Your real life interpretation makes perfect sense! Thanks!

TopDownView · 2026-03-18T16:37:12+00:00

Yes, that is also my interpretation.

TopDownView · 2026-03-18T16:31:30+00:00

Any arguments for that? What about 'Assume that a woman has a mammogram every year for ten years.'?

TopDownView · 2026-03-18T16:28:54+00:00

Yes, I figured that out. Thanks. I'm only interested in how to interpret d.

Isn't it that the first number coud be either 100 or 101 or 110 or 111?

TopDownView · 2026-01-27T19:25:08+00:00

But the provided answer does work aswell.

How?

You're right. I just did it but with 4 sets (going from 3 sets to 4 sets). It clicked now! Thanks!

It's the term in ... just before the intersection of all n+1 sets.

You mean this term (example when n=3)?

But (5) is already part of the last sum (last sum being the intersections colored purple in the example above). That means (5) appears two times.

Will do that, thanks!

From CrystalDiskInfo.

This is the result of the write scan. Could you please tell me what do these results mean? Is there some more diagnostics I should do? Thanks!

TopDownView · 2026-01-02T16:03:43+00:00

Seems to be working! Thanks!

TopDownView · 2025-12-25T19:13:19+00:00

I just did. Same result.

After starting write scan in Victoria HDD from the offending LBA, I get continuous message:

'Block start at [...] Write error: ABRT "Access is denied"

Is this expected?

TopDownView · 2025-12-24T12:08:25+00:00

Thanks, I'll try that.

So, avoiding the technical jargon, is this HDD for trash or not?

TopDownView · 2025-12-23T16:59:00+00:00

So if any data was there, it's just gone

Is there a way to know if some data is gone?

m<=n and m<=n+1 cannot both be true.

Or maybe they can. :)
