Usage: sg_read_long [--16] [--correct] [--help] [--lba=LBA] [--out=OF]
[--pblock] [--readonly] [--verbose] [--version]
[--xfer_len=BTL] DEVICE
where:
--16|-S do READ LONG(16) (default: READ LONG(10))
--correct|-c use ECC to correct data (default: don't)
--help|-h print out usage message
--lba=LBA|-l LBA logical block address (default: 0)
--out=OF|-o OF output in binary to file named OF
--pblock|-p fetch physical block containing LBA
--readonly|-r open DEVICE read-only (def: open it read-write)
--verbose|-v increase verbosity
--version|-V print version string and exit
--xfer_len=BTL|-x BTL byte transfer length (< 10000) default 520
Perform a SCSI READ LONG (10 or 16) command. Reads a single block with
associated ECC data. The user data could be encoded or encrypted.
Options (10)
| Option | Description | Source |
|---|
--lba, -l LBA|-l | where LBA is the logical block address of the sector to read. | help + man |
--out, -o OF|-o | instead of outputting ASCII hex to stdout, send it in binary to the file called OF. | help + man |
--xfer_len, -x BTL|-x | where BTL is the byte transfer length (default to 520). | help + man |
-S, --16 | uses a SCSI READ LONG(16) command. (in the manual page but not in --help) | man |
-c, --correct | sets the 'CORRCT' bit in the SCSI READ LONG command. (in the manual page but not in --help) | man |
-h, --help | output the usage message then exit. (in the manual page but not in --help) | man |
-p, --pblock | sets the 'PBLOCK' bit in the SCSI READ LONG command. (in the manual page but not in --help) | man |
-r, --readonly | opens the DEVICE read-only rather than read-write which is the default. (in the manual page but not in --help) | man |
-v, --verbose | increase the level of verbosity, (i.e. debug output). (in the manual page but not in --help) | man |
-V, --version | print the version string and then exit. (in the manual page but not in --help) | man |
