A hard disk drive failure occurs when a hard disk drive malfunctions and the stored information cannot be accessed with a properly configured computer. A hard disk failure may occur in the course of normal operation, or due to an external factor such as exposure to fire or water or high magnetic fields , or suffering a sharp impact or ...
Spin-up refers to the process of a hard disk drive or optical disc drive accelerating its platters or inserted optical disc from a stopped state to an operational speed. The required operational speed depends on the design of the disk drive. Typical speeds of hard disks have been 2400, 3600, 4200, 5400, 7200, 10000 and 15000 revolutions per ...
2003 Launch of 500 GB external Hard Drive: LaCie Big Disk; portable drives designed by F.A. Porsche line of storage solutions; first Triple Interface Hard Drives. [citation needed] 2004 1 TB external Hard Drive the LaCie Bigger Disk. [citation needed] 2009 LaCie acquires Caleido, a peer-to-peer storage start-up, with their product named Wuala.
The rotational mechanism in an optical drive differs considerably from that of a hard disk drive's, in that the latter keeps a constant angular velocity (CAV), in other words a constant number of revolutions per minute (RPM). With CAV, a higher throughput is generally achievable at the outer disc compared to the inner.
" Gretchen am Spinnrade" (Gretchen at the Spinning Wheel), Op. 2, D 118, is a Lied composed by Franz Schubert using the text from Part One, scene 15 of Johann Wolfgang von Goethe's Faust. With "Gretchen am Spinnrade" and some 600 other songs for voice and piano, Schubert contributed transformatively to the genre of Lied .
All celestial objects – planets, stars , galaxies, black holes – spin. [1] [2] [3] The boundaries of a Kerr black hole relevant to astrophysics. Note that there are no physical "surfaces" as such. The boundaries are mathematical surfaces, or sets of points in spacetime, relevant to analysis of the black hole's properties and interactions.
Accretion disks are usually assumed to be threaded by the external magnetic fields present in the interstellar medium. These fields are typically weak (about few micro-Gauss), but they can get anchored to the matter in the disk, because of its high electrical conductivity , and carried inward toward the central star .
The scenes in which Lacie is driving utilise a computer-generated landscape designed by Dan May, the episode's art director. [17] She was initially planned to drive through multiple landscapes such as a desert, but this was changed for budget reasons. [2] Bryce Dallas Howard plays Lacie, the episode's main character.
