"This card cannot be used." when i insert a memory card into camera?
I had the same problem with my SanDisk mem card! I couldn't figure out a way to fix it so I bought a Kodak mem card and haven't had any problems! =]
Can I say that the hex address of something in memory, when translated into decimal, is the "-th" byte in memory?
It’s not even the 140726248600408th byte of the address space of your current process.It doesn’t map directly to the physical memory of the laptop. Typically, various process pages are mapped as required to physical memory, and they can even move about while you’re not looking. The operating system kernel decides where to put pages in physical memory, and configures the memory management unit accordingly, which actually performs the mundane mapping of virtual addresses to physical addresses.The reason some numbers are so high is that the operating system kernel keeps different areas of memory for different purposes. The stack, for instance, is usually quite high, whereas the heap is in the middle, and the code quite low - but shared libraries, on the other hand, are quite high up.On Linux, the “pmap” command can tell you what’s put where. You’ll generally see that your process memory is not contiguous - there are all sorts of odd holes everywhere. Most obviously, there’s almost always a massive hold in the middle, but there’s often large holes elsewhere, too.However, you can still treat pointer values as integers to play with (if you’ve a good reason to do so), so the general model holds for most purposes.
What does "Memory distortion" mean??
It is pretty much just what it sounds like. It is when people have a memory that has been somehow tampered with and they are given a new 'memory' that is no longer accurate. People do this to protect themselves (remembering someone who abused them as 'doting and special' instead of seeing the behavior as abusive), or to explain something they can not otherwise categorize ('remembering' abuse as a reason for a current problem). Sometimes it can be implanted by another person (perhaps an abuser), almost like hypnosis or sometimes it can be created by a series of lies that become so ingrained, they become true to the person telling them. All these things can affect memory and it creates a distortion in the mind of the person. Good luck with that paper :)
Is there something wrong with my RAM?
If the memory module is labeled properly, then you have the right type of memory in your computer. In your second line, where you see "PC3-10600" that is the nomenclature for DDR-1333 memory. As long as the label is true (and wasn't replaced or tampered with), then your memory is certainly the right speed. So, at least we know the hardware included should be OK. The other thing you need to know is that DDR, DDR2 and DDR3 run at DOUBLE the clock rate... so while your clock speed is listed at 648 MHz your effective clock speed is right around 1300 MHz (well within where it should be.)

How to create Bad Sectors on a Hard Drive? YES CREATE THEM NOT FIX THEM!?!?
In continuation of someone elses answer here, to do a low-level format which is unheard of today because it is unnecessary, use a utility called dban. This will erase any data on the drive making it cean enough for any use. This assumes you are trying to clean the drive.
