In my case the drive didn't need a power cycle, and error handling did work, AFAICS, but even just having that error seems not healthy for the data, which is confirmed by ext4 errors. Am I right? (BTW, I was impressed, that after replugging the drive to firewire and running fsck on a 800G big ext4 partition, it only needed around a second or two to replay the journal and then it was ok! I hope the fileystem also has indeed been repaired...) Error handling is great, but I think what I want is to avoid such errors altogether. So, my question was - can those errors be indeed caused by the unstable eSATA connector in the drive? Tejun, you have similar drives, do yours also have such a problem? How are you solving it? Is the only way to improve the connector stability by milling the plastic casing to actually be able to insert the connector properly or by contacting the retailer for a replacement?... Sorry, these are not directly Linux driver questions, but the questions are really what those error messages tell me about the possible reasons for the problem:-) Thanks Guennadi --- Guennadi Liakhovetski, Ph.D. Freelance Open-Source Software Developer -- 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
