Apparently some CD recording software strips the El Torito (check out Wikipedia for the specs) bootimage from the ISO image. <BR/><BR/>That bootimage contains your crucial data and is not visible when you browse the content of the rescue disk so a valid and invalid rescue CD will look the same. <BR/><BR/>In my case the Software that came with the Notebook (some Roxio crap/shovel ware) stripped the TrueCrypt boot loader from the ISO image before burning it to CD. No comments, no warnings, nothing. Even when you switch on "verification" it claims to have written everything just nice.<BR/><BR/>I copied the ISO image over to a Linux box and burned it with k3b and it works perfectly.<BR/><BR/>If you suspect that your recording software does the same, try to read back an image the burned CD. If that image is only about 500-600kb than you recording software is crap. It should be about 1.8mb. Ideally it should be exactly the same size as the one that you started with.Unknownhttps://www.blogger.com/profile/01440441834048156939noreply@blogger.comtag:blogger.com,1999:blog-6936134049134982166.post-50206395822594010692008-11-25T01:31:00.000-05:002008-11-25T01:31:00.000-05:00This TrueCrypt "let's prevent stupid users from sh...This TrueCrypt "let's prevent stupid users from shooting themselves in the foot" requirement that people create a restore disk is incredibly asinine and patronizing. Let's keep in mind that many people install disk encryption simply because they're fed up with being treated like kids, spied on, or otherwise harassed. It seems totally whack to assume that these people would be willing to learn the various technicalities of disk encryption but not burn an ISO file if they needed to recover the system.<BR/><BR/>Maybe their lawyers told them to do this. It's still pretty damn irritating.Connelly Barneshttps://www.blogger.com/profile/02568908952592933174noreply@blogger.comtag:blogger.com,1999:blog-6936134049134982166.post-80014846751361985002008-07-27T16:30:00.000-04:002008-07-27T16:30:00.000-04:00Hi Rizzy, Interesting how my problem has the same ...Hi Rizzy, Interesting how my problem has the same symptoms as you describe. However, I burned the ISO to CD on a separate machine to the one I was installing TrueCrypt on, and it failed the compulsory Rescue Disk test.Hayden Tennenthttps://www.blogger.com/profile/07068860915794475455noreply@blogger.comtag:blogger.com,1999:blog-6936134049134982166.post-73522345088674554512008-07-26T20:04:00.000-04:002008-07-26T20:04:00.000-04:00I burnt the ISO onto a DVD using Nero Express, it ...I burnt the ISO onto a DVD using Nero Express, it didn't recognize the disc immediately after the burn though -- you have to eject it and reinsert it. If you try to browse the contents of the disc (using windows explorer in my case) it will appear empty though it has the label 'TrueCrypt Rescue Disk'. Overall, everything seems to be working fine.Unknownhttps://www.blogger.com/profile/01498958048007841265noreply@blogger.comtag:blogger.com,1999:blog-6936134049134982166.post-67398762687174920272008-07-22T06:10:00.000-04:002008-07-22T06:10:00.000-04:00I have just attempted to use Nero Express 6 to bur...I have just attempted to use Nero Express 6 to burn the Rescue Disk ISO to a blank CD. It gives the CD the correct name, but the resulting disc does not contain any files. I have got myself a coaster here too.Hayden Tennenthttps://www.blogger.com/profile/07068860915794475455noreply@blogger.comtag:blogger.com,1999:blog-6936134049134982166.post-32374835919442273992008-02-25T01:22:00.000-05:002008-02-25T01:22:00.000-05:00Just popped past to say I'd really love to see spe...Just popped past to say I'd really love to see speed comparisons, I'm just using TrueCrypt in enclosure mode but it's annoyingly slow. I'm seeing ~40MB/s and very low CPU usage from a drive that's capable of 90MB/s or more. So i'm trying to find out whether there's anything faster on the market.Mozhttps://www.blogger.com/profile/07450274402965786918noreply@blogger.com
