Bitcoin Core makes heavy use of CPU, RAM and disk IO. Hardware defects might only become visible when running Bitcoin Core. You might want to check your hardware for defects.
- memtest86 to check your RAM
- to check the CPU behaviour under load, use linpack or Prime95
- to test your storage device use smartctl or CrystalDiskInfo
ram and cpu are fine, and i believe the drive also is working fine. i took the files and moved them to another HDD. still same issue on launch.

Yes, file corruption can not be fixed by moving the corrupt files from one storage to another.
alright, how can i know which file is corrupt and fix it?

Package manager
What package manager exactly?
Does the error happen with the recent official Windows binaries from https://bitcoincore.org/bin/bitcoin-core-27.0/ ?
Direct download from https://bitcoin.org/en/download.
I hope its called a package manager, or its my mistake for filing it as such.
alright, how can i know which file is corrupt and fix it?
I think a -reindex-chainstate should be good enough.

-reindex-chainstateshould be good enough.
alright, where can i run this command though?

still same launch result.
Is this an external HDD? What is the filesystem?
Is this an external HDD? What is the filesystem?
Windows 10, internal HDD.
Which filesystem is the HDD that holds the datadir? For example, NTFS is a possible filesystem.
In any case, this error should not happen, unless there is a serious bug, or the data on the storage is corrupt. If -reindex-chainstate does not work, you can try -reindex, but they will only fight the symptom temporarily. The issue will come back at some point, because if it was a bug, it will remain unfixed, or if the storage is corrupt, it will also not be fixed by setting a flag in the software.

i just downloaded the v27 of bitcoin core and it launched past the error. This was the launch result:
is it supposed to do this? i already had 590gb of the blockchain downloaded.
as for the filesystem its NTFS yes.

If you told it to reindex, it will reindex.

Alright, its been "Processing blocks on disk" for about 2 days now, without internet.
Is it just reading and verifying whats there or something else? also does it normally take so long?
You can check the progress window to see the progress and what it is doing currently. Also, you can use the task manager to see the CPU usage, or IO, to see whether it is doing work.

as i said, it says "processing blocks on disk" with about 6 years remaining. But its gonna take about a week at this rate to do so, thus why im checking if its something normal. is it?
i got it on an ssd connected by usb to a laptop
How long IBD takes depends on the speed of your CPU and other hardware components.

if i remove the ssd and plug it to a more powerful pc, does it continue? or will it restart?

Closing for now, but please leave a comment if you have more information indicating that this is a bug in the software, as opposed to a user error, or corrupt hardware.
