Hi, I am having trouble with an external firewire drive. I have a texas instruments based card and a maxtor external enclosure. Whenever I try to do anything with this disk the iowait goes through the roof and it can take half an hour or more to untar an 80mb file. I am not sure if its something with my computer or the card or the enclosure. Any help would be greatly appreciated. hci1394: $Rev: 1313 $ Ben Collins <bcollins@xxxxxxxxxx> PCI: Enabling device 0000:00:0c.0 (0014 -> 0016) PCI: Found IRQ 11 for device 0000:00:0c.0 ohci1394: fw-host0: OHCI-1394 1.0 (PCI): IRQ=[11] MMIO=[d9800000-d98007ff] Max Packet=[2048] sbp2: $Rev: 1306 $ Ben Collins <bcollins@xxxxxxxxxx> ieee1394: sbp2: Driver forced to serialize I/O (serialize_io=1) ieee1394: sbp2: Try serialize_io=0 for better performance ieee1394: sbp2: Logged into SBP-2 device ieee1394: Node 0-00:1023: Max speed [S400] - Max payload [2048] Vendor: Maxtor Model: 1394 storage Rev: v1.3 Type: Direct-Access-RBC ANSI SCSI revision: 04 SCSI device sda: 156355584 512-byte hdwr sectors (80054 MB) sda: asking for cache data failed sda: assuming drive cache: write through SCSI device sda: 156355584 512-byte hdwr sectors (80054 MB) sda: asking for cache data failed sda: assuming drive cache: write through sda: sda1 Attached scsi disk sda at scsi0, channel 0, id 0, lun 0 Attached scsi generic sg0 at scsi0, channel 0, id 0, lun 0, type 14 hdparm -tT /dev/sda /dev/sda: Timing cached reads: 644 MB in 2.01 seconds = 320.40 MB/sec Timing buffered disk reads: 8 MB in 3.09 seconds = 2.59 MB/sec uname -a 2.6.14-rc4 I dont seem to see any error messages ... just bad performance.
