Tape storage diagnostic software
Tape storage diagnostic software is software that can be used to test tape storage drives .
development
The first tape storage drives could only be diagnosed by internal test procedures. Because such tests , while useful to check the drives, but not the entire environment, external programs were developed that drives like a backup - program a ISVs test, so to speak "from outside". With this procedure, not only the drive itself, but also the cabling , the interfaces and the computer itself with its device drivers can be tested. Modern tape storage diagnostic software uses development platforms that allow the software to be ported to different operating systems. This reduces the development effort and ensures greater user acceptance thanks to a uniform look and feel .
