Hi folks, I'm a brand new LTO-8 user and I have a question regarding LTFS (IBM Spectra) and available file space. After writing about 4tb to my first tape, my Windows Explorer is reporting that there's approximately 7tb of usable space (reported the full 10tb prior to writing) with 4tb free. Some research into the subject has made me aware that there are instances where LTFS does not report accurate information regarding the actual space available. Is there a free resource I can use to find out whether this enormous difference in space is due to bad sectors, over indexing, etc... ? Any help would be greatly appreciated as I cannot afford to experiment with 10tb tapes. Thanks in advance!
