect that, keeping a few different types (makes and/or models), perhaps 2 or 3. Would help mitigate, the fact that they can suddenly/unexpectedly fail, over a period of years or decades, in storage.

1) I have two new asus s csds drives 6 months old I turned them on for 1 hour and opened and closed the tray but I didn't put optical disk
2) another question: one of my drives does not fully open the tray it opens 80% how to solve without opening the drive?
-
2) another question: one of my drives does not fully open the tray it opens 80% how to solve without opening the drive?
I suspect, DVD drives detect that the tray has finally reached 100% of its travel. By detecting that the motor current, has dramatically increased (then it also protects itself, in the case where the protruding tray, hits an external object, too close to the computer). Probably with a timeout (to shutdown, anyway) as well.
Which could then mean the tray is NOT freely able to move backwards and forwards, hence prematurely triggering the DVD drive to stop at 80%, rather than the full 100%. Maybe there is some obstruction (internal to the DVD), sticking mechanism towards full travel, or perhaps the original lubrication (if necessary) is missing or removed.
Some/many of those things, can be done WITHOUT opening it up.
Possibly, if it is a truly brand new drive, and still almost never used. Maybe it just needs to be used a dozen times or so, to loosen up the tray and mechanism, from slight manufacturing imperfections.
Sometimes drives sold as "Brand new", are really old stock and/or refurbished and/or customer returns. Especially if it wasn't bought from a reliable/trustworthy company/seller.

my drive is samsung asus new what do i do to open tray 100 percent?

If it's new from a decent supplier. Then return it as faulty for a refund or new, replacement drive. Under guarantee. If the 80% is too limiting, to easily put DVDs/CDs in or out of it.
When you say 80%. If that is enough to easily put a DVD/CD in or out of it. Then maybe it IS fully coming/extending out, as was not designed/intended, to go any further. Fully extending, would hit the end stops. Maybe they intentionally designed it NOT to do that, to preserve its life/reliability. As hitting end-stops, may tend to wear out the drive faster (I would suspect).

the two models of my drive are the same one opens the tray 100% the other opens 80%? if I pull it from 80% to 100% by hand, will it damage the tray?

Many types of CD/DVD tray mechanism use a plain rubber belt drive between the loading motor and the first gear of the loading mechanism. A common sign of a failing drive belt that is slipping, typically on the motor pully, is failure to fully open or close the tray and load the disc. Once it starts slipping it will typically deteriorate to complete functional failure fairly rapidly.
Plain (unreinforced) rubber belts have a finite but unpredictable life, typically either hardening and cracking or turning into soft goo with age. They deteriorate faster when under tension, in contact with certain plastics, or due to chemical contamination e.g. from outgassing of lubricants in other parts of the mechanism, or exposure to ozone or other strong oxidizers, UV or sunlight, or elevated temperatures. Once they start deteriorating there is nothing that can be done to restore them, and replacement with a compatible new belt after carefully cleaning any residue off the pullies (which if left can cause rapid deterioration) is the only effective solution.

1)I don't have much time to constantly open the drive and do the procedures but I want to preserve as much as possible using the drive sometimes is it good or bad for mechanics and electronics? 2 times a year
2)preserve as much as possible in the future when the belts fail can i get the best quality belts possible? what is the best quality?
3) the two models of my drive are the same one opens the tray 100% the other opens 80%? if I pull it from 80% to 100% by hand, will it damage the tray?

I hope the exercise interval is at least > ~8 years because that's the last time I used mine. :-DD

Change that into:
Once it has deteriorated so far it starts slipping, complete failure is also near.
-
Fair enough, as most can slip with a good belt if the mechanism is overloaded, but typically recover if the cause of the jam is removed.
Maybe change to "Once it starts slipping due to belt deterioration it ...", as I said "functional failure" because engaging the disc hub clamp at the end of the loading mechanism travel typically requires more force than tray movement, so though it appears externally that the disc is loaded, it either fails to spin or isn't gripped well enough for the tracking to lock when the disc spins up, resulting in an error status and spindown. The failed belt may well still look OK to a casual visual inspection.

OTOH, replacing the belt is a pretty trivial operation. Fortunately the belt is used only to load/unload the disk and move the tray so the drive will most likely work just fine afterwards.

the worst happened at this moment the tray did not open using the drive hole and button but the drive works and is new ASUS 24F1MT/BLK/B/AS no one in my city works fixing dvd drive

Well, here in the UK, they are currently £13.49, with a few different ones, available to buy. E.g. https://www.scan.co.uk/products/liteon-ihas124-14-dual-layer-dvd-writer-24x-dvdr-8x-dvddl-dvdplusrw-x8-rw-x6-sata-smart-burn-smart-x (https://www.scan.co.uk/products/liteon-ihas124-14-dual-layer-dvd-writer-24x-dvdr-8x-dvddl-dvdplusrw-x8-rw-x6-sata-smart-burn-smart-x)
Assuming that you are being truthful about living in Belgium (as opposed to Brazil), which I would imagine has similar DVD drives for sale, at reasonable prices.
At £13.49 brand new. It is simply not worth spending (presumably) a number of hours fixing the DVD drive, costs of premises, other over-heads, equipment etc, plus the cost of replacement parts. In a persons salary alone, that would be perhaps 30 minutes of their time.
Also, things tend NOT to be designed and built, with easy repairability in mind.

can i fix this? it is complicated? How to choose a good belt? open the drive without breaking the plastic cover
my drives is new, other drive is fine open tray

It is very easy, just don't do it on a still good drive if you haven't done it before. You don't want to damage something accidentally.
Find an old CDROM or DVD drive and try it first on that - most drives are mechanically pretty much identical. You remove the screws holding the metal "box" of the drive and then the belt driving the tray will be pretty self evident. On many drives you don't even need to disassemble it. See e.g. here how to change the belt:
https://www.youtube.com/watch?v=21AnFs3DaKI (https://www.youtube.com/watch?v=21AnFs3DaKI)
If the belt is so bad that it fell apart or got stuck around the pulleys, you will need to disassemble the drive and clean the remains out. You can get spare belts even from Amazon but in a pinch a short rubber band or o-ring will do as well. It is not driving anything critical inside but may not last as long as an original replacement.
In the worst case you can use the drive without any belt at all. But you will need to eject the disc by pushing a paperclip into the tiny hole on the front of the drive in order to unlatch and pull open the tray. To load the disc just close the tray by pushing it (gently) all the way in.

Is it possible to open the drive without removing the front cover that has plastic locks that can break?
I pushed the paper clip and the tray didn't open either

You don't need to remove the front cover. And the paperclip requires quite a bit of force because you need to overcome the latch inside. So you likely need to push a bit stronger. The tray will pop out a little - then you must pull it out, it won't open like normal!

But all of this stuff is well known and documented if you do a bit of research.
-
I pushed the clip with a little force until it locked at the bottom but I didn't push it anymore so as not to damage the device and the drawer doesn't open
regarding opening the drive just remove the 4 screws or do you need to remove the front plastic panel?
-
Typically you cant remove the drive's front panel unless you can open the tray at least a few cm. Remove the screws and the metal housing and see if it gives you access to turn any of the tray loading gear-train manually to open the tray.
-
I never had luck opening a drive sled with a paperclip. The clips are too soft and they bend before you can exert enough force to overcome the latch.
To push open a drive sled, you really need quite a bit of force.
Luckily, i still have an original opening pin that was included with a drive many years ago. That has at least double the diameter of a paperclip, it actually barely fits the hole. It flexes a bit, but does not bend.
-
i dont know how to identify a faulty belt but i will post a picture of the belt i took from my asus dvd drive obs. the tray does not open or opens 80 or 90% it only opened when I put the clip several times, drive is new
-
You can't tell a bad belt just by looking at it. With experience, you can stretch it and asses the condition of the rubber. e.g. if it doesn't immediately return to the original size when released or shows any signs of surface cracking or crumbling or looks uneven when stretched, its bad.
-
After I removed the rubber the drive slides normally through the drive but with rubber the drive does not open tray or the tray opens 90%
I still don't know whether or not to buy another rubber

Your country flag says Belgium, and I assume they have pretty good
consumer protection laws. Take it back to the seller and ask for a
refund or a new drive.

I suspect they might be from Brazil. They seem to have been banned for spamming identical topics/questions.
