Best way to check data corruption on network drive on Mac?

[Combat squirrel]

As title - I'm trying to sort out a friends lime unraid server - its got some really weird file integrity issues - I want an app that will read/write data to a network drive directory and check its ok or not - I was thinking of something like 'F3' (Mac version of h2wtest) but it says in the notes it will only write to a usb and delete data on the read/write device - im not sure if I can point it to a file directory only or not.

Is there a safe read/write app or software I can run to check the server is reading/writing data properly on Mac/Mac network drive?

Can you check it in disk utility?

No don't see the network drive in there - also the network drive is 32tb in size - so, I was hoping something I could define what I want with - i.e. write 15gb of data and read it back sort of thing
