Missing checkbox for "compress disk drive to save space"

[Bill Pierini]

Hi, all. Have a basic disk with three partitions. (On an external RAID5
enclosure.) Drive "X" does not show the checkboxes to compress (which I
don't want to do, but want to make sure it isn't) or "Allow indexing". The
RAID claims everything is healthy, the other two volumes have no problems
and the info is displayed. Any thoughts on how to show the checkboxes?
Sadly, this is part of an Exchange 2007 file set and removing the partition
and recreating could be a problem in itself. This is NTFS on a Windows 2003
x64 system.
Thanks (please forgive the cross post)
Bill

Check that the Reg_DWord 'NtfsDisableCompression'

is set to 0 (zero)

HKLM\SYSTEM\CurrentControlSet\Control\FileSystem

Dave, thanks for the tip. Since this is a global setting, why would it help
an individual volume show the checkbox? In general, the system allows
compression, though it is not used. The key does not exist on this server.
thanks
Bill

From the command line;

fsutil fsinfo ntfsinfo C:\

(to see that bytes per sector is 512 and bytes per cluster is 4096)

then also

fsutil fsinfo volumeinfo C:\

(to see that compression is supported)


Then you may want to run;

chkdsk /r

from the recovery console but be sure your backups are tested and current
before hand. Also see this article.
