  • Disk Management (4 Min) When We Want to Install a Hard Drive in Our System We're Going to Need to Make That Hard Drive Either a Basic Disk Or a Dynamic Disk
    Video – Disk Management (4 min) When we want to install a hard drive in our system we're going to need to make that hard drive either a basic disk or a dynamic disk. A basic disk, which is the default, contains primary and extended partitions as well as logical drives. A basic disk is limited to four partitions. The Windows operating system needs to be installed onto a basic disk. After it's installed the basic disk can then be converted to a dynamic disk. Primary partition. The primary partition contains the operating system. There can be up to four primary partitions per hard drive and a primary partition cannot be subdivided into smaller sections. A primary partition can also be marked as the active partition. The operating system uses the active partition to boot the computer. Only one primary partition per disk can be marked as active. In most cases, the C: drive is the active partition and contains the boot and system files. Meaning the MBR or Master Boot Record Partition Table. Newer systems that use EFI instead of BIOS are using the GPT or GUID partition table. If you're using the GPT instead of the MBR partition table you can have more than four primary partitions on a disk. An extended partition. There can only be one extended partition per hard drive. Once again, primary partitions, active partitions and extended partitions are all part of a basic disk. An extended partition cannot hold the operating system, but it can be subdivided into smaller sections called logical drives.

Why is this? Why have so many sys- ity, rather than that of being the state of the tem administrations and users put their trust in art in filesystem technology. Over the last few the ext2/3 filesystem? years, however, there has been a significant amount of development effort towards making There are many possible explanations, includ- ext3 an outstanding filesystem, while retaining ing the fact that the filesystem has a large and these crucial advantages. In this paper, we dis- diverse developer community. However, in cuss those features that have been accepted in our opinion, robustness (even in the face of the mainline Linux 2.6 kernel, including direc- hardware-induced corruption) and backwards tory indexing, block reservation, and online re- compatibility are among the most important sizing.

  • Design and Implementation of the Spad Filesystem
    Charles University in Prague Faculty of Mathematics and Physics DOCTORAL THESIS Mikul´aˇsPatoˇcka Design and Implementation of the Spad Filesystem Department of Software Engineering Advisor: RNDr. Filip Zavoral, Ph.D. Abstract Title: Design and Implementation of the Spad Filesystem Author: Mgr. Mikul´aˇsPatoˇcka email: [email protected]ff.cuni.cz Department: Department of Software Engineering Faculty of Mathematics and Physics Charles University in Prague, Czech Republic Advisor: RNDr. Filip Zavoral, Ph.D. email: Filip.Zavoral@mff.cuni.cz Mailing address (advisor): Dept. of Software Engineering Charles University in Prague Malostransk´en´am. 25 118 00 Prague, Czech Republic WWW: http://artax.karlin.mff.cuni.cz/~mikulas/spadfs/ Abstract: This thesis describes design and implementation of the Spad filesystem. I present my novel method for maintaining filesystem consistency — crash counts. I describe architecture of other filesystems and present my own de- sign decisions in directory management, file allocation information, free space management, block allocation strategy and filesystem checking algorithm. I experimentally evaluate performance of the filesystem. I evaluate performance of the same filesystem on two different operating systems, enabling the reader to make a conclusion on how much the performance of various tasks is affected by operating system and how much by physical layout of data on disk. Keywords: filesystem, operating system, crash counts, extendible hashing, SpadFS Acknowledgments I would like to thank my advisor Filip Zavoral for supporting my work and for reading and making comments on this thesis. I would also like to thank to colleague Leo Galamboˇsfor testing my filesystem on his search engine with 1TB RAID array, which led to fixing some bugs and improving performance.

    LINUX: Rute User’s Tutorial and Exposition Paul Sheer August 14, 2001 Pages up to and including this page are not included by Prentice Hall. 2 “The reason we don’t sell billions and billions of Guides,” continued Harl, after wiping his mouth, “is the expense. What we do is we sell one Guide billions and billions of times. We exploit the multidimensional nature of the Universe to cut down on manufacturing costs. And we don’t sell to penniless hitchhikers. What a stupid notion that was! Find the one section of the market that, more or less by definition, doesn’t have any money, and try to sell to it. No. We sell to the affluent business traveler and his vacationing wife in a billion, billion different futures. This is the most radical, dynamic and thrusting business venture in the entire multidimensional infinity of space-time-probability ever.” ... Ford was completely at a loss for what to do next. “Look,” he said in a stern voice. But he wasn’t certain how far saying things like “Look” in a stern voice was necessarily going to get him, and time was not on his side. What the hell, he thought, you’re only young once, and threw himself out of the window. That would at least keep the element of surprise on his side. ... In a spirit of scientific inquiry he hurled himself out of the window again. Douglas Adams Mostly Harmless Strangely, the thing that least intrigued me was how they’d managed to get it all done. I suppose I sort of knew.
