I have a couple of 256GB PNY USB 3.0 sticks, less that a year old, which have had little use. One of them has been mounted in my laptop (Xubuntu 16.04, up to date) for about a week, with numerous read/writes. Suddenly, about an hour ago the laptop froze completely, no mouse, no keyboard. I had to use the power switch.
On rebooting I left the flash drive plugged in. When the boot process was complete I could not mount it, and then I noticed that its red 'activity' light was flashing rapidly. After a bit of poking around I pulled it out, then re-inserted it. This time the light was flashing continuously, although more slowly. I still could not mount or view it, although the computer saw it. >From the command line I found the problem, although it's strange. (Its label is '256GB-2.') $ cd /media/ /media$ cd jjj/ $ ls -la drwx------ 2 root root 4096 Sep 1 17:11 256GB-2 drwx------ 8 jjj jjj 4096 Mar 12 17:51 Data drwxr-xr-x 2847 jjj jjj 221184 Sep 1 16:12 Movies drwxr-xr-x 2788 jjj jjj 200704 Feb 9 2019 Synology jjj@Devil-Bonobo:/media/jjj$ cd 256GB-2/ bash: cd: 256GB-2/: Permission denied jjj@Devil-Bonobo:/media/jjj$ sudo cd 256GB-2/ sudo: cd: command not found I solved the problem with chown to retake ownership of the partition. But root can't use the cd command? And how come the partition became owned by root? _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
