  • Bad Hard Drive Slows Down Computer


    Here's a proven example of what a bad hard drive can do, it was technically functioning OK in a RAID array but the system became extremely low and the load become high and IOWAIT was even higher and I always thought it was a bad application.  The truth is that this failing 1TB Hitachi has slowly gotten worse and caused huge slowdowns, (eg. 100% load on Thunderbird waiting for e-mails to load etc..).  After swapping it out, tabs change instantly, emails are not lagged, and........

  • Centos 5 and OpenVZ won't boot after kernel install


    For whatever reason the current OpenVZ yum repo file enables the RHEL6 version of OpenVZ, why is this bad?  Because if you're running Centos 5 it still defaults to using the kernel from RHEL6 which won't work on RHEL5/Centos 5. I only realized this after wondering why I couldn't boot into OpenVZ that it was using one meant for RHEL6.

  • How To Test If Your Hard Drive Is Good/Signs of dying hard drive

    Let the numbers speak for themselves, from what I read the Load_Cycle_Count which is very high (more than 500,000/half a million times) is the number of head parks.  What a stupid "Green" design and design flaw which will probably mean an early life for the drive. This is almost as silly as Seagate's new reputation for BSY/poor quality disks since the 7200.11 series. To make it worse this is also when Western Digital introduced "Advanced Format" o........
  • XBOX 360 No Sound over HDMI Solution/Fix


    My XBOX's dashboard/firmware was from sometime in 2008 when I first bought the system.  I mainly played using composite cables but at my brother in law's house we used HDMI.  The very first time it worked, but then I bought some games that did some update and after that HDMI never worked. The symptoms besides having on sound is that your XBOX will show PC monitor resolutions but won't have any option to say you have a 720P or 1080P display, this means the XBOX firmware is fa........

Everyone knows that the firmware is flawed, even though I have the F6, it still seems that the system doesn't reset properly or quickly enough. Another HUGE problem is that in most Linux kernels the NIC won't work (if you try 10 times by rebooting it might).  I also notice that you need to power down for it to work.

    It always worked fine before but no amount of power unplugging/cycling does any good.  I can access one network share and that is one that I've already saved, but it can't see any workgroups. One silly thing is why is there no option to manually connect to a netbios name or IP? It seems there is a bug with the firmware and that the SMB client is not working properly.  Hopefully it fixes itself at some point. Between this and the lack of support for embedded s........

    NEC ND-3500A is great!I just picked up an NEC 3500A a few weeks ago and I love it. It is a great all in-one optical drive solution. It can burn DVD/+R-R at up 16x, read at 16x and rewrite at 4x and CD-R at up to 48x! Not bad, but the impotant part is that it delivers consistent high quality burns and the drive is as quiet as I could ask it to be. It's also convenient that it has a lot of hacked firmware for overspeeding of........
