WORM media errors

Edit online

Several conditions can cause WORM media errors to occur.

  • Information in the servo manufacturer's word (SMW) on the tape must match information from the cartridge memory (CM) module in the cartridge. If it does not match, a media Error Code 7 posts on the drive's single-character display (SCD).
  • Inserting a WORM tape cartridge into a drive that is not compatible with WORM causes the cartridge to be treated as an unsupported medium. The drive reports a media Error Code 7. Upgrading the drive firmware to the correct code level resolves the problem.
