I have a similar problem described by the question posted to this forum labelled "OS X Mavericks upgrade - disk/partition failure". I, however, didn't stop the installation process. Instead, I continued with the option of later recovering/restoring the files from the Time Machine, believing that all data on my hard disk would be wiped out.
Mac OS X Mavericks was successfully installed, and all files/programs seems to be intact. What did I do right? In the case where there was a disk corruption, how could I determine,
1) which files were corrupted?
2) whether or not a log file was generated outlining the corrupt sectors/allocation units?
Also, how would I go about using Time Machine to restore the corrupt files (if any), as I have not done this before?
Any advice/suggestions would be appreciated.
Edit:
I suppose my question is whether or not the installation process did, indeed, fix the corruption. If so, where would I find the 'lost+found' folder (that is, if one exists)?
