How to verify ReadyDrive is on? RRS feed

  • Question

  • I have made the appropriate GP Changes, but am still wondering if ReadyDrive is actually turned on.  How do I tell if it is?

    The Devie properties jsut tells me under the NV Cache tab that the system has 243 MB for use and can help improve performance. A Reboot was made after the Local Policy was enable, so why is it still saying this?

     

    Thanks

  • Hi David,

     

    As ReadyDrive is a feature included in Windows Vista Home Premium, it is enabled automatically if the H-HDD has passed the performance assessment. In other words, you needn’t use group policy to enable it manually.


    ReadyDrive is the software in Windows Vista that supports hybrid hard disk drives (H-HDD). An H-HDD is a traditional hard disk drive with integrated nonvolatile (NV) flash memory that acts as a high performance cache for writes and low-latency reads.
     

    You may use the following step to confirm whether it is active:
     

    1.   In Device Manager, expand the Disk drives node.

     

    2.   Right-click the flash disk item and select Properties.

     

    3.   You may check the feature in Policies tab.

     

    For the group policy object that can enable or disable NV cache, you may check it using the following steps:

     

    1.   Click Start icon, and then click Run…

     

    2.   Type gpedit.msc and press Enter. Click Continue if receiving UAC prompt.

     

    3.   You can find the group policy object in the path: Computer Configuration – Administrative Templates – System – Disk NV Cache.

  • Hi.

    I have seagate hhd and I cannot find Flash disk under disk drives in device manager. Does that mean nv cache is not enabled?

  • This answer is inappropriate.  Since the answer (as specified in it's first sentence) is for Windows Home Premium users,  it should not instruct the user to make use of a facility that does not exist and cannot be installed on Vista Home Premium, namely gpedit.msc

    It would be more appropriate to make available a read-only version of gpedit.msc
