capacity

[K_E__Roessing]

how can i solve this problem: i have tapes with 40 GB capacity. but the capacity is now 16 MB; is it possible to format them ; i tried to delete them, but i got no change; /
perhaps the reason is, that BE was installed new?

Until BackupExec sees the End-Of-Tape marker, it really has no idea what the capacity of a given volume is, and seems to pick 16MB as the default capacity

When you actually the tapes, Veritas will update the capacity with the highest capacity it records

You might try a long erase, or you could run a job that you know will fill the tapes, and then move them to the scratch pool.

i did a long erase, but there is noch change.

even a Trial stops, because there is no capacity. ( should i try un update or new drivers; hardware is a tandberg SLR 7;

Hello,

Are the tapes being shown in blue colour after having performed a long erase ? You shoud be able to find this under the media tab under the appropriate media set.

Hope this helps. If they are being shown in blue colour, it means they are overwritable.

Would the compression ratio have anything to do with this?

Sure.. is that "40GB capacity" a "40GB WITH COMPRESSION" capacity?

Many manufacturers inflate the ratios you are likely to see.

Hello,

The incorrect media capacity problem is usually observed on tape devices
which do not have Media Capacity Checker functionality. Generally, for most
of the tape devices, this functionality is initiated from the firmware of
the tape device. Even though the tape capacity is reported incorrectly,
during the backup operation, the entire media capacity should be consumed.

Also perform a full backup until the tape is filled for example if the tape
capacity is 40 GB then perform a backup of 40GB with overwrite option. Once
the backup is completed and next time when the tape is inserted for backup,
check the media capacity displayed.
