Re: why bitcoind started download bloks from the very begining?

Not likely, as individual block files are not interchangeable... my "blk01881.dat" file will not be identical to yours.

As above, did you move just the "blocks" or did you move everything including "chainstate"? Huh

I copied everything

can you suggest, where I can read about how bitcoins works?
everything I found were about general principles, but I interested to learn how file bitcoins organised....

A bit here:

thank you very much!

You said that the machine you had it on before is no longer working. How did it die?
In theory, once a block is written it should be good forever, but if there were hardware / OS issues and one or more of the block files got corrupted, even one from 6 years ago got corrupted it's going to re-download the entire chain. Sad

it was a Raspberry pie. OS was on microSD card and blockchain data on the attached USB external HDD. so, one day it rejected my ssh connection and after hard reset it died.

I don't know ether it was corrupted SD card or whole computer.

But I managed to get to blockchain data I downloaded so far. and I am trying to use it, but I think it wouldn't work well.
