Check HDD status
Check HDD status
There are several tools to verify the condition in which there is a disc. One is the smartctl command. Smartctl is in the package smartmontools and is in the Debian repositories so its installation is simple: 
# aptitude install smartmontools For readability can be run as follows smartctl to check the status of a hard drive (sda in this case ):
# smartctl-a / dev / sda
Power_Cycle_Count indicates the number of times the hard drive has started
Power_On_Half_Minutes indicates the total time worked hard disk Reallocated_Sector_Ct indicates bad sectors
More information in your manual: # man smartctl
Repair damaged sectors
If some sectors are damaged can be repaired with the command badblocks:
# badblocks-s-v-n-f / dev/sdb1
parameters:-s
means that shows the scanning disc, displaying the fields and checked.
-v verbose mode-n puts us in a non-destructive, this means that if bad sectors to recover information on the hard disk will not be damaged or deleted.
-f repair the damaged sectors.
An alternative to HDD Regenerator badblocks is that although there is free software works well.
Monitor hard disk status Another tool called smart-notifier that sends a message when the hard disk is likely to fail. Even when the hard disk temperature changes and heat more than usual sends a message on screen. Installation is simple as all packages in Debian: # aptitude install smart-notifier
Once installed, it will run when you log into the graphical environment. To verify that you have to run in Gnome go to System menu
,
Preferences, Sessions . In the Startup Programs tab
will find the list of programs including "Smart Notifier." If that is not added and placed in command "smart-notifier".
Now we can verify that the smartmontools daemon running on system startup (easily done with the command rcconf).
