Endre størrelse på partisjon

[YBD]

Hei!

 

Jeg har en litt gammel 450mhz maskin med en harddisk på 17 gb. Den har to partisjoner, C: og E: på cirka 8 gb. Har nå slettet E: for å slå de sammen til en partisjon. Her kommer problemet.

 

På C: (NTFS-partisjon) ligger operativsystemet, Windows XP Pro. Jeg bruker Partition Magic 7 Pro for å resize.

 

Dette er meldingen som kommer:

"Resizing or movin an operating system partition beyond the 1024 cylinder boundary may make the computer unbootable. Due to INT13 BIOS limitations on some machines, your rescue diskettes may not be able to recover from this situation."

 

Hvorfor?

Er det trygt å resize den?

Fikk ikke mye svar her nei.

Spurte på irc, og der ble jeg anbefalt å gjøre det - det var veldig lite sannsynligvis at det ville gå galt.

 

Så jeg gjorde det selv om jeg ble advart, og det funker helt perfekt :smile:

Men først oppdaterte jeg bios til nyeste versjon.

Jeg tror det skal gå fint. Det er bare å sjekke hjelpefila og slå opp på "Understanding the BIOS 1024 Cylinder Limit":

 

The BIOS 1024 cylinder limitation exists because the start and end cylinder values in the partition table (and some BIOSs) have a maximum value of 1024. Because some operating systems such as DOS 6.22 use the CHS (Cylinder, Head, and Sector) values to address sectors on the disk, they cannot access sectors beyond the 1024 cylinder. When you start your computer the BIOS boots the operating system using the CHS values to locate the first sector of the bootable partition. If the partition starts past the 1024 cylinder, the BIOS may not be able to boot it because it cannot address a cylinder number higher than 1024.

 

With PartitionMagic, you can safely partition any drive, regardless of the number of cylinders on the drive. In fact, to prevent you from performing partition operations that might cause problems, PartitionMagic is careful to observe the BIOS 1,024 cylinder limit on computer systems where one or more of the following applies:

 

· The hard disk has a capacity 504 MB or more and the BIOS translation mode is set to Normal or CHS.

 

· The hard disk has a capacity 504 MB or more and the BIOS was manufactured prior to 1994 (approximately).

 

· The hard disk has a capacity 8 GB or more.

 

If you have such a computer system and you use only DOS, neither the DOS FDISK utility nor PartitionMagic lets you see cylinders beyond the 1,024th cylinder or include them in any partition. Space beyond the 1,024th cylinder always remains invisible.

Even if the BIOS 1,024 cylinder limit applies to your system, you can use PartitionMagic without difficulty. The only instance where you may encounter a problem is if all the following criteria apply:

 

· You use DOS and another OS.

 

· The other OS can "see" and use disk space past the first 1,024 cylinders on the disk.

 

· You use PartitionMagic or the FDISK utility of the other OS to create a partition extending beyond the 1,024th cylinder.

 

· You then run the DOS PartitionMagic executable.

 

When you run the DOS PartitionMagic executable, you may or may not be able to see the newly-created partition that extends beyond the 1,024 cylinder limit. Even if you can see the partition, you cannot use the DOS PartitionMagic executable to perform any operations on that partition. This restriction applies to both primary and extended partitions that contain space beyond the 1,024th cylinder. If an extended partition exceeds the cylinder limit, you cannot perform operations on any one of the contained logical partitions, even if the logical partition itself does not extend past the 1,024th cylinder.

 

The disk map in the PartitionMagic main window displays an arrow indicator at the 1024 cylinder boundary (and the 2 GB boot boundary), so you can see where your partitions are located relative to the 1024 cylinder limit. Be sure that all OS partitions on a disk start prior to cylinder 1024. This ensures that you can boot the OS. Also, use caution when moving a bootable partition; if the partition is moved beyond cylinder 1024 it may no longer be bootable. To fix this problem you can move the partition below the 1024 cylinder marker.

 

Tips

 

· If you use DOS, but your system has the INT 13 BIOS extensions, PartitionMagic lets you see cylinders past the normal 1,024 limit and perform operations on partitions extending beyond this boundary.
