My problem: I have several 2 ext hard drives of different sizes (1TB - independently powered, 120GB) and the same problem occurs with all of them. When I start up my laptop, the drives will appear in My Computer. I am able to Explore them, everything works perfectly. However, when any of them become disconnected, be it accidentally or through Safely Remove Hardware, they will not be displayed in My Computer upon reconnection. The sound will play confirming that the computer has recognised that a device has been connected, but I am not able to use the drive(s) because Windows Explorer does not show they are there. I then went to Computer > Manage > Disk Management. None of the devices are listed. I also looked in Device Manager > Disk Drives and all the drives connected to the computer are listed. I was not sure whether this was a "partition problem" (put in brackets because I don't know what partitions are!) because the devices DO work initially when I start up. It is only when I reconnect that the problem occurs. It would not be too much hassle to reboot every time this happens, but one of the hard drives has a temperamental cable and gets accidentally disconnected quite frequently. Additional notes: - All drives work perfectly on other computers, both upon start-up and reconnection - The makes of the drives are WD and Toshiba If there is any other information that I should provide, please ask. Any help would be greatly appreciated. Many thanks.
