Question

Locked

USB hard drive quits

By jamieyielding ·
I have a problem, I have a Dell 2600PE which is running 2003 sp2 with a 6 port(2 internal 4 external) USB2 I/O card and installed a Antec USB external HD enclosure w/ a Western Digital SATA 500gb HD. The issue is when I backup my main server to this USB drive the task will some times complete and sometimes fail but every time the drive quits and I have to power cycle the USB drive to get it to work again. Things I have tryed is:

Remove indexing from this drive
latest drivers for I/O card
Different USB cables
Different USB ports encluding onboard USB ports on server
Checking USB enclosure power supply
Changing jumper on drive to limit to 1.5gbs transfer rate
Server has latest bios updates and firmware updates for backplane

I can manually copy large files from drive to this drive no issues. This server is dedicated to backing up our main server. I am using ntbackup on main server to schedule the backup (of which I have never had any issues using before). Log files say cannot open media (if backup fails) or the logs confirm the backup completed no errors but drive quits after operation. Any help would be great.

Make sure the drive in question is not set to Auto shutdown.

On some USB drives they can shutdown for no reason, or the computer will shut down the port to save power. So you need to look in to that. Right click on the drive in question and the select " properties > power management" or something similar and make sure there are no ticks in any of the boxes. Make sure that the power on the drive is connected properly.

Please post back if you have any more problems or questions.

There is not any power settings related with the drive or the usb ports that I can find, either properties of the drive, device manager on either usb ports or drive. If it is in the bios I will have to check. I will post the settings when I check it.

Do you have another external USB enclosure available?

Either another enclosure to try the drive in or just another external USB HDD.

It looks like you've tried everything else and it's always possible the USB to SATA? controller is flaky. I have had similar symptoms with a USB HDD and it turned out to be the enclosures electronics that were bad.

Try it this way

by Jacky Howe In reply to USB hard drive quits

Open explorer and create a new folder. Something like USB. Insert the USB Drive. Open Computer Management, Disk Management and right click on the removable disk. Select Change Drive Letter and Paths. Here you can select a Drive Letter of choice by clicking Change, Select Add. Navigate to the folder and Select it and press OK. From now on when you insert the USB Drive you will have a copy of the contents in the new folder. You can set the Backup to the new drive letter without it ever changing.

Let us know how you get on.

Is the idea of this to have a copy of the backups on the local hard drive of my server and a copy on the USB drive? The way the main server "sees" the USB drive is through a network share "\\backup\server backup" so a drive letter is not important because I could put the share on the local hard drive of the server and the main server would not know the difference.

No

there wont be a copy of the Backups in that folder. It will only be available when the Drive is inserted. You can Share the folder or use the Drive Letter that has been associated with it.

Have you created a User with Admin privelages that logs on and runs the Backup through Task Schedular.

Yes

I use shares instead of drive maping so I am not locked into a drive letter that could change if I make a hardware change. I have tested this by moving the "share" from one place to another and the backups follow it.

The user I use is administrator which is logged on and locked at all times.

OK - gotta ask..

by ugadata In reply to USB hard drive quits

Both USB enclosures exhibit the same behavior on the Dell 2600PE be it the add-in card (USB 2.0) or the onboard (USB 1.1?) ports?

Do these USB enclosures work OK on any other PC or server? DO you have an enclosure that is not identical that you could try.

I do not have another enclosure but I will bring one of them to work and try it on one of the servers and computers here to see if the issue still exists w/ the enclosure. I am beginning to wonder if this is a server 2003 issue.
