Hi - I have a Fujitsu Laptop (Lifebook N5010) with a Toshiba Optical Drive (DVD-ROM SDR6112F)which for the last year or so I have been burning CD's and DVD's (DVD-R) with no problems. Now the drive no longer will recognize a blank DVD. CD's are no problem - and I can play a DVD (i.e., a movie rented from Netflix. I have bought two different sets of blank DVD-R's (Memorex and HP)- but upon inserting it into the drive - It fails to recognize it. If I Right Click and go to properties it shows Used space, Free space and Capacity all with 0 bytes. For file System - some say "Unknown" - some say "RAW". I put in a dvd which I burned with no problem a month or so ago - and it shows the File System as UDF. Does it sound like the Blank DVD's I've bought (I tried about 20 from both the Memorex and HP and none worked)or are those DVD's the latest technology and my Optical Drive can't read a DVD with a RAW file system? I'm totally perplexed and wondering if I should just buy an external Dvd burner? I hope someone here can help me. Thanks so much in advance NC

I am questioning the fact that your optical drive can burn ANY DVD media. The model name indicates a DVD reader. Below is something I found using Google. Note the supported media. Toshiba -> DVD-ROM SDR6112F Manufacturer Toshiba Model DVD-ROM SDR6112F Supported Writing Method: [DAO/SAO] [RAW SAO] [RAW SAO+SUB] [RAW DAO + 96] BURN-Free supported: [BurnProof] Best Writing Speed: Supported Media: [CD-R] [CD-RW]

That is very interesting as I have burned probably well over a hundred DVD's in the last year. I just ran a diagnostic scan using Everest - and it shows the following: Description: TOSHIBA DVD-ROM SDR6112F Firmware Revision : 1F32 Device Type: DVD-RW Interface : ATAPI Supported Disk Types: DVD-ROM - Read DVD-R - Read + Write DVD-RW - Read + Write It shows many other formats supported but I believe the ones above are the ones I need.

Problem solved - The problem was I had always used Roxio 7.5 for burning my Dvd's - and no doubt during the install process it installed certain Codecs. About the time my blank Dvd's couldn't be read - I had upgraded to Roxio - which must have changed the Codecs making them incompatible with my optical drive... So I Uninstalled 8.0 - reinstalled 7.5.. And it works just like it always had.
