Windows NT tends to follow the drive lettering conventions established
years ago for the earliest hard drives. However, Windows NT has fewer
restrictions on the number of hard drives it supports. For example, most
systems do not support more than two hard drives in the BIOS, with the
remainder being supported by drivers loaded in CONFIG.SYS. Thus, the
same partitions may have different letters in a system such as MS-DOS and
Windows NT. Please note that this article discusses only the default drive
lettering; you can use sticky drive letters (Disk Administrator) to alter this
lettering.
In this article, primary partition refers to any partition that is a recognized
partition (the different FAT partition types [1, 4, and 6], HPFS [High
Performance File System] and NTFS [NT File System] [7]). A non-
extended partition refers to a partition that has a type other than 0 (Empty)
or 5 (Extended).
More Information:
This article describes the rules that Windows NT follows when assigning
drive letters. Note: Only recognized partition types (1, 4, 6, 7) are assigned
drive letters.
If there is a primary partition on the first hard drive marked as active, it gets
the first drive letter (C); otherwise, the first drive letter is assigned to the first
recognized primary partition.
This process is repeated for all hard drives in the system. Please note that if
you have multiple controllers in your system, the drive letter ordering is
based on the order in which the device drivers are loaded by Windows NT.
Once the letters have been assigned to the first primary partitions on all
drives in the system, letters are assigned to the recognized logical disks in the
extended partitions using the same scheme as outlined above, starting with
the first drive in the system.
After all of the logical disks in the extended partitions are assigned letters,
one last scan is made of the drives, and letters are assigned to any remaining
recognized primary partitions.
For drives referenced in BOOT.INI, the ordering is similar except that the
above scan is done only for drives supported in the BIOS. For drives not
supported in the BIOS, it is necessary to use the arcname style paths. The
most applicable arcname naming conventions are:
multi()disk()rdisk()partition()\...
scsi()disk()rdisk()partition()\...
The two are similar, except that the multi()disk() format varies the rdisk()
parameter for successive disks on one controller (with a limit of two per
controller), whereas the scsi()disk() notation uses the disk() parameter.
Note that the rdisk() parameter actually refers to which SCSI logical unit
(LUN) to use, which could be a separate disk, but the vast majority of
SCSI setups have only one LUN per SCSI ID.
The partition() portion of the arcname refers to the partition number.
Partition numbers are assigned, starting with partition(1). Note that
partition(0) refers to the entire disk. First, all non-extended partitions (those
having a partition type other than 0 or 5) are assigned numbers (and the
active bit does not play a role), and then all logical drives in extended
partitions are assigned numbers.
For example:
Assume a system with two controllers, one a WD1003 compliant controller
(IDE/ESDI/ST506) supported by the ATDISK driver, and the other a
SCSI host adapter supported by a SCSI miniport driver. There are two
drives attached to the ATDISK controller and one drive attached to the
SCSI host adapter (at SCSI ID 0).
There are two primary partitions on the first ATDISK drive, two partitions
(one extended partition with one FAT partition inside and one primary
NTFS partition) on the second ATDISK drive, and one primary FAT
partition on the SCSI drive.
+---------------+-----------------+
1/2| Primary (FAT) | Primary (XENIX) |
+---------------+-----------------+
+--------------------------+----------------+
3/4|Extended (one FAT inside) | Primary (NTFS) |
+--------------------------+----------------+
+--------------+
5 |Primary (FAT) |
+--------------+
The drive letters are assigned as follows:
MS-DOS: C=1, D=3, E=5 (loaded in CONFIG.SYS); 2 and 4
do not have
drive letters.
Windows NT: C=1, D=4, E=5, F=3; 2 does not have a
drive letter.
NTLDR/BOOT.INI: C=1, D=4, E=3; 2 and 5 do not have
drive letters.
The arcname for each of the partitions is:
1: multi(0)disk(0)rdisk(0)partition(1)
2: multi(0)disk(0)rdisk(0)partition(2)
3: multi(0)disk(0)rdisk(1)partition(2)
4: multi(0)disk(0)rdisk(1)partition(1)
5: scsi(0)disk(0)rdisk(0)partition(1)
