CentOS Linux Parted Error: Unable to open /dev/sdc – unrecognised disk label

While rebuilding a large RAID 5 logical drive I had to use parted instead of fdisk. It has been awhile since I had to build a logical drive that was over 2TB so it had been quite awhile since I have used parted which will perform the same basic functions as fdisk and more. Anyhow when first attempting to use parted to create a partition table on the logical volume sitting on top of an Adaptec RAID card with multiple 2TB drives configured as RAID 5 on CentOS Linux I ran into an error. The resolution is easy but needed to note for myself as much as anything else.

Configure USB Flash Drive To Work With Xbox 360

Instead of having a hard drive on your Microsoft Xbox 360 you can instead use any USB hard drive. The limitation is the fact that you can only format 16GB of any USB drive to work with the Xbox 360 so unless you want multiple partitions on the USB drive I would actually just purchase a USB flash drive with a maximum of 16GB of usable space. To use the USB flash drive with your Xbox 360 you have to first format the drive which is explained in detail below.

One of the hair stylist from barber shop a couple doors down from our computer shop came in today with a problem on her Vivitar X029 digital camera she got for Christmas. The 2GB SD memory card she was using was not working properly in the camera and she also let me know that this was already a new SD card because he first SD card she used had the exact same problem. Below is information about the problem itself and the steps used to resolve the problem.

Create A New Logical Volume In A Logical Volume Group With Space On A Linux Server

As noted in a previous article I have been working on a couple new Linux servers with a minimal install of CentOS on them. The /var, /usr, and / directories each were configured with 2GB of space within a logical volume group that has 1TB of space available. I first expanded the /var and /usr directory from 2GB to 20GB and then expanded the root, or /, directory from 2GB to 30GB. Once all three of these directories were expanded I next needed to create a new logical volume group and a partition to hold PostgreSQL data. Use the information below to create a new logical volume, format it with the ext3 file system, mount it, and configure it to be mounted automatically upon the next boot of the server.
