Hi all, I recently bought a 1TB Seagate Expansion Portable HDD (model number: SRD00F1). It works fine on my Windows 7 laptop.

On my Linux desktop, however, I can read from the HDD, but I cannot delete files on it or write to it. When I try to copy a file to the HDD, I get the following error from Dolphin File Manager: "Access denied. Could not write to '/run/media/divan/device_name"

What I've tried so far, in chronological order, but with success:
1. chmod 777 /dev/sdb (I made sure the HDD WAS /dev/sdb by checking gparted)
2. formatting the drive on Windows 7 to ntfs.
3. formatting it on my Linux desktop(the same) to ext4.
4. formatting it to ntfs in my Linux desktop(the same).

Also, I did the same with another external hard drive(LG HXD5 500GB) and got exactly the same error.

My desktop's details are:
3.13.7-1-ARCH Linux running KDE Version 4.12.3

Just as a side note, the way my desktop is handling the HDD's seems suspiciously allot like it would read a ROM like a CD or DVD. Maybe that has some relevance, but it's pure speculation.

Thank you for reading!

Have you looked at the wiki?
https://wiki.archlinux.org/index.php...torage_Devices

drives are normally auto mounted as READ ONLY for non root users

this can be set in the /etc/fstab file

it is NEVER!!!! a wise idea to run "chmod 777" on anything

the only way a linux OS can read and write to a Microsoft (patented) NTFS file system is if "NTFS-3g" is installed

Arch linux will auto mount a MICROSOFT NTFS formatted drive as "read ONLY "
-- by default--
