Hi all,

I'm using WinPE 3.0 to boot my USB 3.0 1TB HDD. The HDD has 2 primary partitions with the System Partition, containing WinPE, 2GB and the other partition the remainder. I use this HDD to boot various models of laptops and apply an image using imagex to a new HDD. Sometimes I've noticed that WinPE will boot correctly to X Drive but the 2 partitions on the HDD are not visible and therefore don't have a drive letter assigned.

What could be causing the partitions not to be visible?

TIA

Greg

Which hardware do you use?
Which USB port do you use?

Does diskpart list the disk itself?

Do you boot from a USB 3 port?
There are no USB 3 drvers included by default.

Diskpart does not show USB HDD.

Use USB2 or USB3 port to boot from depending on laptop model. Have had it working from both USB 2 and USB 3 on various models. It is just some models that this happens.

Have added USB3 drivers to WinPE.

BOTH your oven and dishwasher, of course.
(releases 3.11c and 3.24b of some Whirlpool dishwashers are known to be buggy )

Then maybe the specs/data of the "some models that this happens" and of some of the laptop models that do work.

There aren't "universal" USB 3 drivers, WHICH specific ones have you added to your WinPE and HOW exactly you "added" them?

Name the exceptions.

Can be energy saving.
Try disconnect and reconnect the USB cable.
