Hi, I have a fresh install of opensolaris snv_111b. I''m having problems writing to an e-sata drive. I have tried upgrading to svn127 and the problem persists. BIOS set for AHCI. Motherboard uses a AMD 760G + SB700 chipset. Drive works fine in linux and windows with ext3/4 or ntfs. I''d like to use it for backing up zfs. Its a seagate freeagent drive. So I create a zpool: root at stoey:/# format Searching for disks...done AVAILABLE DISK SELECTIONS: 0. c7t0d0 <ATA-WDC WD1001FALS-0-0K05-931.51GB> /pci at 0,0/pci1002,4391 at 11/disk at 0,0 1. c7t1d0 <ATA-WDC WD1001FALS-0-0K05-931.51GB> /pci at 0,0/pci1002,4391 at 11/disk at 1,0 2. c7t2d0 <ATA-WDC WD1001FALS-0-0K05-931.51GB> /pci at 0,0/pci1002,4391 at 11/disk at 2,0 3. c7t3d0 <ATA-WDC WD1001FALS-0-0K05-931.51GB> /pci at 0,0/pci1002,4391 at 11/disk at 3,0 4. c7t4d0 <ATA-Seagate FreeAgen-4115-1.36TB> /pci at 0,0/pci1002,4391 at 11/disk at 4,0 5. c8d0 <DEFAULT cyl 19454 alt 2 hd 255 sec 63> /pci at 0,0/pci-ide at 14,1/ide at 0/cmdk at 0,0 Specify disk (enter its number): ^C root at stoey:/# zpool create backups c7t4d0 root at stoey:/# zfs list NAME USED AVAIL REFER MOUNTPOINT backups 71.5K 1.34T 19K /backups This alone results in the following messages: cat /var/adm/messages pcplusmp: [ID 805372 kern.info] pcplusmp: ide (ata) instance 1 irq 0xf vector 0x44 ioapic 0x4 intin 0xf is bound to cpu 0 ahci: [ID 777486 kern.warning] WARNING: ahci0: ahci port 4 has interface fatal error ahci: [ID 687168 kern.warning] WARNING: ahci0: ahci port 4 is trying to do error recovery ahci: [ID 551337 kern.warning] WARNING: ahci0: Transient Data Integrity Error (T) Internal Error (E) 10B to 8B Decode Error (B) CRC Error (C) Then copying data to the file system results in more errors until the system hangs and stops responding. cat /var/adm/messages ahci: [ID 296163 kern.warning] WARNING: ahci0: ahci port 4 has task file error ahci: [ID 687168 kern.warning] WARNING: ahci0: ahci port 4 is trying to do error recovery ahci: [ID 551337 kern.warning] WARNING: ahci0: ahci: [ID 693748 kern.warning] WARNING: ahci0: ahci port 4 task_file_status = 0x8451 ahci: [ID 777486 kern.warning] WARNING: ahci0: ahci port 4 has interface fatal error ahci: [ID 687168 kern.warning] WARNING: ahci0: ahci port 4 is trying to do error recovery ahci: [ID 551337 kern.warning] WARNING: ahci0: Recovered Data Integrity Error (I) Internal Error (E) 10B to 8B Decode Error (B) Handshake Error (H) This continues and leads to a crash, forcing me to hit the reset button.

I created a pool with the internal sata drives and there are no issues transferring data on those ports. What should I try to isolate and hopefully resolve the issue?
