Using DiskPart to format ReFS Print
November 2021
Create a new partition in the free space on the disk using diskpart. Select the newly created volume, and use the filesystems command within diskpart to see if ReFS is an available option for the new volume.

DISKPART> list disk
DISKPART> select disk x
DISKPART> create partition primary
DISKPART> filesystems

If ReFS is an available option:
DISKPART> format fs=refs quick
DISKPART> assign letter=x
 
Hyper-V Server Driver Install / Update Print
November 2021

Hyper-V-Server (as with Windows Server Core) does not give you access to the GUI and that means that you cannot access Device Manager to manage and update device drivers. Instead device driver management has to be done via the command line.

These are my notes on how to accomplish driver management tasks from the command line:

List device drivers

To list device drivers enter the following at the command prompt:

pnputil /e

Note: nothing will be listed if you have not manually installed any drivers from the C:\Compucon\Drivers folder yet.  Please go through each driver folder and install them manually. 

Update a device driver

The first task is to obtain the device driver (or updated device driver). Sadly there is no automatic way of doing this. So you will need to track down the device driver to use, visiting manufacturers websites is often a good place to start.

Once you have the device driver (unzipped if it is contained in a .zip file), use the following to install the device driver:

pnputil -i -a driver-inf

where driver-inf is the name of the .inf file for the driver, or to install all drivers in a folder:

pnputil -i -a *.inf

Update: check the C:\Compucon\Drivers folder for existing drivers in our OPK system

Enable and disable a device driver

Sadly there doesn't seem to be a way of enabling or disabling devices from the command line.

The best (free) tool I have found for listing, enabling and disabling devices is DevManView which is available here: www.nirsoft.net/utils/device_manager_view.html

Diskpart

Here are some commands for using DISKPART in the Terminal.

  • help
  • list disk
  • list vol
  • list part
  • sel disk x  (where x is a disk number listed under 'list disk')
  • sel vol x
  • sel part x
  • create part primary
  • help format (or format help)
  • assign (assigns a drive letter to the partition once it has been formatted)
  • exit

Horn Speaker Scares off Intruders (2021) Print
September 2021

Wireless Reference Sites 2020

 

 

  • One of the Compucon sites in Auckland CBD suffered a major fault of its carpark entrance gate which was near the end of its useful life. The gate could not open or close properly and it had to be replaced by a new one. The replacement procedure took about 2 weeks to complete. In the meantime, the carpark had no gate to protect cars inside. The area has a large number of street kids and zombies. Without a gate, the building owners and tenants felt very vulnerable.
  •  
  • Compucon was called up for emergency help. Compucon took 5 calendar days, including Saturday and Sunday, to do the system design and install cameras to monitor the gate and various locations inside the carpark. Most impressive of all, Compucon installed a horn speaker at the gate to scare off zombie intruders at night. The speaker is triggered by the camera detecting motions close to the camera (which could be zombies) and plays back a pre-recorded script. A provision has been made to send an alert email message to the building manager at the same time if he wants. The building manager can speak to the zombies remotely from his mobile phone. 
  •  
  • The clients were very thankful to Compucon of the fast actions taken to give a certain level of protection to the building.
