• Portege A600-133: DVD player disappears from my computer

  Hello

  I have a laptop Portege A600-133.
  First of all, it is slow at the opening of my computer screen.

  Second: after ejecting a disc dvd or cd, Windows still shows the contents of the disc, the system hangs for a while, a USB unplug sound can be heard and the dvd player disappears from Windows (in my computer / Explorer / Device Manager)

  What this may be?

  I did already the round of upper/lower filters in the registry, but it does not solve the problem...
  I opened the computer laptop and checked the wiring to the dvd drive, cleaned the contacts, supported on the connectors.

  But the problem is still there...

  Hello

  My first idea was to remove the upper and lower registry key filters, but it seems that you have already done this.

  Nevertheless, here is a knowledge of MS on the upper and lower filters article mentioned.

  You should also check if it of possible to boot from the bootable CD.

A window appeared in windows media player, saying that I had to install a burner/player. The ICON for the drive disappeared from my office. I can't find anything anywhere. I had just finished burning files to a CD - R disc in the 'Master Disc' configuration, with success. Dell support site is down at the moment.

• DVD ROM disappeared from the computer and VISTA Device Manager

  Hello

  I know there are a lot of discussions on the same topic, but I read everything and still my problem persists.

  I'm pretty sure that the problem occurred after installing iTunes. The DVD ROM is no longer accessible on my laptop. The light flashes and the attempts to start a disk, but then nothing.

  I was in the high register looking for filters and bass to remove (such as published in the number of threads). I found only UpperFilters which I deleted but still nothing. I also tried Microsoft FixIt but does not have the ROM either.

  What to do next? Can anyone help? He began to depress me now.

  Well, I have solved my problem. After trying everything I read and was advised to try.

  I simply unplugged the laptop and handed. Then, I reviewed the reader noticing only so slightly, I could see the silver housing of the reader. So I applied a bit of pressure, pushing the player to the laptop so that I could see is no longer the silver case.

  I have not for a minute think that might be the problem. Once the laptop is started, Windows immediately installed the driver and open computer it was. DVD ROM restored.

  Not sure if this may help someone of you guys, but if I post my "fix" :-)

• HP Photosmart D5460: printing of DVD disc disappeared from Photosmart Essential.

  Did not burn any DVD for a while, so when I pulled upward Photosmart Essentials 3.5 for print direcrtly the disk, the model had disappeared.

  I'm sure it was the Create topic when I used it last until I upgraded to Windows 10, I have art work I designed saved on my drive but also I downloaded on the web.

  Where is he gone please?

  Hi @NorskYorkie,

  Glad to see that you are using the HP forums, this is a great question other customers might wonder about too!

  Although there are software to the new version of the operating system such as Windows 8 and Windows, CD/DVD, print front 10 has been omitted in the software, I think that this feature has been deprecated. You might be able to find a 3rd party screen software that allows you to print on CD/DVDs that you can download and use. I suggest using Google to see what is available. If you can't find anything, you can consider using this printer with an older operating system.

  I'm sure that's not the answer you were hoping for, but if that answers your request, please consider tagging this post as solved by clicking accepted as Solution below and others can find the answer more effectively.

  Note: the data files that are infected must be cleaned only by removing the file completely, which means there is a risk of data loss.

• Driver DVD disappear from 'My computer' and 'Device Manager '.

  Vista HP Portable DVD player continues to disappear from 'My computer' and 'Device Manager '. Already tried Upper/LowerFilters.

  Hi, a few weeks ago, the DVD burner in the laptop suddenly disappearedmy computer (Windows Explorer).  The first thing I did was check theDevice Manager to see if the drive was there.  It was not the case.  Restarting the laptop did nothing.  Repeated several times, active Vista updates.  No change.  By checking the net, I tried to delete the Upper/LowerFilters in the registry, download it tool Microsoft fix , delete iTunes, do a system restore, to change all the parameters of thesleep and hibernation off and a few other things.  It appeared for the first time after that:

  1. Do a restore of the system for the first restore point.
  2. Remove the DVD writer.
  3. Restarting the laptop.
  4. Research of new hardware in Device Manager .
  5. Change all parameters of standby and Hibernate off. (I tried this method without this step first, but the drive disappeared after the computer went to sleep and woke up.)  Tried 3 times with the same results).
  6. Closing.
  7. Reinsert the DVD burner.

  On the next reboot, the DVD writer has been recognized and ended up in my computer and Device Manager .  No errors of any kind and no drivers were installed at startup.

  What has happened since then, in the last 4 or 5 days, is randomly disappears from thedesktop .  Usually after a few hours or more.  This time, however, it usually appears inDevice Manager after a search of new material.  No reboot required.  It will read from a DVD .avi files each time.  It has not been detected byDevice Manager maybe about 2 or 3 times, and after a simple reboot, it will be present inmy computer and Device Manager automatically after a reboot.  I read that the superior/UpperFilter mark has worked for many people, but for some, the problem returns.  In addition, many of the discussions on this question and proofreading are years.  It happened about 10 days ago.  Within 2 days before the problem appeared first, it was an update of windows, but also an update of iTunes.

  I noticed that I received this error when opening iTunes:

  "The registry settings used by the iTunes for importing and burning CDs and DVDs are missing. This can occur as a result of installing other CD burning software. Please reinstall iTunes. ''

  I have not reinstalled, no DVD player.  Uninstalled itunes again.  Since I finally got the drive to appear (using the method I described above), I did bother to reinstall iTunes because I particularly need it on this computer, worried that it may be the cause of the original problem and I wanted to see if the disc disappears again.  I did do it, however, let QuickTime installed.  Don't know if this could be a problem?

  I stumbled upon this suggestion, but I also had the same question as the next post, and I have not seen a response.  I don't know if or how I should try:

  Nikki,

  You can not go back if the restore points aren't there. Try to reinstall the IDE driver.

  To do:
  -Click on the round to start and right click on computer
  -Left click on properties, this will open the system window
  -Click on device high Managerin left
  -Click on continue if prompted by UAC
  -Goto the 'IDE ATA/ATAPI controllers' you should right click on uninstall and restart

  BTW that dog rox in this avitar

  See you soon! MCP. MCDST. LVL 80

  Hi, thanks for the comment on my puppy. She is now 5 MB and her name is Nikki, lol.

  Well, I tried what you said, but the IDE ATA/ATAP controllers has a (+), so when I select it does give me not an option to uninstall. It is for me (analysis of the physical changes (or) properties).       and if I click on the (+) sign I have 4 different options. 2 channels IDE, Intel (R) 82801 HEM / HBM SATA AHCI controller and Intel(r) ICH8M Ultra ATA Storage controllers - 2850.

  http://social.answers.Microsoft.com/forums/en-us/vistahardware/thread/e3701d75-9dbe-4ae9-9d70-83f14129247c?Prof=required

  What I see in "Device Manager", under IDE ATA/ATAP controllers is:

  IDE channel (x 4)

  Ricoh Memory Stick Controller

  Ricoh SD/MMC Host Controller

  Ricoh xD-Picture Card Controller

  Controller of PCI standard IDE dual channel (x 2)

  The laptop is about 2 years and never had problems.  The DVD burner is hardly used to burn, maybe a total of 5 disks in this time.  It has been used occasionally to read or copy from, but not much.  I'm not convinced that he is dead, as I had 2 die on me in desktop computers, after burning hundreds of CDs in them and read much.

  in any case, I was not able to find any bugs or suggestions (with the exception of 'replace' the reader), so I just wanted to describe my specific situation and see if anyone could help out.  Forgive me for information, I have left out, but I am an amateur when it comes to the problems with the computer and still don't know what mean things or where I can get information on my OS, software or hardware.  All anyone can do would be greatly appreciated.

  This is the information I have:

  HP Pavilion dv6700 Notebook PC

  Optiarc DVD RW AD-7560 ATA Device

  Vista Home Premium

  Service Pack 2

  Thanks again for any help.

• DVD RW drive disappears from the computer and the Device Manager on Windows 7 ultimate 32 bit

  After upgrading Vista to Windows 7, my DVD RW drive will disappear from official view and computing device and a scan for changes on the material or use of the player will not solve. Resolves a reboot of the PC (HP - Sony DVD RW desktop computer).
  It appears in the BIOS and when the first install Windows 7 found and the device manager reported everything is ok. It seems that after a power management feature has occurred and the PC wake up the disc is missing and the only way to return it is a restart.
  Help, please

  Thanks for the info, I had seen it work elsewhere on the net for similar problems with Vista, but not of joy as the either the upper or lower part reg entries appear under this subkey. They do it for the disk subkey but no CDROM

  Hibernation is disabled and I use power management to High Performance with only a screen sleep as a default 20 mintes and the hard drive after an hour of sleep. I upped since the two of them to see if that helps.
