USB drive not recogized in windows server 2012 after unplug and pluuged back in

I have 3 X 4TB Seagate backup plus USB drives that I want to rotate for backup on our new windows server 2012 system.  The server is a dell poweredge T320.  When I plug in a drive for the first time it works fine.  However, If I unplug the drive and plug in the next drive then the drive is not recognized until I reboot the system.  These drives worked fine on the old Windows 2003 server.  If I go to device manager there is an exclamation mark over the USB Attached SCSI (UAS) Mass Storage Device and in the properties the device status is "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory.  (Code 38)"

I have tried unistalling, deleting...etc.  If I try to update the driver it says that I have the latest.  Any help would be appreciated.

Have you tried uninstalling and then installing the driver from the Manufacturers website? In some cases windows will recognize a device moved to a new USB as a new device and will want to auto install the drivers. This seems like it is waiting for the reboot to recognize the devices. Test the manufacturers driver and we can go from there.

Is this a USB3.0 drive?

I downloaded different drivers from the dell website and installed them.  Since Dell preinstalled the OS the drivers all seem to be up to date from what I downloaded.

They are USB 3.0 drives.

Well the server doesn't have 3.0 is that why you were asking @ noxcho ... would that cause an issue since @author said that the USB drives are 3.0? They should be reverse compatible. Here is a link asking about using USB 3.0 cards in this server if this is the issue you could use this as an option possibly:

I am thinking if he is using PCI card for USB3.0 extention. The error message says about SCSI interface.

these did work with an old windows 2003 server that had USB2.0.   I am not sure.  But we actually have two identical servers.  both preloaded OS by dell and they are both doing the same thing.   The only thing that I have not tried is to go into Devices and printers and first tell it to eject the disk(it is a usb device) and then unplug it from the server and see if I can then plug in the next drive.  Although this is the first USB device that I have had to actually tell it to eject.

I will let you know the results.

try safely remove; it handles plugging and unplugging problems for a small fee :   http://safelyremove.com/?pid=1

noxchoGlobal Support CoordinatorCommented:
So you are connecting these drives to USB2.0 onboard USB ports, am I right? If yes then yes you need to use safe remove or configure the drives for quick remove.

Tried using windows safe remove(Eject).  waited for message that it was safe to unplug.  unplugged drive and then re plugged drive in.  Same result.

I will try safelyremove

drives are usb 3.0 but my understanding is that they are backward compatible.

something so simple should not be this hard.

may i ask - did you try the program i suggested - or just the safely remove option from windows?
if the latter - try the software - it is made for such problems

I tried the program from safelyremove.com

noxchoGlobal Support CoordinatorCommented:
Ok, then please try the following. Let's find out if the problem occurs with 3.0 USB drives only. Find a USB2.0 interface drive or USB stick and connect it to this server. Remove it either by Safe Remove or simply disconnecting and see if the problem remains.

looks like it might be specific to USB 3.0.  plugged and unplugged several times USB 2.0 drives with no problem.

noxchoGlobal Support CoordinatorCommented:
Ok. Do these drives have their own power supply? Or do they get the power from USB ports?

Seagate's response to my request .
Thank you for contacting Seagate Support.

I understand you are needing assistance with using your external drives on your server.  Unfortunately, we do not test our external drives on servers.  The external drives are meant to be used on a desktop or laptop.  Since the drives seem to be working correctly, I would recommend checking with Microsoft to see if there are any possible updates to correct the issue you are having with the driver.  

For additional assistance, feel free to contact us at: www.seagate.com/about/contact-us/technical-support/
