HardDisk begrænsninger

Bob og jeg har talt lidt om Harddisk begrænsninger (de fleste har vel hørt/prøvet 137Gb begrænsningen)

Her er hvad vi kom frem til:

***begrænsninger***
10Mb
PC/XT

16Mb
FAT12

32Mb
DOS3.X

128Mb
DOD 4.X

528Mb (504MiB)
ATA BIOS uden "extensions"
1024 Cylindre x 16 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

2.1Gb (1.97GiB)
DOS fil systems partionering
4096 Cylindre x 16 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

2.15Gb (2GiB)
FAT16 (32k klustere) (DOS, Win3.X og Windows 95A) 4.3Gb (4Gb) for 64k klustere i Windows NT)

3.26GB (3.04GiB)
BIOS problem (ikke ret udbredt)
6322 Cylindre x 16 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

3.28GB (3.05GiB)
Phoenix BIOS V4.03-04 problem
6349 Cylindre x 16 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

4.23Gb (3.94GiB)
CMOS udvidet CHS addressering (BIOS/OS problem)
8192 Cylindre x 16 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

8.46Gb (7.88GiB)
BIOS/Int13h (BIOS/OS problem)
1024 Cylindre x 256 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

32Gb (29.8GiB)
Windows 95 problem

33.82Gb (31.5GiB)
Award BIOS problem
65,535 Cylindre x 16 Hoveder x 63 Sektorer x 512 bytes (pr sektor)

137.4Gb (128GiB)
28bit LBA BIOS
268,435,456 (2^28) sektorer af 512 bytes pr stk

2.2Tb
(begrænsning i 32bit styresystemer)

144Pb 48bit
ATA/ATAPI-6


Størrelser:

Megabyte 1 Megabyte = 1.000.000 bytes MB mega: (10^3)^2
Gigabyte 1 Gigabyte = 1.000.000.000 bytes GB giga: (10^3)^3
Terabyte 1 Terabyte = 1.000.000.000.000 bytes TB tera: (10^3)^4
Petabyte 1 Petabyte = 1.000.000.000.000.000 bytes PB peta: (10^3)^5

Størrelser i (parentes):

1 Mebibyte = 1.048.576 bytes MiB megabinary: (2^10)^2
1 Gibibyte = 1.073.741.824 bytes GiB gigabinary: (2^10)^3
1 Tebibyte = 1.099.511.627.776 bytes TiB terabinary: (2^10)^4
1 Pebibyte = 1.125.899.906.842.624 bytes PiB petabinary: (2^10)^5



Jeg glæder mig til at støde på 2.2Tb begrænsningen
