My Brother has his Box on his desk and the DVD/CD drives are right at his eye level. The other day he was burning something on an Imation blank. The blank shattered and blew the front out of the DVD drive. The crap hit him in the face and even put some small cuts on him. He wears glasses so I didn't get in his eyes! I'm thinking that the drive failed and over reved the disk.

Re: CD and DVD Warning!
I had this happen to me, but the drive stayed closed. It ruined the DVD burner, but it was under warranty, and I got it replaced.
I think using cheap media is the cause of this. I think that I was using some Imation media too. -

Re: CD and DVD Warning!
Had discs crack from spinning too fast, not drive go crazy though. Maybe not to do with manufacturer but the weight and quality of the materials irrelevant of the metal film dye quality.
They don't really tend to make them like the old days when you paid £5 ($10) per CDR. That I know of. I hear America is a big place though (atleast you can fit a good few hundred maybe thousands of Englands into it) with lots of forgotten warehouses full of old goods. Heres hoping.

Re: CD and DVD Warning!
i had a CD that had a centimeter crack on the outer edge. for shits and giggles i put in in one of my drives to see if it would read anything. the drive spun up and then BAM!!!! the drive no longer worked. The CD was in three larger pieces and then a whole shit load of small pieces.
needless to say, i don't put known cracked discs in any of my drives anymore."Its all about the boom....."

Re: CD and DVD Warning!
I had a CD which I think was structurally weak (no visible crack though). I put it in my laptop, closed the drive door, and immediately heard a scraping sound. Took out the battery straight away to force power off the laptop, and used a paperclip to open the drive. The disc had cracked in two, and the two pieces were on top of each other still being gripped by the spindle!
Luckily, the drive didn't seem to be damaged - I was able to read another CD on it without trouble afterwards. Also, I'm glad it was a tray-load laptop drive. Had it been my new laptop (slot-load drive), I don't think I'd have been able to rescue the pieces without dismantling the entire thing!
I also had a similar experience with a CD-R disc that was slightly damaged and wouldn't read. At this time I didn't have a writer at home, only a reader. I put the disc in, nothing happened for a while then I heard the disc spin up to 50x speed (it was only a 40x drive!) I pressed the eject button, the tray opened, the disc came out still spinning - and flew across the room!

Re: CD and DVD Warning!
Close call may be worth installing a drive speed limiter if you use alot of disc media. Myself I would flash drivers to run maximum of 16x I feel not much return from higher speeds. The fastest I burn is 16x (CD speed) but if it's an important burn as slow as possible usually. Higher speeds with single laser drives is really just to sell goods not in your real best interest for either time saving or anything else (my opinion).Rubycon Rubycon RubyconComment

Re: CD and DVD Warning!
I have read some articles about this sort of issue and just about always the issue is with the media. The culprit most of the time are very small cracks, usually around the centre hole on a disk. As the disk is spun at very high speeds, the crack propagates across the whole disk and shatters! Interestingly, from what I remember, disks tend to shatter at around 52x speed for CD's. I am not sure what speed this is equivalent to in terms of DVD's.
I agree with Fizzycapola, burning CD's and DVD's slower is always better than faster. Now it seems like it may be wise to lower the maximum read speed of CD's and DVD's too (just one or two notches).Comment

Re: CD and DVD Warning!
This is the very reason CD burners faster than 52x don't exist, 52x is actually 10000RPM!
(There are faster drives but they use multiple lasers and thus the disc does not actually spin as fast as a single laser 52x drive)"The one who says it cannot be done should never interrupt the one who is doing it."Comment

Re: CD and DVD Warning!
That video reminded me of when I put a metal turntable platter on a sewing machine motor until at full speed, and then pushed it off. It spun across my basement floor throwing sparks everywhere, but didn't get enough grip to go very fast

Re: CD and DVD Warning!
I've always hated high speed optical drives. Too noisy, they shake themselves to death, and they have annoying lag. My favorite CDROM was my old 4X which responded immediately without needing to "spin up" first. I can't think of any reason I've ever cared about having a fast transfer rate at the expense of access time.
One time this discussion about projectiles came up in some other forum, I think it was in regard to 15,000rpm hard drives. I decided to calculate what the velocity would be if a fragment flew off, but it didn't sound very dangerous. As I recall it was slower than a cheap BB gun. I guess the eyes are more vulnerable though.Comment

Re: CD and DVD Warning!
I have had a pile of optical drives over the years. I think my main Sony Burner has a default mode in it for CD speed. It reads the CD's at 38X but if you hold one of the face plate buttons in for a few seconds it will kick it up to 54X. There is even a warning in the manual that disked that are less than perfect should never be spun up to 54X. With all this said, I have never kicked one to 54X as of yet. When I have to try and save a damaged disk I use my VOM-12E48X Dog drive. I also use my Nero drive speed thing to slow it down to 4X or slower. Now my Sony drive has been messing up for the past two months. I'm going to be replacing both drives very shortly. Plextors cost too much for this pig of a PC but there is something out there on the cheap that will do what I want. Blu-Ray is still out of the question because of cost, and the fact that both of my home players can't do Blu-Ray disks.

So I am trying to repair broken thunderbolt FW on X1 Yoga Gen 2. The EEPROM chip is WINBOND 25Q80DVNIG. I already do a back-up and erase. But when I try to wrote new FW, it was successfull, but when I tried to read it, it still blank. when I try to do a blank check, it gave me instant error in address 0. I already tried two CH341A, already did the 3.3v fix mod, using AsProgrammer, NeoProgrammer, Colibri, and CH341A 1.29. But the problem still occurred. What I did wrong here? Can anyone help me? Thanks in advance. Here is the log in Colibri :

I've got a Hanns.G Hi221 Monitor that works for a moment and then the display goes off but the power LED indicator remains on. If you power it off and back on again it does the same thing, it comes on and then the display goes blank. From a cold start it takes 10 seconds or so before the display goes blank but if you turn it off and then back on again after it already being on it goes blank a lot quicker so I'm assuming something is getting hot which is causing the display to go off.
I've uploaded a video of it happening on YouTube:

I have try with 3 different adapter
Dell adapter 40w - warning "Slow Charger" (charge rate 8mW)
Dell adapter 65w - warning "Slow Charger" (charge rate 8mW)
Power Supply Connected with BY-3200 (in bios detect 65w) - okay and no warning (charge rate 25000mW-32000mW)
i already tried update bios and update all driver but problem still persist....any idea to solve this?... -
Hi all, I’ve got a problem I hope someone can help me fixi.

Hello,
I am having a problem with a ASUS VH238T.
The monitor started by just going blank, but the integrated speakers, and the backlight worked. The OSD didn't pop up, neither did the messages of DVI No Signal, nor the Asus logo.
Turning off the monitor, and turning it back on made no difference. But leaving the monitor off for a few hours returned the monitor back to normal. The problem will eventually return after a couple of hours.
Today, it started exhibiting another symptom: the display started showing a white image, that didn't take the whole screen....
