Hi all

There used to be about 30 MB of free HDD space out of the 61.4 MB, which was plenty for uploading a new firmeware for upgrade. Now something happened and the free HDD space is only 12 MB. Under Files there are only about 100 kB of data listed.
To free more HDD space I went to Stores / Disks and pressed the Clean Drive button and the message "All disk data will be lost! Clean anyway?" appeared. I pressed yes and the following error message appeared "Check Drive Error - cannot check/format system disk (6)".
How can I free some more HDD space?
Hardware: RB433AH with additional Micro-sd drive of 2 GB for proxy cash.
Firmeware: v3.27

What do you have in /file print and /system package print?

Hello Sergejs
Here are the requested data: Since submiting my post I upgraded to v4.2. The behaviour is as before.

I think you can download backup file, disk space for upgrade should be available after it.
Install 4.5 version and let us know about the results.

Thank you Sergejs.
One more question. When I press the Clean Drive button, the message "All disk data will be lost! Clean anyway?" appears. Does that mean that only the files which are not needed are removed, or does it also remove the firmeware, which would then require a new install?

I installed v4.5 in a spare board RB433AH and pressing the button Clean Drive shows the same error message as I described in my first post.

Thank you for the clean-drive report, it does not work in the way, like you can clear all unnecessary information.
You get the error, because router is not able to clear installed MikroTik RouterOS.

I have the same problem. I uninstall almost all packages but always see only 10.5MB free space. In file list there is nothing. How to remotely clean HDD?

Greetings,
Juraj.

If I am not mistaken, doing a netinstall should actually format the drive, therefore completly cleaning it.

Happy to ressurect an old post.
I enabled logging to disk to try and track down some issues.
Now the router's HDD is 'full' but I do not know how to clean it (remove old logs?).
All files deleted, but no space available: Any suggestions apart from backup/netinstall/restore?

EDIT:Does this mean all Mikrotik routers that log to something disk will eventually become unusable and have to be netinstalled?

Thanks

I'm also ran in this problem.
May be something changed and we can delete log files now?

Netinstall is the solution to clean the disc
