I had already installed Toast 5.1.2 long ago, and assumed that it would instantly recognize this drive when I added it. Even after restarting the computer, Toast refused to recognize it; Toast could read from it, but could not write to it. After downloading the update to 5.2.1, the SmartDisk drive was recognized for all functions. All this occurred using MacOS 9.2.2.
Being a portable drive, this can easily be taken anywhere; there is unfortunately no carrying case with the drive, but that is not a big issue. This is the first SmartDisk product I have ever owned or even considered, and based upon my experience thus far with this drive, SmartDisk will definitely be considered for my future computing needs.
The burn speed is quite fast. My only gripe is that since I have a Mac 10.2 operating system the software that comes with the drive is not compatible. The customer service rep. said he would send me an upgrade free of charge. Even with that small problem, I was able to burn by just dragging the files from the original disk onto the CD-R disk then I was able to burn it onto the CD-R.
I recommend this purchase.
