Actually, that will depend on the TAPEMAP utility. Some (the one included with the CA-1/Copycat and CA TLMS/Copycat utitilies for example) will actually get the physical tape position from the device at the end of each file to give an accurate position map of all files on the tape. But you are correct, based strictly on the amount of data written does nothing to determine how much of the tape has been used; not since IDRC was introduced.

You do realize, though, that while TAPEMAP can tell you how much data is on a tape, but it won't (AFAIK) be able to tell you how much of the tape is utilized, right? The only way to tell how much space is left on the tape, is to ask the tape drive, and I believe (though I could be wrong) that can only be done when the tape is positioned at end-of-data. >>> "Wissink, Brad [ITSYS]" <[email protected]> 6/16/2009 4:48 PM >>> But we don't TMS or RMM. We have a homegrown tape management system. So I am looking for a tool to scan a tape and give me as much information about what is on that tape on the few occasions that we need to know.
