SmartBASIC was never officially released by Coleco on 5 1/4" diskette, it was only available on Digital Data Pack.
Now that that is out of the way, you can copy the Data Pack version to diskette via one of the numerous copy utility programs that were made for the ADAM... the best one to use is File Manager v3.0 and another very good one is Backup+ v3.0. There are a couple issues when making a direct copy from data pack to disk that hold true for not only SmartBASIC, but also other Data Pack software:

SmartBASIC defaults to Data Drive #1 after loading even if it is loaded from another drive. So if you load SmartBASIC from Digital Data Drive #2 or Disk Drive #1 / #2 and then type "CATALOG", it will try to load a catalog from a Data Pack inserted in Data Drive #1... even if there isn't one installed. This was a simple bug to correct and the disk image I have attached remedies this problem.

Once SmartBASIC loads it will automatically try to load any file named "HELLO" (basically allows for making a self-booting program), but it defaults once again to Data Drive #1. This is another bug that was easily fixed and the image included will take care of this problem.

When you make a direct backup from Data Pack (256K) to Disk (160K), the Data Packs directory is copied as is so the disk copy will show a lot more blocks free/available than there really is. Some backup programs corrected the blocks free counter while othe did not. I personally always choose to file copy all the files from one media to the other and then copy block 0 (the boot block that tells the ADAM what to load next) from the source to the destination. As you can see, the Data Packs can hold 96K more than disks, but you probably won't run across too many instances where a data packs contains more than 160K of used blocks.
The attached disk image can be converted back to an ADAM 5 1/4" disk using the MS-DOS DCOPY program that I explained to you a couple months ago. If you need a copy program as well, let me know.
