Lately for whatever reason my computer has been freezing up when I am in the terminal. I have two partitions, one for my home folder which is sittin on an SSD and a second one for my bulk storage which is my HDD. I have the HDD mounted on
/run/media/user/DATA/
and after using the laptop for (we'll say a little while I've not yet noticed what is causing this....) whenever I try doing anything inside the
/run/medai/user/DATA/
folder the terminal will freeze up and be unusable. for example somthing like
cd /run/media/user/DATA (tab to autocomplete)
will leave the terminal hanging or
sudo umount /run/media/user/DATA
does the same, where as something like
ls /etc/netctl/A (tab to autocomplete)
works just fine. I'm not really sure what information would be needed to debug this so please let me know and I will post it! Also whenever trying to access the partion in Dolphin, Dolphin will freeze up as well becoming unusable. (Also not sure if it's important to note but it is independent of the command that I use it is just whenever I attempt to access the bulk partition)

Have a look at dmesg messages. Run
dmesg -w
in another terminal and look for anything suspicious when the freeze occurs. Same with
journalctl -f
(systemd logs).

this is the output of dmesg -w when the freeze happens

Something wonky is happening in kernel space.
Maybe run fsck on the HDD, to make sure it is not a hardware problem.
You could try upgrading your kernel, also.
EDIT : It seems like this kernel warning happens when a process has been waiting too long for IO. In your case, it could be that another process is hogging the HDD.
Run iotop and look for anything suspicious.

The drive isn't responding. How is it attached USB?
Could be an USB autosuspend issue: https://wiki.archlinux.org/index.php/Po … utosuspend
This might also be controlled by some power management daemon.

it's an internal HDD (so I'm assuming a sata cable? not entirely sure if laptops are built similarly to a desktop sorry ) and I haven't done/changed anything in my power management setttings... also I'm not sure if it's relavent but now when pressing Ctrl+Alt+T to open a console journalctl -f displays the following message

Looks like you ran an update and didn't reboot. This can cause trouble with dlopen'd libraries (aka "plugins")
There're usually no SATA cables in notebooks ;-)
See whether the disk responds to hdparm (whether it's in standby and whether you can wake it) and check it's condition and run a health test.

Health test result: PASSED can mean the device is perfectly fine, or the device is technically dead but has not yet officially acknowledged that it is. Look at/post smartctl -a for a more relevant judgement, also make sure that you wait out the allotted time the long test mentions before calling -a as that may cause the test to be interrupted.

Where does the article say "vim"?
That "file" is actually a kernel variable, if you want to invoke sudo to write into it, the general "trick" is to invoke tee (a T-pipe)
echo cfq | sudo tee /sys/block/sda/queue/scheduler
Offline
that was my bad!! I guess I just assumed it was a regular old file rather than a kernel variable. It's now updated though so we'll see I guess!

Ok, so it's not the scheduler, the disk looks healthy and on a notebook it's most likely not the connection either.
Does it also happen with the main kernel, https://www.archlinux.org/packages/core/x86_64/linux/ ?
