3b1, antistatic tab removal

I have opened my 3b1 a few times during the past ~18 months to clean the
hard disk's antistatic tab (to stop hard disk whine). At the time this
operation was discussed (~18 months ago?), some posters commented that
the tab was unnecessary, and that it could simply be removed without
harm.
Has anyone removed their disk's antistatic tab? Any side-effects?
[BTW, thanks to you who originally explained this fix... I had already
had the original drive *replaced* (under warrenty) because of this
whine, then the replacement drive began whining, and I was getting very
agitated.]
Also:
My 3b1 ingests much dust. How do you/I remove the accumulated dust from
the opened 3b1? (I considered wiping the motherboard with an old
paintbrush, but worried about static (dis)charge.)
How would I checksum a diskette so that I could verify the integrity of
copies? How about:
$ dd if=/dev/rfp021 | sum
and perhaps better,
$ dd if=/dev/rfp021 ibs=4k obs=4k | sum -r
Does anyone checksum backups? Or is checksum inherent in cpio, so if
one can cpio -iBct (or cpio -iBc ?), then the backup is clean?
Thank you for any information.
Regards,
John.
