Spinrite is only $89/license, and corporate users need four licenses per site: ------- Included Stuff Follows ------- GRC's Software Purchase & Download System http://www.grc.com/cs/licenseinfo.htm Consultants or Corporate sites may use our software on any of their client's machines, or on multiple machines located at a single physical site, if they own and maintain four copies of the software being used at its latest revision level. This simple and easily audited requirement allows consultants or site licensors to qualify for such use by upgrading and/or purchasing whatever additional copies of software are required to have and maintain a total of four copies at the latest revision level. --------- Included Stuff Ends --------- ISTR hearing on the SN podcast that 10 licenses gives you a enterprise license at multiple sites, but you'd have to write to GRC at the address on the License Info page to confirm that. FWIW in 2008 Steve Gibson said: "... enterprise license is 10 copies of SpinRite. So that's $890." Security Now! Transcript of Episode #131 http://www.grc.com/sn/sn-131.htm Amortized over 260 laptops $890 is less than $3.50/laptop. The downloadable Spinrite installer creates an ISO that boots FreeDOS, but with a little google-fu you can also tweak it to boot Win98 (I did) or to boot from a USB stick (I also did this). If your PGP command-line installer will run from a true DOS prompt you could add it to your bootable Spinrite media and set up a boot menu .... you can also apparently install Spinrite on a BartPE bootdisk/bootstick, http://www.google.com/search?q=spinrite+bartpe and I even found that the PGP installer will also run from a BartPE bootable device. !NEW BartPE To USB Flash Stick Utility - The CD Forum http://www.911cd.net/forums//index.php?showtopic=13784 GoCoding.Com - PeToUSB - Boot BartPE From USB http://www.gocoding.com/page.php?al=petousb "Tech Note: Customizing the WinPE/BartPE for PGP Whole Disk Encryption" http://supportimg.pgp.com/pgp_pe/Tech_Note_Customizing_%20the_PE_for_PGP_Whole_Disk_Encryption_july_08.pdf HTH!
