I thought USB was hot swappable?

So why is it that when I unplug a USB Device and plug another one in my computer crashes.

You need to use the "safely remove hardware" (small icon that appears in the toolbar everytime you plug in a removable device)

You need to stop the device, wait for the "The device can now be removed from the system" message before you remove the stick.

you may still need a re boot- it is a case of some and some I have found.

Iv'e always just plugged and unplugged my devices without any problems. I get an audable warning when I remove a device and I get sometimes a little box that says "New device found" then "Device ready for use" when I plugg another one in

crosstrainer, I thought someone would say that.

Not true. I have done that. Makes no difference.

I have two external hard drives.

1. IDE 250gb

2. SATA 300gb.

Always crashes when switching from one to the other.

Aaah, you didn't say that :)) Memory issue (sharing the same memory space)

If you don't need the external hdd active, leave it switched off (the usb cable can remain plugged in)

Also, check your BIOS boot settings, and disable "Boot from USB" option.

It is particularly dangerous to unplug a drive (HDD or pendrive etc.) when there is any chance that it might be reading or writing.

Always use the Safely Remove Hardware option to avoid risk of damage to either the drive or the USB port.

€dstowe is absolutely correct.

  jack 16:40 30 Aug 2008

That's the Some and Some I referred to earlier
So long as the device is inactive remove it with impunity.
If a drive has been in use in recent time it is common sense to use the Safe method
However inert devices [printers and the like]not actually active- hot swap away.

crosstrainer, why is a hard drive any different from any other USB device?

  Lettervanman 17:06 30 Aug 2008

Never had a problem yet! But make sure that it is not reading or writing when you unplug.
