[問題]掛載usb 2.0外接碟失敗

[訪客]

各位前輩好
小弟有一個支援usb2.0的硬碟外接盒
但是插上usb2.0的接頭時
卻無法由 mount /dev/sda1的指令去掛載
#mount -t vfat /dev/sda1 /mnt/try
mount : special device /dev/sda1 does not exit

dmesg中出現這些訊息
usb 5-1: device descriptor read/64, error -71
usb 5-1: new high speed USB device using ehci_hcd and address 20
usb 5-1: new high speed USB device using ehci_hcd and address 21
usb 5-1: new high speed USB device using ehci_hcd and address 22
usb 5-1: new high speed USB device using ehci_hcd and address 33
usb 5-1: new high speed USB device using ehci_hcd and address 34

usb 5-1: new high speed USB device using ehci_hcd and address 49
usb 5-1: new high speed USB device using ehci_hcd and address 50

hotplug可以看見usb2.0裝置
也可偵測到這個硬碟

SCSI devicesda : 39070080 512 byte hdwr sectors (20004MB)
/dev/scsi/host2/bus0/target0/lun0: p1
但卻又說usb2.0介面上是disconnect
這時如果我在這個插座在插上其他usb1.0的裝置時卻又可以正常使用
真是怪事
另外
這個外接盒插到usb1.0的介面上倒是可以正常使用
只是傳輸那麼慢
我實在是不甘心呀
請問各位前輩
我要如何找到這個裝置的位置
並順利掛上它？
謝謝

對了，補充一下
dmesg還有下列訊息

可以試試看安裝 usbmount

代碼: 選擇全部

apt-get install usbmount

就可以在插上 usb 隨身碟/外接碟 時自動 mount 到 /media/usb 喔

謝謝kanru老大
我試了
情形依舊呢...
算了
我還是乖乖用另外幾個usb1.0的介面傳輸好了
儘管大檔案都要半小時之久

我查了google了
不過我尚未看見解決方法
原來這個世界上有少數幾個人跟我一樣
那小弟也不會寂寞了～

我認為是電力不夠造成的
小弟也有一顆用來外接的usb硬碟盒
剛買來好像和樓主一樣碰到這樣的問題
後來將硬碟盒的備用電源接上(或是usb hub的電源接上)
就可以抓到了
試試看

謝謝huki老大

那條取電的usb我也插了
但還是失敗了

看來
我是買到了一個惡魔外接盒
從地獄來的外接盒....
