Do you have to be in root to make this work? Does the same command work for Mac? This was really helpful thanks

I ran badblocks without the -b option. Would that still work and give me accurate results? I had no idea.

[skrach]

Thanks for the video. Could make a video of what to do if one finds badblocks (please). My situation is that I found some and the issue is that at the moment I can't write a partition table (yet). So if you have any suggestion it will be helpful. Greetings

You say that I can use command "ssm list dev" then you tell me that that "ssm" stands for "system storage manager", very good!
But when you say that you can always use command "fdisk -l", you did not say what "f" or "l" stands for? :(

[freefallingearth]

Using Ubuntu on windows and it can't see my HDD connected. it also says ssm not found, when inputted. fdisk -l doesn't list my HDD that was formated to ext4 on a NAS, my God, takes all day just to check bad sectors on an old 3TB hard drive and still no success from these videos
