Mageia forum

Hi All
Running KDE. Mageia 6. Plain vanilla. Recently when I plug in a USB drive it asks for the root password (to connect and disconnect) . USB sticks do not work but they did in the past, I have lots of them. I wonder if my motherboard is dying ( I always end up with the old ones, being the old techo :} I have played around trying different settings but no such luck so I could have made things worse. Portable Hard drives work Ok other than wanting the root password to connect and disconnect. Otherwise every thing is working fine. Any help most appreciated. Roy

Please do the following: open a terminal, and as root run:

Code: Select all

journalctl -af

then wait a few seconds, and plugin one of the non-working USB sticks, and wait again fifteen seconds or so, until no new output appears.
Then post everything here.

Ok for a flash drive

Code: Select all

Seems either that stick is not partitioned, or the NTFS filesystem needs a chkdsk run.

Please show your /etc/fstab and also the output of

Code: Select all

lsblk -fl
fdisk -l

once that same usb drive is plugged in.

Hi doktor
Thank you for your help and support over the years.
You helped to find several causes of the problems. Some drives needed reformatting (the biggest problem) some drives are just dead now as they will not format. USB extension lead from back of PC to front is failing so that is gone now and replaced with a new one.
So all is good now.
Cheers Roy

They may need to have the partition table wiped/recreated, and new partition created, before formatting.
Helped my father with that recently, when his MSW10 failed to format a micro SD.
I used gparted on Mageia.
