Dolphin question SOLVED

[Old-Polack]

Where is the evidence of errors in the fat32 filesystem? I see a lot of assumptions, but no real evidence.

dougmack:

Before resorting to such drastic measures as repartitioning, etc., open a terminal, su to root, then, with the USB drive plugged in, enter the following commands;

To be sure the USB drive is not mounted;

[root@localhost ~]# umount -a                       <Enter>

To check if the USB drive is still seen as /dev/sdd;

[root@localhost ~]# fdisk -l                             <Enter>

To check and fix the fat32 filesystem, assuming it still shows as /dev/sdd1;

[root@localhost ~]# dosfsck -a /dev/sdd1                        <Enter>

Post your results.

did i ever said evidence?  i had those problems in the past and i said what i would do in that case

you want answers but we don't have to see you get them this way, you don't have to come and make me look bad every time, i can do that without your help

I did not try lsof or fuser until after I had done the above, but the results were not helpful:

[root@Linux1 doug]# lsof
bash: lsof: command not found
[root@Linux1 doug]# fuser
No process specification given
Usage: fuser [ -fuv ] [ -a | -s ] [ -4 | -6 ] [ -c | -m | -n SPACE ] [ -k [ -i ] [ -SIGNAL ]] NAME...
       fuser -l
       fuser -V
And so on with the help routine.
Found that lsof was not installed, so I installed it and ran it.  I got a *huge* output that looks like a history of everything I have done on the machine for days!
I really doubt that you would want me to post that here.

You didn't need the lsof, and the output is irrelevant for our purposes. The important thing was to run dosfsck on /dev/sdd1 to see if any corruption was reported. Obviously it was not, so you should be good to go with the USB stick as is. 

[dougmack]

Thanx, OP.  I think that finally puts a close to this thread.  I'll probably never know why it gave me grief at first, but it seems to work OK now.
