External DVD Not Recognized

I have a Sony DWQ28A Dual Layer DVD burner that I have put up as an external drive attaching to a Firewire hub. Tne Mini does not recognize the burner at all. I have tried Disk Utility and there is no drive showing.
I have heard that Patchburn may be a fix but I have also heard that it works and then it doesn't. I have also seen that Toast Lite 6 should be used with this burner in Mac 10.X environments but I am hesitant to go there when the burner is not being recognized at all.
I would rather ask questions beofre I start downlaoding stuff that is not going to do the job.
Any thoughts?

I just got a reply from tech support at Sony concerning my problems with my DRX530UL burner (external DVD burner did not respond properly). They say that it is not supported for Mac at all.
They listed two drives that are supported for 10.2 and up: the DRX720UL/T and the DRX710UL/T. Note: the /T means Mac compatible! The drives with the same model numbers and no /T are NOT Mac compatible!
The 710 has a slower sustained and burst data rate, (16MB/s vs 21, and 66mbps vs 480mbs), and the 720 comes with Nero and Toast Lite.
Both drives do DVD-R/-RW, DVDR/+RW/+RDL/RWDL, etc etc.
My burner is several years old, and at $180usd, I can afford to upgrade to DL support.
I guess the moral of the story is that if Sony doesn't say it's Mac-compatible, it's pot luck.

External Superdrive not recognized

Hi
My internal SuperDrive died like a month ago with a CD stucket on it, that cant be ejected. It is a mechanical problem. I took it to a support service store (I'm writing from Lima, Peru by the way) asking for a fix or replacement and I figured out the it was much cheaper to buy an external drive. So I bought a OWC Value Line External DVD Writer (link below).
While I was waiting for it to be delivered, I was bored of all the ugly noises that my internal drive was making so I search for a way to disable it and I found a hint (link below) suggesting to remove IODVDStorageFamily.kext file from /System/Library/Extenstions
Today I got my new external drive but it is not being recognized. I have restore the kext file on the Extensions folder, I have repaired permissions, reboot a couple of times, etc... but neither my old internal drive or the new external drive are being recognized. It is like they dosent exist.
Any suggestions>?

Ok, backup your data*:
http://www.macmaps.com/backup.html
Dismount and disconnect any external data devices. If nothing works, just shut down and remove those devices.
Run the 10.6 installer. Boot from the CD if necessary by using the startup manager:
http://www.info.apple.com/kbnum/n106178
Then run the 10.6.4 combo installer.
Then check Apple menu -> Software Update for possible updates, but install them from http://www.apple.com/downloads/
Finally repair permissions with Hard drive -> Applications -> Utilities -> Disk Utility.

New Toshiba 3tb external drive not recognized at startup WIn 7

My new toshiba 3tb external drive (with wall wart power) is not recognized at start up (Win7). The message I get is that it is a USB storage device but can not be used until it is formatted (I already moved files to it). If I plug it in after start up it's fine and shows up as a toshiba storage device. I've used the 2.0 and 3.0 ports and it is the same problem (it has wall wart power). I have never encountered this problem with any other usb storage device (an iomega 1tb and a WD 500gb) always plugged in and recognized at start up.
Thoughts?

Please provide your complete model number of your system.
By doing so, we will be in a better position to provide you assistance.
Thank you,

WD external drive not recognized with 10.7.5 update

I've got a Western Digital external drive that was working just fine an hour ago, then I installed the 10.7.5 update and now my Mac Pro is saying that it's not recognized by the computer and asking if I want to initialize it. I went to Disk Utility and the drive itself shows up but no disc image. It's connected via a RocketU USB 3.0 dual hub, which has also worked fine and aparently still is (it's recognized in my system report). I updated my drivers for the USB 3.0 hub anyways but still no disc being recognized.
It's not a complete disaster because this is a backup disc, but I'd love to avoid having to back up all that data again (about a terabyte, which happens to be all my work files and iTunes files - it's a LOT of stuff). I also wanted to post in case this is some kind of issue with this current update, but I digress.
This is what my disc utility currently looks like:
The destination and source can't be the same (as is pictured) when doing a Restore, right? That accomplishes nothing but a blank drive, I'm guessing.
I also have Drive Genius 3 and tried to "scan" the drive several times, all of them producing failure to scan results. I could try a bench test on the drive, but as I've already stated, it was working fine an hour ago. I'm pretty sure it's the update, not the drive.
So is there any way for me to save the information that's currently on there or do I have to bite the bullet and re-backup all that data?
Thanks for any help here. Every time I think I know what I'm doing on the mac I get something stupid like this that I should know but don't. :-)

Wow, no help at all. Thanks, Apple!! Another stellar performance. That's the last time I ever install an update as it comes up.

External Drive not recognized anymore????

Just hoping I can find an answer about this from the community since I'm so inexperienced with the technical stuff pertaining to my iMac. For some odd reason, and I suppose it could just be that hard drives don't last forever, not sure, a My Book Essential External 3TB, USB 3.0 drive all of the sudden is not recognized by my iMac nor my MacBook Air. Literally overnight it just stopped being recognized by my apple computers. I had a whole bunch of data on it that I don't know how I'm going to replace it if I can't get an answer to this. The drives light comes on when the iMac system boots up in the morning, but it don't fire up (I think technically it's called initializing). Any help/suggestions would be greatly appreciated.

test with another computer even a windows computer should be able to detect it even if not mount it
because of the filesystem not being native supported
my wd my book ext 1TB usb2/eSATA/firewire died after 1-1/2 years after having problems spinning up a lot so I had to turn it on and off and on and off to get it to start
toke the box apart and put the 1TB hd in another external case and there it worked so suppose WD are better at making hd's then the external enclosure

External monitor not recognized (X200)

Hi,
I have an X200 with Vista
When I connect an external monitor (or projector) it is not recognized. Shift-F7 results in a message that no external monitor is detected. However, if I leave the monitor connected, put the system in standby and then resume, it recognizes the external display.
Any thoughts to how I can get it to recognize without this work-around? Thanks

I had the same problem. I think it's a vista device driver issue. Try this-
Power down your laptop. Plug in the external monitor. Boot the computer - it should default to the external monitor, and Windows should recognize it. Then, shut down normally.
Pull the monitor cable, boot your laptop regularly, reattach the cable, and give it a try.
It worked for me.

Are you trying to format your laptop? Since your external USB isn't working, you can still format even without the Recovery CD if:
You're still using the original Hard Drive that came with the laptop and haven't installed the laptop with a different Operating System before.
Also if your laptop didn't come with a Recovery CD when you bought it.
We can try doing System Recovery and I can give you instructions on how to do it.

Empty CD or DVD not recognized

Hi all
After weeks of burning CDs or DVDs without any problems I suddenly get these errors and I cannot burn anymore:
a.) If I load a CD-R I get from the Finder the message "Dieses Medium kann nicht verwendet werden, da es nicht erkannt wird." in english something like "Media cannot used because not recognized ..."
b.) Same message when loading a DVD-R
c.) If I load a CD-R I get from iTunes the message "Der Brenner wird gerade von einem anderen Programm verwendet." what means in english something like "Burner is used by another program ..."
The optical drive can read bought CD (Music) and DVD (Movie) without any problems. So iTunes or DVD-Player can play them without problems.
I'm not sure but could it be there was a bad software update? I remember some days/weeks ago I got a quite huge software update from apple related to the OS, iTunes a.s.o.
In other posts I've read that people had to exchange their optical drives but I don't think this is the problem here because reading runs without any errors.
Thanks for any support.

External DVD not supported?

Hi All
I bought a mac mini with a standart CD-RW/DVD ROM drive. I chose not to go for the SuperDrive as I have a external Freecom DVD-RW, which is Mac compatable. It works fine on my mac mini when I copy/back up large files to it.
I launched iDVD with the external DVD-RW plugged in, but still got the message "your mac does not have a Superdrive, iDVD will not burn DVD's". Essentially, I can create the DVD project, but not create a DVD. Is there a way round this? I know I can create an image (.img file), but how do I actually create a DVD movie from it?
Thanks

APE12, burned dvds not recognized, bd-r media does not recognized

I have a problem with burning with my PE12, I have a win7 64 bit PC, with following
BD Burner: HL-DT-ST BD-RE BH16NS40 from LG
BD-ROM: iHOS104
Problem 1:
=========
All DVDs I burned with PE12 are not recognized on my HiFi BD-Player, ONKYO-BD-SP809
the same DVD is NOT recognized on the BD-ROM in the same PC
the DVD is RECOGNIZED on the burner (see above) in the same PC
Media is 8x DVD-R, and ONYKO and BD-ROM of course supports this type of media and I used the same medias in the past (Verbatim)
Problem 2:
========
I thought, ok, so I burn a BD, I have BD-R media, which worked fine with pinnacle ...
I made a sample project (1min length) and try to burn it, but the burn menu shows the right device (F: in my case and the right name), but it tells me Status: there is no media inside! Allthough the media is inside the BD-Burner.
I am getting mad about it ... anybody can help me out?
P.S:
Burner, BD-ROM, ONKYO and PE are updated to the newest firmare/versions.
Best regards top the community

Premiere Elements 12 DVD-VIDEO on DVD disc that will not play back on the ONKYO player....
If you take the VIDEO_TS Folder from the DVD disc that will not playback as DVD-VIDEO on DVD in your player and look inside it, do you find a file named VTS_01_1.VOB or possibily VTS_02_1.VOB? If so, can you play that file back on one of your computer players? These are video files.
Can you take the Premiere Elements 12 DVD-VIDEO on DVD disc and play it back on the computer with Windows Media Player or VLC player?
Delete the Adobe Premiere Elements Prefs file.

and in the 12.0 Folder is the Adobe Premiere Elements Prefs file that you delete. It should be generated again after you open a new project. Work with Folder Option Show Hidden Files, Folders, and Drives active so that you can see the complete path cited. The try another burn to DVD, followed by play back on players of interest.
Any progress up this point? If no....

[CLOSED] CD/DVDs not recognized (hal-less KDE)

Hello everyone,
after the last system upgrade last week CDs and DVDs are not recognized when I insert them in the drive.
I'm running hal-less KDE 4.6 with udisks installed.
I removed hal after the upgrade, however the drive could not recognize the disks even when hal was running.
I searched the forum but haven't found any discussion reporting the very same problem.
Can anyone help me to debug this?
Thanks!

I had the same / similar problem. Just that given that I build my own kernel I thought this was what was causing it. That's why I rebuilded the kernel and enabled ISO and UDF modules in Filesystems. If you're using the standard kernel I have no idea what could be the problem.
