The \fIdevice\fR operand is the special 32 file corresponding to the device; for example, \fB/dev/dsk/c0d0p0\fR. The 33 \fInumber-of-sectors\fR operand is the number of blocks on the device. If 34 omitted, \fBmkntfs\fR automatically figures the file system size. 35 .SH OPTIONS 36 .sp 37 .LP 38 Supported options are listed below. Most options have both single-letter and 39 full-name forms. Multiple single-letter options that do not take an argument 40 can be combined. For example, \fB-fv\fR is the equivalent of \fB-f\fR \fB-v\fR. 41 A full-name option can be abbreviated to a unique prefix of its name. 42 .sp 43 .LP 44 Options are divided among basic, advanced, output, and help options, as listed 45 below. 46 .SS "Basic Options" 47 .sp 48 .ne 2 49 .na 50 \fB\fB-C\fR, \fB--enable-compression\fR\fR 51 .ad 52 .sp .6 53 .RS 4n 54 Enable compression on the volume. 55 .RE 56 57 .sp 58 .ne 2 59 .na 60 \fB\fB-f\fR, \fB--fast\fR or \fB-q\fR, \fB--quick\fR\fR 61 .ad 62 .sp .6 63 .RS 4n 64 Perform quick (fast) format. This option skips both zeroing of the volume and 65 bad sector checking. 66 .RE 67 68 .sp 69 .ne 2 70 .na 71 \fB\fB-L\fR, \fB--label\fR \fIstring\fR\fR 72 .ad 73 .sp .6 74 .RS 4n 75 Set the volume label for the filesystem to \fIstring\fR. 76 .RE 77 78 .sp 79 .ne 2 80 .na 81 \fB\fB-n\fR, \fB--no-action\fR\fR 82 .ad 83 .sp .6 84 .RS 4n 85 Causes \fBmkntfs\fR to not actually create a file system, but display what it 86 would do if it were to create a file system. All formatting steps are carried 87 out except the actual writing to the device. 88 .RE 89 90 .SS "Advanced Options" 91 .sp 92 .ne 2 93 .na 94 \fB\fB-c\fR, \fB--cluster-size\fR \fIbytes\fR\fR 95 .ad 96 .sp .6 97 .RS 4n 98 Specify the size of clusters in bytes. Valid cluster size values are powers of 99 two, with at least 256, and at most 65536, bytes per cluster. If omitted, 100 \fBmkntfs\fR uses 4096 bytes as the default cluster size. 101 .sp 102 Note that the default cluster size is set to be at least equal to the sector 103 size, as a cluster cannot be smaller than a sector. Also, note that values 104 greater than 4096 have the side effect that compression is disabled on the 105 volume. This is due to limitations in the NTFS compression algorithm used by 106 Windows. 107 .RE 108 109 .sp 110 .ne 2 111 .na 112 \fB\fB-F\fR, \fB--force\fR\fR 113 .ad 114 .sp .6 115 .RS 4n 116 Force \fBmkntfs\fR to run, even if the specified device is not a block special 117 device, or appears to be mounted. 118 .RE 119 120 .sp 121 .ne 2 122 .na 123 \fB\fB-H\fR, \fB--heads\fR \fInum\fR\fR 124 .ad 125 .sp .6 126 .RS 4n 127 Specify the number of heads. The maximum is 65535 (0xffff). If omitted, 128 \fBmkntfs\fR attempts to determine the number of heads automatically. If that 129 fails a default of 0 is used. Note that specifying \fInum\fR is required for 130 Windows to be able to boot from the created volume. 131 .RE 132 133 .sp 134 .ne 2 135 .na 136 \fB\fB-I\fR, \fB--no-indexing\fR\fR 137 .ad 138 .sp .6 139 .RS 4n 140 Disable content indexing on the volume. This option is only meaningful on 141 Windows 2000 and later. Windows NT 4.0 and earlier ignore this, as they do not 142 implement content indexing. 143 .RE 144 145 .sp 146 .ne 2 147 .na 148 \fB\fB-p\fR, \fB--partition-start\fR \fIsector\fR\fR 149 .ad 150 .sp .6 151 .RS 4n 152 Specify the partition start sector. The maximum is 4294967295 (2^32-1). If 153 omitted, \fBmkntfs\fR attempts to determine \fIsector\fRautomatically. If that 154 fails, a default of 0 is used. Note that specifying \fIsector\fR is required 155 for Windows to be able to boot from the created volume. 156 .RE 157 158 .sp 159 .ne 2 160 .na 161 \fB\fB-S\fR, \fB--sectors-per-track\fR \fInum\fR\fR 162 .ad 163 .sp .6 164 .RS 4n 165 Specify the number of sectors per track. The maximum is 65535 (0xffff). If 166 omitted, mkntfs attempts to determine the number of sectors-per-track 167 automatically and if that fails a default of 0 is used. Note that 168 sectors-per-track is required for Windows to be able to boot from the created 169 volume. 170 .RE 171 172 .sp 173 .ne 2 174 .na 175 \fB\fB-s\fR, \fB--sector-size\fR \fIbytes\fR\fR 176 .ad 177 .sp .6 178 .RS 4n 179 Specify the size of sectors in bytes. Valid sector size values are 256, 512, 180 1024, 2048, and 4096. If omitted, \fBmkntfs\fR attempts to determine the 181 sector-size automatically. If that fails, a default of 512 bytes per sector is 182 used. 183 .RE 184 185 .sp 186 .ne 2 187 .na 188 \fB\fB-T\fR, \fB--zero-time\fR\fR 189 .ad 190 .sp .6 191 .RS 4n 192 Fake the time to be 00:00:00 UTC, Jan 1, 1970, instead of the current system 193 time. This can be useful for debugging purposes. 194 .RE 195 196 .sp 197 .ne 2 198 .na 199 \fB\fB-z\fR, \fB--mft-zone-multiplier\fR \fInum\fR\fR 200 .ad 201 .sp .6 202 .RS 4n 203 Set the master file table (MFT) zone multiplier, which determines the size of 204 the MFT zone to use on the volume. The MFT zone is the area at the beginning of 205 the volume reserved for the MFT, which stores the on-disk inodes (MFT records). 206 It is noteworthy that small files are stored entirely within the inode; thus, 207 if you expect to use the volume for storing large numbers of very small files, 208 it is useful to set the zone multiplier to a higher value. Although the MFT 209 zone is resized on the fly as required during operation of the NTFS driver, 210 choosing an optimal value reduces fragmentation. Valid values are \fB1\fR, 211 \fB2\fR, \fB3\fR, and \fB4\fR. The values have the following meaning: 212 .sp 213 .in +2 214 .nf 215 MFT zone MFT zone size 216 multiplier (% of volume size) 217 1 12.5% (default) 218 2 25.0% 219 3 37.5% 220 4 50.0% 221 .fi 222 .in -2 223 .sp 224 225 .RE 226 227 .SS "Output Options" 228 .sp 229 .ne 2 230 .na 231 \fB\fB--debug\fR\fR 232 .ad 233 .sp .6 234 .RS 4n 235 Includes the verbose output from the \fB-v\fR option, as well as additional 236 output useful for debugging \fBmkntfs\fR. 237 .RE 238 239 .sp 240 .ne 2 241 .na 242 \fB\fB-q\fR, \fB--quiet\fR\fR 243 .ad 244 .sp .6 245 .RS 4n 246 Verbose execution.
