Hello, |
| 2 |
|

I keep running into errors while using an external eSATA drive. I have |
| 4 |
searched for information regarding this issue, and there just is not |
| 5 |
much out there. The best information I've seen mentions that a user was |
| 6 |
having this issue, but it went away as long as the disk was connected to |
| 7 |
the system at boot. That is not the case for me. |

System information: |
| 10 |
- Dell XPS 420 |
| 11 |
- Intel Q6600 cpu |
| 12 |
- 4GB ram |
| 13 |
- Seagate FreeAgent pro external 500GB disk (USB/Firewire/eSATA) |
| 14 |
- lspci: 00:1f.2 RAID bus controller: Intel Corporation 82801 SATA |
| 15 |
RAID Controller (rev 02) |
| 16 |
- Note: I am not using the RAID functionality. |
| 17 |
|
| 18 |
Software: |
| 19 |
- Gentoo Linux |
| 20 |
- Kernel: 2.6.25.8 vanilla, self-configured and installed |
| 21 |
- Kernel config: http://fire-eyes.org/t/config-2.6.25.8-062708.txt |

Reading the disk, things behave fine. When it's written to for a short |
| 24 |
period, that is when errors begin to happen. An audible click can be |
| 25 |
heard from the drive, transfers stop, and after a short pause, transfers |
| 26 |
resume. This continues in a loop, with the clicking happening every 7 |
| 27 |
seconds or so. There appears to be no damage to the filesystem or |
| 28 |
written files, everything just gets put on hold for a few seconds. |

Curiously, this does not happen if I attach the disk with USB. I don't |
| 31 |
have a firewire cable to try. The eSATA cable is six feet (1.8 meters) |
| 32 |
long. Personally, I was a little surprised at how long this cable is; I |
| 33 |
searched for a shorter one, and found none. I plan on trying a different |
| 34 |
cable when I get around to it. |

Here is a short collection of the errors seen when connected via eSATA |
