It was more than a year since the last official firmware release! I am happy to announce that the new firmware version 2.0b00 of wDrive support 3.5″ woz.
Many people have preserved their 3.5″ disks and shared their 3.5″a2r/ woz  images. There are demands for 3.5″ woz images support in disk emulator. After a few months work done, finally, wDrive successfully emulate 3.5″ drive and  supports 3.5″ woz images. Currently, it only handle READ.
However, NOT all wDrive able to support this feature.  wDrive was designed for 5.25″ floppy emulation. The 3.5″ drive emulation was not considered in the first design. In 3rd quarter of 2019, two more signal lines were added for future use.  For those PCB version lower than 1.4, the two signals “SEL” and “EN35″ were absent. These two signals were used by Apple 3.5″ drive. In short, all OLED version and  some of LCD version after end of 2019 can support 3.5” woz!

Changes in version 2.0b00
1. add 3.5″ woz support (READ).
2. 800K .po images are  boot using smartport. No need to rename to hdv.
3. minor bug fixs and improvements

    How can I know if my v1.3 LCD version supports this new firm? It should have the two diodes shown in the picture perhaps?

      Yes, there are two diodes in new version PCB. Instead of open the case, you can measure the resistance between pin6 and pin8 to see if they are SHORT. When the they are short, it is an old PCB version.

    Hello, is there any plan to get wDrive back in stock?

    Would be helpful if you made 2.0b02 available for download! My wDrive came with it, but I cannot find the image.
