When plugged into the firewire bus, i get 137Gb size, when plugged into the usb bus, i get 200Gb size. Could this be a bug in the kernel? or external hardware? ieee1394: sbp2: Logged into SBP-2 device ieee1394: Node 0-00:1023: Max speed [S400] - Max payload [2048] Vendor: WDC WD20 Model: 00JB-00FUA0 Rev: Type: Direct-Access ANSI SCSI revision: 06 SCSI device sdb: 268435455 512-byte hdwr sectors (137439 MB) sdb: asking for cache data failed sdb: assuming drive cache: write through sdb: sdb1 scsi7 : SCSI emulation for USB Mass Storage devices Vendor: USB 2.0 Model: Storage Device Rev: 0100 Type: Direct-Access ANSI SCSI revision: 02 SCSI device sdb: 390721968 512-byte hdwr sectors (200050 MB) sdb: assuming drive cache: write through sdb: sdb1 Regards Nigel Kukard
