I did the command line chkdsk C: /f and because it was a mounted partition, I answered "Y" to have it run at bootup. I followed this with each of the partitions on each drive. The first partition on the older WD drive showed some of the indices were invalid, and it made a number of changes in these and found some orphaned files and put them some place. When I rebooted, the chkdsk for the boot partition was run, and nothing was detected. When it completed the check previously, all the partitions were checked. This time, when C: was complete, the computer was re-started and the bootup was completed. In DOS days, those orphan files were listed as file.001 and so on. I have not checked the disk since startup, so maybe they are there in a special folder. Some of you know where I will find them. There is also a log file which I imagine contains all the info about what was corrected. Thanks for your help. It always amazes me that so much assistance is available here.
