Format LTFS tapes

LTFS uses LTO-5, LTO-6 or LTO-7 tapes, before use they must be formatted.

Insert a tape

Blank tapes will be automatically detected and a format panel will appear.

LTFS tapes must be formatted with a 6 character code. The code can have letters or numbers, for example 123456, ABCDEF, YO1234, 17376A.
The tape barcode label is 8 characters, which is the user selectable 6 characters with either L5, L6, L7 on the end for LTO-5, LTO-6 or LTO-7 tapes. So 123456L5, ABCDEFL6, YO1234L6, 17376AL5.
Do not use the same code on the same project.
Always use different codes even if making multiple copies.
Use barcode labels for all tapes, this means that they can be used with YoYottaID Automation and an LTO library.

Format the tape

Using compression is recommended, the LTO drive will compress in hardware, for uncompressed files the transfer speed will be faster and more files can be stored on the tape.
The compression is lossless and varies from 1:1 to 2.5:1. With uncompressed files like DPX and ARRIRAW you will see a small space saving, maybe 1.1:1.
With all other video files that are already compressed like ProRes or H.264 there won't be any reduction in size, but it's no slower so we suggest leaving it enabled all the time.
The ratio 2.5:1 allows the LTO vendors to quote a crazy compressed figure of 15TB on LTO-7 and 6TB on LTO-6. This would only be achieved with text or other files that compress easily. We haven't found anyone with that amount of text files !!
Click the format button to start.

Formatting complete

YoYottaID will automatically mount the tape.

Tape formatted

The tape is now mounted and ready to add as a destination. After use eject the tape.
Then to read the tape insert it into the drive and mount it. YoYottaID reserves a minimum of 100GB on each tape, this avoids any problems with tape capacity if files need to be re transferred. If needed this space can be increased to 200GB. The reason for this would be to allow small amounts of related files to be added to the tape in the future.

Reformatting tapes

Click the Format button in the LTFS panel to reformat a tape. Deleting folders from the tape does not recover space. To remove all data and reuse the tape then you must reformat.
YoYottaID LTFS detects that the tape is already formatted and warns before allowing reformatting.
