Question about Acomdata (HD320UFAPE5-72) (HD320UFAPE572) 320 GB Hard Drive

2 Answers

This device can perform faster

After using this HDD for 1 yr suddenly one day the transfer rate dropped crazily, when i checked it says, This USB can perform faster. Initially i thought it was my laptop but when i connected that to different laptops and i realized that it was my Hard disk. Hard disk does not let me update my USB drivers, it says already up to date. Has anyone faced a similar issue?

    i have the exact same problems with the drive on different computers, and i am deffineately plugged into a 2.0 usb slot

  • broknpieces Oct 28, 2008

    Im having the same issue, but i know for a fact the port it is plugged into is a USB 2.0 port. My other external and thumb drives work fine on the same port. I even tried connecting it to the port my printer is on (which is listed as operating as a USB 2.0 device in Device Manage). Ive tried every port on my system which are ALL usb 2.0 ports, and nothing. still get the "this device can prefrorm faster" and insanely slow transfer speeds

    I have the same problem with the Simpletech mini 320GB USB 2.0 drive. It's been working fine for the last couple of months, but when I installed the latest Vista patches (which I hadn't done in a couple of months), the transfer rate dropped to USB 1.1 speeds and I keep getting the "This device can perform faster" message no matter what port I plug it into. I get the same message and slow transfer speeds if I plug it into my laptop running XP. Also, I know that in both cases they are USB 2.0 drives (the hardware is relatively new and the enhanced controller appears in the device list). I've also manually uninstalled the drivers from all USB devices, rebooted the system and let the system discover the USB deives and reload the drivers, but to no avail. Evidently, this problem is not unique to a particular drive type or a specific Windows OS.

    I have the same problem with the Acomdata 320GB "Hi-speed" USB 2.0 Hard Drive. It only works at 12mbit/s plugged into my USB hi-speed 2.0 iBook G4 and won't operate at all when plugged into a belkin hi-speed USB 2.0 powered hub that both operate at 480mbit/s with other hi-speed external hard drives.

    Unfortunately, I haven't been able to test the same drive with different computers.

    yep this happens to me too

  • Anonymous Feb 04, 2009

    Listen!! I own a 250Gb and I had the same problem, I did re-install the USB port drives, but nothing! I have spent ALOT of time now in the net looking for answers and the verdict is this...

    THE DRIVE IS A PIECE OF *@#$ !!!

    I bought it because it is "Pininfarina" design, but the reality is that the quality is very poor, and has no ventilation. (did not research it before buy)

    Most reviews claim this particular product is ****, and that an eminent clink sound will appear, and after that the hd would not be readable.

    It seems that the usb reading card inside is poor quality, and that heat, impacts, or just because, will eventually fail.

    (of course you can open it, in case this happen, and move the actual Disc to a External enclosure, with ventilation (key element in HD failure) and with luck the data is uncorrupted)

    But for now, I need my precious data intact, so I am transferring it while it last to a new HD... reviewed hundreds on the net, and most fail too!!! so finally narrow it down to G-Technology Drives... Yes, they are more expensive, but losing all of my data there is no money on earth that can help..

    These HD are designed with many heat dissipation features, and top quality. These are not sold at usual consumer stores like Staples.. I only found them in MacMall / PcMall... they seem to be professional grade.

    I am very happy I found a way to have my data safe (I also backup to DVDs) but need constant access to it, and these HD are the best my wallet can afford for now.

Hi there :)

I'm no expert, and don't profess to have the answer, but if a device is performing tat USB 2 capacity then suddenly doesn't, and another device performs at USB 2 capacity on the same port, then there has to be an issue with the problem device itself, or possibly an update may have caused a specific, device related incompatibilty issue.

I had the same USB problem on a 2.5 External drive a while back, it also would suddenly shut down during transfer for no apparent reason, I replaced the case and problem solved, it goes like the clappers!!!! Clearly it was something to do with the old enclosure itself.

At the moment, I've suddenly developed the same problem with a 500gb External that up until now has been working absolutely fine. All my other External Drives, a couple 250gb and a couple 350gb, are IDE while this is a SATA, but I don't really think that's either here nor there, as the 2.5 I had issues with is IDE.

This case is under warranty so I've sent it back for testing.

I've spent hours looking for answers, and can't help but wonder if in some cases a lack of power, or loose connection is the issue. The only real difference between my Externals is the actual setups. I wonder if maybe, with plugging and unplugging, they get a bit worn over time, and simply fail to connect correctly.

My old External drives, a couple 8 years old, have solid aluminium cases, with the drives screwed firmly into place as in a desktop. They're solid as a rock, and haven't missed a beat. There's plenty of cord between the devices and adapters, so there's no drag on the connections.

On the other hand, my problem external has no screws, just sort of keepers that are supposed to hold it in place, but don't in fact. There's quite some space between it and the other end of the case/enclosure, certainly it's no snug fit, the drive inside has some movement, so that there's a certain amount of give when you plug into the interface. Also, there's very little length between the adapter and device, I have to be careful where I put it to maintain a good connection Similarly, my problem 2.5 originally had no screws either, just makes me wonder.

No real answers sorry, but some of it may help point someone in the right direction.

It really is quite a frustrating problem just the same :)

Good luck all

I keep getting message saying my pc will run faster with 2.0 hi-speed host. how do i get it

Hi! Welcome to FixYa!

USB versions are USB ver 1.1 and USB 2.0 and USB 2.0 has faster transfer rate.
When you're receiving this kind of message, that means you're using a USB device that is compatible with USB 2.0. This happens when you plugged in a USB 2.0 device to a USB 1.1 port on your computer. It simply notifies you that the USB device can perform faster when you have an available USB 2.0 port. I'm not really sure what kind of computer you have and what version of windows you have but you can actually check if you have USB 2.0 by going to Device Manager, click on Universal Serial Bus Controllers and look for "USB2 Enhanced Host Controller" if you don't have this, that means your computer has no USB 2.0 port. Hope this helps.

None of my usb ports function as "high-speed" 2.0 , and I constantly get the message that my device can perform faster if I connect it to a high speed USB 2.0 port. I bought this computer brand...

you usb ports are to slow for the usb 3.0 device that message keeps coming up saying that the device is better then your usb ports you have on your computer...almost every computer now have 3.0 usb ports that have very fast transfer rates for data back and forth. well i tell you the message you get is not trouble with your usb port it just trying to tell you the transfer rate will be slower with your usb 2.0 port... i hope this helps you.

3.5 HDD external enclosure

One or more of the hints below will probably sort out most USB problems with most USB portable / external hard drives and OTHER devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) 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 especially true if you move a HUB to another port

6. For FLASH DRIVES you should ensure that the device is set for "quick removal" using the drive control panel properties or use the USB "Safely Remove Hardware" option. If you don’t do this there is a very strong chance that any files you transfer may not be there when you plug into another computer.
7. It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.
You should also do this to check the drives connections are not bad inside the enclosure.
8. If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.

9. 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
10. Ensure that you have set removable drives for "quick removal" or that you use the "Safely Remove Hardware" option often shown on the lower toolbar. It is possible that files my not be fully written to external devices before they are removed. This corrupts the file itself and even on occasion the drive.
USB flash drives can fail for no apparent reason.
Sandisk Cruzers are especially bad for this.

USB hard drives should be treated with extreme care.
This is a real hard drive ! And knocks and bumps can quite literally kill them.

Note that if you hear a drive clicking or pinging this could be the worst thing you would hear.
Known as "The Click of Death"
Hope this gives you the information you need


It would be very decent of you to consider the quality of our expert’s answers and judge them accordingly as you pass through FixYa.

Thank you

USB's slow and external drive

For the USB ports, you may want to verify that the drivers for the "enhanced USB" are up to date and for USB 2.0 or 1.1. USB 2.0 ports are generally backwards compatible for 1.1 devices. The "enhanced" does indicate USB 2.0 controller. 30mins to backup 3GB to your external drive is a VERY long time. USB 2.0 transfers data up to 480mbps, but if you get an error message indicating that the device can perform faster on a 2.0 port, you maybe transferring data at 12mbps which is USB 1.1 speed

To speed up the transferring of data, identify which USB contoller in Device Manager is the USB port you're having a problem with, and delete it from Device Manager. Then, plug in your external drive into a USB port its never used before.

As for the naming of hard drives, Hitachi partners with several drive manufacturers including Dell and IBM.

Hello sir, let me give you some tips, you can dismantle it and get the HDD unit, buy a cheap external SATA usb hdd enclosure with USB 2.0 . Well all of them are 2.0 compatible (the unit without the HDD) and put it there. you can always keep the old one for posterity. hope this helps.

It shows this device can perform faster. the pen drive is slow

this is usb issue
your computer usb has a lower version than your pendrive
you cannot use better drivers because this is from mainboard chipset
Also you can put a pci usb card version 2.0 for your pendrive

Usb 1.1 & usb 2.0

USB 1.1 allowed a maximum transfer rate of 12Mbits/second. USB mice and keyboards need only 1.5Mbits/s to function. That performance level is also named 'USB'.
USB 2.0 has a raw data rate at 480Mbps, and it is rated 40 times faster than its predecessor interface, USB 1.1, which tops at 12Mbps. Originally, USB 2.0 was intended to go only as fast as 240Mbps, but then, USB 2.0 Promoter Group increased the speed to 480Mbps in October 1999.
You can use USB device with USB 1.0, USB 1.1 and USB 2.0 as long as your PC or laptop has USB ports, but USB 2.0 device transfer data at 480 Mbps on systems with USB 2.0 support only.

"A HI SPEED USB device plugged into a non HI SPEED USB hub" error message, any idea? every time i plug a usb in to my computer it comes up that this device can perfom faster on a hi-speed usb port

This is not an error it just means that you are plugging in a usb 2.0 device into a usb 1.0 port. The devise will still function normally just not as fast. You could always add a usb 2.0 pci card to your computer.

USB 2.0 vs. Filrewire - video to PC

Hi I have figured it out. Even if the USB 2.0 is faster than the firewire the camcorder itself do not transfer at the optimal speed when connecting with the USB (even id the USB can transfer faster). So the only fast transfer option is the firewire
