11 | .SH NAME |
| 12 | hd \- MFM/IDE hard disk devices | |
| 13 | .SH DESCRIPTION | |
| 35cfd378 MK |
14 | The |
| 15 | .B hd* | |
| 16 | devices are block devices to access MFM/IDE hard disk drives | |
| c13182ef MK |
17 | in raw mode. |
| 18 | The master drive on the primary IDE controller (major device | |
| 35cfd378 MK |
19 | number 3) is |
| 20 | .BR hda ; | |
| 21 | the slave drive is | |
| 22 | .BR hdb . | |
| c13182ef | 23 | The master drive of the second controller (major device number 22) |
| 51700fd7 | 24 | is |
| 35cfd378 | 25 | .B hdc |
| 66fbc196 | 26 | and the slave is |
| 35cfd378 | 27 | .BR hdd . |
| c6d039a3 | 28 | .P |
| fea681da MK |
29 | General IDE block device names have the form |
| 30 | .BI hd X\c | |
| 31 | , or | |
| 32 | .BI hd XP\c | |
| 33 | , where | |
| 34 | .I X | |
| 35 | is a letter denoting the physical drive, and | |
| 36 | .I P | |
| 37 | is a number denoting the partition on that physical drive. | |
| 38 | The first form, | |
| 9ebe66fa MK |
39 | .BI hd X\c |
| 40 | , is used to address the whole drive. | |
| fea681da | 41 | Partition numbers are assigned in the order the partitions |
| 24b74457 | 42 | are discovered, and only nonempty, nonextended partitions |
| c13182ef | 43 | get a number. |
| 523869f6 | 44 | However, partition numbers 1\[en]4 are given to the |
| 84c517a4 | 45 | four partitions described in the MBR (the "primary" partitions), |
| fea681da MK |
46 | regardless of whether they are unused or extended. |
| 47 | Thus, the first logical partition will be | |
| 48 | .BI hd X 5\c | |
| 49 | \&. | |
| 50 | Both DOS-type partitioning and BSD-disklabel partitioning are supported. | |
| 51 | You can have at most 63 partitions on an IDE disk. | |
| c6d039a3 | 52 | .P |
| fea681da | 53 | For example, |
| 8478ee02 | 54 | .I /dev/hda |
| fea681da | 55 | refers to all of the first IDE drive in the system; and |
| 8478ee02 | 56 | .I /dev/hdb3 |
| 84c517a4 | 57 | refers to the third DOS "primary" partition on the second one. |
| c6d039a3 | 58 | .P |
