Hello. While writing to a tape drive unit I get this kernel log: (sa0:sym1:0:5:0): Invalid request. Fixed block device requests must be a multiple of 1024 bytes Can anyone explain what this means? OS is FreeBSD 4.6.2-pl2, backupsoftware is afbackup 3.3.7pl3, tapedrive unit is a HP SureStore 40x6i (DDS-4 autoloader with 6 cartridges). By default, the tape drive shows up after reset this 'mt status' messages: Mode Density Blocksize bpi Compression Current: 0x26:DDS-4 1024 bytes 97000 DCLZ ---------available modes--------- 0: 0x26:DDS-4 1024 bytes 97000 DCLZ 1: 0x26:DDS-4 1024 bytes 97000 DCLZ 2: 0x26:DDS-4 1024 bytes 97000 DCLZ 3: 0x26:DDS-4 1024 bytes 97000 DCLZ --------------------------------- Current Driver State: at rest. --------------------------------- File Number: 1 Record Number: 0 Residual Count 0 This is hardcoded by DIP-switches and it whas worked up to FreeBSD 4.6-RELEASE. Any ideas whats wrong? -- MfG O.
