Hello!
I am running a full install of Mint Cinnamon 19.1 from an external 240 gb USB SSD on a Thinkpad X230. It was first installed on that external drive in Nov 2019 so it has been running for about 7 months. It had been working flawlessly up until about a month ago when it started acting quite flaky – random black screens, mouse issues, needing to be restarted or shut down to resume proper behavior, won’t go into suspend – things like that.
I posted this question over at the Mint forums and it was suggested that I check the disk with Smartmontools, but before I attempt that, I did have a few questions about checking an external disk and backup that I hoped you could answer.
Or is there another way to check for errors that might be used?
The laptop itself has Win 7 installed and so far that seems to be working fine, and I don’t want to do anything that might impact that while I troubleshoot the Mint install on the SSD.
I have not received any error messages, and so far, I can get it running if I restart, but it does revert back to the same behavior after a time. I can provide more specifics of the types of behavior I am seeing if that will help.
My questions – before I begin the checking, I think I should do a back up of the SSD. I have been creating Timeshifts – but they are (unfortunately) stored on the SSD, so they probably won’t do me any good if there is a drive issue. Is there a way to move those to a different drive, and would they then be useful if I needed to try to reinstall or recreate that drive?
I’ve been reading Ascaris’s Veeam Tutorial, and have a question about that. Would I need another external drive to create that kind of backup? Can I use a powered USB hub to attach both my Linux SSD and a separate drive for the backup? Would a large thumb drive be acceptable to use for this, and does it need to be formatted in a certain way? And if there are disk errors, would creating a backup be of any real use?
If I do find errors – is it possible that they can be fixed?
My other thought is that perhaps this strange behavior is really more of a software type issue. It “seems” that the black screen issue happens when I try to click on a FF window or Thunderbird mail. The computer seems to hesitate – like it is overloaded and waiting for something to finish running, and then just goes black. The drive and laptop are still both on – just can’t access the screen.
So, I do wonder whether there could be “something” running that might be causing the “pause” and not allowing the laptop to respond, but I don’t see anything in the power usage that would indicate something temporarily gobbling up resources and causing the lag, or lack of response. And I have 8GB RAM, and generally only use about 30-35% when running several programs at once. I’ve really never seen it over about 50%.
Also, I have noticed this behavior whether the SSD is plugged directly into the laptop’s USB 3.0 port, or plugged into a powered USB 3.0 hub.
In any case – I appreciate any ideas or help in checking the SSD and possible backup thoughts. And – maybe, suggestions on possible fixes if I do discover an issue with the SSD.
Thanks so much!
