Blacky Posted January 25, 2007 Posted January 25, 2007 (edited) Hello All! First, sorry for bad english! =( My trouble: DVD-RW NEC ND-3540A firmware v.1.04 (last oficial) Don't understand all DVD-R! When DVD-R loaded, in My Computer page - F:\DVD-RW drive -> changed to F:\CD-R drive, and show info: Disc capasity = 0 byte, free = 0 byte! Runned ImgBurn in Discovery mode showed: _NEC DVD_RW ND-3540A 1.04 (ATA)Current Profile: DVD-R Disc Information: Status: Complete Erasable: No Sessions: 1 Supported Write Speeds: 2x; 4x; 6x; 8x; 12x; 16x Pre-recorded Information: Manufacturer ID: MCC 03RG20 Recording Management Area Information: _NEC 5XT6378S211 DVD_RW ND-3550A Physical Format Information (Last Recorded): Disc ID: 0@P-!-00 Book Type: DVD-R Part Version: 5 Disc Size: 120mm Maximum Read Rate: Not Specified Number of Layers: 1 Track Path: Parallel Track Path (PTP) Linear Density: 0.267 um/bit Track Density: 0.74 um/track First Physical Sector of Data Area: 196?608 Last Physical Sector of Data Area: 1?866?111 Last Physical Sector in Layer 0: 0 If select Tools -> Drive -> Secter Viewer = i can view all sectors with data on DVD-R, very good! But why windows don't see DVD-R??? Why detect it like CD-R??? If You can help me, please - help it! Problem NOT in ImgBurn! Problem in drivers/OS/drive... or i don't know in what else... maybe in cdfs.sys??? OS: Windows XP SP2 Don't remember, but under SP1 i see DVD-R normal... maybe... many time ago was this... P.S. Maybe this was good if add function some like "All sectors -> To ISO"... in this situation it's be very helpful... thanks! With best regards Blacky! -=Added later=- Utilite Nero CD-DVD Speed show this info about DVD-R: Nero CD-DVD Speed: Disc InfoBasic Information ??? ?????: : DVD-R Book Type : DVD-R ????????????: : Verbatim MID : MCC 03RG20 Write speeds: : 2 X - 4 X - 6 X - 8 X - 12 X - 16 X Blank Capacity : 4.38 GB : 4489 MB : 4707319808 bytes Extended Information Layers : 1 Usage : General Copyright protection : n/a Recorder information : recorded with _NEC DVD_RW ND-3550A Disc Status : Closed Raw Data Pre-recorded Information in Lead-in (0Eh) 0000 - 01 40 C1 FD 9E D8 52 00 02 85 0D 0E 88 9A 80 00 - .@....R......... 0010 - 03 4D 43 43 20 30 33 00 04 52 47 32 30 20 20 00 - .MCC.03..RG20... 0020 - 05 88 80 00 00 00 02 00 60 0E 19 00 C4 D3 05 00 - ........`....... 0030 - 18 EE 90 7C 78 FB 90 7C FF FF FF FF 71 FB 90 7C - ...|x..|....q..| 0040 - 18 6A DC 77 51 6A DC 77 00 00 16 00 02 00 00 80 - .j.wQj.w........ 0050 - 30 00 00 00 18 00 00 00 30 00 00 00 FC D3 05 00 - 0.......0....... 0060 - 40 00 01 00 0B 00 00 00 04 D3 05 00 4E 00 4E 00 - @...........N.N.

LIGHTNING UK! Posted January 25, 2007 Posted January 25, 2007 What exactly did you do to burn the disc? Did you burn it in 'Discovery' mode? Discovery mode doesn't burn actual (real) data, it just burns zeroes!
Blacky Posted January 25, 2007 Author Posted January 25, 2007 No, i don't want burn disc! I only isert already burned DVD-R, and system don't recognize it! But ImgBurn can recognize it in Sector View mode! And i can see data in hex view! Why Windows see 0 bytes??? I can write on my dvd-rw DVD-R but can't read it... Maybe You can help?
LIGHTNING UK! Posted January 26, 2007 Posted January 26, 2007 Perhaps the disc has no valid file system on it that windows can understand?
Blacky Posted January 26, 2007 Author Posted January 26, 2007 Perhaps the disc has no valid file system on it that windows can understand? No, disc have good file system! On others PC or with others DVD drive - disc readable good! Some strange with NEC series ND and DVD-R... in one beautiful day - system stoped recognize DVD-R... Some people say - cleare you laser and disc recognized againe, some say - in windows sp2 - after running DVD players like Power DVD or Windows Media Player 10 - DVD-R discs stand don't understanded by system... If DVD-R cleare (not writed) - system see it! I can write on it! But after i write data - eject - insert againe - disc don't recognized like DVD-R! =(
LIGHTNING UK! Posted January 26, 2007 Posted January 26, 2007 I don't know then, sorry. The only sure fire way to force it to read a disc is to eject it, shut down the pc, boot it up again and then insert the disc whilst the 'my computer' window is open. If you have autoinsert enabled the OS should attempt to read the contents of the disc automatically, if you don't you'll need to 'refresh' by pressing F5 or whatever. If it can't read what's on the disc then you're stuck. Try putting a different drive in that same pc and see if it does the same. This is just basic problem solving and only you can do that - as you're the only one with access to the pc!
