I'm running Electrum 2.9.0 on Linux Mint 18.2

I came to the realisation that if I lose my phone, I will have to recreate my wallet using the method described in:
http://docs.electrum.org/en/latest/2fa.html
using the "Restoring from seed" and selecting the "wallet with 2FA"

As this has been described a number of times on this forum (see here for the last one I read on how to restore your wallet with LOST 2FA device https://bitcointalk.org/index.php?topic=1388811.0), indicative of the number of people struggling, I would like to be prepared and this time do the 2FA properly and record the secret key so that I can have the 2FA on multiple devices and also recreate it in future if required.

I think the aspect of "Recording the Secret Key" of the 2FA can't be stressed enough, as it will allow you to easily recreate the 2FA in future on any new device.

The procedure was also described in https://bitcointalk.org/index.php?topic=1388811.msg22740326#msg22740326

"In 2.9.3, you want to go to "File -> New\Restore -> Standard wallet -> I already have a seed"... Enter your 2FA seed... You will then be asked if you want to "keep or disable 2FA"...
You can either "keep" and reset your Google Authenticator... Or you can select "disable" and it will create a special wallet that had 2 of the 3 private key chains required to sign the transactions. You can then send the BTC to a new wallet."


The only problem is that I'm running 2.9.0, and logging into my normal wallet and then performing the steps
File -> New\Restore -> Standard wallet -> I already have a seed, and entering my 12 words for the seed,

it goes into "please wait"

After more than an hour of no progress, I canceled by closing the window.

1)  Does it work on my version of Electrum, ie 2.9.0
2)  Did I perform the procedure correctly

Is there anything that I should do differently?

I'm new to Electrum and in the past only made use of online exchanges for keeping my coins.

I have now installed Electrum yesterday, first by following the instructions on the Electrum website (https://electrum.org/#download)  but unfortunately it does not include how to run Electrum, and then using the Getdeb repository which had Electrum 2.8.3-1~getdeb1 in any case.  The Getdeb repository (Xenial archive.getdeb.net) installed a link under Internet in the menu, thus it was idiot-proof

Now it works perfectly!   Receiving funds and making payments without a hitch.  However, while Electrum is open, my hard drive is continuously busy.  The activity stops immediately when I close Electrum.

The Electrum running is Electrum 2.9, which is a bit strange as I installed 2.8.3-1~getdeb1 last using the Getdeb repository.

I have the latest Linux Mint 18.2 with all the fix packs installed up to level 3.
The PC is an x79 based 3820, with 512GB SSD as the primary drive and 64GB ram.  (thus swapping is unlikely and was confirmed as 0 in the monitor)

I don't see any suspicious process activity using the system monitor, nothing is mentioned in the Electrum documentation or in this forum that I could find and Google did not indicate anything either.

Some questions now to eliminate the possibility that the Electrum has been compromised,
- Is it normal for Electrum to perform continuous hard drive operations?
- What is Electrum doing on my drive?
- Can this excessive hard drive activity be controlled at all using a user selectable switch in the GUI of Electrum?

Thanks
