Broken in Mavericks - scanning with HP scanners

Scanning in OSX Mavericks using HP scanners and all-in one printers has taken a turn for the worse after the install of Mavericks.

Main symptoms is that it all looks like it is working but the saved image comes out as black (or white) with horizontal lines on.

Hopefully the really anoying 1% power drain caused by the  HPScanJet manager button monitoring process will also be fixed.  As the scanner is only plugged in when I need to scan why TF would a scanner specific process be active when there is no scanner attached ?

Some folks have worked around using Preview or Image capture but some models of scanner are not supported by those applications. However other workarounds using the

HP Scan -> scan to print -> Save print as PDF
or
Using Adobe Acrobat full version -> Create PDF from scanner then Save image as JPG.

Software updates are being made available by HP in batches of scanner types. Check out here for new software for your scanner.

Broken in Mavericks - Major widespread Data loss situation - Mavericks + External Drives + WD Western Digital software

Please be aware that there are serious data loss issues ongoing with Mac OSX Mavericks and Western Digital drive sofware. Both the Apple support and WD forums have multiple customer reports of total external drive data loss.

The data loss is not limited to systems activly using the WD software and drives, other vendor external hard drives are being lost. 

Personally I just lost 1TB of Time machine backups on a Iomega external drive. I did have a WD myBook for a while about 2 years ago but was not aware the WD drive software was still active on this machine.

Current advice from Western Digital is to uninstall the WD drive software before going to Mavericks. Uninstaller is here 

This situation as already caused a lot of digital pain, loss of data and as a technical person makes me sad in so many ways.

This is the set of ugly messages from Disk Utility as it fails to repair the damage to

Only solution Erase, Repartition and make a new volume. The disk was stuck for in a not mounted state and not able to be erased saying disk could not be "Un mounted." Fix for that was to find the running fsck_hfs process and kill it. Pointed TimeMachine at the new volume and replaced the Old volume name.

To the data distruction digital hall of shame we add ....... Western Digital

and for lack of governance and oversight of vendors ... Apple

You really ought to do better.
