About
**Context:** Windows nature connection of EOS-wnc to Windows operating system.
**Objectives**: The connection of the EOS-wnc on Windows platform should be as it is for Windows local disks, external disk storages, it means as a Windows disk driver letter.
**Method**: A storage on Windows operating is presented as a "disk drive letter". Architecture of Windows storage drivers has following layers as follows:
1. IRP for Upper-filter driver 2. IRP for Storage-class driver 3. SRB for Lower-filter driver 4. SRB for Storage port driver 5. SRB for Bus-specific commands
where *IRP (I/O request packets)*: kernel mode structures that are used by Windows Driver Model (WDM) *SRB (SCSI Request Block)*: SCSI command descriptor blocks (CDBs)
For EOS-wnc is implemented "thin" Windows disk driver.
**Result**: Windows driver software is low-level software and bugs in low-level software can be extremely painful; bugs can cause a loose of all data on disk drive including operating system. Therefore, the EOS-wnc Windows drivers implementation is a "thin driver" to maximize stability and security of this part of software..
