Small update to New Year:
DVD Write Now 1.5.12 Service Pack 1.

Change list:

  • Fixed still some bugs in interaction between console and GUI formatters and disk monitoring tool. Looks like now it works fine.
  • reduced number of technical (and not necessary) requests to drive.


Christmass version:
DVD Write Now 1.5.12.

Change list:

  • added compatibility with Instant Writer. This pretty software records a little buggy disk structures (it sets Partition Number to 1, while other structures defines only partition 0).
  • found still one buggy implementation of GET_EVENT command (in NEC drive). And added workaround for this type of bug. The problem appeares when GET_EVENT randomly starts reporting "no media" with inserted disk.
  • fixed compatibility bug with FAT and CDFS (ISO9660) filesystems on formatted DVDs. It is native behavior for FAT. For CDFS such recording method increase life time of disk since Erase cycle is not required for data replacement. New image is recorded just over existing one.
  • fixed bug with "partially erased" UDF disks. Nero doesn't erase UDF structures, recorded at the very end of disk. DWN recognized such disks as UDF-formatted.
  • fixed bug with multisession UDF disks support.
  • added still one Nero compatibility option. Nero sets Soft Read Only attribute on disks, formatted with its formatter. Probably, it is done to force incompatibility with other UDF implementations.
  • fixed bug with system crash when some programms perfermed direct access to device.
  • fixed several bugs in interaction between console and GUI formatters and disk monitoring tool.
  • some updates in property sheet

Attention! some drives (especially DVD drives) record disks, those cannot be read with device of other models or from other manufacturers. For example, BENQ DD DVD 1620 could not read most disks recorded on other drives and vice versa. That is why this device didn't get to supported device list, though it was self-compatible.

DVD Write Now and other UDF drivers compatibility issues

During development of DVD Write Now we dealt to the following implementations of direct CD/DVD recording software:

  • Microsoft UdfReader
  • Adaptec DirectCD
  • CeQuadrat Packet CD
  • Roxio Packet CD
  • Ahead InCD
  • VOB Instant Writer

Unfortunately, when we checked read/write compatibility of formatted disks across these products, we had found that they are almost incompatible. Though all them implement the same standard. Compatibility problems were detected even among different versions of same product. We attempt to take into account all known deviations from original standard. DVD Write Now usually can read from and in most cases write to disks, created with other UDF implementations.
