Comp won't recognize Mini DVD-RW

My computer won't recognize mini DVD-RWs using my external DVD drive (Plextor PX-716UF). It will recognize mini DVD+RWs. Plextor's support told me that the device is picking up the disc, it is the mac that is the problem. Anyone know of a fix?
Please help, my newborn baby's videos are on these discs.

Welcome to Apple Discussions!
The first question is, how was the DVD-RW formatted? Was it formatted on a Mac? If on a PC, was it formatted ISO-9660, or UDF?
If the latter, you may need to get http://www.softarch.com/us/products/rdvd.html
to read the disk.
Based on this website, it looks like they are 5 years behind the time and haven't heard of Mac OS X yet:

Verify with them it usable by 10.3. A firmware update may be needed.

My uMBP won't recognize recordable DVDs, can't burn

I have a early 2009 uMBP that won't recognize burnable DVDs. I originally had heard that it might have been a problem with cheap media disks, so I purchased another brand and have not had any success. My computer won't even recognize them when I insert them into the drive. I am getting errors from Toast as well as iDVD. The finder window also doesn't open asking me what I want to do when I stick the burnable DVD into the drive like it normally does. But I am able to play CDs and DVDs without any problems. Any advice is appreciated!

Thanks for the help so far guys. Here are answers to the questions that have been asked so far:
I have tried using Sony DVD+R, Windata DVD+R and TDK DVD+R.
I looked in Sys Prefs and they weren't set to ignore.
Here are the specs from system profiler:
MATSHITA DVD-R UJ-868:
Firmware Revision: KB19
Interconnect: ATAPI
Burn Support: Yes (Apple Shipping Drive)
Cache: 0 KB
Reads DVD: Yes
CD-Write: -R, -RW
DVD-Write: -R, -RW
Write Strategies: CD-TAO, CD-SAO, DVD-DAO
I tried the Windata disk again, and low and behold, it actually burned. But why didn't it recognize it the countless other times that I tried previously? I also just noticed this, but the system profiler says that it only will burn DVD-R and DVD-RW, not R/RWs. That's crap. My old MBP used to burn them all. Could the reason that it hasn't been working be because I have been using +Rs, not realizing that my computer says that it will only burn -Rs? And if so, how did it just burn on the +R if it only says it will burn -R?
I am definitely taking it to the Genius bar, but I definitely want to make sure that I have an idea of what is going on before I go in there. I have a history of not being able to replicate problems once I get to the genius bar...

Boot-camp assistant won't recognize my DVD-RW

So I have put a DVD-RW on so it could burn the Windows 7 to my DVD. I've seen a lot of answers to this question but it doesn't quite work.
I've a iMac 21' and tried to do this quite many times. What I do is I put the DVD in, start installing and then it automatically burn the DVD for me, but after I chose the partition for the Windows it won't install it further and gives me a error about my DVD is not inside and it takes a few seconds for it to recognize the DVD, but I've been waiting for a long time. Any solutions?

The "lot of answers" all usually have one thing in common:
Burn Windows 7 or 8 ISOs are the slow 2x speed possible w/ verify.
Anything else with using Disk Utility to do the burn or even BCA do fail.
Copy the ISO to your disk and try using that to write the ISO to (another) USB device.
Instructions for the Air: https://support.apple.com/kb/HT4407
download a free iso burning program for Mac (we used SimplyBurns Mac).
That program runs you through the necessary steps to properly burn the iso file you need.
After doing so, Bootcamp recognized the installation file and everything worked as it should.

If for some reason you downloaded Windows from Microsoft instead of buying a package with a disc, you need to download the ISO version and burn it to a DVD. See this article on downloading the ISO:
http://www.mydigitallife.info/windows-7-iso-x86-and-x64-official-direct-download -links-ultimate-professional-and-home-premium/ (Make sure you choose the ISO that matches the version you bought).
Here's instructions on burning an ISO with Disk Utility:

Step 4: Install the Boot Camp Drivers for Windows
After installing Windows, install Mac-specific drivers and other software for Windows using your Mac OS X installation disc.
The Mac OS X disc installs drivers to support Mac components, including AirPort,built-in iSight camera, the Apple Remote, the trackpad on a portable Mac, and thefunction keys on an Apple keyboard.
The Mac OS X disc also installs the Boot Camp control panel for Windows and theApple Boot Camp system tray item.
To install the Boot Camp drivers:
1 Eject the Windows installation disc.
2 Insert the Mac OS X disc.If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
3 Follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed WindowsLogo testing, click Continue Anyway.
Windows that appear only briefly during the installation don’t require your input.
If nothing appears to be happening, there may be a hidden window that you mustrespond to. Check the taskbar and look behind open windows.
Important: Do not click the Cancel button in any of the installer dialogs.
4 After your computer restarts, follow the instructions in the Found New HardwareWizard to update your software drivers (Windows XP only).
5 Follow the instructions for any other wizards that appear.
6 Check for updated Boot Camp drivers by using Apple Software Update or going to www.apple.com/support/bootcamp.
If You Have Problems Installing the Device Drivers
If it appears that the Boot Camp drivers weren’t successfully installed, try repairing them.
To repair Boot Camp drivers:
1 Start up your computer in Windows.
2 Insert your Mac OS X installation disc.
3 If the installer doesn’t start automatically, browse the disc using Windows Explorerand double-click the setup.exe file in the Boot Camp directory.
4 Click Repair and follow the onscreen instructions.
If a message appears that says the software you’re installing has not passed WindowsLogo testing, click Continue Anyway.
If you need to reinstall specific drivers, you can install one driver at a time. For example,if your built-in iSight camera isn’t working, you can reinstall just the iSight driver.
Individual drivers are in the Drivers folder on the Mac OS X installation disc.
To reinstall a specific driver:
1 Insert your Mac OS X installation disc.
2 Quit AutoRun if it opens.
3 Using Windows Explorer, locate the driver that you want to reinstall.
4 Open the driver to start the installation.

Windows 7 Professional XP Mode won't recognize internal DVD or external USB drives

Windows 7 Professional XP Mode - won't recognize USB external drives or internal DVD drive
I recently purchased a new Toshiba laptop and ordered configured with Windows 7 Professional so I could use XP mode for some older programs. The Virtual Mode and XP mode work ok, but the computer will not
recognize any external USB storage drives or the internal DVD drive. This prevents me from saving and transferring any file that I work on in XP mode.
,I also tried to copy and paste the file from XP Mode over to a document file to 7 Professional Mode, but it won't allow that. It also will not recognize any printer when in XP Mode,
so I can't print out the file either.
Basically, I have no way to store or move a file out of the computer when in XP Mode.
Does anyone know what I need to do so that the computer will recognize the USB drives and internal DVD drive when I am running in XP mode?

Checked these ?

IMac G5 won't recognize firewire DVD burner

Hello, all! I just purchased a LaCie+/-RW DVD drive (FA Porsche design) with firewire. From my first attempt to hook it up, my computer won't recognize the device. System profiler shows the firewire ports listed (400 speed) but the DVD drive doesn't show up either in profiler or on the desktop. I have tried: 1.) Resetting PRAM. 2.) Resetting SMU. 3.) "Resetting" the firewire ports in the same way that others have been advised to do in this discussion thread. 4.) Switching the firewire cable to the other firewire port. Yesterday I took the DVD drive to another Mac (G4 Tower) and it worked beautifully, so I'm certain that the cable, brick, and the drive itself are fine. Any ideas? What would be my next step to take so that I can burn on DVDs?
Also, if I picked up a firewire to USB cable/adapter, would that do an adequate job of transferring the data or would I be wasting my money?
Thank you in advance for your helpful suggestions,
Boring Teacher

Good morning, DP! I've never hooked up any firewire devices to this machine before, so I can't be sure that the ports have ever worked! If by "optical drive" you mean the mac's CD drive, it's built in. I have three external USB ports, two of which are taken up by the keyboard and mouse. The other USB port has worked fine for swapping in the occasional camera or iPod.
Thanks for the interest, I'll wait awhile before I take it in to a service desk!

Bootcamp won't recognize Win7 dvd

I have a late 2008 aluminum body Macbook (5,1), running OS X 10.7.4 and Bootcamp 4.0.3. I replaced the 160 GB Toshiba HDD with a Crucial M4 SSD and boot off that. The problem I'm having is that even though it allows me to create the partition, it won't recognize neither the 32-bit DVD I purchased nor the 64-bit DVD of Windows 7 Professional. I'm sure everything is up to date, so I'm not sure what the problem is. It'll just try to read it for a few minutes then spit the DVD out. Also, the download of the Windows support software seems to be taking forever. Any help? Thanks in advance!

If you can't even make the partition then something else is wrong. Even without a DVD in the drive Boot Camp should still create the Windows partition. That is done before it even looks for a Windows install DVD.

IDVD won't recognize second DVD drive.

The DVD drive in my G5 stopped functioning, so I plugged in a FireWire external DVD drive. The OS recognizes the DVD disk and the external drive, but iDVD does not. When I click the "Burn" button, it opens the drawer of the built-in (non-functional) DVD drive and tells me to insert a blank DVD.
There seems to be no facility for telling iDVD which DVD drive to use. Am I missing something?
Mac OS X (10.4.8)

Hi John:
You might want to try what Len Goff always recommends:
Create a disc image and then burn the DVD. File/Save As Disc Image...
http://docs.info.apple.com/article.html?artnum=164927
This will isolate any encoding/burning issues you may encounter. Once the disc image is created, double-click the .img and burn the virtual disc that should appear on your desktop, using Toast to burn the DVD. Disk Utility to burn the .img file. Usually, you can select a burning speed in Disk Utility.
There are variations to this process based on which OS X you are using...
Open Disk Utility (in Utilities folder in Applications folder), click on the virtual disc (maybe the .img) in the left-hand window. Click the Burn icon. A new window should drop down and your SuperDrive tray will open after clicking the Burn icon. Insert a recordable DVD. (Verbatim DVD-R preferred by me.) Click the Close button. Wait. Select a burn speed. If you hold your mouse cursor over the pop-up it says: "Select a slower speed to work around burn failures," so select 4x or slower for best results. Then click the Burn button.
-->If the virtual disk selection won't allow you to click the Burn icon, use the .img file instead. This may have changed in 10.3.9 and did change in Tiger.
Also, you can use DVD Player to play the virtual disk to check your iDVD project before burning to DVD. Launch DVD Player. File/Open VIDEO_TS (Open DVD Media... in Player 4.6). Find the VIDEO_TS folder and open that. (The audio folder is for DVD-Audio disks.)

My comp won't recognize my

I have my Zen docked and my computer won't recognize it. I have been under every system check on my hard dri've and it keeps looking for the device, but no matter how many times I unplug and re-plug it in, it is never recognized. Please help me before I throw it through a wall.

Megan, I may have a solution to your problem (and a lot of other people around here). I just found a post (not on this site) that informed me of a conflict between Creative's Software and Windows Media Player . I am a victim of this conflict as well.
I simply removed the Creative software. It detects fine in WMP. If you prefer to use CL's software, you can downgrade to WMP0 and take your chances trying to upgrade it again.
Here is a link to the original article I found so they may receive their just reward for figuring it out. http://www.anythingbutipod.com/forum/showthread.php?t=25477
I don't recall any warnings from Creative on WMP conflicts during the install process. Perhaps a re-release of the drivers with appropriate warnings are in order?

Burner won't recognize blank dvd

Hi,
I have an old cd/dvd burner I bought from best buy years ago. Tried burning a dvd and it wouldn't recognize blank dvd..it keeps saying "please insert dvd" even though there's one in the drive. It burns CD just fine. Plays DVD just fine. I have tried using SEVERAL other burning programs and still doesnt work. Please help.
Also uninstalled and reinstalled the drive several times...going crazy here.

Just to make sure, are you SURE it's a cd AND dvd burner? There are drives out there(I mention this since you said years ago) that were CD burners, with the DVD ROM feather.
If you like my post, or solution to your issue/question, go ahead and click on the little star by my name and/or accept the post as the Solution. It makes me happy.
I'm NOT an employee of Best Buy, or Geek Squad, though I did work as an Agent for a year 5 years ago. None of my posts are to be taken as the official stance that Best Buy will take on your situation. My advice is just that, advice.
Unfortunately, that's the bad luck of any electronic, there's going to be bad Apples... wait that's a horrible pun.

Mini won't go to disk setting, comp won't recognize.

I've worked through all the suggestions on the Apple site, and waded through some here, but can't find anything...
I do the "hold on/off, then press down Menu and Select", get the Apple sign, then "hold Select and Play" to supposedly get it into disk mode so I can restore it with software, but it just displays the unhappy iPod icon, then goes back to a half-display battery charging symbol.
It also isn't being recognized when plugged into my computer, so I can't update the software via iTunes updater.
Any suggestions? Thanks, folks.

Hi Christa!
Do you use a Mac or are you on Windows? I figured we'll tackle the "iPod is not recognized in Windows" problem first before we even attempt to place it in disk mode.
This is the link for Windows: http://docs.info.apple.com/article.html?artnum=61711
This is the link for Mac: http://docs.info.apple.com/article.html?artnum=60950
There's another way to set your iPod in disk mode, other than pressing buttons. Pressing buttons on my iPod never worked for me, I just couldn't get past the "Select and Play"..it'd go right back to the menu. Plug your iPod to your computer and then open iTunes. On the bottom right of iTunes there's an icon that looks like an iPod, click on it. Click on the "iPod" tab on top, and then click on the "Music" tab a bit below. Somewhere on the bottom of that window, there should be something that says "Enable disk use". Check that box, and then click "Ok".

Black MacBook won't recognize burned DVD+R

I'm trying to use some DVD+Rs containing video files that a friend of mine burned with my MacBook, but when I pop them in and hear the computer whirring and working as it should, nothing shows up on the desktop. When I press the eject key it ejects normally, so apparently it seems to recognize there's a DVD, but won't show me the contents. I know I have viewing CDs and DVDs on my desktop enabled, and I have used similar DVD+Rs with no such problem. Any help please? Thank you very much in advance!

Thanks for the reply Boece.
To answer your questions:
I have tried these recorded DVD+Rs in older PC laptops that have had little trouble reading them. I have also tried them in other Macbooks, which have responded similarly to my macbook when inserted.
I have played commercial DVDs, CDs, and recorded CDs in the drive and have had plenty of success. I have also played recorded DVDs that were made on computers with ease. The only type of media I seem to have problems with are DVDs not recorded on computers.
I do not have my own recorder, rather I had a friend record the DVDs for me so I don't know about other burn speeds (although I'm quite sure this isn't the problem as the DVDs do read on other computers)
When the DVDs don't read they simply eject. I never get an icon on the desktop or any error messages. The drive spins up and back down twice, then ejects the recorded DVD+R.

Comp won't recognize iPod?

Ok, so I went out and got an iPod nano. I had it for about 5 months, and now all of a sudden it just doesn't connect to my computer anymore. The computer does not recognize the device, thus making it impossible to put new songs
onto my iPod. I go onto google, and look up some iPod forums ( and try the downloads on the apple site, but the oly driver I saw was for a mac, the irony ) and from what I understand I am missing my USB mass storage driver(the drive used for iPods,is what I'm guessing). I have no idea where to find this or how to find it. I tried google, but who knows what is safe anymore on free downloads from google. Is there any downloads on the apple site for this driver or any other known site, or am I going to have to wait like a month till my moms friend can fix the computer?
I also have read the guides on the problems, but when you don't even have the drive on your list for the USB stuff, the guides don't really help much.
I have also re-installed iTunes AND Quicktime...I don't know what else to do.. =( this ***** so badly, cuz i just bought new songs off the iTunes store
P.S - here are my comps specs incase you need the info
Processor: 2.53 GHz Intel Pentium 4
Number of Processors: 1
RAM: 512 MB
RAM Type: SDRAM
Hard Drive: 120 GB
CD-RW: 40x (read), 10x (write), 40x (rewrite)
DVD-ROM: 16x
Operating System: Windows XP Home Edition

yah this problem is just killing me, bcuz i know what the problem is..but i dunno where to download the USB mass storage driver so i can't fix it...

DVD Writer won't recognize Blank DVD (Imation)

Hi
I have bundle blank DVD brand Imation but unfortunately my internal or external dvd writer would not recognize the disc. I have tried several times using Toast Titanium 6 and when i put the blank disc it says 'please put a blank disc. In fact, the disc i haven't use at all. Does it cause of my firmware or other related problem. Please help me. Thank you.

Hi M Faza-
Since it is two different drives the first step is to try a different brand of discs.
Are the discs compatible? Did you but dual layer discs when in fact you have a single-layer burner? Are you putting the disc into the drive with the correct side down?

20GB iPod/comp won't recognize/folder with exp point

Hey, hope someone here can help me out. I have a 20GB white iPod with the wheel and I am having some problems. First off, when the iPod tries to boot up, it shows the Apple logo, and then goes straight to a folder with an exclamation point. While it is doing this i hear it making a clicking sound. I have reset the thing 1000 times and it doesn't help. Also, my computer will not recognize it. iTunes won't see it, and when i go to My Computer, it is not shown there either. I've tried restoring it using the iPod updater, but that doesn't work because it cannot detect it. I have tried disk mode as well, but it doesn't detect it either. Any ideas of what I can do??

Ryan, in case you would like to save this cost, I suggest that you should be fixed it with a Mac computer.
Put your iPod in Disk Mode, connect it with a Mac computer (please find a friend who is using Mac),very likely it will able to be mounted and shows up on the Desktop. Open the Disk Utility and do a ERASE (format in MS DOS=FAT32). Once completed, re-plug it back with your PC, and a window pop-up mentions that your iPod can't be read and need to be formatted. Click "OK", then open the iPod updater and click RESTORE.
I have managed to fix couple of iPod with the same problem
