Blazkowicz Posted August 21, 2006 Share Posted August 21, 2006 yes, run chkdsk and it'll tell you. such as, if I run it on my C: partition I get this 3987395 KB total disk space. 1674800 KB in 14548 files. 4176 KB in 1582 indexes. 0 KB in bad sectors. 38767 KB in use by the system. 22000 KB occupied by the log file. 2269652 KB available on disk. 4096 bytes in each allocation unit. 996848 total allocation units on disk. 567413 allocation units available on disk.

JustGeorge Posted August 22, 2006 Author Share Posted August 22, 2006 But doesn't inly show that info during a boot-time scan and then only for your Windows drive?

Blazkowicz Posted August 22, 2006 Share Posted August 22, 2006 open a CMD window then you can run chkdsk whenever you want and on whatever drive.. (type chkdsk d: for instance) Link to comment https://www.neowin.net/forum/topic/488701-how-do-i-check-ntfs-cluster-size/#findComment-587808786 Share on other sites More sharing options...

+BudMan MVC Posted August 22, 2006 MVC Share Posted August 22, 2006 (edited) Another quick and dirtry method! is to create a file with say 1 character in it -- and look at the size on disk ;) edit: Another quick an easy method.. that only takes a couple of seconds to run vs how long chkdsk takes, plus lots more info grab ntfsinfo from sysinternals (FREE tool)..
