4I had to think hard at the "maximum possible sectors per cluster is 64", until I got it: 64 is indeed the largest power-of-2 you can represent in a signed byte: 128 isn't possible as the maximum positive signed byte value is 127.Ralf Kleberhoff– Ralf Kleberhoff2018-05-01 10:28:31 +00:00Commented May 1, 2018 at 10:28

3@RalfKleberhoff That does naturally lead to a followup question, though: if you're storing a power of two, why store the number itself rather than the exponent on the two?Daniel Wagner– Daniel Wagner2018-05-01 12:27:55 +00:00Commented May 1, 2018 at 12:27

@DanielWagner I absolutely agree. Especially as back then when FAT16 was created, shifting was definitely a cheaper operation than multiplying. But probably they were just happy to get it running, and not software-engineering it for decades into the future...Ralf Kleberhoff– Ralf Kleberhoff2018-05-01 13:04:16 +00:00Commented May 1, 2018 at 13:04

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. design-patterns), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
