How Long Will SD Cards Last?

November 27, 2006

Typically flash memory can be read and written 300–600 times. After that it will get unreliable. That being said, the user must be careful and cautious with the way flash memory cards are handled, where they are placed, what they are exposed to, etc. Just like RAM, be sure not to touch the gold bottoms of each card, as that will make it difficult for the cards to be read.

DVD Movie ‘Freezes’ momentarily Half Way Through

November 27, 2006

This is normal on dual-layered DVDs. Most commercial DVDs are dual-layered. The pause occurs as the laser changes angle to read the second layer. If a DVD properly mastered you won’t notice the pause, but sometimes it’s difficult to avoid. This is normal and the way dual-layer DVDs are designed, meaning nothing is wrong with the DVD itself. However, if the movie is pausing or freezing throughout the film, the DVD disc itself may be damaged.

November 27, 2006

PCs without virus protection are the most likely to become zombies, but even a protected PC can be infected if its antivirus software’s virus definitions are out of date or don’t properly detect certain compressed files.

[http://isc.sans.org/diary.php?date=2004-10-11]from handler Deb Hale at the ISC:

“…Has your hosts file been rewritten? C:\windows\system32\drivers\etc

“…Do you have a lot of unidentified connects to the system? – Start – Run – cmd, at the command prompt type                   netstat -an. Take a look at the devices that are listed. Do you recognize all of the ips?

“…If you go into windows task manager (right-click taskbar, choose ‘task manager’) do you see any processes running that you don’t recognize?

“…If you are comfortable with regedit, go to HKEY_LOCAL_MACHINE – software – microsoft – windows – current version. You should see run and run once and run services, (you may or may not see run services). Do you see any entries that you don’t recognize or look suspicious?”
