	Drive letter assignment - Wikipedia, the free encyclopedia
		Drive letter assignment is the process of assigning drive letters to primary and logical partitions (drive volumes) in the root namespace; this usage is found in Microsoft operating systems.
		Drive letter assignment is thus a process of using letters to name the roots of the "forest" representing the file system; each volume holds an independent "tree" (or, for non-hierarchical file systems, an independent list of files).
		Assign the drive letter 'A' to the boot floppy, and 'B' to the secondary floppy.

	Drive letter assignment
		Drive letter assignment is the process of matching volumes (active primary partitionss and logical partitions) to letters in the root namespace of a file system as seen by a Microsoft operating system.
		The concept of drive letters might have originated in the CP/M operating system, in imitation of the device prefixes in the RSX-11 and VMS operating systems.
		Drive letters are however not a compulsory way of accessing different volumes.

	kbAlertz: In Windows 2000, all drive letters assigned to volumes are assigned by the Mount Manager (MountMgr) program. ...
		After a drive letter is assigned to a volume by MountMgr, the drive letter is reserved for the volume in the MountMgr database located in the system's registry.
		Drive letters for dynamic volumes are enumerated first and behave similar to importing foreign dynamic disks.
		For remaining dynamic partitions that cannot be assigned their suggested drive letter, they are assigned a letter based on the same rules as for basic disks.

		Your CD-ROM is not lost; it simply had its drive letter taken by a device with a higher priority.
		That is why the bootable floppy drive is A:, the non-bootable floppy drive is B:, the bootable primary partition on the first hard drive is C:, and the non-bootable primary partition on the slave ATA hard drive is D:.
		The displaced device will pick up the next available drive letter, and all associated drivers for the displaced device must be reconfigured.

	Problem with Drive letter assignment. - The PC Guide Discussion Forums
		Before replacing the third disk, the drive letter assignments were C, D, and E to primary partitions on disks 1, 2, and 3 respectively.
		One of the disks had Drive letter E assigned to the primary partition on the 20GB third disk, which is what I expected.
		Partition Magic 6.0 thinks that Drive letter E is always assigned to the primary partition on the third disk, disagreeing with the Windows 98SE assignments for two of the three disks.

	Re: Using /CLONE to restore the bootdrive in FAT16 ? [XARC 7918]
		The ability to assign a drive letter to a disk by the user is only with the NT-family Windows (which is done through entries in the system registry).
		There are other techniques that allows a program to inject a new drive letter by emulating a hard disk in which cases, the driveletter- assignment must follow the usual BIOS rule.
		The BIOS driveletter assignment scheme goes like this: When you boot a system into the DOS, the drive letter assignment was done by first-come-first-served basis C: first disk, first primary partition D: second disk, first primary partition E: third disk, first primary partition...

	FAQ Lost CD-ROM After Adding New Drive
		Drive letter assignment is dynamic, meaning DOS hands out its drive letters on-the-fly each time it boots.
		In a hypothetical system with two ATA (IDE) drives (the slave drive has two equal sized partitions), one SCSI hard drive, one CD-ROM drive, and a RAM drive, the logical drive letter assignments would be as follows:
		Since the CD-ROM device driver is loaded first, it gets the drive letter G:, and the RAM drive is assigned H:.

		The first primary partition on the first physical disk gets the drive letter C. Windows NT then checks all remaining disks for the first primary partition, and that is assigned a drive letter.
		After this process of lettering the first primary partition is completed for all physical disks, Windows NT then assigns drive letters to the logical drives in the extended partitions on each physical disk, starting with the first physical drive in the system.
		Finally, after all logical drives are assigned drive letters, all remaining primary partitions on all drives are assigned drive letters.

	Drive Letter Assignment Problem (Site not responding. Last check: 2007-11-04)
		We have noted an issue in which the NT operating system assigns a drive letter identical to the one that is already selected for use by the InveStore file system.
		When a new SCSI storage drive device (optical or other) is added to an existing server system, the NT operating system automatically assigns the next available drive letter to the drive following those of the existing server hard drive(s).
		During a restart, if the drives are Optical they are seen by the NT OS as removable hard drives and drive letters are assigned to each of them regardless of a previous assignment by any other programs, including InveStore.

		Regarding how Windows disk management and diskpart see the drives and allocate drive letters, this is not necessarily the same as how the drives are ordered in the BIOS and also does not seem to take into account which channel on the motherboard the drive is plugged into.

		Please note that the drive letters are assigned to partition entries in drives' partition tables, not to physical drives, and that this process is performed afresh each and every time the OS boots.
		Therefore a drive-letter assignment is not an inherent property of a given specific partition: Instead, what letter a partition receives at boot time depends on what other partitions the OS observes at that time, in the various physical drives' partition tables.
		On a given physical hard drive, you are limited to either 1-4 primary partitions or 0-3 primary partitions and an extended partition.

		After the tower has been installed, the internal CD-ROM drive may be automatically assigned to the next available drive letter after the tower.

		Drive letters will not be reassigned during your next boot up, so these letter choices will remain fixed until, or unless, you reassign them.
