comment Is there a shortcut to open Command prompt in Administrator mode
@DanielB: I'm 99% sure you're right, but not at a PC to verify.

comment What is the difference between a quick and full format?
Full formats on Windows did not write zeros to the entire drive until Vista. KB941961

comment Can SSD raid be faster than ramdisk?
@PeterHorvath: Latency is still a big deal with SSDs. Look at all the research and benchmarks into consistency and the stuttering problems that early SSDs had. And as Michael Kjörling mentioned, RAM latency is several orders of magnitude lower than SSD. Latency on Lx caches is significantly lower still, and CPU register latency is even lower yet. And it all matters for performance.

comment How much memory does Windows 7 64x use for itself?
SQL Server will use all the memory it can unless you've configured constraints on usage.

comment How to preserve file attributes when one copies files in Windows?
@megamorf: In what way does robocopy do anything special? It doesn't do any checksumming or hashing of the data, it relies on the OS to report errors just like almost any other program.

comment Installing IE 8 on windows xp hangs forever
Run the IE setup with the /update-no command line option to keep it from looking for updates. Then do Windows Update later.

Yikes. System specs? Had it been updating successfully before?

comment What are the best options to use when compressing files using 7 Zip?
@endolith: bzip2, lzma, wv, and ppmd are all very recent additions to the file format. It's not even safe to assume that your recipient can handle deflate64, much less anything newer.

comment Can SSD raid be faster than ramdisk?
Any competent DBMS will keep as much of the DB in RAM as possible. If your DB is tiny enough to fit in a RAMdisk, it's tiny enough to just fit in RAM. Properly tuning your DBMS with an SSD will give you the performance you're looking for -- for local development, you can even take advantage of things like write back caching and worrying less about ACID. A RAMdisk is fighting the system.

comment Can SSD raid be faster than ramdisk?
@KorayTugay: Generally speaking, the answer to "Do I need a RAMDisk?" is almost always "No. If you really needed it, you'd know enough that you wouldn't have to ask." What are you doing that makes you think you'll need it?

comment SSD/HDD not exceeding 120 MB/s
AnandTech's Smasung 840 EVO Review shows how most current controllers hold up under sustained writes, and his Corsair Force LS Review shows how garbage collection starts working over the course of an HD Tach run. Tom's Hardware Link shows how the Marvell controller in the m4/M5S and the Samsung 830(!) maintain performance.

comment SSD/HDD not exceeding 120 MB/s
Between idle time garbage collection and SSD manufacturers concentrating on improving worst case small random write latency, you have to try to get an SSD since about mid-2011 into a pathologically bad state, and in the overwhelming majority of end user systems, there's plenty of idle time for garbage collection routines to do their work using the built-in spare area and free space. I haven't look at TRIM stats in a while because it's a solved problem, but links upcoming:

comment SSD/HDD not exceeding 120 MB/s
TRIM is much less important for modern SSDs since the garbage collecting and background maintenance routines are much better than with earlier drives. Also, Vista does not have TRIM support at all.

comment Building my own computer
An anecdote: Back in the 90s, I had the same quandry you did. I bought a CPU+MB only to have it lose half of its value over the next month while my build still sat unfinished. It was several hundred dollars I could have used for, well, anything else really. Save up first and buy everything you need at once. Your comopnents are going to lose value anyway, but you might as well be able to use them while they do.

comment Performance issues with Notepad++
Try toggling line wrapping and see if it helps. I think the biggest problem is simply attempting to measure the line width for the horizontal scrollbar. The Scintilla editing component that N++ (and many other editors) use simply doesn't consider extremely long lines to be a worthwhile use case to optimize performance for.

comment Missing MSVCR100.DLL
With recent versions of the Visual C++ Redistributables (since VS2005), security fixes can be installed without installing the prior version.

comment Compress the silence - audio file formats
The problem is that "silence" probably isn't digital silence, it's low-amplitude white noise. Most encoders are going to attempt to encode it and use much more space then necessary. Pre-processing your audio to turn that into digital silence and using a VBR encoding should get an encoder to use the minimum possible space.

comment Long running chkdsk on Windows 7 1TB external hard drive
IF it's your backup, then get a new disk and redo your backup. If the drive isn't completely worthless then it can be relegated to light duty.

comment why don't file search utilities just load and parse the MFT?
Tools like Everything and UltraSearch also parse the MFT (and in some cases the USN Journal) directly. However, sidestepping ACLs is the #1 reason you don't see more use made of this.
