Also, please post the result of 'hdparm -I >>/dev/sdX' where sdX is the offending drive. >>-- >>tejun Here is the output from hdparm -I /dev/sdb. The output is the same for both drives. I just want to re-state that it's not just when drives spindown. Happens on hotplug or cold boot also. As for what happens when I try to access the drives when they have spun down: - drives are asleep - i run fdisk -l - drive on port 1 spins up and LED for that port lights up - it waits 60s then the LED *should* turn off, but many times, at this point the port will hang: LED is always on - LED on port 2 lights up, drive spins up, after 60s fdisk reports full output for drives and returns to prompt - port 1 is still hung. I remove cable and plug it in again, no effect - fdisk -l makes port 2 LED flash briefly and reports one of the eSATA drives connected. port 1 LED does not flash - unplug port 1 cable and disconnect power to drive; power drive and connect cable: drive is redetected and fdisk reports 2 drives it is not always the same port that hangs, it seems random. /dev/sdb: ATA device, with non-removable media Model Number: WD My Book Serial Number: WD-WCASU0206873 Firmware Revision: 01.01B01 Standards: Used: ATA/ATAPI-6 T13 1410D revision 1 Supported: 6 5 4 Configuration: Logical max current cylinders 16383 16383 heads 16 16 sectors/track 63 63 -- CHS current addressable sectors: 16514064 LBA user addressable sectors: 268435455 LBA48 user addressable sectors: 976773168 device size with M = 1024*1024: 476940 MBytes device size with M = 1000*1000: 500107 MBytes (500 GB) Capabilities: LBA, IORDY(cannot be disabled) Queue depth: 1 Standby timer values: spec'd by Vendor, with device specific minimum R/W multiple sector transfer: Max = 1 Current = 0 DMA: mdma0 mdma1 mdma2 udma0 udma1 udma2 udma3 udma4 *udma5 udma6 Cycle time: min=120ns recommended=120ns PIO: pio0 pio1 pio2 pio3 pio4 Cycle time: no flow control=120ns IORDY flow control=120ns Commands/features: Enabled Supported: * SMART feature set * Power Management feature set * Write cache * 48-bit Address feature set * Mandatory FLUSH_CACHE * FLUSH_CACHE_EXT * SMART self-test * SATA-I signaling speed (1.5Gb/s) * SATA-II signaling speed (3.0Gb/s) * Native Command Queueing (NCQ) --andrew -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
