Your post was somehow misleading and confusing or totally off that was why it was deleted maybe someone did reported it ...
Let me point out your post errors
It so sad your previous keywords have been lost
I don't know what you meant by keywords here but it's off , the OP did say he lost his wallet not his keywords
There's no point in asking for help because no one can remove the private keys
I don't know the private keys you want to remove maybe you misterpreted the OP and thought he lost his keys on a hard drive and you're probably saying no one could help to recover it .... apart from that it really sucks to know what you meant there
Since you have lost this pen drive , look carefully where you kept it
This is totally two different thing you used the lost and you are advising to locate where its being kept
Lastly
Make a new address, save it well so you don't make such a mistake later
This is completely off point
Instead you meant creating a new wallet, backup the seed to a safe place in a cold storage format.
Note your mistakes and learn from it...
