Nedavno sam naišao na problem gdje je moj DVD pogon na Windowsima^(Windows) nedostajao na popisu uređaja u Mojem računalu^{(My Computer)} . Bilo je tu i ranije, ali jednostavno je nestalo! Nakon nekog istraživanja, pronašao sam nekoliko rješenja koja su uspjela.

Nažalost, rješenja se razlikuju ovisno o tome koji OS koristite: XP, Vista ili Windows 7/8/10 . Pokušat ću navesti što više rješenja za ovaj problem i koji OS se također primjenjuje.

Ponovno instalirajte upravljačke programe

Puno puta biste mogli vidjeti poruku poput ove u Upravitelju uređaja^{(Device Manager)} o vašem CD/DVD pogonu:

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Možete ponovno instalirati upravljačke programe za CD/DVD pogon tako da odete na Start , Upravljačka ploča^{(Control Panel)} , Sustav^(System) i sigurnost^(Security) , Sustav^(System) , a zatim kliknete na Upravitelj uređaja^{(Device Manager)} .

Expand CD/DVD-ROM Drives , zatim desnom tipkom miša kliknite uređaj i kliknite Deinstaliraj^(Uninstall) . Ponovno pokrenite računalo i Windows bi trebao automatski otkriti pogon i ponovno instalirati upravljačke programe umjesto vas.

Ako se vaš hardver čak i ne prikazuje u Upravitelju uređaja^{(Device Manager)} , možda zapravo imate hardverski problem, kao što je neispravna veza ili mrtvi disk. Ovu opciju vrijedi provjeriti ako je računalo staro.

Provjerite BIOS postavke

Ako ste nedavno bili u BIOS- u , trebali biste se pobrinuti da pogon nije slučajno onemogućen. To je inače vrlo rijetko, ali postoje prilike kada se može dogoditi. To je osobito istinito ako ste svoje računalo dali nekome na popravak ili nešto slično.

Trebali biste osigurati da se CD/DVD ROM pogon barem prikazuje kao opcija na stranici s opcijama pokretanja^(Boot) .

Problem gornjih/donjih filtera

Ako vaše Windows XP ili Windows Vista računalo ne može prepoznati CD/DVD pogon, možda imate klasični problem koji se vjerojatno neće pojaviti ni na jednom računalu na kojem su primijenjena najnovija ažuriranja sustava Windows .^(Windows)

Morate urediti dva unosa u registru da biste riješili problem u sustavima Windows XP^{(Windows XP)} i Vista . Možete to učiniti ručno ili možete preuzeti popravak s Microsofta^(Microsoft) ovdje:

http://support.microsoft.com/mats/cd_dvd_drive_problems/en-us

Ako to želite učiniti ručno, idite na regedit i idite na ovaj unos:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

U desnom oknu trebali biste vidjeti Gornje filtre^{(Upper Filters)} i Donje filtre^{( Lower Filters)} . Izbrišite^(Delete) oba ova i zatim ponovno pokrenite računalo.

Pokrenite alat za ^{(Run Hardware)}rješavanje problema^{(Troubleshooter)} s hardverom i uređajima^(Devices)

Ako imate problema u sustavu Windows 7^{(Windows 7)} , možete pokušati pokrenuti alat za rješavanje problema s ^{(Troubleshooter)}hardverom^(Hardware) i uređajima^(Devices) . To će automatski dijagnosticirati i pokušati riješiti problem.

Imajte na umu da će ovo vjerojatno funkcionirati samo ako možete vidjeti CD/DVD pogon u BIOS -u i Upravitelju uređaja^{(Device Manager)} , ali ne igdje drugdje u sustavu Windows^(Windows) . Ako ga ne vidite na ta dva mjesta, imate problem s hardverom ili vezom.

Alat za rješavanje problema možete pokrenuti tako da odete na Start , Upravljačka ploča^{(Control Panel)} i zatim potražite alat za rješavanje problema^{(troubleshooter)} u okviru za pretraživanje. Kliknite na Rješavanje problema^{(Troubleshooting)} . Konačno, u odjeljku Hardver^(Hardware) i zvuk^(Sound) kliknite Konfiguriraj uređaj^{(Configure a device)} .

Kliknite Dalje^{(Click Next)} i Windows će otkriti probleme i pokušati ih automatski popraviti.

Uredi Registry

Ako ništa od toga ne uspije, možete pokušati urediti ključ registra koji je možda izbrisan ili oštećen. Otvorite naredbeni redak administratora i kopirajte i zalijepite sljedeće:

reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001

Ponovno pokrenite računalo i provjerite je li disk sada prepoznat.

Drive Letter

Također biste trebali provjeriti ima li pogonu dodijeljeno slovo pogona i da to slovo nije već preuzeo drugi uređaj. Pročitajte moj prethodni post o tome kako promijeniti slova pogona u sustavu Windows^{(change drive letters in Windows)} da vidite uzrokuje li slovo pogona da se pogon sada prikazuje.

Vraćanje sustava

Ako i dalje imate problema, a vaš se pogon pojavljivao ranije, ali sada ga više nema, možete pokušati izvršiti vraćanje sustava na vrijeme kada je pogon ispravno radio.

Ponekad je instaliran novi softver koji može oštetiti vaš sustav tako da više ne prepoznaje vaš CD/DVD pogon.

Ako to ne uspije, pokušajte priključiti pogon na drugo računalo i provjerite prikazuje li se tamo. Brzo možete utvrditi radi li se o problemu s hardverom ili s operativnim sustavom Windows . Sretno!

CD/DVD Drive Missing in Windows?

I recently ran into a рroblem where my DVD drive on Windows was misѕing from the list of devices in My Computer. It was there earlier, but simply disappeared! After doing some research, I found a couple of solutions that worked.

Unfortunately, the solutions are different depending on which OS you are running: XP, Vista or Windows 7/8/10. I’ll try to list out as many fixes for this problem as I can and which OS it applies too.

Reinstall Drivers

A lot of times, you might see a message like this in Device Manager about your CD/DVD drive:

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

You can reinstall the drivers for the CD/DVD drive by going to Start, Control Panel, System and Security, System and then clicking on Device Manager.

Expand CD/DVD-ROM Drives, then right-click on the device and click Uninstall. Restart the computer and Windows should auto-detect the drive and reinstall the drivers for you.

If your hardware is not even showing up in the Device Manager, then you may actually have a hardware problem, such as a faulty connection or a dead drive. It’s worth checking this option out if the computer is old.

Check BIOS Settings

If you recently were in the BIOS, then you should make sure that the drive didn’t get disabled by accident. This is normally very rare, but there are occasions when it can happen. This is especially true if you gave your computer to someone else for a repair or something of that sort.

You should make sure that the CD/DVD ROM drive at least shows up as an option in the Boot options page.

Upper Filters/Lower Filters Problem

If your Windows XP or Windows Vista computer is not able to recognize the CD/DVD drive, then you might have a classic problem that will probably not show up on any computer that has the most recent Windows updates applied to it.

You have to edit two registry entries to fix the problem in Windows XP and Vista. You can either do it manually or you can download the fix from Microsoft here:

http://support.microsoft.com/mats/cd_dvd_drive_problems/en-us

If you want to do it manually, go to regedit and navigate to this entry:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E965-E325-11CE-BFC1-08002BE10318}

In the right pane, you should see Upper Filters and Lower Filters. Delete both of these and then restart the computer.

Run Hardware and Devices Troubleshooter

If you are having the issue on Windows 7, then you can try to run the Hardware and Devices Troubleshooter. This will automatically diagnose and try to remedy the problem.

Note that this will probably only work if you can see the CD/DVD drive in the BIOS and in Device Manager, but just not anywhere else in Windows. If you don’t see it in those two places, you got a hardware or connection problem.

You can run the troubleshooter by going to Start, Control Panel and then searching for troubleshooter in the search box. Click on Troubleshooting. Finally, under Hardware and Sound, click Configure a device.

Click Next and Windows will detect problems and try to fix them automatically.

Registry Edit

If none of that works, you can try editing a registry key that may have gotten deleted or corrupted. Open an administrator command prompt and copy and paste the following:

reg.exe add "HKLM\System\CurrentControlSet\Services\atapi\Controller0" /f /v EnumDevice1 /t REG_DWORD /d 0x00000001

Restart your computer and see if the drive is now recognized.

Drive Letter

You should also make sure the drive has a drive letter assigned to it and that the letter is not already taken by another device. Read my previous post on how to change drive letters in Windows to see if the drive letter is causing the drive now to show up.

System Restore

If you’re still having issues and your drive was showing up earlier, but now it’s gone, you can try to perform a system restore to a time when the drive was working properly.

Sometimes a new piece of software is installed that can corrupt your system so that it no longer recognizes your CD/DVD drive.

If that doesn’t work, try plugging the drive into another computer and see if it shows up there. You can quickly determine whether it’s a problem with the hardware or with the Windows operating system. Good luck!
