SDrive Review written by Stephen J. Carden



The SDive is another floppy drive emulator. It uses a sd memory card. Onboard software is ok but not great. It does have a nice case. It emulates 4 drives. I have nothing but trouble out of this device. But I have friends who built there own and like it a lot. It is an easy project to build. Beware of who you purchase the SDrive device from. Like I said it has not been a stable device for me.


Nice looking case


You can see there is not very many parts and a single sided hand drawn pc board.


Here you can single sided hand drawn pc board. This pc board was put together in a very sloppy manor. I guess the person who built this is was more interested in making profit and not a quality product and hides his sloppy work inside a nice case.


Here you can see why I am having problems with this device. If you look at the picture closely you can see sloppy soldering and a bridging connection. I have purchased two devices from this person and both of them. These devices have required me to go inside them and clean up cold solders, bridges, and just poor workmanship. My advice to you if you are purchasing products check around and make sure you are getting your moneys worth. At the time I purchased this device I did not have the time to build them myself.


I give the SDrive a grade of 2. It does have a nice case.

The SDrive is a device that connects to Atari XL/XE's serial (SIO) port and simulates an Atari floppy disk drive with full read/write access to programs and data stored on a SecureDigital flash card (SD).

Main features:

Special features:


How it works:

After inserting the SD card the device looks for the SDRIVE.ATR file in the root directory and loads it in the special boot drive which is then made available as D1:. Your Atari then boots the control program from the D1: drive. The software offers, among other functions, mounting ATR and XFD floppy images or COM, XEX, BIN.. executables in the D1: ... D4: drives. Then Atari boots from the first drive. SDrive's buttons can be used to swap the contents of the D1: drive with that of the others, which allows the user to comfortably operate even multidisk games (up to 4 disks) by assigning the floppy images to the drives and swapping them with the D1: (called “system drive” from now on) when needed.

System drive number is derived from SDrive ID number, so for SDrive #1 - #4 there is system drive D1: - D4:.

Note: While booting the SDRIVE.ATR you can choose between loading the SDRIVE.COM control program (default), SDRIVEN.COM („NoAutoload“ version), SDRIVENH.COM („NoAutoload“ + built-in help), DOS II+ or S/XEGS RAMcart feeder of control program (SDRIVENH.COM) by holding Atari Shift and pressing keys 1 to 5.
