that it is predicting its own failure within the next 24 hours. If

+
+[ATA] Health status is obtained by checking the (boolean) result returned
+by the SMART RETURN STATUS command.
+The return value of this ATA command may be unknown due to limitations or
+bugs in some layer (e.g. RAID controller or USB bridge firmware) between
+disk and operating system.
+In this case, \fBsmartctl\fP prints a warning and checks whether any
+Prefailure SMART Attribute value is less than or equal to its threshold
+(see \'\-A\' below).
+
+[SCSI] Health status is obtained by checking the Additional Sense Code
+(ASC) and Additional Sense Code Qualifier (ASCQ) from Informal Exceptions
+(IE) log page (if supported) and/or from SCSI sense data.
+
+[SCSI tape drive or changer] TapeAlert status is obtained by reading the
+TapeAlert log page.
+Please note that the TapeAlert log page flags are cleared for the initiator
+when the page is read.

For example the commands:
.nf
- smartctl \-t select,10\-20 /dev/hda
- smartctl \-t select,10+11 /dev/hda
+ smartctl \-t select,10\-20 /dev/sda
+ smartctl \-t select,10+11 /dev/sda
.fi
both runs a self test on one span consisting of LBAs ten to twenty
(inclusive). The command:
.nf
- smartctl \-t select,100000000\-max /dev/hda
+ smartctl \-t select,100000000\-max /dev/sda
.fi
run a self test from LBA 100000000 up to the end of the disk.
The \'\-t\' option can be given up to five times, to test
up to five spans. For example the command:
.nf
- smartctl \-t select,0\-100 \-t select,1000\-2000 /dev/hda
+ smartctl \-t select,0\-100 \-t select,1000\-2000 /dev/sda
.fi
runs a self test on two spans. The first span consists of 101 LBAs
and the second span consists of 1001 LBAs. Note that the spans can
overlap partially or completely, for example:
.nf
- smartctl \-t select,0\-10 \-t select,5\-15 \-t select,10\-20 /dev/hda
+ smartctl \-t select,0\-10 \-t select,5\-15 \-t select,10\-20 /dev/sda
.fi
The results of the selective self-test can be obtained (both during
and after the test) by printing the SMART self-test log, using the

.nf
- smartctl \-t select,10\-20 /dev/hda
- smartctl \-t select,redo /dev/hda
- smartctl \-t select,redo+20 /dev/hda
+ smartctl \-t select,10\-20 /dev/sda
