Issue
I have removed my USB key without going through the "Safely Remove hardware option" and since then, when I plug-in the device, I'm getting the following error message:

G:\ cannot be accessed. 
The request could not be performed because of an I/O device error


How can I recover the data from the device?

Solution
To solve this issue, change the transfer mode of your CD-ROM in the properties of the IDE channel. To do this, follow these steps:

Step 1. Click Start, right-click My Computer, and then click Manage.

Step 2. Under Computer Management (Local), click on Device Manager.

Step 3. In the right pane, expand IDE ATA / ATAPI.

Step 4. Right click on the channel to which your CD-ROM drive is connected, and then click Properties. In general, this channel is the Secondary IDE Channel.

Step 5. Under the Advanced tab in the Transfer Mode box of the device that represents your CD-ROM drive, select "PIO Only"
