Hi Everyone, I'm wondering if anyone has seen a way of limiting the
size of a USB storage device, ie up to a 1 Gig device, or a way of
stopping USB attached external hard drives while still allowing USB
key/drive/thumb drives etc to be used? Thanks.

My 'USB drive letter manager' can handle this.

You can define drive letters or mount points depending on
the size of the attached drive. If you let it mount large
drives to a folder on an NTFS drive and remove all
access rights to the parent folder then the user cannot
access it.

Sample: You create a folder C:\LargeUsbDrives and remove
all access rights for the user. Then you configure this
in the USBDLM.INI

[DriveLettersSize1]
MinSizeMB=1024
DriveLetter1=C:\LargeUsbDrives\%devname%


USB drives <1024MB ('real' MB) stay untouched, drives >=1024MB
are remounted to C:\LargeUsbDrives\%devname% where %devname%
is replaced by the drives device name. If the folder is in use
then trailing numbers are used.

Great, thanks, I will check it out.

If it works for you I can add a feature that immediately
removes the drive instead of remounting it to somewhere
else. Furthermore a setting is needed to ignore a USBDLM.INI
on the attached drive because the settings there would
overrule the setting in the global USBDLM.INI.
