It appears in the collection The Book of Sand book The Book of Sand . Synopsis The story deals with a woodcutter who lives in the midst of a deep wood in old England and who has never seen the sea. He tells the reader that at one time a man, who asks lodging from him appears at his door. The woodcutter notes that the man was elderly, as he referred to England as Saxony , which, at the time, was a sign of age. The day after the man wishes to leave, but before he does, he says that he is a King and is descended from Odin . He tells the woodcutter that he is exiled, but that he shall always be a king, because he holds the Disk of Odin, the sole thing in the world that has but one side. He opens his hand and shows the disk the woodcutter sees only an empty palm, but thereafter touches it, feeling a chill in the fingers and seeing a flash. He makes a false claim that he has a full chest of gold and wants to trade it for the disk, because he knows the man will decline. And the man does, to which the woodcutter replies that the man may go. When he turns around, the woodcutter kills the man with an axe. He then drags the body and throws it into the river. He then comes back and searches for the disk, which he never finds.

  1. Disk swapping

    Disk swapping refers to the practice of inserting and removing, or swapping, floppy disks in a floppy disk drive based computer system . In the early days of personal computer s, before hard drives became commonplace, most fully outfitted computer systems had 2 floppy drives addressed as A and B on CP M and MS DOS. Disk drives were expensive, however, and having two was seen as a luxury by many computer users who had to make to with a single drive. The purpose of 2 floppy drives was so that the disk containing the Application software application program could remain in the drive while the data disk containing the user s files could be accessed in the second drive. In order to use a function of the program not loaded into memory, the user would have to first remove the data disk, then insert the program disk. When the user then wanted to save their file, the reverse operation would have to be performed. On some less than user friendly systems, this could result in data loss when, for example, files were saved onto the program disk. Disk swapping was an infamous feature of early Macintosh 128k systems, which were extremely RAM starved. Category Floppy disk computer storage ...   more details

When the removable cartridge was inserted into the cartridge drive peripheral device , the disk read and write head read write head s of the drive could access the magnetic data storage device data storage surface of the platter through holes in the shell. The disk cartridge was a direct evolution from the disk pack drive, or the early hard drive .

  1. F6 disk

    F6 disk is a colloquial name for a floppy disk containing a Microsoft Windows NT device driver for a SCSI or RAID system. F6 disks are used by all NT based versions of Windows, including Windows 2000 , Windows Server 2003 , and Windows XP . Starting with Windows Vista , floppy F6 disks are obsolete its setup process supports loading third party drivers from USB flash drive USB drives and CD ROM CD ROMs . Usage An F6 disk is named after the manner in which it is used. During the installation process for Windows, the Setup program must load device drivers for the disk system on which Windows will be installed. Unless the disk system has been established on the market before the finalization of the particular Windows release being installed, the drivers are not included on the Windows installation discs, and they must be loaded by means of an F6 disk. An F6 disk is loaded in Windows setup by pressing the Function key F6 key immediately when Windows Setup starts. The message Press F6 if you need to install a third party SCSI or RAID driver... is briefly flashed on the screen every time Windows Setup starts. An F6 disk contains device drivers in its root directory . Prior to Windows Vista, F6 disks were always floppy disks because, at the point the F6 prompt is shown, Windows Setup has not loaded the drivers for any media type other than floppy disks. Support for USB drives and CD ROMs was added in Windows Vista. Device drivers for RAID and other disk controllers are often provided on CD ROMs by the manufacturers, but they must be copied to an F6 disk if they are to be used during Windows Setup. An alternative approach is to slipstream computing slipstream the required SATA SCSI SAS RAID EIDE drivers into the Windows installation files directory e.g. i386 for the x86 variety by means of software like nLite and then create an ISO image that can be burned to CD or DVD media.

Early disk controllers were identified by their storage methods and data encoding. They were typically implemented on a separate controller card. Modified frequency modulation MFM controllers were the most common type in small computers, used for both floppy disk and hard disk drives. Run length limited RLL controllers used data compression to increase storage capacity by about 50 . Priam created a proprietary storage algorithm that could double the disk storage. Shugart Associates Systems Interface Shugart Associates System Interface SASI was a predecessor to SCSI . Modern disk controllers are integrated into the disk drive. For example, disks called SCSI disks have built in SCSI controllers. In the past, before most SCSI controller functionality was implemented in a single chip, separate SCSI controllers interfaced disks to the SCSI bus. The most common types of interfaces provided nowadays by disk controllers are Parallel ATA PATA IDE and Serial ATA for home use. High end disks use SCSI , Fibre Channel or Serial Attached SCSI . Disk controller versus host adapter The correct term for the components that allows a computer to talk to a peripheral bus is host adapter or host bus adapter HBA . On the other hand, a disk controller allows a disk to talk to the same bus. Those two are often confused, especially in the Advanced Technology Attachment PC world . In fact signals read by a disk read and write head are converted by a disk controller, then transmitted over the peripheral ..., and then read by the CPU .
