	Disk Drive TuneUp for Mac - Softwarestore.com
		Disk Drive TuneUp v.3 is the world's first disk drive utility that provides integrated use of the new UDF format for cross platform disk interchange for all types of block addressable storage devices.
		Originally specified for DVD, the UDF format is fast becoming the new international format standard for all types of storage devices because of its ability to provide compatibility between different computers and operating systems.
		Disk Drive TuneUp is the only general storage utility that can ensure read & write compatibility of UDF formatted disks between Apple Macintosh and MS Windows computer systems.

	Universal Disk Format - Wikipedia, the free encyclopedia
		UDF is developed and maintained by the Optical Storage Technology Association (OSTA).
		UDF is practically the successor of ISO 9660, supporting larger files, larger disk and more information about individual files and folders.
		RW disks may be formatted in the plain UDF flavor, in the VAT flavor and in the Spared flavor.

		UDF lets both CD and DVD formats use MPEG (Moving Pictures Experts Group) files and ensures that DVD and CD formats remain compatible across all PC platforms.
		UDF also lets CD-R and CD-RW take advantage of packet writing, a process that makes writing to CD faster and more space efficient than it was under the older standards.
		Although UDF works with both DVD and CD, it is absolutely required only on DVD-ROM media, since it is needed to store MPEG audio and video streams.

	Disk Imaging in Windows - Increases user productivity and permits broader range of backup devices with CDR, CDRW, DVD ...
		Companies and individuals that had mirror images of disk drives found that they were able to get back up far more quickly than their counterparts who had only data backups.
		In cases where the user's hard disk is partitioned only as one drive, that meant the user could not image their system at all from within Windows.
		If the disk is large enough, it could mean that the user is out of commission for hours at a time while the program chugged away at creating an image.

		Universal Disk Format (UDF) is the filesystem used on DVDs.
		UDF implementations provided by various software vendors may or may not fully comply with the UDF standard, resulting in frustrating incompatibility problems that are difficult to diagnose.
		Originally specified for DVD, the UDF format is fast becoming the new international format standard for all types of storage devices because it can handle larger and more complicated files and it helps ensures that disks can be interchangeable with all types of computer systems, on large storage devices and consumer digital appliances.

		The goal of the OSTA Universal Disk Format (UDF) specification was to develop a practical subset of the NSR standard that would be much easier to bring to market, while also addressing how data is to be interchanged between systems.
		UDF provides the long term assurance that your archived data can be read many years down the road thus protecting your valuable information while maintaining full compliancy with regulations and laws governing information retention.
		UDF was designed to meet the mass storage needs of a global community well into the future.

		(n.) Abbreviated as UDF, a universal vendor-independent file system for optical media designed for data interchange and portability, allowing an operating system to read, write and modify data stored on optical media that was created by another operating system.
		DVDs are based on the UDF format and CD-R and CD-RW disks use UDF as an optional second standard.
		UDF, defined by the Optical Technology Storage Association (OTSA), is a subset of ISO 13346, an interchange standard for non-sequential recording of data.

	The Universal Disk Format. UDF File System Recovery
		This means that the original UDF format can only be written to CD-Rs by pre-mastering the data and then writing all data in one piece to the media, similar to the way ISO 9660 gets written to CD media.
		RW disks may be formatted in the original UDF format, in the VAT flavor and in the Spared flavor.
		When using the original format, in theory a disc driver may allow to rewrite any disc sector at random, meaning the RW is truly rewritable in the fashion of hard disks.

		The Windows Vista Disk Defragmenter was simplified primarily for the purpose of removing it out of the face of the user.
		Using low priority CPU and disk I/O does not prevent Defrag from using more system resources when you are not using the computer, such as when the scheduled defrag runs overnight.
		If Disk Defragmenter doesn’t finish a run between one run of “idle” and “not idle,” Task Manager will wait for the next idle condition, wait for any tasks ahead of the ScheduledDefrag in the Task Scheduler queue, and then fire up another ScheduledDefrag task.

	Mount Rainier (packet writing) - Wikipedia, the free encyclopedia
		The physical format of MRW disks is an extension of the UDF format, but this is transparently managed internally by drive intelligence which remaps physical drive blocks into a virtual and defect-free space.
		The time needed for the formatting of the disk is shortened to about one minute by the background formatting capabilities of the drive.
		Formatting allocates some sectors at the end of the disk for defect management.

		A CD burnt on a Windows XP system uses ISO 9660 format by default (this format uses the CDFS file system) and can be recognised by Mac OS X. The DVD standard file format is called Universal Disk Format (UDF) which is available on both Mac and PC.
		With USB devices such as Zip drives, hard disk drives, CD-R/Ws or PDAs, usually all you have to do is connect the device to the Macintosh and it is automatically recognised.
		For the majority of external devices, no driver installation is required; however, for hard disks, bear in mind that Mac OS X cannot open NTFS formatted disks, so please use the FAT PC format instead.
