DVD-Ram disks won't mount on Dual 450 - help!

I've got a particular and pressing problem. I'm an audio engineer among other things. I have a lot of files archived temporarily on DVD-Ram disks from my old Dual 450. I have to retrieve some files pronto but suddenly the DVD-Ram disk won't mount. The drive spits out the disk as soon as I insert it. It will mount CDs but not these DVD-Ram disks. Please help. I need to back these up off of thse old disks. But more urgently I have pending sessions that require I get some files from these disks. This happens both under OS 9.1 and 10.2.8 the last revisions of this computer I did. But it used to work until a year or so ago.
I have so far repaired permissions, used Disk Warrior and sprayed around the dusty drive with compressed air. It seems that perhapos a mechanism is loose springing the disk out when it's not immediately recognized as a CD or DVD-R.
Help!

Probably your best bet is to dismantle the drive and try manually cleaning the lenses, which has made a difference for some users.
Other option is to replace the drive with a new one capable of reading (but not necessarily writing) DVD-RAM media. LG-4163B is one such drive, Pioneer DVR-110 can also read DVD-RAM. These drives are under $40 online in the US.

Disk Utility to format DVD-RAM disk

I have swapped out my Combo drive and installed an LG GSA-4163b so that I can burn, write to, DVD-RAM disks.
I have installed Patchburn which now allows me to burn CD's and all manner of DVD's but DVD-RAM disks will not mount.
DVD-RAM disk is recognized by Disk Utility but I cannot figure out how to make Disk Utility format the DVD-RAM disk. How do I do this.
Thanks,
Doug

Hi Douglas,
should work pretty straight forward:
* Open Disk Utility
* Select the disc in the column on the left
* click Erase (select Quick Erase if you don't want to zero out the disk)
* Click Erase to start the process

How to erase DVD-Ram disk

I have a half dozen DVD-Ram disks (from my now-dead DVR). They mount on the Desktop and I can see the contents (VRO and associated files). I am exploring the various Toast, Streamclip (etc.) options to play/rescue the files. Once that is done, how can I erase (and rewrite/reuse) the disks? Neither Toast 8 nor Disk Utility seem happy with formatting/erasing this media. Any ideas?
~ Keri

Ah,... makes sense. Thanks! And here's what it says [below].
So, it seems to say I cannot "erase" ... but I can "overwrite" (??), which is splitting a hair finer would have occurred to me.
Okay. Then, how would I "overwrite" the files -- what application could I use to do this? Toast? Other??

DVD+R DL won't mount...on 3 different drives!

Yikes!....Help!...I'm really stuck....
I've read a lot of the posts here regarding DVD's that won't mount and thanks in advance to those who've offered help. Hope you have some suggestions for me. Here's the deal.
About 4 months ago, the disk, a Memorex DVD+R DL, was successfully burned on my G5, using 10.4.11 for burning. And I was able to mount and read it a couple of times. It's a data-only archive disk of old files.
Over the past month, I've acquired a MacPro 2.8G 8-core (10.5.6) and a MacBookPro 2.61G Core Duo (10.4.11). And this disk will not mount on any of these 3 machines...not the MPro, not the MBPro and not the G5 that it was originally burned on! All 3 machines yield the same result...they kick the disk back out with out any messages..."error" or otherwise. There doesn't appear to be any significant scratching or degradation on the disk.
I've searched the net for a "Mac DVD data recovery" program but;(a.) haven't been able to find one....they're all PC and (b.)don't really see how any software app could "deal" with a disk that won't even mount!
I've had a look at the "upgrade the firmware" options, but it would seem strange that the firmware would be the problem on all 3 different drives.
I'm down to contacting a Pro Data Recovery company, but that'll be expensive!
So any and all suggestions will be HUGELY appreciated!
thanks,
b myers

The usual problem with Memorex DVD's of any format was they didn't burn period, so well done getting one to burn, AND a DL no less. I would try an external DVD burner from LaCie (or LG which makes a good USB one), or even a Windows box to see if anything can read it. A PC with EZ CD Creator or Nero could image and burn on a decent brand of DL (e.g. Verbatim) or even a USB drive.
Cheaper alternative is a 2nd non identical brand drive in the mac Pro, as they do take two.
Diskwarrior is not an option for something that isn't seen and thus is unable to be mounted by the filesystem.

DVD-RAM disk/ReadDV!- how to get into imovie

Hello
I have a dvd-ram disk with home movies on it, transfered from VHS. I want to get it into imovie to edit. I have DVDxDv. DVDxDV doesn't recognize the disk and the disk will not import into imovie. I read somewhere to get ReadDV! by software architecs. I did and installed corectly and it still isn't doing anything different that what was happening before I bought the software. Mac OSX opens the disk and sees the file, but when I click on the .vro file it asks which application I want to use to open it, and when I click on ReadDV it goes to the install folder with nothing lit up to use as an application. imovie is not lit up as a choice to open it and neither is DVDxDv. Tech Support at Softarc is gone for the day, hasn't answered emails I sent 2 days ago and I'd like to work on this over the weekend. THANK YOU!

I downloaded MPEG streamclip and it does convert, but you have to buy a download from apple in order for it to finish a conversion. Thought you'd like to know. Here's what the user guide says: MPEG Streamclip supports MPEG-1 video, MPEG layer 1/2 audio, AC3/A52 audio and PCM audio. MPEG-2 video is supported in conversions, but for playback and export you have to buy the MPEG-2 Playback Component ($19.99) from Apple." It's never easy, is it?

System disk won't mount

Hi folks,
I have a Mac mini running 10.6.8 Snow Leopard. I'm having problems with iCal, so I erased the program and its Library support files, and tried to reinstall from the system disk (which is 10.6.3). The machine won't mount it, just ejects it after a while.
Is this normal behavior since the OS has been updated? It's new behavior to me. What would I do if I needed to reinstall the syatem?
Thanks,
Eric

Run the combo 10.6.8 update. If that doesn't work, get your PRAM battery replaced. If that doesn't work, get your optical drive cleaned and see if the disc inserts then. If that doesn't work, but other discs do work, then I would call AppleCare to get replacement original discs. If they don't work, then I would have get an external DVD drive from http://www.macsales.com/ and see if the disc will work from them. If that dosn't work, bring it in for service to find out what is wrong with it.

Help -- System disk won't mount

Hi folks,
My mini: Intel Core 2 Duo 2.4Ghz, ID Macmini4,1
System: 10.6.8
I need to restore my iCal. It's broken: won't give me recurring event alarms. I'm trying to run my System Disk and it won't mount, the machine just rejects it. Same with the Applications Disk that came with it.
The System Disk is 10.6.3 and the machine is now running the fully Updated version.
Help, please, this a business computer and I need iCal back.
Thanks,
Eric

External disk won't mount after 10.5.7 upgrade

Hi,
I know there's problem with Buffalo external HD; mine is Lexcron 3.5'' external case and it won't mount neither. I tried PRAM restart, and if I go to Disk Utility and try to repair, it gives me the following message:
Verify and Repair volume “Dirty Hary”
** /usr/local/bin/ntfsfix has been disabled because of volume corruption issues.
** If you still want to try fixing your volume, use /usr/local/bin/ntfsfix from the command line...
Error: Filesystem verify or repair failed.
It worked with 10.5.6 and it still works with Win XP (it's NTFS format).
Is there something that I can do?
Will this issue be solved in Snow Leopard?
Thanks in advance for any kind of constructive info (I've already read threads with Buffalo issue, but I didn't find any thread giving a solution).

Hi V.K.,
Thanks for your response, can you provide some more details?
OS X has very limited support for NTFS. you need to repair the drive from windows.
How do I do that? I mean the disk works normally in Win XP and it worked normally in the previous OS X version. Btw. I've also installed NTFS-3D which allowed to write on the disk and search from spotlight (of course when it was mounted).
run chkdsk in windows and see if it finds any errors.
http://support.microsoft.com/kb/315265
it can also be that the problem is caused by ntfs-3g which is known to have a number of bugs. you can try uninstalling it or plugging in the drive in a mac without ntfs-3g installed.
there is no "issue" to solve.
Well if it worked in 10.5.6 and it works in Win XP and it doesn't work in 10.5.7 I am tempted to say 10.5.7 has an issue.
the fact that you have a problem with one drive on your particular system doesn't mean there is a problem with os x in general. an issue is when all or at least many people have a problem, not one.
furthermore, NTFS is a proprietary file system of Microsoft with closely guarded secrets about its inner workings which is why it has very limited support on other types of operating systems. apple is under no obligation to provide ANY support for something like that. programs like NTFS-3g are essentially unauthorized hacks.

DVD-DL disk won't play on my iMac G5

I am having a problem playing a DVD-DL disk on my iMac G5. I burned it on a Windows computer, and it works there, but then I put it into my iMac G5, and it spits it back out! I also tested it on an older iMac G3 and it works on that as well! WHY WON'T IT WORK ON MY IMAC G5!!!! Anyone have any ideas?

Most likely Boot Camp has nothing to do with it. As you mentioned first try a restart when you can, if the doesn't help I would reset the nvram and pram and finally reset the smc. If that doesn't help you may have a hardware problem.

Hard Disk Won't Mount; Lion Wants To Initialise It - Please Help!!

Greetings All,
Disk issues! Help! Ok, I have an external RAID box (Sonnet 8 Bay SATA) with 4 pairs of RAID 1 drives. One of the pairs, 3Tb Hitachis, all of a sudden won't mount on OS X Lion. Everything was working fine, tried to save something to them, Mac refused, I restarted and the other three pairs show up, but the 3Tb Hitachi pair don't. OS X gives me the message that "The disk you inserted was not readable by this computer". I've restarted the Mac and Sonnet box several times, checked that all drivers are up to date and reinstalled anyway. Have also taken the two drives out and tried to get them mounted on my Mac Pro or MacBook Pro using a FW800 dock without joy - always get the same message mentioned. Disk Warrior won't even help as when the Hitachi 3Tb is plugged in via the dock, the program hangs when it's scanning for disks. Although all the data on the drives is almost definitely backed up, I don't want to initialise / format the disks as there is a chance some video files aren't and also it'll knock FCP X as this was the primary drive where Events and Projects are stored.
Any suggestions would be thoroughly appreciated :-)
Cheers,
Edmond

Hi,
Both drives physically are working (both bought together several months ago). The Sonner RAID software shows the RAID pair as ok and doesn't report any issues or errors - it sees both drives and the RAID 1 is 100% fine. So, as far as teh RAID box is concerned, all is well and there are zero issues.
When I try plugging the drives in seperately using a dock, neither will mount and give the same error message :-(
The issue seems to be at a data / OS level. Biggest initial problem is I can't mount them to check :-(

Installation Disk Won't mount

I am trying to install Photoshop Elements 10 from the DVD installation disk. Why is it being ejected before mounting? Other disks mount fine.

It's possible you have only a CD drive. Apple has an exchange program to swap your DVD for CDs.

Hard Disk Won't Mount Volume

I have a hard disk that won't mount. It was previosly part of a software mirror RAID. The raid was degraded, so I tried to rebuild the second raid mirror. THis failed, and now the master won't mount either. In TechTools, the drive is reported as being fine, but the volume still won't mount. Any suggestions? This is really setting us back a bit.

OS X 10.6.6 Snow leopard.
Hi there, I have been experiencing this problem on and off with various media types (originally I had issues burning to any disc - cd or dvd- I upgraded to Snow leopard, and the problem was fixed).
Now i'm having issues READING home-burned DVD-R's, DVD-RW's ( I avoid using DVD+R's). Commercial dvd's load fine. I can burn to blank DVD fine. I have cleaned the internal DVD drive with a VCD cleaner, and tried resetting the SMC (http://support.apple.com/kb/HT3964).
I use an LG dvd recorder at home. The discs I use are SONY DVD-R and DVD-RW. These play without error on the LG dvd player.
However when I try to load the burned discs into the mac, the drive makes a whirring sound and spits out the discs within 10 secs. These are new discs with no scratches etc. I have tried setting the CD&DVD system prefs differently (opening the dvd in disk utility, finder etc) to no avail. I tried both finalizing the discs and un-finalizing them on the DVD player.
This is driving me nuts as I am a film student and need to access my burned dvds!
note: I recently had my computer serviced in the last 6months as the hard-drive failed (I live in Christchurch, NZ and the computer was damaged in the Sept 2010 quake). The comp was relatively undamaged in the more recent Feb 22nd 2011 quake, but because of the shaking, could there have been substantial damage to the internal disc drive in this case??
any help would be greatly appreciated! Cheers

Not sure what else may be the cause of the issue; but if there's
a chance of other hardware damage after an earthquake, it
may be wise to have someone check over the computer.
{I've asked this post be moved to the Intel-based iMac forum, yet the issue
is likely a generic one not limited to a build model vintage of computer. My
name's avatar is of the representative PowerPC iMac G4, of this forum area.}
For general disc burning, I use a small free-ware utility that makes it clear
what I may be getting; of course it makes quick work and the other methods
function correctly on my Macs... see http://burn-osx.sourceforge.net/ and use
it with the setting for it to make discs that will work in Mac + PC. Worth a look.
Good luck & happy computing!

Blank DVD-R's won't mount even though compatible with system

Trying to copy just a couple photos onto disc for a resume. Blank DVD-R will not mount on screen. They are accepted then rejected. Old DVD-R with information WILL mount, as well as CD-R's (audio). Using a fairly new MacBook Pro. Have checked HELP sections and computer system is compatible w/ DVD-R. So the disc drive(?) works but something that has always been very simple to do is not working. Am I using the wrong DVD? Have used this in the past so I'm confused. Any suggestions much appreciated since I need to get this done & mailed off ASAP. Thank you!

Once in a while few blank dvds may go bad.
Try to clean them or try a different batch.

Disk won't mount - Unknown USB Device (Link in Compliance Mode)

I have an HP Envy DV7 (dv7-7243cl ) with Windows 8 Pro x64. My Western Digital 2 terabyte My Book USB3.0 external drive periodically won't mount ( sometimes it will, sometimes it won't). The drive has its own power source.
When this happens Windows device manager shows - Unknown USB Device (Link in Compliance Mode). This can happen if the system is up and running and I plug the drive into the USB port or on system startup where the drive is already plugged in.
Any clue how to fix this?
Other details:
Intel(R) Core(TM) i7-3630QM CPU @ 2.40GHz
12 Gig memory
Intel(R) HD Graphics 4000
System board 181C 52.24
Bios F.26

Well, the problem is that - as outlined in one of the articles I linked to - some USB devices will not work in Safe Mode; that may have to do with the fact the Safe Mode is only meant to be a troubleshooting tool, not a regular way of booting up. Did you have the USB devices attached while upgrading to 10.6? That would also be a problem - I unplug everything except keyboard and mouse.And, did you repair permissions after the upgrade? If not, do it now.
And, the other problem is the fact that you wait 1 - 2 years before addressing the issue; when you had it in for the last repair and it still exhibited the same problems afterwards, you should would have taken it back, possibly with some screenshots, exact notes of how/when/error messages, etc. and insisted on having it fixed or replaced.
So, I'd run the Apple Hardware Test (after you make sure that you have a complete backup) - instructions here:

Report back with whatever messages you wind up with.
