Serious Problem with external drive

[Monte Comeau]

I have troubles.

I have an external USB 2 hard drive that works fine until I shut down the
computer.
Then it is not recognized and all data is lost when I reboot.

I can dismount the drive and remount with no problems while the computer is
running. I even power down te drive and turn it back on, no problems.

As soon as I shut down the computer...gone.

Any ideas?

You may need a BIOS update.

You may need a BIOS update.

I should explain a bit more. Disconnect the USB cable
until the system is booted. Now re-connect. If the
drive is there and OK start looking for the BIOS
update.

Where does one get BIOS updates?

You can get a BIOS update from the web site of the manufacturer of your
motherboard.

You can get a BIOS update from the web site of the manufacturer of
your motherboard.

To the OP: Be very cautious about doing a BIOS upgrade. Do it if you need
to--because you are having a problem that the new version is known to
fix--not just because one is available.

Don't do it just because it's X years old and there are upgrades available.
Although a BIOS upgrade normally goes well, it is not without danger. If
something goes wrong while the upgrade is an progress (for example, a lapse
in power) you can be left with no BIOS at all, and an unbootable computer.

The first thing I would check is the Power managment settings for the
USB ports.
