Imac 24" dvd-drive doesnt show inserted DVDs randomly, only after reboot (?

hi
i am very aware of this problem as my powerbook G4 had the same issue,
although its not a big issue i am worring about.
when i insert a DVD sometimes, lets say a commercial Movie DVD, an older burned DVD from 2002 or 2005 or even 2006, my brand new imac 24" doesnt recognize the inserted DVD randomly, not every day, but on some days........
when i start harddisctoolkit, it doesnt show the dvd, too.
the drive spins a bit, then stays calm.
i use to reboot then, and surprise, its always there!
what is it please?
thanks

hi purepeter-
have you tried resetting the smc?? http://docs.info.apple.com/article.html?artnum=303446 have you checked for directory damage using disk repair?? http://docs.info.apple.com/article.html?artnum=106214

  • DVD drive doesnt show on my Satellite Pro A300

    Hello,
    I have just taken delivery of a Toshiba Satellite A300 running Vista Home Premium. I cant find the DVD drive when I goto Computer and likewise I cannot access the disk drive for loading software, DVD etc.
    When I first got the machine the DVD drive was operating just fine, however after trying to load Pinnacle TV tuner and SimCity4 it has stopped working and no longer shows in my computer.
    Any help would be appreciated

  • My external Firewire drive keeps coming up as read only after reboot.

    Hello everyone,
    I have a perplexing problem that just cropped up yesterday. I have an iMac (9,1) running Mac OS X 10.6.7. I've had the machine about a month now. I have an external 500GB Firewire 800 drive that holds all my iTunes music files. This was previously an internal drive in my G4MDD that I installed in an external exclosure I got from OWC. It's an EZ QUEST enclosure with an Oxford chipset. The drive is formatted Journaled HFS+, and I had reformatted it and copied all my files back over using Carbon Copy Cloner when I installed it in the enclosure. The drive is set in the Get Info window to "ignore ownership on this volume", and I have read/write permissions on the drive and the enclosing folders, including the iTunes folder. I can read the files, just not write to any directory on the drive.
    Everything had been working as expected until yesterday when I started up the Mac and went to download a Podcast. The Mac informed me that it couldn't download the file because I didn't have write permissions.  I checked the drive in the Get Info window, and everything was set correctly, but I noticed that I couldn't change the ownership options, as they were grayed out.
    I fixed the problem by running DiskWarrior 4.2 on it, and rebuilt the directory. After that the drive was fine; until I started up today and was faced with the same situation. I was able to fix it again in the same manner, but would like to get to the bottom of the problem. A few other bits, the drive was recently defragmented with Drive Genius 3.1, and both that and DW and Disk Utility say the volume is OK.
    I've been using Macs professionally and at home since '93 and this is my 5th Mac since that time. So I know my way around them, and I'm stumped!
    Any ideas?

    Oh, as part of this, not sure when the change was made, OSX used to keep the mounted volume name in /Volumes, even if the volume was ejected.  Would cause an occasional problem - but very rare.  I notice now that ML seems to create/delete these mountpoints automagically - and that's part of the problem.  They get incorrect permissions when the volume mounts, and I (user I'm logged in as), can't write to the volume without some background shenanigans.
    My process is this:
    Unmount problem volume
    Drop to terminal, and "sudo mkdir /Volumes/<mounted_volume_name>"
    Remount volume via Disk Utility (you now get a "<mounted_volume_name> 1" - with CORRECT permissions)
    Unmount the volume again
    Remove the created directory (i.e. undo step 2)
    Remount the volume - 99.9% of the time that seems to fix it.
    Reboot to be sure - and it stays for a while - then at some point becomes a problem again.
    Not sure if it's something in ML that's an issue - or something in iTunes or iPhoto (but can't see how they would affect the permissions when the system reboots and you login)

  • Dv2915nr cd/dvd drive doesn't recognize when disk in. drive doesnt show up in device manager.

    dv2915nr cd/dvd drive doesn't recognize when disk in. drive doesnt show up in device manager.

    Hi,
    Here's one option you could try as it will give a good indication whether the problem is with Windows or a Hardware issue with the optical drive itself. 
    Create a bootable Ubuntu CD
    The Ubuntu CD you create should run as you boot the notebook ( ie outside of Windows operating system ), so if this will not run, the problem is almost certainly a Hardware issue with the DVD drive
    On another PC, follow the procedure on the link below to create a bootable Ubuntu CD and follow the steps in Part 3 to 'Try it' to see if this OS will run from the CD.  The 'try it' option does not need to install on the Hard Drive, it just runs from the CD.
    http://www.ubuntu.com/desktop/get-ubuntu/download
    Let me know if this will run.

  • A205-S7464 DVD Drive doesnt read cds!

    I have a A205-S7464 Laptop. running windows vista home edition sp1. my dvd drive doesnt read any cds! i dont know whats wrong. Could it be a driver issue? does it need to be updated or is the drive defective all together? the drive shows up in windows explorer and in the hardware devices it says its working properly! the drive is HD TS-L802A ATA. Driver 6/21/2006 ver. 6.0.6001.18000.
    I just restored my system with the recovery disc. it read that fine. then i updated to vista sp1. didnt check if it read any cds before the update but doesnt read any cds now.... i think its a software issue the drive tries to read the cd but never actually reads it....

    Hi-
    Try downloading and installing the Patchburn Utility. It might help your media reading. I assume this is a disk that someone burned? Could be your drive doesn't like the media, itself, or the burn speed was too high for your 5x DVD=ROM to read.
    If Patchburn doesn't help, may be time to move up to a more modern drive to replace your antique.....
    There is a real nice,Pioneer DVR-112 replacement you might consider.

  • My DVD drive doesnt work

    My dvd drive doesnt work, and i want to format the HD, any ideas??? i have an external dvd drive but it doesnt recognice it when i want to install the OS,
    ... Maybe someone can tell me how. Thanks

    Time to take your disc and your computer to an Apple Store or an AASP, I'm afraid. They should be able to reinstall the OS, etc. Have no idea what they would charge but I'm sure that it would not be too expensive.

  • DVD drive not showing...

    Hi, first off, thanks for reading this, I hope you'll be able to help me out. My DVD drive doesn't show up on my HP Pavillion dv2000 anymore. It doesn't even show up in the hardware manager.
    I tried the upper filters/lower filters fix, but I don't see any registry entries with those names in the registry folder that is  specified across many threads/FAQs. There is however, one folder called: "properties", but I'm denied access to it, even though I'm administrator. I also tried an autofix program linked in another thread (the file was called: XP_CD-DVD-Fix.zip) just to be sure.
    I've tried looking for driver updates on the HP site, but all they do is tell me to install HP support assistant for windows 7. I have windows Vista, so that's a problem. Any way I can download the driver without support assistant?

    Hi,
    The driver for any CD/DVD Drive is provided by windows.  Try the following.
    From the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'.  In to the prompt type the following command and hit enter.
    sfc /scannow                 ( note that there is a space between sfc and the / )
    Let the process complete, then type exit and hit enter.  Restart the PC.
    Next, from the Start Menu, open the Control Panel and click on Device Manager.  Click to open the IDE ATA/ATAPI Controllers.  Right click on the first channel and select uninstall.  Do not delete drivers if asked.  When uninstalled repeat the process for each channel.  Also if an ATA controller is listed, right click and uninstall this, again not deleting drivers if asked.  When complete, see if the CD/DVD Drive now shows up in Device Manager.

  • Satellite A40-151 DVD drive will not play DVDs

    hi my dvd drive will play music cd's but when i try to play a dvd it just makes a beep and nothing happens i tried windvd and it comes on but everything is blurred and still wont play a dvd

    Hello John
    Please dont be mad on me but in your posting there is no question or something just small report that DVD drive will not play DVDs.
    Anyway, if I am remembering well your unit is about 2 years old and has probably DVD-CDRW (Combo) drive. In my opinion there is no much to do. If the drive has problem with original DVDs I presume that there is laser calibrations problem and the device must be replaced.
    I dont know how old is your unit exactly but please check if the warranty is still valid. If yes contact service partner in your country immediately. The drive should be replaced for free. If not you must replaced it on your own. If the drive replacement costs too much I recommend you to use external device (I do it with my old Satellite). On this way I can use newest and very fast super multi DL devices and also create own DVDs.
    You can also try to find already used DVD/CD-RW drive and replace it alone. If you need assistance by replacement please write again.
    Once again, dont be mad on me. I am ready to write my opinion but it is really annoying when someone write just one sentence and nothing more.
    Good luck!

  • Using DVD Player, the show goes back to menu after every chapter, even though I selected "Play Entire Episode".

    It only does this on Reading Rainbow DVDs so far: Using DVD Player, the show goes back to menu after every chapter, even though I selected "Play Entire Episode".  It does this whether the laptop is plugged in or is using battery power.  How do I get it to play all??  Thanks.

    Turns out it was NOT the software or the Mac. I bought a portable DVD player and this problem happens with it, too.

  • After BIOS update DVD driver do not read DVDs anymore - Sat A80

    Hi,
    I have a Satellite A80-131 and after bios update (last version 2.5) by windows procedure update, my DVD drive do not read DVD medias anymore. It is possible to read CD medias, but not DVD one.
    Can I reinstall the old bios? Can I reinstall the firmware?
    Thanks
    Ronai Lisboa

    Hi Ronai
    Like Jimi has said in the posting above. It's very unusual that after BIOS updating the DVD drive hasn't read the DVDs.
    Furthermore it's not advisable to use any 3rd party applications to DOWNGRADE the BIOS. Usually only the ASP can downgrade the BIOS. Such procedures are very serious and the wrong procedure can damage the motherboard.
    However, it's nice that you have solved the problem and that the drive works properly.
    Thanks for the feedback.

  • QT file burnt onto DVD doesn't show when DVD reinserted into drive

    This has happened several times now, and is beginning to affect my work.
    Here's what happens: I create a self-contained QT file from FCP (7.0.2, fwiw). I insert a blank single-sided (ie 4.7GB) DVD into my internal DVD drive, drag the QT file into it and click 'burn'. The burning process proceeds exactly as I would expect and, at the end, I can click on the DVD icon and see my QT file on the disc. I can open the QT file and play it.
    In fact, things don't go wrong until I eject the disc. When I've done that and I re-insert it into the same drive, suddenly the disc is blank! This happens even if I reboot the Mac Pro in the meantime. However, if I insert the drive into my partner's iMac, the QT file is there and can be opened. If I reboot my Mac Pro in Windows, the disc still shows up as blank - as it does on other people's PCs (haven't checked any other Macs yet).
    What can be causing this? The drive works fine in all other respects (eg playing movies, installing software, etc.). This problem started happening a few months ago, but in all other respects the drive is working fine. (Oh, I can successfully make a movie DVD from DVD Studio Pro, btw - it's just burning QT files that causes the problem.)
    Thanks in advance for your help, everyone.

    Well, I seem to have flummoxed you all. Problem still recurring, by the way.
    (Incidentally, when I said in my post "suddenly the disc is blank", I hope it was clear that the disc isn't actually blank - just for some reason my Mac thinks it is.)

  • HELP! DVD Drive not showing on finder or desktop

    Hi, I am not a Mc OS expert. I have a Mac Pro 1,1 with MAC OSX 10.7.5, and my original DVD drive died. I happened to have an HP Lightscribe DVD640, and I installed it, but, its icon does not show up!
    It is recognized by the system and Disk Utility, and if I insert a CD or DVD it reads it correctly, but when I remove it, there's no icon of the actual drive anywhere, so, I won't be able to open the drive to insert a new disc...
    I set the Finder preferences to show CDs and DVDs, but nothing shows...
    Any suggestion?

    but... this is a Mac Pro, it does not have a slot-in, how do I even open the drive? I was able to see the DVD drive icon before, and select "OPEN" and the tray would open, now, I don't se anything.

  • DVD drive doesnt read DVD-R discs on Mac G4/350 AGP?

    Hi,
    I noticed that my DVD-ROM drive can read a DVD+R and CD-R disc just fine, but when I stick in a DVD-R disc, it just ejects it. I'm using Mac OS X 10.4.
    Is this normal that the DVD-ROM drive can only read in DVD+R discs? The Apple Spec page doesnt say much about this.

  • [P67-A] DVD Drive not showing up?

    Hi all,
    I have a P67A i5 board and I'm baffled as to why the DVD drive isn't detected. It has worked in the past but doesn't now.
    I have 2 SATA HDD's connected to port 1 & 2 (the 6Gb/s ports) and I have a SATA DVD drive connected to port 8 but it doesn't show in the BIOS at all? I even purchased a new DVD drive to try and rule out the old one had failed but it still doesn't work. I am running in IDE mode but then that has always been the case.
    Does anyone know what could be the problem??

    Did your test your drive(s) on a different SATA-Port? 
    Does it show up in Windows?
    Does it show up in the UEFI/BIOS Boot menu (press F11 after start-up to bring up the boot menu)?
    Have you tried a different SATA cable?
