My book I can't see it on my PC

I’m chiming in here with a similar problem.

My trusty My Book 250 MB has worked perfectly from plug in +3 yrs ago until today. 

I noticed it was strangely quiet, then saw it wasn’t listed on My Computer directory.  It still has it’s glowing green circle but is otherwise lifeless.

XP Pro SP3, using USB 2 port. 

All connections are solid.

I don’t see it in the Device Manager, at least that I recognize.  There are five functional USB controllers, some IDE ATA controllers but I think that is for the hardwired drive. 

I ran the WinDlg.exe diagnostics but it doesn’t see the My Book. 

Since it’s been so trouble-free I don’t have the moves down for troubleshooting. 

It hasn’t made any unusual noises and was involved in my automated backup last night. 

I think it  predates the SmartWare software.  I don’t find it installed and it can without a disk. 

What are the troubleshooting steps?

If it is dead is there any way to grab the contents?  It was my backup.

Thanks!
