This drive (Drive E) always has a CDRW disk in it, used as a backup for various data which is being changed daily... checking info, records data, changes in letters or documents, etc, all of which have given me no problem until this week. Suddenly everything on the disk is "Read Only" whereas nothing can be changed or added. Going into the drive's properties, then removing the "read only" check from the page brings up a "Access Denied" window which I can click on ignore or ignore all. That clears the "read only" check BUT only until the disk is accessed again or the properties window is opened to double check which reveals that the disk is still listed as "Read Only". I can use another disk drive (Drive F) in the same computer to format another disk to be used as a large floppy and as long as it remains in that different drive, all is well. I can add info to the disk, change info, or delete info with no problem encountered. The drive folder itself (directory) is listed as "read only" but the info within is not which apparently is common. However, as soon as I switch this newly formatted, info loaded, usable disk into the problem drive (Drive E), it is suddenly a "read only" disk and there is no way that I can find to permanently get rid of that attribute, the end result being that it is worthless to me. Switching the disk back to "Drive F" shows that the attributes of the disk are indeed "Read Only" and cannot be changed. What am I overlooking?
