![]() Don't forget to have that bin folder to be added to your path. Next, placed it in my /home/user/bin folder, chmod +x /home/user/bin/remove-usb.sh. A sudden loss of power can cause many different kinds of failure in a hard disk drive. There is no well-known way to 'reset' them. Just plug power in, turn it on, and SMART starts watching and logging to it's own NV registers. The values are generated and accumulated in the hard drive itself. Udisks -unmount /dev/$(echo $DEVICE)1 & udisks -detach /dev/$DEVICE SMART is a firmware feature on hard drive, not any operating system or software. Here it is: #!/bin/shĭEVICE=$( udisksctl status | grep -i sandisk | xargs echo | cut -d' ' -f6 ) Next, I've put together the script remove-usb.sh. Of course for you, you'd have to use udisksctl status | grep -i wd | xargs echo and count which element is your block id is, and then use appropriate number on cut -d' ' -fx Here we can use cut command to extract it like so: udisksctl status | grep -i sandisk | xargs echo | cut -d' ' -f6 What would be the output of this command : udisksctl status | grep -i sandisk | xargs echo ? It would be this: SanDisk Cruzer Glide 1.27 2005425573077FA0AA67 sdd, or in other words information about the usb, delimited by spaces, with the device id being last argument, or the 6th one. We'd need to let the shell know the block id of out external hdd or usb. However, at 45,000 hours of use I would be backing up your critical files and expecting drive failure sooner rather than later. What if we could write a script to do the safe-ejecting for us ? This will tell you if there are any slow or unresponsive sectors on the disk surface, which are a far more accurate predictor of drive failure than the disk temperature.

I have one drive currently with a power on count of 2,401 and 36,615 hours that is fine and another that has a power on count of 95 and 17,442 total hours that has failed. Now, here's something I've done purely for fun, but you could find it useful and adapt to your own needs. Unfortunately powering on and off a drive does not wear it out faster or slower. TIP: you can use udisksctl status | grep -i wd to show only information for the external hard drive. With the one-liner I use, I've noticed that the device id is preserved, i.e, if i eject the usd and reconnect it, it still gives the device sdc name. So in my case, I would eject the usb with udisks -unmount /dev/sdc1 & udisks -detach /dev/sdc or alternatively with what Fabby suggested. Each time you pugin a usb device it will be identified with different letters, sdb, sdc,sdf and so forth, while sda is always your hard-drive. The output of the commands is the following:Īs you can see both report that my usb drive is identified as /dev/sdc. For instance, I have a Sandisk Cruiser usb drive connected right now. ![]() You can use lsblk and identify it by mount-point and size on the other hand, you can use udisksctl status. Basically, i use udisks -unmount /dev/sdb1 & udisks -detach /dev/sdb where sdb1 is the mount-point and sdb is the actual disk. I have answered related question some time ago, when just started out with ubuntu, so I suggest you refer to it as well. Then you can use either udisks or udisksctl to unmount and actually power off the device. If it's not, continue with the steps below.So far I haven't found a simple alternative to "safely eject" in the file manager, so this is my justification for using command line here.įirst, you'd need to find out your external hard-drives device id or block id. Under the "The following states are available on this system" section, if Hibernate appears, then the feature is enabled.Type the following command to confirm the hibernation status and press Enter: powercfg /availablesleepstates.4 Once a drive has surpassed the 43,800 hour mark, it may no longer be classed as in 'perfect condition'. Search for Command Prompt, right-click the top result, and select the Run as administrator option. Power-on hours is intended to indicate a remaining lifetime prediction for hard drives and solid state drives, generally, 'the total expected life-time of a hard disk is 5 years' 3 or 43,800 hours of constant use. ![]() To check and enable hibernation on Windows 11, use these steps: When using hibernation, the resume process is slower than sleep, but it helps you conserve more battery. The feature works by saving the data in memory onto the hard drive, allowing you completely shut down and resume where you left off without wasting power. On Windows 11, hibernation is a feature that can help preserve battery life when you are not using the device.
