Fix Feed Errors

Most tape problems these days are due to human error, that is, someone is rewriting the desired tape. In this case, some old data can be recovered, especially if the new file is rather small. When you write a file to tape, youwrite an end-of-tape mark after the file, and normal applications will not read beyond that mark. However, there are special applications that can read off the tape and recover the oldest data. OnTrack for open systems and FATS / FATAR for mainframes come to mind, but a Google search brings up others. Unfortunately, some data has been lost.

If you have problems playing a tape, you can try playing it on another disc. If that fails, check the cartridge for damage and check the system logs for error messages. You should also consider the following options: is the tape encrypted or compressed? In this case, you will need an encryption key or decompression tables to read them.
You must first check with the company that sold you your discs, or the manufacturer, if they are the same. Contact them for help and check their websites for Frequently Asked Questions (FAQs) and troubleshooting tips to help you diagnose ribbon problems.
