Have searched in vain, including hereon, to find means of copying (Excel) file from hard drive to CD-ROM disks of all types. The READ ONLY stops it very effectively. Googling includes half-dozen methods but most if not all apply to hard drive removal and that I've done. The disk Properties uncheck of Read Only is meaningless. When do so and then try copying, same interference. Back to Properties only to find the click has mysteriously been reinserted. A KB at MSN explains why the Read Only is there and even suggests various removal instructions. Found these much above my limited tech savvy. Will appreciate learning a simple means of doing this from any of you more knowledgeable volunteer support specialists.
