Some slow down the self-test even on average system load such that the test virtually never ends. This also aborts any running self-test. The self-test log then reports Aborted by host or Interrupted host reset as status. This is typical for drives behind USB bridges. As a workaround, run some tool or script which perform periodic low volume read accesses. These utilities have an important role to fill. If your disk has bad sectors for example, as revealed by running self-tests with smartmontools and the disk is not able to recover the data from those sectors, then the disk will not automatically reallocate those damaged sectors from its set of spare sectors, because forcing the reallocation to take place may entail some loss of data.
Because the commands that force such reallocation are Vendor Specific , most manufacturers provide a utility for this purpose.
It may cause data loss but can repair damaged sectors at least, until it runs out of replacement sectors. The check cannot be disabled in this case. Yes and no. Smartctl and smartd run on a virtual machine guest OS without problems. If a guest OS disk is configured as a raw disk, this only means that its sectors are mapped transparently to the underlying physical disk. Even the disk's identity is typically not exposed to the guest OS. The file smartctl-nc.
This prevents that an empty console window is opened when the command is run in background with output redirected. GSmartControl uses this command for this purpose. When smartctl-nc is run without redirection from a console window, its output is not visible because Windows detaches the program from the console.
This is usually the case for drivers which support RAID. The message does not indicate a hard disk problem'' It does also not mean that the disk itself does not support SMART logs. These calls were available since Win95 OSR2. An example program from Microsoft can be found SmartApp? Starting with NT4, these calls do more restrictive parameter checks. Unfortunately, these undocumented functions are not implemented in most vendor specific ATA device drivers.
It should be supported by most new drivers. Experimental code using this call was added and is included in smartmontools release 5. The log messages appear because your system doesn't have most of these devices. It is possible to use Linux LiveCD to get full information about the drive. Mac OS X does not support diagnosing external drives using S.
In order to allow your Mac to diagnose external drives, you will need to install a special third party driver. Please note that this is a requirement of Mac OS X, and not smartmontools. This is found on USB 3. Firmware may fix this error. The ATA error log is stored in a circular buffer, and the ATA specifications are unambiguous about how the entries should be ordered.
This warning message means that the disk's firmware does not strictly obey the ATA specification regarding the ordering of the error log entries in the circular buffer. Smartmontools will correct for this oversight, so this warning message can be safely ignored by users.
On the other hand, firmware engineers: please read the ATA specs more closely then fix your code! Yes there are. Since the smartmontools utilities run as root, you might be concerned about something harmful being embedded within them.
Starting with release 5. The fingerprint are given in a file on the release page with a name like smartmontools From Maxtor disks 99 , , and They will be used in SMART revision 6, but the engineering group has not yet decided what to monitor with these Attributes. The LBAs to be scanned are specified in the following formats:.
Before performing a test, an approximate indication of the time duration of the various tests are displayed using the following command:. It is also possible to perform an "offline" test. Views View View source History. Personal tools Create account Log in. From Thomas-Krenn-Wiki.
Extended self-test routine recommended polling time: 83 minutes. Conveyance self-test routine recommended polling time: 5 minutes. Testing has begun. Then there's "-m root". What is root's email address? How does root receive the messages? How does root read the messages? Must they be sent to root? I find man pages are frequently unhelpful. They seem to be written by experts for the consultation of other experts.
The jargon is mostly impenetrable and useful explanations are scarce. Your use of English is sometimes confusing. If I could understand what you are trying to say, I could help you rewrite it. Is there a way to eliminate the check on a USB drive? Every ten minutes I get data added to the output of 'dmesg' which I'm not sure is valid. It overloads the 'dmesg' information and makes it hard to see anything else. Can some one help me with this issue? We have a storage that has disks.
To check the detailed info on each disk, we enter the following command:. Is it possible to have one command to check ALL of the disks with a single command, like using a wildcard or something? Thank you very much for this article. I am very happy that I've learned a bit more about smartctl and my disks. This how to will help you to configure Smartmontools to do actions such as shut down the computer or send an e-mail when the disk is going to fail.
Prerequisites A modern S. This will give you brief information about your drive. It's a nice graphical frontend to smartctl; it shows all SMART values, and highlights those that indicate old age or impending failure, plus you may run tests on demand: As usual, you may install it from Synaptic or running sudo apt-get install gsmartcontrol.
Again, use your favourite text editor to open this file. There are several -M directives that change when and how often reports are sent. You need to specify -m something in order to use them, even if you're not sending any mail.
