I just used Acronis Disk Director to re-size partitions.
After completion (with errors) the drive shows the correct capacity a free space in Disk Management (and in Acronis Disk Director)(209.6 GB with 152.0 GB free , however, Explorer shows 57.6 GB with 976 MB free. This is the old size before the partition re-sizing. I ran CHKDSK which fixed some errors but did not change the partition sizes.
Also, ff I right click on the volume in the upper pane of Disk Management, it shows the smaller size while the partition map in the lower pane shows the larger size.

Excellent suggestion. I did contact Acronis and they were very helpful It took 3 remote access sessions and a couple of phone calls but the problem was eventually solved by a sequence of running CHKDSK, resizing the partition in Acronis to match what Explorer thought it was. Rebooting, with another CHKDSK and then resizing to the desired size. Everything was then in agreement.
