Unmap command is failing on NTFS filesystem volume RRS feed

  • General discussion

  • Hi,

    I got following error while sending unmap to the volume having any windows file system.

    C:\Users\Administrator\Desktop\sg3_utils-1.35exe>sg_raw.exe PD1 42 00 00 00 00 0

    0 00 00 18 00 -i Unmap_data -s 24 -v

        cdb to send: 42 00 00 00 00 00 00 00 18 00

    Windows DeviceIoControl error=5

    >>> transport error: Access is denied.

    Same command is working fine if there is no file system present.

    Kindly let me know your valuable suggestions on this scenario.

    Regards,

    Sai
