I have an older laptop...it is a Fujitsu Lifebook E342 with the Fujitsu DVD-ROM kit added (PN #FPCDVD04), including the Margi DVD-to-Go™ PCMCIA card. This drive will recognize any and all commercial CD's & DVD's, it will play all burned CD-R & CD-RW's, and it will play, without problem, burned VCD's...but, when I put in an copy of a DVD-R or DVD-RW (that I made for archival purposes), it does nothing! When I try to access the drive through 'My Computer', it says 'please enter disk' (in other words, it does not recognize at all that there is even a disk in it). The same disks will work on my standalone DVD player, as well as in my desktop PC. Are there any suggestions for a workaround for this? I have updated my aspi already. Not knowing who is the actual manufacturer of this DVD drive creates a problem (anyone out there know?), as I am unable to look up compatability or whether there's a firmware update for it that might help. I have tried, without success, to contact Fujitsu for help (I guess, with it being older, they can't be bothered). Any and all input would be greatly appreciated!!!
