32 byte CDB support for SCSI_PASSTHROUGH RRS feed

  • Question

  • Hi everyone,

    I have a question about support for 32-byte CDBs in Windows.  I have need to use 32-byte CDBs through the SCSI_PASSTHROUGH_DIRECT structure and associated IOCTLs.  It seems that this support is available in Windows 8 and beyond.  Though, one discussion I came across seems to hint that if we define our own structure, with a 32-byte length CDB field, we could accomplish this.  Another thread I found seemed to indicate that we'd have to develop a custom driver (it mentions implementing a new IOCTL with takes a 32 byte CDB).  I'd like to confirm.  Here are relevant links to the information I've found:

    Thanks for any insight.
