Those platters are beyond magnetically sensitive. Touching one, possibly direct sunlight, or being near a speaker is going to corrupt data on it. Without the protective shell of a hard drive case they're worthless, and at that point you're just carrying around a hard drive.

Just open your hard drive, then close it back up and see how well it works afterwards.

There is no reason to buy rewritable optical media anymore, we all know this.

I somewhat doubt it was perpetuated by data recovery companies. It's probably perpetuated by people tired of others coming in with broken HDDs.
>opening the hard disk kills the platters
Is obviously not true. There's air in there in the first place (with the exception of HGST He6 drives). Dust on the platters (can) cause bad sectors, which is a mostly recoverable error. It's not a good idea to open a hard disk anywhere that isn't a clean room but it can be done to, for example, fix a stuck head. However when closing it you should use a screw driver that clicks after hitting the right tension, something that most people don't have on hand, and you cannot reasonably trust the drive after having opened it in an unclean environment so it should only be done for recovery purposes.
>>
a burned disc might last 15-20 years in ideal storage conditions.

a hard drive is constantly at risk of failing outright. they'll last about 7 years in full operation; longer only if it is a storage volume, and even longer if you fill it up and discontinue using it.

i've yet to find out for myself if leaving a hard drive out of operation for an extended period of time actually damages data or not. it just seems like a FUD IT rumor to me but must have some truth to it.

if i were to back something important up i'd certainly trust a BD+R DL more than i'd trust a magnetic hard drive. at least i can make multiple disc copies on the cheap. (take this from someone who's trusty 500GB WD system volume failed on them just last night taking everything i couldn't be fucked to back up with it).

RIP in peace - my data 2007 - 2014
>>
>>43317484
Do not trust optical storage that you yourself write. It contains a light sensitive material and the simple act of leaving it in the sun can kill it really quickly.
If you need long term storage, you want CF cards or in the case of large amounts of data, multiple offsite backups from multiple live companies.
>>
>>43317484
if you're using optical discs for long term backups, you should consider using dvdisaster as well

it's a programs that uses spare space to augment images with additional error correction information

for example, if you make a 3G iso and plan to burn it onto a 4.38G dvd-r, you can fill in that 1.38G with extra ECC, making the disc far more resilient to damage (it can take more read errors without data loss)
>>
>>43317539
why on earth would you leave backups lying in the sun? they'd be in a case in a cupboard or something, not anywhere where heat and light can get to them
>>
>>43317576
It's not that any sane person would leave it in the sun, it's that a very small mistake can absolutely wipe out your storage medium. At some point someone might move it and leave it on a desk for a couple of hours 8 years down the road and your already fragile disk gets murdered. CF cards are much more resilient. Furthermore, as CDs have shown, they don't last anywhere near 15-20 years. Not even 10 years under normal conditions. I can't imagine DVDs are any better.

>tfw still rocking a ten year old hard drive that was once used in a server and had constant reading/writing for 4 years straight.
>>
>>43317702
>>43317744
LHC uses tape, because it is very resilient to errors, very fast to write, very fast to read, and stores a shit ton of data per $.
Just seeking on them is painfully slow, but for the LHC, it doesn't need to seek.
>>
>>43317744
I've never used magnetic tape, mostly because drives are ridiculously expensive, but I wouldn't trust it for a few reasons:
* It's uncertain whether you can actually read it back
* You might not even be able to get a drive to read it when you need it
Much like a proprietary hardware RAID controller, once it's discontinued your data is effectively at the mercy of that single point of failure. Using a couple of CF cards to, for example, back up your key to encrypted storage held by multiple companies will at least ensure that you won't see interface incompatibilities for the foreseeable future and also not set you back thousands of dollars.
>>
>>43317651
This was a 530MB drive in a 486 which kept producing "Seek Error Reading Drive C" messages at the DOS prompt, although I could also point out that it was almost completely full and that could have potentially caused problems as well. I had a 20GB drive die from crashing because the computer it was in tipped over while in use. Other than that, nothing in the way of outright drive failures.

There are hard drive recovery solutions...They cost around 1,500-2,000 dollars per drive but it's well worth it.
>>
>>43317381

This.

>>43317484
A mechanical hard drive is a solid option for long term storage when without power. Magnetic tape and platters suffer the least from bitrot/degradation, though are more susceptible to their environments. Under normal conditions, the only time a hard drive really suffers wear is when it is spun up or spun down or under constant read/write. When kept at speed (no power saving in use), the wear is minimal.

There's a reason there are holes with DO NOT COVER written next to them on hard drives, mainly laptop hard drives.
If you had a vaccum or whatever you retards are thinking the drive the head would fail to hover over the disk and it wouldn't work.
>>
>>43317899
They say it's better to set your hard disk to not shut off after, like, 30 minutes of use because powering up/down strains the drive mechanism. It works on the same principle of how stop-and-go driving is harder on your car than highway driving.
>>
>>43314983
The HDD is a carefully calibrated device with barely any tolerances. The distance from the read head to the platter is miniscule. The platter's mounting is carefully balanced so it can spin at high speed without issue. The servos on the read head are incredibly accurate.
Since touching the HDD platter damages it, you'd have to have a container, like a diskette, and then in order to make it work on a system of such loose tolerances you'd have to significantly reduce both capacity and speed.
Either that, or you make it all self contained.. oh wait, that's called a hard drive..
>>
>>43314983
optical discs are still attractive to some businesses because they do have a very long theoretical shelf life, lighter than a drive, and will use less electricity. not to mention, there is a certain amount of data security knowing that if an optical disc fails, you will lose 50gb, rather than 500gb,1tb, whatever if one mechanical drive fails.
also, promoting a technology and increasing the demand for it will lower costs of it in the long run.

i will try to recover it with a usb external drive hub first. the last time i had a drive failure was with an identical drive. it gave off warning signs of imminent failure by constantly refusing to spin up, making loud unordinary sounds, and disappearing from windows explorer, but it wasn't dead yet. i managed to get every bit of data off of that drive with the external hub, but with this other drive i'm not sure that method will work, since it failed outright without warning. could be a logic board failure, could be something more serious. i don't have the money or spare storage to be attempting recovery right now, so i'm not going to touch it until i do.

really the only things i want off of it are my years of documents, art and video projects, maybe some save games and my libraries if i can get the damn thing to read for an extended period of time. i foolishly never got around to backing up my data recently because my optical drive died.

you may have more luck using linux to read your drive. i had a drive that windows refused to mount, but linux + ntfs-3g mounted it fine. in copying the data to a better drive, a few files failed to copy and really slowed down the process to transfer about 800gb of pirated music, mv, movies, etc. i remember it taking about 10 hours, but i got most of it back.

Yes you don't want dust in shit in there, but to say your hard drives are sealed is just misleading. The fact someone got called out for (correctly) stating a hard drive can work with the top off strongly implied people were thinking it was sealed to the outside, which is completely wrong.
