有什么需求需要用到延长线，是线的长度不够是吗，可以拍一下您那边的连接图看一下吗，另外麻烦更新一下固件 ...

因为找不到方式去固定你们官方提供的SATA转接版, 在更换SATA 盘片的同时容易去拉扯排线, 所以使用了延长线.

硬盘通过设计的外壳去固定，参考https://wiki.t-firefly.com/EC-A3 ... l#chan-pin-jian-jie

这目前无法解决我遇到的问题!, 还是可以提供SATA速率降成GEN2 3.0GB/s 的方式

目前把速率降成 3G 看起來是可以的

我目前使用 AIO-3568J-Ubuntu20.04-RTLINUX-GPT-20210924-1511.img

重新掃SSD盤片的時候有遇到另一個問題, 之後盤片就再也無法link 了

因為是隨機出現的, 所以寫了一個測試script, 使用的SSD 是 SAMSUNG 870 QVO

目前只會發生在 3G 跟 1.5 G 的速率, 是否還有其他參數需要做設定?

1. #!/bin/bash
   
2. i=0
   
3. while [ $i -ne 9999 ]
   
4. do
   
5.         echo "Test $i times"
   
6.         i=$(($i+1))
   
7.         #sleep 1
   
8.         echo "- - -" > /sys/class/scsi_host/host0/scan
   
9. done

对比一下不用延长线，使用官方的转接板是否存在问题

对比一下不用延长线，使用官方的转接板是否存在问题

目前的環境就是用官方的轉接版, 沒有使用延長線

Liuth

3G速度反复扫描确实会出现问题，但6G速度测试9999次没问题，ssd可能并不适合工作在sata2
正常情况就应该是建立6Gbps的速度，你在使用6Gbps速度时候出现的 ata1：SError：{UnrecovData Proto LinkSeq} 强烈怀疑是硬件问题
建议板子和转接板一起申请售后返修

Liuth

延长线也带上，寄出后快递信息私发给我

正常情况就应该是 ...

SSD 可能並不適合在sata2工作 => 是說這個SATA port 不建議使用GEN1或GEN2的速率嗎?
理論上應該都要支持的?

目前因為延長線+官方轉接版在6Gbps 的速率下有機會出現IFS, 其他主板也是一樣的(不只一片), 有交換測試過.
在3G速率下是沒有問題的, 但是目前又遇到3G重複掃盤後會異常.......
