I have tested your issue on latest FF release v50.0 and latest Nightly build (Build ID: 20161123030208)and could not reproduce it. I have connected an USB Drive dock from Icy Box to the PC and as for HDD I've used an Wested Digital Blue 250GB. I have accessed various websites and use debugger on them and inspected multiple elements from the page. During this time the HDD was not used.

Can you provide a more accurate test case or steps? Please provide also the webpage on which this issue has been encountered. 

Can you please retest this using latest Nightly build (https://nightly.mozilla.org/) and report back the results ? When doing this, please use a new clean Firefox profile, maybe even safe mode, to eliminate custom settings as a possible cause (https://goo.gl/PNe90E). Please do this also for the release Firefox version.

then I don't know where the problem stems from. it doesn't seem to be doing it on my side now. strange. it looked quite reproducible.
I don't know what the underlying Windows OS (XP media center edition 2005) is doing.
if I use nightly, I can't use production stable anymore. and I do a lot of debugging and development of production code with it.
I cannot supply the code, it is part of a semi-commercial library.

just close this bug. after upgrading to 50.1 it seems to have gone away. so it looks fixed.

tip: if you are using the drive with NTFS, make sure you power off the drive after the machine is off, unless you are in hibernation then do not power it off. take it out of hibernation (resume), and the shutdown the machine. after computer has powered off, then it is safe to power off the drive. if computer is in hibernation and the list of drives changes, you can lose a filesystem completely without a way to get it back. I even tried recovery utilities. besides, it's nicer on the unit's power supply.
