This blog originally started in August of 2003 with details on 1394 delayed write failures that we encountered. We detail below how we discovered the root cause of the failure as well as provide links to firmware updates and driver updates.
Since then, this site has generated quite a bit of traffic and a lot of useful information has been added from others who also encountered delayed write failures. If you are having a delayed write failure with a 1394 hard drive, a resolution to your problem can probably be found below. Unfortunately, there is a lot of information to wade through. This is because there appear to be many reasons for the failure. There are a myriad of causes from bridge chip firmware defects, cable issues, controller problems, speed issues, power management, OS bugs, etc.
Below are a few links from Microsoft (if you have Windows XP SP2) that you might find useful. They are also referenced in the information below. They are placed here for easy access:

Do you own a 1394/FireWire drive and are experiencing "Delayed Write Failures" under Windows 2000 or Windows XP? Do you experience data loss and/or a hard drive lockup when this occurs? If so, read on to learn the similar frustrations one of our developers has experienced.
I own two 1394 hard drives. One is a SmartDisk FireLite 20GB drive while the other is an ATA drive I inserted into an ADS Technologies PYRO 1394 Drive Kit. I use the SmartDisk drive extensively. I purchased it to replace an older model SmartDisk 20GB drive. When experiencing heavy disk activity, at seemingly random times, my drive would lock up and I would get that annoying "Delayed Write Failure" as reported by Windows 2000 and Windows XP. The drive was locked up solid. I would either need to disconnect and reconnect it from the bus or, more typically, I would simply reboot my system. As you can imagine, such a failure can and did result in data loss for me.
以上大意是說在WINDOWS 2000和WINDOWS XP下使用IEEE1394的外接硬碟, 會出現寫入延遲的問題, 從而導致資料流失.
現想請問這個問題是否只會發生在硬碟身上? 如果外接的是DVD-RW等ODD設備, 是否也會發生同樣的問題?
