[anomalous]

How does one determine what cluster size an NTFS drive is using in XP Pro
SP2?

Thanks!

Open a command prompt (Start ... Run ... cmd) and type

fsutil fsinfo ntfsinfo c:

Where you require this information on C: (etc)

I believe it works on XP (all releases) and on the Windows Server products
also.

Mike

The Report in Disk Defragmenter gives cluster size.

Hope this helps.

Why I asked is after reading your reply I tried the command (WinXP SP1)
all I got was a black screen then back to my desktop.

Run CHKDSK on the drive in a Command prompt. The final three lines are
allocation size and usage - the size is the cluster size. Unless you
did a conversion from FAT 32 without precautions it will be 4096 (4K) -
such a conversion may result in 512 bytes

Thanks, Alex. Actually, it is your article on aumha.org regarding this issue
that prompted me to check. As it turns out, the partition I was concerned
about is indeed 4096 bytes. I appreciated the article and will probably grab
BING due to that recommendation.

Thanks again,
Mark

Thanks, Mike. This command does indeed work, as does Alex's suggestion of
running the chkdsk command.

Thanks,
Mark

Ahhh stupid me...it runs in Dos mode but not from start and run , fo
some reason..also stupid me again, for some reason I missed the )
after the C when I copied from your message and pasted it into the run
command, damn thing is so small these old eye's didn't spot the error.

Sorry for any wasted efforts on your part.

There are several ways to do this, and I see you've already
gotten several answers. I'll add another answer--the one I think
is the easiest of all:

In My Computer or Windows Explorer, find (or create) a small file
of a few bytes, right-click on it and choose properties. Listed
there will be its size and also "Size on Disk." Assuming that the
file is smaller than one cluster (and it will be if you chose a
file no larger than 512 bytes), the Size on Disk is the Cluster
size (regardless of the file system).

Like my original post said

Step 1. >> Open a command prompt (Start ... Run ... cmd) >>
Step 2.>>and type fsutil fsinfo ntfsinfo c:
Glad you got it figured out in the end.
