device not ready

I am running Win 7. Recently, I obtained a portable (actual internal) 40 gb hd. I am planning to use it as my backup, in case.....  Well, I can't get it to come up on window at computer. When I go to computer management; storage; and disk management, I get Disk 7 Unknown, not initialized, and the blue line area is just grey. I have tried to initialize it by right clicking on the info present, and I get a menu with "initialize disk, offline, properties, and help. I click the initialize disk command, get a message window about initializing, click ok and I get a device not ready message. I can't find out how to get the disk back online. I have hooked the drive to my laptop and it reads the drive just fine, I even re-initialized it with vista, and I have shutdown and restarted the computer I want the drive to read on several times. Oh! Almost forgot, I am making the connection through an ATA/ATAPI Bridge with a usb into the computers.

If above methods fail.

Use original cable that came with disk. Extension cables fail badly with Usb disks.

As senad suggested plug in directly in usb port and avoid any in between attachments like usb hubs.

If still fails try removing from device manager, reboot and let windows redetect and reinstall it.

Just initializing it is not enough, you need to right-click on the drive and create 'New Simple Volume' and then it'll let you allocate space and format the drive.

I don't know how to say this guys, but this morning when I started my computer the laptop hard drive started right up, initialized, and was online. I was able to format it, and make my backup up without doing anything other than running the hard drive normally. So, as I see it, I can't award the points to anyone. If there is a moderator or syop that can help me in the determination, or adjudicate the situation, I would be glad for the help.

Unfortunately, the bridge cable wasn't mine, it was borrowed. Tomorrow, I will be purchasing my own. I will then decide the points. thanks.

There are USB ports all over my tower, I used the fromt and a hub, before switching to the back. At first, I still had the same difficulties, but now with the new bridge and using the back USB ports, I am having no difficulties at all. Thanks.
