- Quando sparisce il masterizzatore o ci sono problemi di questo genere di solito si risolve eliminando una o 2 chiavi di registro.
- Prima fai un bel backup del registro...si sa mai.
- Poi vai su HKEY_LOCAL_MACHINE-->SYSTEM-->Currentcontrolset-->Class-->4D36E965-E325-11CE-BFC1-08002BE10318 ed elimini le 2 voci Lowewr
- Filters e Upper Filters.
- In questo modo il masterizzatore non dovrebbe più darti problemi.
- Citazione:Following the installation of Windows 7 RTM some users may find that their DVD drives will be rendered inaccessible, even though
- the devices functioned under normal parameters before the deployment of the latest Windows client. Microsoft noted that it was aware of the
- issue, and provided a few workarounds for the affected customers to regain DVD drive functionality. According to the Redmond company
- symptoms involve completely or only intermittently inaccessible DVD drives post-Windows 7 installations. According to Microsoft, there is
- an issue with the firmware for some DVD drive products and the Adaptive Link Power Management (ALPM) in Windows 7.
- The software giant even revealed the specific devices that are affected by problems: “This problem may occur if you use one of the
- following DVD drives on the computer: Sony BC-5100S DVD, Sony BC-5600S DVD and TSST TS-L633B DVD+/-RW.”
- According to Microsoft there are two workarounds that end users can turn to. The first is the simplest, and it involves updating the
- firmware for Sony BC-5100S DVD, Sony BC-5600S DVD and TSST TS-L633B DVD+/-RW. “To check for an applicable firmware update, contact the
- manufacturor of the DVD drive,” Microsoft noted.
- At the same time, the Redmond company presents an alternative designed to let Windows 7 users regain DVD drive functionality in the
- eventuality that a firmware update is not available. The second mitigation involves disabling the Adaptive Link Power Management (ALPM)
- feature.
- “ALPM is a feature that puts a hardware device into sleep state after 100 ms of idle time. This is a power-saving feature. After you
- disable ALPM, you can still configure the drive to run in any one of three power plans: Performance, Balanced, and Power Saver. However,
- you cannot still benefit from the additional power saving that is provided by ALPM,” Microsoft explained.
- In order to disable ALPM users will need to first open a command prompt. Just enter cmd in the search box under the start menu and right
- click the selected result choosing Run as Administrator. There are a total of six commands that users must run, Microsoft revealed, all of
- them included below. Commands must be executed in this order:
