You have very different HFS+ error messages. It looks like that you have I/O errors after trying to generate the read/write requests. I assume that your syslog contains such error messages too. And I think that it is the primary reason of the issue. My last SSD drive worked well one year only. Now I can read from partitions on device but any write operations fail. So, sometimes a SSD drive can behave itself in very tricky way. > > > Are you sure that your SSD is alive (if partition lives on SSD)? > > I do not know what means "alive".

You can use smartmontools (for example, smartctl utility). But, frankly speaking, I think that it needs to treat a file system behavior in wise way for understanding a drive healthiness very frequently. If a file system emits error messages in a really crazy way then the most probable reason of an issue can be a drive itself. > > > > If you'll move partition on another device the issue will be > > reproducible? > > How can I move a partition? > You can use different specialized tools. I think you can use Gparted, dd, rsync or cpio utilities under Linux. I think you can find the description of using with tools for moving a partition in the Internet. > Would it help if I create a partition of the same type on a USB drive, > and see if I get similar errors? > > I just have another SSD, is it ok? > Or should I try to get a USB HDD? > It is possible to use any valid device. But HDD sounds as more reliable way for me. But, finally, it's up to you.
