solutions and ideas, methods and test-routines:
- the first idea i had was..:to move files off of the drive,
- the i thougt that it is a good idea to test the health of the drive
- benchmarking and checks of the dyn. performance: i.e. to test all of the sectors regarding the
situation of the individual sectors (i.e. if one is bad) - there are lots of intersting tools for that,
Well, in general, hard disks built-in health-check tool called SMART (Self-Monitoring, Analysis, and Reporting Technology), these do checks of the disk for potential problems. And they help to avoid loss of important data. generally SMART runs automatically; but you alos can do checks on your disk’s health by running the Disks application:
for a quick and easy test we can use smartctl; well this is pretty straightforward: we can check disk health on Linux by using the included smartctl utility on the terminal.
what is aimed:
- making sure that there is not any data corruption avoid to have issues.
- making sure that we do not have (or get) trouble in accessing the data on the hdd that means
- having troubles in accessing the files.
one test routine could be:
- Code: Select all
sudo smartctl -a /dev/sda | less
output: set of information about the hard drive's condition.
i like smartctl. It is running on my mx-system and it gives back a great overview.
by the way: there are some tests-methods - regarding the length & duration: short-test and long test..
The three different test are the following ones: Short, Long and Conveyance - with those you also see the time that it will take to complete all three test:
shorttest: a short test, usually sufficient at detecting issues: run it with:
- Code: Select all
sudo smartctl -t short /dev/sda: (run for the short test)
Longtest: a longer test if you are more concerned that examines the entire disk surface: s
- Code: Select all
udo smartctl -t long /dev/sda (for run this for the long test)
Conveyance: a conveyance test which is used to test if damages occurred during transportation of the device from the manufacturer:
- Code: Select all
sudo smartctl -t conveyance /dev/sda (run this for the conveyance test)
besides the command line, there are very popular and well known tool gnome-disk-utility
other tools:
- Palimpsest (aka gnome-disk-utility) GUI program that gives the same info;
- badblocks another utility; it shows the amount and location of bad blocks on the drive;
GUI-tools: For anyone who finds they don't have smartctl: it's probably under your package manager as "smartmontools".
badblocks is one more useful utility; this program shows the amount and besides this also the location of bad blocks on your drive:
- Code: Select all
sudo badblocks -v /dev/sda
see a demo output
- Code: Select all
