Hidden attribute removal

How do you remove the hidden attribute on the _Rescue folder of a Compaq running Windows ME. The folder is checked as hidden and it is greyed out. The ATTRIB from the DOS Command prompt will not work as a file in this folder is active. The drive is 60G and DOS 6.22 does not see the drives at all, therefore ATTRIB under DOS 6.22 doesn’t work. Ontrack’s DOS_UTIL hangs when attempting to access the drive. Is there a stand-alone non-windows utility that will access file/folders and their attributes on large drives?
