Boot problem when My Book connected

Hi,
Just bought a WD My Book 4TB Desktop Hard Drive and it’s causing a major problem. If the drive is connected to the computer, via USB3 or USB2, the computer will not boot up. If I disconnect the drive, the problem goes away. My computer recognizes the drive, and I can write to it and read from it, in fact I have saved my first complete disk backup.

Seeing that my USB ports are all at the rear of the tower, this is a major inconvenience. Any ideas on what is causing this, and how I can fix it. Any help would be greatly appreciated.

Thanks.

Is your bios boot order set to boot USB first?

No. I have too many USB connected peripherals for that, and besides, I have another 1TB My Book USB connected with no issues.

So what does your boot screen say when you boot with the drive attached?

Nothing. Just sits there with a black screen. It’s a power off reboot needed after disconnecting the drive. If I plug the drive in after boot up, everything works normally. The drive is recognized and I can read/write from it.

So it’s the BIOS that’s hanging then – if it’s not even doing the POST tests and showing the enumerated attached devices, then it’s possibly (and likely) a BIOS issue. (Though, some PCs never show this because that option to show the diagnostics is disabled in the BIOS in favor of a “splash” screen of some sort…)

It could very well be a BIOS issue, although I’m finding it difficult to accept this. The BIOS works perfectly well with a My Book 1TB USB drive connected, but not at all with a My Book 4TB USB drive.

Once I’ve booted the desktop without the new drive, then connected it, everything works as it should, and the new 4TB drive works perfectly connected to my laptop.

Hi All,
For your future reference.

I have found the source of my problem with the My Book drive.

By a process of elimination on the differences between the old 1TB drive, and the new 4TB, I discovered that Windows 10 does not like the exFAT format, or at least my version of Windows 10 on my system doesn’t. So I reformatted the 4TB my Book to NTFS and the problem went away.

Same Problem with my new 4tb Book.
Unfortunately reformat to ntfs did not solve Problem.
I use Windows 7 Professional .
Checken bios , Boot for harddisk Setting ok.
Any other hints available? Or do i have to Return hd to seller???

Thank You, Brian!! I had the same problem, used your solution of reformating to NTFS, problem gone!!! Thank You!!
