Replace Dell PERC H310 to H710 Raid Controller without losing data

Download PDF

I have successfully upgraded Dell PERC H310 Raid Controller with H710 without losing any data. The process was very simple, pretty much plug and play. Before the upgrade I tried to consult with the Dell techs, but they had no idea about the process and its outcome since apparently no one ever had a need to do it, but me. Well, i guess I am a pioneer now 🙂

To assure everyone it really works, I took a video, watch bellow.

Any questions feel free to ask.

1. Remove the old PERC H310 card

2. Insert new PERC H710 (make sure to plug in the SAS connectors)

A required privilege is not held by the client when you try to create a file or folder on the c drive of Windows 8.

Do not turn UAC off from Windows 8 control panel.

Instead, go to registry and do the following:

  1. Press keys “Windows Key + R”, type regedit
  2. Locate HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System\EnableLUA
  3. Update the EnableLUA value to 0 (turn if off)

Tested, works 🙂

Yet again, thanks Microsoft for a great OS!

How to fix: Hotmail & Gmail mark me as SPAM – Be careful! This sender failed our fraud detection checks.

Download PDF

If your emails keep going to people’s “Junk” or “Spam” folders on either GMAIL or HOTMAIL this is how to fix it:

GMAIL, HOTMAIL and many other public email systems use Sender Policy Framework (SPF) to recognize legit senders.

If you do not have a valid SPF Record in place, your emails won’t pass the security check and will me marked as SPAM.


1. You need to access your Hosting Control Panel, where the domain in question is hosted. In our case we use cPanel.


2. Find DNS Zone Editor icon (either Simple or Advanced)


3. Chose the domain you want to add the records to and add the following details



v=spf1 ip4:ipaddress/24 -all

v=spf1 a mx ~all

v=spf1 +a +mx +ip4:ipaddress ?all


First option is to use the public ip address /24 in that subnet

Second option uses the server FQDN no matter what the IP is

Third option uses the public ip address regardles of subnets


Second option us usually the most correct option since it uses a FQDN regardles of it’s public IP address..


Hope this helps 🙂

If any questions feel free to comment or private message me.

By Microsoft, works great.
