That's called Live File System format, as shown by ]http://windows.microsoft.com/en-US/windows7/Burn-a-CD-or-DVD-in-Windows-Explorer.
I've never tried it myself. I do have a real USB-stick. So I can't tell if this is the normal behaviour (I don't think so) or if something is wrong with your drive (did you check it's in DMA mode, not in PIO mode?) or it was just a bad disk.
Anyway, http://www.isobuster.com/isobuster.php shows the program does support that Microsoft specific format, so there definitely is something wrong with that disk, whatever the cause.

win7 multisession dvd reads ridiculously slow
never had tried formatting a dvd as multisession before...now i know why
burned it last night on a win7 home edition pc (single layer dvd)
trying to read it on my win7 enterprise pc...one of the files copid fine..normal speed..with the other 3, windows explorer gets slower and slower and finally justhangs, the progress bar changes from green to red
i tried to find something via google about this and no luck
any ideas? thanks much
BTW i used the windows 7 burning wizard to format as multisession (where it says "use disc as a usb drive" or something like that...yeah, what a usb drive...took about an hour to burn 4 gb of data, now i cant read it)
***DVD drive is an ASUS DRW-2014L1T ATA
***ISObuster not working. After attempting extract from disc, it simply flashes a dialog for a split second and does nothing.
Found a free app called bad cd dvd reader. When I try to make a copy of the disc it crashes the program. It doesnt really amtter because I dont think it is recognizing the multisession disc.
