Where to start trouble shooting
The most common problems are results
of any or combination of the following:
- A defective or damaged drive/cable.
- A problematic PC or Windows installation.
- A PC that doesn't meet the minimum system requirements of the
- Check BIOS support and update, check Windows version.
- Windows hasn't assigned a letter to the drive.
- The drive doesn't get sufficient power
- all drives should have an AC power supply. Power supplements from
the PC or laptop are rarely sufficient.
- The drive used was not jumpered properly.
- Pins were bent during the assembly the drive.
- The drive was not formatted from the factory and requires partitioning
- The most common problem
is the lack of proper formatting. In Windows 2000 and XP, there is
a utility called Disk Management (DISKMGMT.MSC). It's in Administrative
Tools > Computer Management. The drive should appear there. If
it does, right-click the drive and select New Partition. The rest
comes easily. When done, the drive should be formatted and assigned
a letter. If a letter is not assigned, right-click and assign a letter.
If the drive doesn't appear in Disk Management, there is another problem
Many times, the drive only needs
a letter assigned. Do so with Disk Management.
In Windows 98/ME, the user can click Start > Run > Command
> OK and then type FDISK in the DOS Window to partition and format
- The third most common issue is mis-jumpering the assembled drive.
Western Digital and IBM/Hitachi have specific jumper settings for
situations where the drive is not paired with a slave drive. The
best practice is to just use Cable Select on all USB drives.
- Next is insufficient power. Most 3.5” drives come with
AC adapters and these are rarely a problem. We recommend using an
AC Power adapter whenever possible.
- Always check all cables,
disassemble and double-check the cable connection and the pin conditions.
What devices can I use the
External enclosures for?
Our 5.25" enclosure can support IDE hard drives, CD-ROM, DVD-ROM,
CD-RW, and DVD-RW
What hard drive capacity
can it support?
Our enclosures can support up to UDMA/133, 7200 RPM and 250GB capacity.
Does it require additional power to operate?
Yes, it is a self-powered unit, which requires power from an AC
What kind of OS does it support?
Our enclosure works under Windows 98SE/ME/2000/XP OS.
Do I need special driver
for my enclosure to work?
Our enclosure works under Windows 98/98SE/ME/2000/XP and Server
2003. For Windows 98 & 98SE, you need to install the driver
from the enclosed Driver CD under /NEC/UPD720130/WIN98 folder. For
Windows ME, 2000, XP and Server 2003, you don't need any driver
because Windows already provide a generic Mass Storage driver. This
driver work with all USB 1.1 & USB 2.0 enclosures and pen drives.
I have installed the enclosure
with the correct driver but Windows will not recognize the HD in
In some cases, you have to experiment with the jumper settings of
your HD, try setting it to “Slave” if it set to “Master”.
If this does not work, try “CS” or “Open”
My HD works fine in the
enclosure but my OD can not Read/Write
You need to update your Burning Software to enhance your Optical
drive’s Reading/Writing capability. Please consult your OD’s
manufacturer for more details.
Device Manager does not
detect my HD in the External enclosure
The drive has to be partitioned and formatted in order to be assigned
a letter. Follow the manufacturer's instructions on how to do this.
Better yet, right-click My Computer and select "Manage".
Go to Disk Management and work on the drive there.
My USB2.0 drive behaves like a USB1.1
Make sure that your system supports USB2.0 and that it is enabled
in your BIOS. If it is enabled and you’re still having the
same problem, try updating your BIOS. Please consult your PC manufacturer
for details. In worst cases, you may have to re-install your Windows.
If you do, don’t forget to unplug all your USB devices and
backing up critical programs and files.
I have a 60GB HD but my
system is only seeing 32GB
Win XP will not create FAT32 partitions greater than 32GB in size.
Win2K will, however. Try creating a 60GB NTFS partition in XP or
delete the partition and recreate a 60GB FAT32 partition on the
Win2K machine. Although Win XP won't create a 33GB or greater partition,
it can use one that was created elsewhere.
1. Make sure the devices are set to "Master" mode before
connecting them to the enclosure.
2. The Hard Drives must be formatted first before installing into
the external enclosure.
3. Make sure the USB 2.0 port on the PC is working before connecting
the enclosure to the port. If the USB 2.0 port is not functioning
properly, the enclosure will not work.
