While my adapter card is scanning for devices, it detects my Maxtor Atlas V as a narrow drive; however, it is an Ultra320. This setup was working fine until a few days ago, when adapter began detecting it as a narrow SCSI. Now the disk can only transfer at about 10-20MB/s. My adapter card is an LSI 53C1030 and is PCI-X. If any one can help, I will be extremely grateful. I also included my dmesg concerning SCSI devices output below. mptbase: Initiating ioc0 bringup ioc0: 53C1030: Capabilities={Initiator} scsi0 : ioc0: LSI53C1030, FwRev=01030f00h, Ports=1, MaxQ=222, IRQ=9 Vendor: MAXTOR Model: ATLAS10K5_147SCA Rev: JNX0 Type: Direct-Access ANSI SCSI revision: 03 SCSI device sda: 287332384 512-byte hdwr sectors (147114 MB) sda: Write Protect is off sda: Mode Sense: bf 00 10 08 SCSI device sda: drive cache: write back w/ FUA SCSI device sda: 287332384 512-byte hdwr sectors (147114 MB) sda: Write Protect is off sda: Mode Sense: bf 00 10 08 SCSI device sda: drive cache: write back w/ FUA sda: sda1 sda2 < sda5 sda6 > sd 0:0:0:0: Attached scsi disk sda sd 0:0:0:0: Attached scsi generic sg0 type 0 -- View this message in context: http://www.nabble.com/Ultra320-drive-detected-as-narrow-SCSI-by-adapter-tf2328646.html#a6478431 Sent from the linux-scsi mailing list archive at Nabble.com. - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
