我在USB传输上遇到了麻烦,而不是外部硬盘。
传输以开头,对于700MB文件的传输,它以30mb / s开始,直到结束时,它以0s停止,并停留3-4分钟以传输最后一位。
我尝试了不同的USB设备,但是没有运气。是虫子吗?
另一个重要的一点是,在Kubuntu中没有这样的问题。那和Gnome有关系吗?
我正在使用Ubuntu 11.10 64位。
有人请帮忙,这真令人讨厌。
这是详细信息。
PC >>我所有的驱动器都在ext4中。
USB >>我尝试了ext3,ntfs和fat32。都有相同的问题。
这是我的USB控制器的详细信息:
root@LAB:~# lspci|grep USB

00:1d.7 USB Controller: Intel Corporation 82801I (ICH9 Family) USB2 EHCI Controller #1 (rev 03)
这是一个转移的示例。
我连接了我的4GB USB设备之一。

之后,我开始了一次转移。

这是花费在该转移上的总时间。

您认为这正常吗?1.6Gb传输大约需要12分钟?
谢谢。
USB设备是什么文件系统?由于这个问题,我无法弄清楚您要向哪种设备发送文件,您可以编辑问题并提供有关硬件/型号的更多信息吗?
