Evening with John Phillips
I had the pleasure last Tuesday to spend an evening with John Phillips at the monthly Boston Computer Society Omnis User Group meeting. For those who dont know him, John is one of those old time Omnis users. ... If I do in fact get something wrong or misquote John, too bad! ... Although John knows A LOT about data corruption caused by past Omnis bugs, that was NOT the subject of this presentation. ... ** A short history of Johns involvement in rescuing data ** Preventative measures ** The structure of the Omnis data file ** The tools & steps involved in rebuilding a data file ***** A Short History ***** John has successfully rebuilt & recovered about a half dozen different Omnis data files over the years. ... 6) If you need to copy a bad hard drive (in order to send a SyQuest to John, for instance) you need to use a tool that creates an image copy of the drive. ... Over the years, John has managed to figure out the structure of the Omnis datafile. ... However, John has been able to figure out the scheme for each version of Omnis to this point. ... John first used Speed Disk, a disk optimizer thats a part of the Norton Utilities toolset, to see where the free space on the hard drive was.
