Welcome to our web site! ΠΩΣ ΕΠΙΣΚΕΥΑΖΕΤΕ ΕΝΑΣ ΣΚΛΗΡΟΣ???
Βέβαια
τα platters ενός δίσκου δεν είναι
μέσα σε κενό αέρα, αλλά απλώς
ο αέρας που περνάει μέσα
φιλτράρεται και είναι όσοτο
δυνατό καθαρός. Έτσι αν κάποιος
πάρει κάποιες προφυλάξεις
(γάντια, καθαρό αέρα, κλειστά
airconditions κλπ) γίνεται να ανοίξει
τον δίσκο. Some people believe a disk drive contains a vacuum
— this is incorrect, as the system relies on air pressure inside the drive to support the heads at their proper flying
height while the disk is in motion.
Another common misconception is that a hard drive is totally sealed. A hard disk drive
requires a certain range of air pressures in order to operate properly. If the air pressure is too low, the air will not
exert enough force on the flying head, the head will not be at the proper height, and there is a risk of
head crashes
and data loss. (Specially manufactured sealed and pressurized drives are needed for reliable
high-altitude operation,
above about 10,000 feet.) Some modern drives include flying height sensors to
detect if the pressure is too low, and temperature
sensors to alert the system to overheating problems.
Hard disk drives are not airtight. They have a permeable filter (a
breather filter) between the top cover and inside of the drive, to allow the pressure inside and outside the drive to equalize
while keeping out dust and dirt. The filter also allows moisture in the air to enter the drive. Very high humidity
year-round will cause accelerated wear of the drive's heads (by increasing stiction, or the tendency for the heads to stick
to the disk surface, which causes physical damage to the disk and spindle motor). You can see these breather holes on all
drives -- they usually have a warning sticker next to them, informing
the user not to cover the holes. The air inside
the operating drive is constantly moving too, being swept in motion by friction with the spinning disk platters. This air
passes through an internal filter to remove any leftover contaminants from manufacture, any particles that may have somehow
entered the drive, and any particles generated by head crash.http://www.economicexpert.com/a/Hard:disk.htmlΠερισσότερα γιά επισκευή
