Linux Tip: Replacing GKSUDO for CENTOS users

January 20th, 2008 · No Comments · Linux

Hard Disk MTBF: Flap or Farce?

March 4th, 2007 · No Comments · General, Linux, SBS2K-SBS2K3

 
Data sheets for hard drives have always included a specification for reliability expressed in hours: commonly known as MTBF (mean time between failures), or sometimes the mean time to failure.
