HDD Problem

[Salmon]

Alright so here is a thing, i recently moved a couple games to a different HDD in my system that i was using to install all my games on because some games ended up installing on the steam install directory and i don't have it set up that way don't know how it happened. So i had to do some interesting shenanigans and i moved all the games to the correct HDD that i want it on which is the one that has all my games on but there is a problem when i go to play the said games that i moved steam wants to re-download it and its because steam still thinks that said games are still installed on the old directory. So all i had to do was to delete it and reinstall it and select the correct HDD to install it on so it can recognize the files. Now to the situation according to steam it is reading the files at 5 kilobytes per second, now i know for a fact that my HDDs can read and write up to 100 megabytes per second. Why is steam reading so slowly? Really confused here and don't know why its doing this. Other times when i have downloaded and installed games i have monitored that sometimes the steam disk usage goes up to 20 megabytes per second, in the end why is the steam disk usage so slow especially now when i have to re recognize gigabytes of data. Any help and input is greatly appreciated.

Because it have embedded file integrity checking mechanism, and Steam download a list of checksums (most likely is an implementation of SHA algorithm, for example, SHA-512) recalculates checksums for all the files of the game, then larger the file, then longer

100Mb/sec its for big files on clean fresh formatted unfragmented HDD but most games use zillion small files and users install on system disk that high fragmented

If used the right way to move files using a standard algorithm, then there is no problem

Then whats a right way to move the files.

After moving games, now launch Steam Client and go to the game u moved in Library and click Delete Local Content to Uninstall it from old location. Then click Install and select the Drive + Library the game is now present on, then Steam will verify the game content files.

[Salmon]

right but the verification process is whats slow its going a a speed of 5 kilobytes per second.

What all drives are you using? Even 100Mbs is super slow
Plus Steam will never read this fast off a mechanical HDD.

i have surveillance HDDs in my system i got them for cheap and they have excelent read and write speed. the problem is that steam is reading off the HDDs at a speed of a few kilobytes making the process take an estimate of more than one year or something. I know how fast steam has read off my HDDs before around 50-60 megabytes on average so why in this situation where it has to read hundreads of gigabytes of data is it going so slow.

Depends on the game sometimes too (how compressed the files are); just let it finish. Some start off really slow, they speed up as they get further into the verify process.

see its the opposite it starts at like 200 megabytes per second dong ask me how but then it just keeps slowing down at the current rate it will take Doom to "discover existing files" about a year and ive let it keep going for about 2 hours. and most times disk usage will stop completely
