Main Linux filesystem having support for efficient sparse file handling is Handling Large Sparse Files ¶Īs of today Linux provides inadequate support for managing (tar,Ĭp, gzip, gunzip, bzip2, bunzip2, cat, etc) large sparse files. NTFS 3G FIX COMMAND ISOAll major Linux filesystem like,Įxt2, ext3, reiserfs, Reiser4, JFS and XFS, supports sparse files but forĮxample the ISO 9600 CD-ROM filesystem doesn't. The du command can tell the real disk space used by a sparseįile. Reported size of such files are always higher than the disk space consumedīy them. Sparse Files ¶Ī file is sparse if it has unallocated blocks (holes). NTFS 3G FIX COMMAND WINDOWSHereby ntfsclone can be used as a very fast and reliable buildīlock for Windows cloning but itself it's not enough. Its aim is only NTFS cloning, not WindowsĬloning. This is by design: ntfsclone is aįilesystem, not system utility. The ntfsclone utility guarantees to make an exact copy of NTFS but Same type of disk having the same BIOS legacy cylinder setting as the Or restore NTFS to the same partition which starts at the same sector on the Usually, Windows will not be able to boot, unless you copy, move Hda1->hdb1 or to a different disk sector offset) then you will need to If you want to copy, move or restore a system or boot partition toĪnother computer, or to a different disk or partition (e.g. ![]() Mount -t ntfs -o loop ntfsclone.img /mnt/ntfsclone For example if you clone toĪ file and the kernel has loopback device and NTFS support then the file can Mounted just like the original NTFS filesystem.
