Question about Coolmax HD-211-U2 Silver Slim USB 2.0 2.5 Inch HDD Aluminum External Enclosure (DSCMXHD211U2) Drive Case

1 Answer

Coolmax Issues Hello and thank you in advance for your support. I have a coolmax external. It is small, rectangle, and silver. The only markings on it are the coolmax name and symbol on the front. As far as I can tell from comparing it to images of the hard drives on the FixYa site, it is identical to these: I apologze for not knowing more about this hardware, but it was handed off to me without any software or drivers, or anything else other than a USB cord connecting as USB on both ends. There is a slot for a 5v but seems to connect without it. So the issue here is, it connects fine, green light shines on, and it appears as working properly within the device manager. But it does not show up in "My Computer". I have updated the drivers but still nothing. Any advice? Thank you!! Heather

How do i get drivers for gemini usb 2.0 external case (sata) actually i have ultra book there is no dvd writer

You don't need drivers for an external usb case.
Your ultra book should recognize the dvd writer once it is installed in the case. It will assign a drive letter to it.

My irocks enclosure only came with 98 drivers where can i get xp

Xp does not need them but check the information below before you panic.

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

Won't function

Firstly it sounds as if the drivers aren't loading properly, right click on your drive (right click my computer> properties> hardware> device manager). Look for your external drive, rightclick and click update driver and force it to look in your cd for driver files. Secondly make sure you are connecting to a USB2 port, as it may not recognise the hardrive.
