  • MacDrive 10 Pro gives you the power of Mac RAID on your Windows PC. With MacDrive 10 Pro, you can access Apple formatted RAID disks as well as RAID sets created with SoftRAID. You can also securely delete files and folders from your disk and easily create ISO images and mount sparse images.
  • Open the Disk Utility app on your Mac using one of the following methods, depending on the type of disk or volume you want to erase: If you want to erase your startup disk or startup volume: Start up from macOS Recovery, then choose Disk Utility from the macOS Utilities window.

Additionally, sparse bundle disk images work well with the Compact Image command. Compatible with Mac OS X 10.5 and later. Sparse disk images are stored as a single file. This can make backups inefficient for large disk images, because the entire file must be copied each time.

A sparse image is a type of disk image file used on macOS that grows in size as the user adds data to the image, taking up only as much disk space as stored in it. Apple mac wired keyboard. Encrypted sparse image files are used to secure a user's home directory by the FileVault feature in Mac OS X Snow Leopard and earlier. Sparse images can be created using Disk Utility.

Unlike a full image file (.dmg), which takes up as much actual space as the real disk it represents (regardless of the amount of unused space), a sparse image file (.sparseimage) takes up only as much actual disk space as the data contained within, up to a maximum of the capacity assigned during creation.

Limitations[edit]

  1. A customized '.sparseimage' image file can be assigned a larger total capacity than the physical volume (or HD partition) on which it originally resides. While the virtual volume will seem to make that capacity available, attempting to exceed the physical capacity of the underlying volume will result in a disk error: 'ran out of space'. The .sparseimage file must first be moved to a larger physical disk or partition.[citation needed]
  2. As noted above, while mounted .sparseimage image files automatically expand to their preassigned limit when data is added, they cannot be arbitrarily resized without the use of Disk Utility, hdiutil, or other such software.[1][2]

Sparse bundle disk images[edit]

Mac OS X Leopard introduced the concept of the sparse bundle.[3] Instead of a single big file, a sparse bundle is a bundle (directory) containing a number of files called bands, each on the order of 8 MB in size. This means even though to the end user the sparse bundle appears as a single file, it is composed of smaller files. As of Mac OS X 10.8, the bands are 8 MiB (8 × 10242 byte) each. When the content of the image changes, one or more band files is changed, created, or deleted. This allows backup software (such as Time Machine) to operate more efficiently.

Better blocker 2020 2. Sparse bundle advantages for Time Machine:

  • the backup destination no longer needs to be a Hierarchical File System (HFS) volume (for the hard links to work and to preserve metadata), but can be any shared folder, on any server, connected using any protocol and using any file system to store the actual files
  • the entire sparse bundle is replicable from one location to another; this is particularly useful when upgrading the backup storage and when the on-site backup storage needs to be replicated to an off-site backup storage. A tool such as rsync may be used to keep one or more disk images consistent across various systems.[4]

Resize a Sparse Bundle Image using Terminal

Apple Sparse Disk Image Media Software

A Sparse Bundle Image will increase in size automatically but will not shrink automatically. Before shrinking the sparse bundle, mount it and empty the trash to get rid of any deleted items from the image.

Unmount the image and follow the commands below. https://coolmfiles253.weebly.com/fs-4-0-24-kg.html.

To compact (image size stays the same):
hdiutil compact ~/Documents/filename.sparsebundle
hdiutil compact -help (for a list of options)

Magic mouse apple com. To increase the image size (eg., 20G to 30G)
hdiutil resize -size 30g ~/Documents/filename.sparsebundle
hdiutil resize -help (for a list of options)

Mount the image then do a Get Info on the Volume to see the new size.
