Run Check Disk from the Command Line to Find and Fix Errors

You can run Check Disk from the command line or within other utilities. At a command prompt, you can test the integrity of the L drive by typing the following command:

chkdsk L:

To find and repair errors that are found in the L drive, use the following command:

chkdsk /f L: 
Note that Check Disk can’t repair volumes that are in use. If the volume is in use, Check Disk displays a prompt that asks if you want to schedule the volume to be checked the next time you restart the system. Click Yes to schedule this.

The complete syntax for Check Disk is this:

chkdsk [volume[[path]filename]]] [/F] [/V] [/R] [/X] [/I] [/C] [/L[:size]] 

The options and switches for Check Disk are used as follows:
Volume Sets the volume to work with.
filename FAT/FAT32 only: Specifies files to check for fragmentation.
/F Fixes errors on the disk.
/V On FAT/FAT32, this displays the full path and name of every file on the disk. On NTFS, this displays cleanup messages, if any.
/R Locates bad sectors and recovers readable information (implies /F).
/L:size NTFS only. Changes the log file size.
/X Forces the volume to dismount first if necessary (implies /F).
/I NTFS only. Performs a minimum check of index entries.
/C NTFS only. Skips checking of cycles within the folder structure

How to Cable an EMC VNXe for Failover & VMWare

I really struggled with cabling a new VNXe for failover with vSphere. It's not difficult. There's just not a lot of documentation or explanation out there for it. The best practices docs and howtos treat iSCSI like a 3rd class citizen and assume you'd really rather be using Fiber or NFS. So here's how you really do it and a little explanation about why. We'll go into the details of the vSphere configuration after covering the hardware end of things.

PFSense – An Awesome Firewall

pfSense is an open source firewall/router distribution based on FreeBSD. pfSense is meant to be installed on a personal computer and is noted for its reliability and offering features often only found in expensive commercial firewalls. It can be configured and upgraded through a web-based interface, and requires no knowledge of the underlying FreeBSD system to manage. pfSense is commonly deployed as a Perimeter Firewall, router, wireless access point, DHCP server, DNS server, and as a VPN endpoint.

The name was derived from the fact that it helps make the OpenBSD packet-filtering tool pf make more sense to non-technical users.
