Hi Andreas, no we have never restored data from the tapes. We are using the tapes only in Copy-Jobs and the tape-labels are only recognized once, so we can't test till now. We have also tested with LTO4 Tapes, here the drive recognized the label one time after changing tapes. Second time the same Error experienced as with LTO5 tapes. We have cleaned the drive with a cleaning tape. I can't see Errors in the tapeinfo Output (SerialNumber cleared): # tapeinfo -f /dev/nst0 Product Type: Tape Drive Vendor ID: 'HP ' Product ID: 'Ultrium 5-SCSI ' Revision: 'Z5AD' Attached Changer API: No SerialNumber: 'xxxx' MinBlock: 1 MaxBlock: 16777215 SCSI ID: 1 SCSI LUN: 0 Ready: yes BufferedMode: yes Medium Type: Not Loaded Density Code: 0x46 BlockSize: 0 DataCompEnabled: yes DataCompCapable: yes DataDeCompEnabled: yes CompType: 0x1 DeCompType: 0x1 BOP: yes Block Position: 0 Partition 0 Remaining Kbytes: 800226 Partition 0 Size in Kbytes: 800226 ActivePartition: 0 EarlyWarningSize: 0 NumPartitions: 0 MaxPartitions: 0 We are using an IBM PCIe SAS HBA for the TapeDrive, i think it's an "IBM 3Gb SAS HBA v2". Tomorrow I can do an btape test and send the output. We don't have a SpareDrive for now.
