FIX: A disk read error occurred. Press Ctrl+Alt+Del to restart

Recently I suffered from a total system breakdown. Windows suddenly decided to stop booting, I didn't believe the cause of the error was bad hardware (faulty HDD) - the laptop is new.

I struggeled to find a solution, tried many things with the Windows installation disks. None of the automatic repair tools helped (system restore, automatic startup repair, boot-repair-disk).

It seemed the cause of the error was a broken MBR, caused by a process with access to system files, but boot-repair-disk didn't fix it.

After some more googling I found out that the Windows installation disk has another MBR fix tool, accessable from the command prompt.

Boot the system from the Windows installation DVD, then open up command prompt either with Shift+10 or by choosing it from the menu.

Then type:

bootsect.exe /nt60 C:

Windows 7 SSD Tips

The list may be updated.

• You probably already know this:
  Install large programs on the HDD instead of the SSD drive.
  
• Disabling hibernation saves you X GBs on the SSD drive, where X is the size of your RAM.
  Run cmd as administrator.
  Type in:  powercfg -h off
  
• Move Documents, Movies, Pictures, Music folder on the HDD drive.
  Moving these directories is easy. Just right-click on them, click Properties, click Location and click Move.
  
• Move AppData folder - this is the folder where your installed programs store temporary and/or your local data which is used by those programs. It can grow really large in size.
  There is no simple procedure to do this, so this option is not really preferred.
  
• Move the whole Users folder.
  LifeHacker has an article about it. Again, not a really simple solution.

Windows 7 File permission problem after reinstallation

Run command line as administrator

For Folders or Directories (will perform action recursively):

takeown /f directory_name /r /d y
icacls directory_name /grant administrators:F /t

Replace file_name or directory_name with actual file name or folder name, with path when applicable. The first command will take ownership of the file or folder specified, and the second command will grant full control permissions to administrators user group. Note that when using command for folders, to command will run recursively. To prevent the task been perform recursively, remove the “/r” and “/t” switch.

SiOL TV, dve mrežni kartici, VLC player, Windows 7 x64-bit

V primeru da vam IPTv ne deluje, če imate dve mrežni kartici (eno za internet in drugo za TV), poskusite pri mrežnem adapterju za TV nastaviti metriko na 2.



Ne pozabite na ostale nastavitve za vzpostavitev TV na VLC playerju:
-odprite VLC in pritisnite CTRL+P (Preferences)
-spodaj levo obkljukate Show settings "All"-s tem se omogočijo napredne nastavitve
-v meniju gremo na Input/Codecs - na desni pri UDP portu vnesemo pravi port, ki je za t2 "5000", pri MTU pa imam "1492", potem pa še obkljukamo "Force IPv4"
-gremo v meni "Video" in nato kliknemo "output modules" - pri "Video output modules" izberemo možnost iz seznama "OpenGL video output"
-nato v levem meniju izberemo meni "Stream output" in nato "Access output"
-V Access output sem v okence kjer piše "Multicast output interface" vpisal IP mrežne kartice, ki jo uporabljam za internet, v okence "IPv4 multicast output interface adress" pa sem vpisal IP mrežne kartice, ki jo uporabljam zgolj za IPTV
-zadevo shranite in ponovno zaženite program.

Windows 7/Vista & ArcGIS & ESRI License Manager

It seems that ESRI License Manager has difficulties running in Windows 7 or Vista – the License server fails to start at boot or on demand in License Manager Tools.
Consequently, ArcGIS didn’t start because there was no license server running. Obviously this problem doesn’t occur if the license server is running on another machine in the network.
At first I tried the quick and dirty solution – to manually start the server daemon and see where it fails.
I ran Command Prompt as an administrator:

Now, the server is called lmgrd.exe, so if you navigate to C:\Program Files\ESRI\License\arcgis9x and start lmgrd, it says that there is no license specified.
So I typed the location of the license (it was in the same folder), ran the program in the foreground:
lmgrd –c license.lic -z
I kept the command prompt open, and ArcGIS started succesfully.
But this isn’t really a long term solution, since this method would require manual server start in the command prompt everytime I would want to start ArcGIS.
So I thought, maybe the problem is that the server can’t find the license file. After some googling, I found out that the environment variable LM_LICENSE_FILE wasn’t set. It says on the support page that you’d need to enter port@machine-name for the variable value, but since we’re running the server on the local machine, you just need to enter your C:\Path\to\your\license.lic.

When all goes well with License Manager Tools, you might still need to enter "localhost" in the ArcGIS desktop manager in the license server.
If anyone has a better solution or information, please post in the comments.
UPDATE:
After further experimentation I found out that you also need the Sentinel driver to successfuly run License Manager on Windows 7. Don't know why, but it works. You should install Sentinel driver first, then the license manager, so that everything for the license works before you install ArcGIS. That way you won't have to manually configure ArcGIS for license after it has been installed. You have less work that way.
