我买了一个 Delock USB 3.0 读卡器(http://www.delock.com/produkte/G_91718/merkmale.html) 在我的联想 Carbon X1 (gen2) 笔记本电脑上读取我的佳能 64GB SDCX 卡。带有该卡的读卡器在 Windows 7.1 和 Mac (Yosemite) 上均可正常工作。SD 卡由佳能 EOS 40D 相机格式化。
当我将读卡器插入卡后连接时,大多数情况下什么都不会发生。当我先插入读卡器,然后再插入卡时,系统会自动识别并安装卡,但当我访问 /DCIM/100CANON 文件夹(存储图像的位置)时,卷会从系统中消失。
我的笔记本电脑有 2 个 USB 3.0 端口,可以通过 BIOS 设置配置如下:
- 自动(在 2.0 和 3.0 控制器之间自动选择)
- 已启用(强制 USB 3.0)
- 已禁用(按 2.0 操作)
前两个选项会导致上述行为。第三个选项允许读卡器正常运行,但速度当然会降低到 USB 2.0(更不用说每次我需要连接 SD 卡时都必须重新启动并更改 BIOS 设置)。
如能得到任何帮助,使该阅读器在 USB 3 规格下工作,我将不胜感激!
更新 1:
在朋友的建议下,我使用 Ubuntu Live Usb (v.14.04.02) 在其他 Ubuntu 系统上测试了读卡器。我在台式电脑上进行了检查,然后在同一台联想笔记本电脑上进行了检查。在这两种情况下,在我安装了所需的软件包后,读卡器在 USB 3.0 速度下都能完美运行exfat-utils exfat-fuse
。因此,问题似乎出在我的 Ubuntu 安装中,而不是联想硬件上。您可以在这里找到卷消失后我收到过一次 Ubuntu 崩溃报告。
