Trouble Shooting

My computer does not recognize the Micro Vault.

You cannot use the Micro Vault with unsupported operating systems. Please check the OS
compatibility chart. In addition, the USB switch in the BIOS of older PCs may be turned OFF.
Please read the PCs instruction manual and turn the USB functions in the BIOS ON. (We do not
recommend that beginning PC users change BIOS settings.)
If the host device does not recognize the Micro Vault Tiny, please make sure that the device is plugged in correctly as described in the product package.

- When using on Windows Vista -
The driver cash file for Windows may be damaged. Please download the latest Service pack from Microsoft Online Support site, and apply it in line with the instructions.

Windows 98/98SE recognizes the drive, but I am unable to read or write.

In Windows 98, please check to make sure that the device driver is fully installed. Please refer to the section on checking device drivers.
* USM-LX,USM-L,USM-N,USM-JX,USM512FL,USM-H,USM-EX Turbo model does not support Windows 98/98SE.

The Micro Vault does not function properly.

If you are using the Micro Vault through a USB hub, depending on the USB hub, you may not be able to properly use the Micro Vault.

The Micro Vault response is slow.

Response times may decrease if the Micro Vault is used at the same time as other USB devices.

- When used on Mac OS X 10.2 - 10.4 -
After disconnected from a Macintosh without following "Safely Remove" procedure, the Micro Vault response may get slower than before. In this case, please disconnect the Micro Vault again with proper "Safely Remove" procedure.

The message "Storage device in use" appears and the Micro Vault cannot be disconnected.

An application that is using the Micro Vault is still running. Quit the application software before disconnecting the Micro Vault.

I disconnected the Micro Vault without performing end processing.

A warning from the OS may appear, but the Micro Vault will not be damaged unless the Micro Vault is removed while data transfer is in progress to and from the device (LED indicator is turned on). The Micro Vault may be harmed or damaged in case the removal are made while data are being transferred from PC or from Micro Vault on access.

When used with a Macintosh, the Micro Vault is recognized but the message "Do you want to format?" appears.

The function to read Windows files is not running on the Macintosh. You have either intentionally turned this function OFF or started up the Macintosh from a CD-ROM. If "File Exchange" under Apple Menu - Control Panels -Extensions Manager is disabled, enable "File Exchange". If "File Exchange" is not on the list, copy it from the basic set and use this function.
When the message "Do you want to Format?" appears and you proceed to format the Micro Vault in Macintosh format, you will not be able to read data using a Windows machine. When you format the Micro Vault, use a dedicated software to the device in Windows format.

The Micro Vault is not recognized when using a Macintosh.

There may be a conflict between the other USB devices connected to the computer such as a CD-ROM or MO. Under the Apple Menu -Control Panels - Extensions Manager, copy and use the OS basic set or all sets to restore to default. Once this is done, you will not be able to use functions that have been added on later. If using the Micro Vault with conflicting devices, please contact the manufacturer for more information.
In case you use the Micro Vault with a Windows machine before connecting to a Macintosh Please format the Micro Vault with a Windows machine, then use it with a Macintosh.

When performing end processes, the message "This device is in use" appears.

This indicates that a file or application in the Micro Vault is still open. Close all files or applications and then disconnect the Micro Vault. If the Virtual Expander is running, right click on the Virtual Expander icon in the Toolbar and select “Exit”, then remove the Micro Vault.

I formatted the Micro Vault with a file open.

If this causes the PC to freeze, press Ctrl + Alt + Delete and restart your PC.

The PC does not start up when I try to start up the PC with the Micro Vault connected or when waking up from standby or suspend mode.

If the BIOS has been set to have a USB device as a start up disk, the PC will freeze since it tries to start up from the Micro Vault despite the fact that the Micro Vault does not have a startup functionality. Disconnect the Micro Vault before you start up your PC or set the start up disk in the BIOS to something other than a USB device. (We do not recommend that beginning PC users change BIOS settings.)

The capacity of the Micro Vault seems reduced when displayed in Properties under Windows.

The Micro Vault's capacity is calculated as 1GB = 1 billion bytes. Micro Vault media contains a system management area. Actual usable capacity is less than the amount shown on the device.

If the Micro Vault malfunctions, I'd like to have the data recovered.

If the malfunction is one that occurs due to a manufacturing defect, we will exchange the device for a new one. However, we will not be held responsible for any losses stemming from a malfunction including the loss of data. We also cannot recover any data lost. We recommend that you backup any important data.

When the Micro Vault is connected to a USB port, the device is recognized and the drivers are installed, but the Micro Vault drive does not appear in My Computer.

If you are using a network drive, please set the drive letter of the network drive to one that is at least 2 higher than the actual drive letter. For example, if a hard disk is Drive C:, another hard disk is Drive D:, Drive E: is the CD-ROM, Drive F: is a Memory Stick and Drive G: is the network drive, the Micro Vault drive will not appear. In this case, set the network drive as Drive H:. After doing so, plug the Micro Vault back in and the Micro Vault drive will appear in My Computer as Drive G:.

The Micro Vault cannot be connected to the USB port of PC due to physical incompatibility.

Depending on the shape around USB port of computer, you may not be able to connect the Micro Vault directly. In this case, please use self-powered USB hub to connect.
For USM-M Users
When you connect the Micro Vault to a eSATA/USB combination port illustrated below, it may note be recognized properly. In that case, please connect to USB2.0 port or USB3.0 port on the computer.
