T61p cannot read DVD-RAM

I made some back ups last year on destop using DVD RAM discs. Now back on my T61p, the discs are not read. I tried a new DVD-RAM disc and find no way to have the drive recognize them.
Is this normal or is it possible that my drive is toast?

Hello,
In this Lenovo support article, it states some types of UDF-formatted discs require that additional Drive Letter Access software be installed when running older versions of Microsoft Windows. Could you tell us more about which version of Microsoft Windows was on the ThinkPad T61p when the DVD-RAM discs were created, what tool(s) were used to back up the files, and which version of Microsoft Windows is now installed on the T61p?
Also, were the discs readable at some point by the T61p, but ceased to be accessible?
Knowing the answer to these will be helpful in determining how to further troubleshoot the issue.

Satellite A20-130: SD R2412 cannot read DVDs burnt in certain optical drives

Hi,
I've got a Satellite A20-130 laptop, running WinXP and Ununtu Dapper in a dual partition. My 2nd laptop is not Toshiba one. When I burned DVDs (DVD+R) with my non-Toshiba laptop and played them in my Satellite it all worked fine.
However, when I bought a new optical drive for my 2nd laptop my Toshiba suddenly stopped playing the DVDs burnt in this new optical drive(I was using exactly the same disc brand and format as before-- DVD+R). I tried the old DVDs (the ones burnt in the laptop before the optical drive hardware was upgraded) and they can still by read perfectly fine.
This problem applies to both Ubuntu and WinXP. Support from 2nd laptop says this sounds like a firmware problem with my Toshiba. I updated the driver for my SD R2412 Toshiba optical drive (which, according to the file manual, seems to fix a DVD-Ram compatibility issue). Now the drive occasionally reads some of the new burned DVDs (after making loads of noise and waiting for ages), but more often than not I get an error message saying the device cannot be read because the format is incorrect or the device needs to be formatted.
This non-Toshiba laptop reads the DVDs it burns using the upgraded optical drive perfectly fine.

Hi
Satellite A20 is pretty old notebook model and after intensive usage it can be that drive is more sensitive. If all this happen occasionally there is no simply explanation why this happen.
I know it is pretty annoying but I do not see any magic solution. At the end you must test it with brand new drive.

DVD-RAM disks must be formatted first. Could that be the issue?

Re: SA80 Cannot Find DVD-RAM Drive

A client gave it to a backyard tech because the DVD drive wasn't working. Apparently he got it working, and formatted and reinstalled the computer - Thus leaving it without drivers. What's more, he formatted it badly, screwed up the MBR a bit.
Anyhow, I completely wiped the HDD, and got halfway through installing windows XP Pro before I realised that I was installing the wrong one for her key. Cancelled it, and the installer threw a bit of tanty - So when I put Home back in, it tried to boot up the pro installer off the HDD - It was just a big mess.
Blue screens and issues. So I popped in Vista, and used THAT disk to format the computer (As Vista was reading a driver error in regards to both disk and hard drives I didn't bother to install it, and simply used recovery console, and the words 'Format C:').
And now the DVD drive is not working again. Anyone with any bright ideas that will save me an aneurism?
It's not displayed under BIOS (But it's a laptop, so it might no be supposed to.),
And when I changed the boot order to go from disc it jumps straight to the disk drive - Which no longer has an OS, and thus informs me that BootMGR is missing. Went through PXE, and it can't pick up the drive either.
The drive does seem to be spinning, but then dies away.
I don't know how the previous tech solved it. I could rip this laptop to pieces looking for a broken cable, but I doubt that's the problem.
Info; Satellite A80 1.86, 1gb RAM, 60gb HDD. drive is a DVD-RAM. And it's a P006andsoonandsoforth.
So, any ideas?

> Update - Got the disk drive working again. I'm going to operate under the theory that the drive is sensitive and that the owner must have knocked it about some - As all I did was wiggle the tray a little bit.
Great! Thanks for this feedback

Cannot read DVD+R with GWA 4080M firmware AA26 (macbook pro 1.1)

Hi everybody,
I have a macbook pro 1.1 with a drive GWA 4080M (firmware AA26). Since a few weeks I cannot read anymore some DVD+R (Sony DVD+R media code D21).
1) One of these media burned with my other macbook pro (2.2 drive Matshita UJ-857D firmware KCVB) using the finder (so ISO9660,joliet,UDF and mode 1, booktype DVD-ROM) cannot be read on the MBP 1.1 - The same DVD is properly read on other mac or PC even on my old dell PC of 2003). I used the finder to burn it.
2) The very same media burn (data), burned using the finder as well, are read if burned by an other burner (Mac quad core, with SONY DVD RW DW-D150G). The disk seems to be similar (ISO9660,joliet,UDF, mode 1, booktype to DVD-ROM).
Actually the bitsetting (I learn what it was from wikipedia yesterday) seems to be done by default on mac (both of the burner).
3) A DVD+R (still same media) is burned properly on the MBP 1.1 with GWA 4080M drive, and readable everywhere.
4) The Matshita UJ-857D has not received the superdrive 2.1 update (if applicable, that seems to triggers problems). I experience no problem in burning or reading with this drive except this one.
I tried to reset the I repaired the permissions (there was nothing to be done anyway), I also reset PRAM and NVRAM (http://docs.info.apple.com/article.html?artnum=2238)
and SMC
(http://docs.info.apple.com/article.html?artnum=303319)
and it did not helps
Last point the problem is the same under windows (bootcamp) and mac!
I would be very grateful if someone has a suggestion to fix or at least!
Thank you in advance

my same problem..
how come we can't get an answer on this?

My G5 cannot read DVD-R, 4.7G discs

I know it's an older model with an older Superdrive, but is there anything that I can do any programs I can download that can change it?
I use a Dual 1.8 GHz PowerPC G5, loaded to the gills with RAM and memory.
Thanks,

Awrite, here's what i've done to reanimate my defunct DVD player. First i insert a DVD and as usual, nothing happened. Just testing, tried out a Jethro CD, worked fine. Ian back in the box, now with the DVD inside the drive. Silent as a grave. So, i run the dvd player software and the Toast Titanium. Ask for disk information, no CD in the tray, was the answer. Ok, open the tray, disc info. Answer: The tray is open. Close the tray in the keyboard. Well a this point i was annoyed because never an apple DVD worked properly for me (and i am mac user since 1988) and i never found a satisfactory answer regard DVD support from mother Apple who provide us with these magnificent machines but never follow the discussions to see if we users are happy. Well, i keep asking, info and open and closing the poor tray driving my anger in this catharsis when suddenly the Dvd player software started play the movie. So, i cancel the info in Toast, quit the program and watch finally the Dvd. I think i have irritated the drive so bad that it decided to wake up, it worked this time but i don't know about the next one. True story. Better Solution? External DVD burner.

Help needed! T40 DVD driver cannot read DVD

Dear Expert
My DVD driver cannot DVD. The DVD driver icon in "My Computer" does not show the name of the DVD and when clicked, shows "no DVD inserted".
But it can read CD.
Thanks very much for your help and advice in advance,
Cath

there is a possibility that the laser associated with the DVD reader is no longer functional, while your CD reader laser still is, as these two lasers are different.

HELP! Cannot read DVDs

Tried to read them with G5 and home DVD player, but getting error messages, DVD cannot be read!
BUT: My iBook G3 can read the latest burnt DVD!
What is happening?

Hi Fanny
Welcome to apple discussions. Have you recently switched brands of DVD. Tell us which types of DVD's you are using. Verbatim DVD-R Minus 4x is the media of choice and is what many will recommend on apple discussions.

Optical drive cannot read DVD-RW after burning?

All of a sudden my built-in optical drive (Matshita UJ-857) appears to have lost the ability to mount burned DVD-RWs. I'm using Sony 1-2x media which burn & verify successfully. Following the burn, the DVD-RWs show up on the Desktop and can be browsed in Finder. However, once ejected, the drive cannot mount them again - they spin up for around 30 seconds before being ejected.
Other media (DVD, DVD-R, DVD+R, CD, CD-R & CD-RW) work fine; DVD+RW requires 2~3 inserts before it mounts. I've done PRAM & PMU reset, same results. Is my drive failing?

I can view the same disk/photos on my old L300
There are any number of special so-called packet writing programs which create discs readable only by the same program. If you use the built-in DVD burning for Windows Vista (especially with Mastered format), that problem would not occur.
Burn a CD or DVD
So you should either reburn the DVDs using the Vista machine or copy the pictures to the new machine (probably over your network) and burn new DVDs from there.
When you post here, always tell us the full model designation of your computers. Which Satellite Pro L330? Which Satellite Pro C660? That way we can look up what your machines look like.

Cannot read DVD's on PC.

I have tried burning a few DVD's from my iMac G5 and the burn process seems to work ok. I can eject and insert the new DVD and all looks good. Now when i take this DVD to an XP machine there is nothing on it ? Is there anything i need to do when buring a data DVD to make it readable via a Windows Machine ?

when buring a data DVD
iDVD makes video DVDs, not data DVDs.

Cannot read DVD

It probably does not have to do anything with the software, but my MacBook Pro does not read the DVD. Any suggestions?

Try turning off the computer and shooting compressed air into the CD drive (use a compressed air can, or 60psi on a compressor.) Then turn the computer back on and try your DVD again. It took me 3 or 4 tries, but it eventually worked like a charm. (NOTE: If you leave your computer on while you do this, you may hit a shock switch, which will cause your drive to act "broken". If this happens, power off the hard ware and power it back on, and It should work again.)
Hope this helped!

Problem: DVD-RAM can no longer be read on MBP C2D

The "MATSHITA DVD-R UJ-857D" in my MacBook Pro C2D is said to have read (but not write) support for DVD-RAM media.
During the first few weeks of its lifetime, reading DVD-RAMs definitely worked. But now, no more, no matter what brand of media I try.
All other types of optical media continue to work as advertised (read and write).
I wonder whether this is a physical defect (but then why doesn't it affect other types of media?) or an issue caused by recent sopftware updates (but when I boot from an external DVD-drive using the very original MacOS DVD with no updates at all, why do I still not get read support on the internal drive?).
AFAIK there has not been any recent firmware update for this model. So what can be the reason? Should I let Apple swap the drive? Has anyone else observed the same issue?

Hey Grant,
thought you'd like to know my "cleaning the lens with a cloth" worked fine - uh... but for about three days only, then back to the same old, same old.
I'd originally slid a business card covered with a lens cleaning cloth (from my camera bag) to clean the lens, and although the cloth emerged mostly pristine, I figured it must've done the trick as the drive started working again.
So this time, I decided to go in deeper. I actually took the whole drive apart - case off, drive out, drive dismantled - and I had a long look around to see if any parts looked dirty or damaged...
I found just one thing - the small silver rod on which the read/write head travels (the servomechanism that moves up and down the disc radius as it reads/writes) had some 'oily gunk' at the point where the travelling-head's 'sleeve' met it - when I tried to move the head manually up and down the rod, it sort of staggered along. So I cleaned off the gunk with a cotton bud and then slid the drive-head up and down a few times 'till it seemed to run freely.
Put everything back - and fired up my Mac Pro. And the drive has been 100% fine since then - two whole weeks!
Maybe this time I've cracked it? (for my drive at least)

Optical drive supports DVD-RAM?

I have DVD-RAM tool on my laptop, model 129(with combo drive), but I don,t know whether my optical drive supports it or not. How I can know?
Also need some easy information about DVD-RAM.

Chances are if you have the software on your computer it has DVD-Ram. Here is basically what I found at a website trying to explain DVD ram and how it works. Hope this helps.
DVD-RAM (DVDRandom Access Memory) is a disc specification presented in 1996 by the DVD Forum, which specifies rewritable DVD-RAM media and the appropriate DVD writers. DVD-RAM media have been used in computers as well as camcorders and personal video recorders since 1998.
The term DVD-RAM is a misnomer; the name is based on the (erroneous) abbreviation for RAM, meaning "read-and-write memory" - the opposite of ROM (Read-Only Memory). However, RAM actually stands for Random Access Memory (computer chips) and DVDs inherently cannot use the random access method.
Compared with other writeable DVDs, DVD-RAM is more closely related to hard disk technology, as it has concentric tracks instead of one long spiral track. Unlike the competing formats DVD+R, DVD-R, DVD+RW and DVD-RW, special DVD burning software is not required to write or read DVD-RAMs on a computer. DVD-RAMs can be accessed like a usual floppy disk or hard drive.
Mac OS(Mac OS 8.6 or later), Linux and Microsoft Windows XP support DVD-RAM operation directly, while earlier versions of Windows require device drivers or the program InCD. The optical drives shipped with Apple Macintosh computers do not support DVD-RAM operation, but a third party DVD-RAM-compatible drive can be connected and used directly with Mac OS.

Reading dvd-r on Macbook Pro

Cannot read DVD-R on my Mac.... any ideas?

A brief update:
I dropped my computer off to FedEx on Thurs. evening (6:30 pm) and received it back on Sat. morning (8:30 am). That was incredibly fast!
Anyway, the following parts were replaced.
- ODD Super Drive (Symptom: Optical Drive Read/Write Data Error)
- Main Logic Board 2.4Ghz (Symptom: Sensors Test Failed)
- Optical Cable (Symptom: Drive Read/Write Data Error)
Moral of the story: if a Genius finds a "work-around" a the problem rather than trying to determine the actual cause of the problem, call AppleCare. Do not be afraid to speak with a Senior Manager (because, in my cause, the normal AppleCare technician didn't think anything was wrong.)
Thanks again for your all help.
Best,
