How to Fix: Attach, Rebuild RAID 5 after Failed Disk (Dell PERC S100, S300)

Infopackets Reader Harlen W. writes: " Dear Dennis, I own a Dell PowerEdge T110 server, which runs Windows Server 2008 R2 Foundation and is equipped with a Dell Perc 300 RAID card . We have 3 x 250 GB hard drives in RAID 5 format attached to the ... Perc 300 RAID card. According to the Dell OpenManage Server Administrator (which we use to manage the RAID via the browser), the 'Alert' log file is reporting ' Device failed: Physical Disk 0:1 Controller 0, Connector 0 '. I would like to hire you to help me fix this problem, including testing the failed hard drive . If it passes, I want to put it ... (view more)

How to Fix: Test RAID for Bad Sectors (Sync Errors)

Infopackets Reader Steve H. writes: " Dear Dennis, I have a RAID 1 set up with 4 hard drives in a mirrored array. Recently my RAID software reported that one of the drives was dropped from the array and has since been marked as 'rebuilding', ... however, during the rebuild process I keep receiving RAID controller errors that data could not be synced / written to the drive. I'm not sure what to do from here. Is there any way for me to independently check the drive for errors? I understand that if the drive is bad I should replace it, but I'm not even sure which drive is which. " My response: This ... (view more)

Is the Truth Really Out There? We May Soon Find Out

Is the truth really out there? Or, is it just a bunch of wiener aliens? Regardless, X-Files fans (and just about anyone else) will be interested in a recently launched California project, which actively searches outer space for signs of ... intelligence. The search, led by astronomer Dr. J. R. Forster, officially began on Thursday with the activation of a radio telescope array. The project, funded by the University of California, Berkeley, is now probing the universe with 42 individual radio dishes collectively referred to as the Allen Telescope Array (ATA). Eventually, Forster and his team hope ... (view more)

Using 4 hard drives in RAID-0 configuration?

This article is a bit technical and relies on know-how from a previous article I've written about RAID. In brief, the word 'RAID' is a techy-term which stands for Redundant Array of Independent (or Inexpensive) Disks. A hard disk array is simply a ... bunch of hard drives chained together. Benefits of using RAID are generally two-fold, and include: increased file read / write performance (known as RAID-0), and data redundancy for backup purposes (known as RAID-1). I've previously written an article about RAID if you would like to read up on it . It is very simplistic and explains RAID essentials ... (view more)

RAID = Blazing fast Hard Drive performance

Have you ever had a RAID before? RAID is a technology used to increase hard drive performance and fault-tolerance. What is fault-tolerance? The hard drive inside your computer is responsible for storing programs and user data. RAID performance ... refers to the time that it takes the hard drive to read and write information; fault-tolerance deals with the means to protect data stored on the hard drive. RAID is an acronym which stands for Redundant Arrays of Inexpensive (or Independent) Disks. Generally speaking, the word 'Array' is a techy-term which represents related information formed in a ... (view more)
