NAME
       hddtemp - Utility to monitor hard drive temperature

SYNOPSIS
       hddtemp [options] [type:]disk...

DESCRIPTION
       hddtemp  will  give  you  the  temperature  of  your hard drive by reading Self-Monitoring Analysis and
       Reporting Technology (S.M.A.R.T.)  information on drives that support this feature.  Only  modern  hard
       drives  have  a  temperature sensor.  hddtemp supports reading S.M.A.R.T.  information from SCSI drives
       too.  hddtemp can work as simple command line tool or as a daemon.

       You can specify one or more device drive path, where each path can be prefixed with a type  like  PATA,
       SATA or SCSI to force hddtemp too use one of these type (because detection can fail).

OPTIONS
       The  program  follows  the  usual  GNU  command line syntax, with long options starting with two dashes
       (`-').  A summary of options is included below.

       -b, --drivebase
              Display the database file that allows hddtemp to recognize a supported drive.

       -D, --debug
              Display various S.M.A.R.T. fields and their values.  Useful for finding a value  that  seems  to
              match the temperature and/or to send a report.  (done for every drive supplied)

       -d, --daemon
              Execute hddtemp in TCP/IP daemon mode (port 7634 by default).

       -f, --file=file
              Specify the database file to use.

       -F, --foreground
              Don't fork into the background even in daemon mode.  This is useful when running under a process
              supervisor.

       -l, --listen=addr
              Listen on a specific address.  addr is a string containing a host name or a numeric host address
              string.   The  numeric  host  address  string  is  a  dotted-decimal IPv4 address or an IPv6 hex
              address.

       -n, --numeric
              Print only the temperature (without the unit).

       -p, --port=#
              Port number to listen to (in TCP/IP daemon mode).

       -s, --separator=char
              Separator to use between fields (in TCP/IP daemon mode).  The default separator is `|'.

       -S, --syslog=s
              Switch to daemon mode and log temperatures to syslog every s seconds.

       -q, --quiet
              Don't check if the drive is supported.

       -u, --unit=C|F
              Force output temperature either in Celsius or Fahrenheit.

       -v, --version
              Display hddtemp version number.

       -w, --wake-up
              Wake-up the drive if needed (ATA drives only).

       -4     Listen on IPv4 sockets only.

       -6     Listen on IPv6 sockets only.

DRIVE DATABASE
       If you know your drive has a temperature sensor but it is being reported  unsupported,  tell  me  which
       model  and  which  manufacturer  it  is,  and/or just add a new entry in /etc/hddtemp.db.  Each line of
       hddtemp.db is either a comment, a blank line or a line containing:

       - a regular expression that allow hddtemp to recognize a drive or a
              set of drives from its model name or from a generic model name,

       - a value (ATTRIBUTE_ID from S.M.A.R.T.),

       - a C or an F to set the unit to Celsius or Fahrenheit,

       - a description.

       Feedback is welcome (see the REPORT section below).

TCP/IP DAEMON MODE
       Example of type forcing:

       # hddtemp SATA:/dev/sda PATA:/dev/hda

       To test hddtemp in daemon mode, start it like this:

       # hddtemp -d /dev/hd[abcd]

       and use telnet or netcat (which is known as nc on some systems) to get a reply:

       # netcat localhost 7634

       The drive database is read only once at startup, so hddtemp  must  be  restarted  if  the  database  is
       updated for the changes to take effect.

REPORT
       As  I  receive  a  lot  of reports, things must be clarified.  When running hddtemp with debug options,
       hddtemp will show sort of a dump of S.M.A.R.T. data.  Each field corresponds to an  information  field.
       The  standard  field  for  drive temperature is 194.  But this is not always the case (mostly for older
       drives).  Even if your drive has S.M.A.R.T. capabilities, it  doesn't  necessarily  mean  that  it  can
       report its temperature.  So, things must be determined through experimentation.

       So, you can try to guess which field by is the good one by running hddtemp at regular intervals:

        - just after starting up your PC/server/station,

        - after opening a window (a physical window🙂,

        - after opening the case,

        - whatever you can think of...

       and  looking  for  a field's value that would increase or decrease depending on what effect you want to
       induce.  Be careful, fields 4, 9, and 12 are often reported to match a temperature field but after some
       investigation  they  do  not.  But fields 194 (which is the standard field for temperature) and 231 are
       good candidates.

       Then, you can send me a report with outputs from `hddtemp --debug ...', `smartctl' or `hdparm -i  ...',
       and/or add an entry in hddtemp.db yourself.

BUGS
       If  hddtemp  crashes  (yes,  it  might)  for  some unknown reasons, look for a file named hddtemp.back‐
       trace.<PID>.XXXXXX (where XXXXXX is a random number generated at runtime) in /tmp.  Then, you can  then
       send  me  this file and the hddtemp binary.  The backtrace functionality is currently supported on i386
       architectures only.

SEE ALSO
       smartctl(8), syslog(3), syslogd(8).
