SSD space lost after nasty Yosemite crash

[Rob2too]

Hi

I had a nasty crash which produced a total lock up and "Your system has run out of application memory" after a very prolonged beachball. On restarting via power button I appear to have lost about 16GB of SSD space with Grand Perspective reporting it as Miscellaneous used space. I have verified and repaired disk in normal boot and recovery mode.

The amount of space lost is an estimation based on what I had free a couple of hours before the crash

The OS reports SSD size as 499GB with 140GB available and 359GB used

Both Grand Perspective and Disk Inventory X show capacity as 465GB ! with 335GB used

sudo du -chxd 1 /

gives me :-

34M /.DocumentRevisions-V100
60K /.fseventsd
0B /.PKInstallSandboxManager
1.9G /.Spotlight-V100
0B /.Trashes
0B /.vol
55G /Applications
2.3M /bin
0B /cores
4.5K /dev
1.0K /home
15G /Library
1.0K /net
0B /Network
154M /opt
6.1G /private
1004K /sbin
4.4G /System
226G /Users
561M /usr
23G /VM
4.0K /Volumes
332G /
332G total

Any ideas clues help or suggestions would be very much appreciated

Yosemite 10.10.2

restart to your recovery system (Restart while holding Command-R)
Run Disk Utility, and do the Repair Disk on your main partition.

Have done this from recovery mode and a USB boot stick... with no change

There is a free utility called DiskWave:

You can use it to search your drive to discover what is taking up all the space.
