A process that prepares a hard drive to store data.
formatted capacity
The actual capacity available to store data in a mass storage device. The formatted capacity is the gross capacity minus the capacity used by overhead (formatting).

File Transfer Protocol. A network protocol used to transfer data from one computer to another through a network. FTP is a popular choice for exchanging files independent of the operating systems involved.
full-duplex
A communication protocol that permits simultaneous transmission in both directions.
I’m looking to automate some printing in Windows 7. Ideally from command line. Just as if I would’ve right-clicked and selected “Print”. Tried the command: C:>print /D:”CutePDF Writer” test.txt That printer is supposed to created PDF files (like the XPS printer) but haven’t managed to get anything show up in the printer queue. Ideas?

I was wondering how low you could go with hardware that would still be able to smoothly run HD movies. My current plan is around $215 CAD w/o a hard drive: Intel Pentium 4 @ 3.2 GHz – 1GB DDR/SDRAM – 512MB X1600 Pro AGP – 350W PSU – ECS P4VXASD2+ – Bluray/DVD-RW drive. As…
Linux file structure files are grouped according to purpose. Ex: commands, data files, documentation. Parts of a Unix directory tree are listed below. All directories are grouped under the root entry “/”.
root – The home directory for the root user
home – Contains the user’s home directories along with directories for services
bin – Commands needed during bootup that might be needed by normal users
sbin – Like bin but commands are not intended for normal users. Commands run by LINUX.
proc – This filesystem is not on a disk. It is a virtual filesystem that exists in the kernels imagination which is memory.
usr – Contains all commands, libraries, man pages, games and static files for normal operation.
boot – Files used by the bootstrap loader, LILO. Kernel images are often kept here.
lib – Shared libraries needed by the programs on the root filesystem
dev – Device files
etc – Configuration files specific to the machine.
var – Contains files that change for mail, news, printers log files, man pages, temp files
file
mnt – Mount points for temporary mounts by the system administrator.
tmp – Temporary files. Programs running after bootup should use /var/tmp.
We first look at the following two pictures. Picture 1 is the “BIOS CHIP” of the circuit board. When we replace the PCB, we need to swap the “BIOS CHIP” with your original PCB. Picture 2 shows the “Board Number” of the board, and the “Board Number” must be the same! FAQs of 2060-771961-000 PCB…
If you’ve ever installed a hard drive, you have noticed the green board on the bottom of the drive. The green board is known as the hard disk drive’s PCB (Printed Circuit Board).
What A Hard Drive PCB Does?
The PCB is more than a simple way for a hard drive to contain power; it often contains part of the firmware of a drive, which lets the hard drive know how to operate properly and how to read data from the platters. For instance, part of its function is to store information about how many heads are contained within the drive, unique adaptive, and how to access continued microcode for successful drive start-up.
This information is put onto each PCB at the factory, and is programmed to be very specific to the particular hard drive for which it’s designed. While this may sound inefficient, it’s actually the culmination of dozens of years of hard drive technology; it allows larger and larger drives to be built that are both accurate and dependable.
PCB is one of the most complex and intriguing parts of a hard drive. When hard drives fail, occasionally it’s due to a malfunction of the PCB board. Power surges can cause this type of a failure, as well as dust contamination and many other common computer problems.
Hard Drive PCB Failure Symptoms
Hard drive PCB failures usually render a drive unable to boot up. Depending on the brand and model of the drive, some PCB problems cause a hard drive’s information to display inaccurately in the BIOS.
Swapping Out a Hard Drive’s PCB
Because of this customized firmware, however, it’s not possible to switch out a PCB board in many cases; of course, this varies depending on the manufacturer of a drive. For instance, some older drives have the same basic information on two PCB boards of the same model, provided that both drives were made at about the same time, before more unique adaptive were programmed into the next line of drives. If one of the PCBs fails, there is some chance of making a recovery by simply swapping the boards of the two drives. However, hard drives have contained “customized” firmware on at least an occasional basis since they’ve become a consumer product, so the chances of a straight “board swap” working are very low. In most cases, when you swap the PCB, you should also exchange the BIOS which includes the unique information.
