Store optical discs in room with dehumidifier?
 

the air dehumidifier device with compressor used in the room is good for long-term storage of DVD and MDISC optical media?

You need to attached images to forum posts directly, not hotlink.

Yes, dehumifiers help. That's what is done at various libraries and archival facilities. However, be sure to select the proper level of humidity, not enough humidity can be as damaging as too much humidity.

Here are pictures of the dehumidifier that uses a compressor and
Green gas is good or bad for CD and DVD and electronic devices?contains options 40, 50, 60%

I'm not a dehumidifier expert, but those seem good to me. At very least, I'd assume a competent unit for a small/home space. That appears to be not too small, not too large.

For something like this, I'd read up on dehumidifier models at Consumer Reports.

I bought this dehumidifier but I know that they heat the air but I don't know if it heats too much or it heats little, if it is too much it is harmful and electronic and optical discs

To conserve CD and DVD optical discs The dehumidifier is good because it reduces and controls humidity, but it increases the temperature of the environment by 2 or 3 degrees, will this temperature increase harm the conservation of optical discs and also electronic devices? without the dehumidifier here where I live the temperature varies from 30 to 35ºC

Then also buy an air conditioner.

My room is not completely closed hermetic to use air conditioning
I have to choose between dehumidifier or air conditioner because both are expensive and consume a lot of energy
I also can't break the wall to install the air conditioner

What do you recommend me? I'm confused but I thought about the dehumidifier but it increases 2 or 3 degrees of temperature it makes a lot of difference in the conservation of the DVD and electronics

portable air conditioning also has a very large size and does not have a reservoir

For small spaces, portable air conditioners are about $275.

I actually looked into this, for cooling an outdoor workshop, during the hottest spring/fall days. (Summer is way too hot to even bother out there, unless at night.) Still a thought, 2021 expense.

my room measures 37m3 is not completely closed, the air conditioning has a large size to put in the room the dehumidifier measures 56x37x26 with the air conditioner does not have a reservoir

What is the recommendation?

Is it true or false that dehumidifying devices are used in filing rooms even though they know that dehumidifiers can increase the room temperature by 2 or 3 degrees

The dehumidifier used in a filing room is not in the filing room. It is part of the centralized HVAC system. The filing room will be the same temperature as the other rooms.

the room temperature without the dehumidifier is 29-32 degrees with high humidity with the dehumidifier the temperature has an increase of 2 to 3 degrees and low humidity, is this good for filing?

What color is the dehumidifier?

January 15th.

Plus 300 degrees.

no, 300 plus is model name

This thread gave me some early morning chuckles. :laugh:

Good? Probably not.

Read about humidifiers at archivist and librarian sites. Most probably just discuss RH% and temps, and that's what you need to know.

The humidifiers in archive facilities will not be *in* the room, but rather built in, so that heat generation is vented outside. This is no different than A/C at broadcast video facilities, or datacenters. You don't vent heat into the same room being cooled. A de-humidifier will be part of A/C aka HVAC, as you don't want to vent cold air back out.

That said, I've had humidifiers / dehumidifiers in my home. But I also have A/C and heat regulation.

In filing rooms do they use these dehumidifiers similar to my device?

That exact device is used in the Library of Congress to store the original Declaration of Independence.

Is putting the dehumidifier to keep humidity at 60% good for long life of DVD optical discs? Is 60% RH good for DVD optical discs?

Given that you've stated you've been burning your discs from a hard drive with bad sectors and claim that you're unable to get the original files to verify the integrity of the data on those discs, all your efforts to extend the life of those discs is pointless.

If your discs are bad because of corrupted data copied to it, they can last 50 years and you'll still have the same corrupted data. Spend your time and money on getting a known good copy of your files, copy the files from the discs to your hard drive and and start testing the actual data on the disc against the verified good copy on your hard drive. If you can't/won't do that, as I said, your disc preservation efforts are pointless.

Only after you've verified the integrity of the data on the disc, not the disc burn itself, start thinking about how to best store and preserve your discs.

Taking a step back, remembering lordsmurf's comments about a possibly bad backup is better than none. Your quest isn't completely pointless, just largely so until you can verify/test/restore your data.

Do HDDs have any automatic technology to reallocate and isolate bad sectors?

Asked and answered multiple times in your other thread.

Do bulletin board forums have any automatic technology to isolate repetitive questions?

Yes. But only if you access them in a fungus free room, enclosed in a bag with silica, inside another room, with 2% hydrochloric acid in the air, with 30-35% humidity and a dehumidifier! :D :screwy:

I don't generally cross-post between forums, but another conversation, on another site, was spawned from this one.

And I want you to especially pay close attention to my post here:

https://forum.videohelp.com/threads/...e2#post2598403

The person in this thread, our OP gamemaniaco, is (mostly?) wanting to retain backups of games. However, as I point out there, longevity of the media isn't the entire equation. There is longevity of the usefulness of the data to consider.

For example, I have games dating back to the mid 1980s -- CGA, EGA (Hercules card required!), 5.25" floppy copy protection -- that are 100% useless now. I have to have a cracked copy to even play, because fat chance finding a working 5.25" drive. The file was not copyable, so no image. Sierra is infamous: http://agi.sierrahelp.com/CopyProtection/index.html

There are many, many issues with old data. Locked to OS, hardware (sound cards, graphics cards, etc), CPU, even discs. Often related to copy protection, but not always.

So unless the content is truly historical documents in common formats (PDF, JPEG, MPEG), then the need for decades-old backups becomes suspect or moot.

What idiot stated that thread at Videohelp! Oh yeah... *raises hand* :rolleyes:

Thank you lordsmurf, lordsmurf, lordsmurf for your contribution. I think the thread has run it's course, with some really good possible solutions and your post is a great coda to it!

@gamey. No, I won't answer any questions about how to check the data on your discs. All the best answers are in that thread. Also, I'll *gulp* thank you here for making me think about actual data verification, NOT disc readability on burned discs.

Sometimes seemingly stupid conversations can spawn good discussions. :congrats:

... though I didn't consider that thread, or this thread, to be stupid.

Did you just compare me to gamey!!! :eek: *sniffle*:D

That just wants to make me want to hold my breath and turn blue until you apologize! Oh, I always forget, you'd like that!

Luv ya and always truly appreciate you. You old grouch! J/K!

I put my dehumidifier to keep the humidity at 50% and it does that but in the other hygrometers that are in the same room the humidity is 61-68% higher, which is the next recommended? my discs are stored in this room
