"Regarding CCC Version 4
I previously had CCC version 3.5.7, and my main disk utility was TechTool Pro version 7. Over the time I used CCC 3.5.7, I had a problem using both the "Volume Structures" test and the "Volume Rebuild" tool of TTPro 7 on my primary disk (running from my backup disk). In both cases I would get an error message saying "Unable to unmount disk". I had to use the Terminal in Mac OS X 10.9.x to force quit the target disk.
Since updating CCC to version 4, that problem has disappeared.

"H-P Printer/Scanner Software from Apple Fails in Mac OS 10.9.x
The recent Apple-released update of Hewlett-Packard printer/scanner software (ref: Sept. 30th HP Drivers v3.0 for OS X) does not fix the bad "SAVE" function in "HP Scan.app." See this 36-page HP forum discussion: HP scan incompatible with Mac OS 10.9 (Mavericks)?
Although the leading post states that the problem is "solved", it is not, as shown on the following 36 pages! My scanner is a HP Scanjet 4070 Photosmart Scanner, and I have exactly the problem with the latest version of H-P's "HP Scan" software as most of the other folks who posted on that forum. The problem has existed since Mavericks, and has yet to be solved.

In my case everything works up until "Save" is clicked (or the disk icon for "Save" is clicked). The resulting saved icon is black, or has horizontal black/white bands, depending on the file format chosen. I am forced to do a screenshot of the preview of the scan and then to save that. Not acceptable.
(Can you copy to clipboard in Scan app and then paste in Preview?)
Negative; there is no provision in HP Scan for copying the contents of the scan preview either in its menu or with command-C. I tried "Send", which brings up a template with an option for "Open in an Application", and I chose Graphic Converter. I got this error message"

I don't see that model in the Apple doc (on drivers) list of supported HP printer/scanners, so I checked the HP Scanjet 4070 Photosmart Scanner drivers page but the last Software/Driver update for OS X there was in 2011. Wasn't able to reply to Bill personally yet but wondered if OS X's Image Capture or Preview worked with it? (I realize that software's basic scanner functions are not as good/complete as a mfr's model specific scan app.)
Update: Bill later replied to that question:

"Although my H-P 4070 Photosmart Scanner shows up in my Mac's "System Report" under "USB", no device shows up in the "Image Capture" window, and nothing in the "Preview" window either.
-Bill"

Thanks for the follow-up Bill. (This scanner problem almost rings a bell from the past, but can't place it now. From 2008-2012 I used a HP AIO C7180 w/scanner in OS X 10.5.x and 10.6.x. It had wifi and scans via wifi had noise in the image. I rarely used it but it failed in 2012 (IIRC) and replaced it with an Epson AIO. Not used the Epson for scanning in Mavericks however as only the mac mini has 10.9.x on it and that mac is very rarely used.)
