BackUp Adaptor question

  1. hard drive

  2. The date here today is September 18, 2008

  3. I have an Acomdata Backup Drive, but I have misplaced the Power Supply ADAPTOR. The Acomdata device I have is model number PDHD320USE-72, and its serial number is C1163528. The power ADAPTOR that came with the device is now mixed up with other adaptors or has been lost completely. One of the adaptors I have fits, but I do not know the polarity or volts and watts capacity. I am afraid to plug it in for fear of burning out the device. On the device, there are black embossed letters that say “DC IN,” but nothing is written thereon about polarity and power. The ADAPTOR I’m hoping is the right one, says: “AC-DC ADAPTOR, DIRECT PLUG-IN TRANSFORMER, MODEL :T415600, INPUT :AC 120V 60Hz, OUTPUT :DC 4 5V 600mA, POLARITY :+----.---- - [a ‘backward “c,” pointing to the left toward the “+” sign is where the dot is]. Then there is a UL trademark symbol, and to the right of that, it says “LISTED E182479 5H06. To the left, and below the UL trademark, it says, 0398 SHING WAI CO, LTD. And below that and to the right, it says, MADE IN CHINA. I can get a transformer to step the current down to 110/120 if necessary (the current in Australia apparently is 240)

A photo of this writing on the back of the power ADAPTOR is attached as a jpg file, if I can get an email address. The little green tree-like symbol on your "Description:" section isn't working for me now.

Please let me have a phone number and an email address if possible so that I can speak with someone. I am now in New Zealand and will be going to Australia on Saturday, September 20th and remaining there indefinitely. My phone number in Australia is +61 2 6672 3885.

Thank you.

Warm regards,
Mukunda Goswami

SOURCE: which transformer to use

To solve the problem I tosted the whole mess of wires and equipment and bought new equipment. $8,024 spent and now all the new converters are labeled. The industry needs to mark all equipment with DC-IN 9V or whatever. This is a real problem if you have kids and grandkids and too many different standards.

SOURCE: external hard drive wrong power supply was plugged in

The power circuits in the external hard drive enclosure may have burnt out or the fuse may have blown. Its unlikely your hard-disk is itself damaged.
You may remove the actual hard-disk from the enclosure and put it in another and access the data.
All the best!

SOURCE: Acer Aspire 5002WLMi Notebook power adaptor is overheating

You will nned to make a test with a multimeter to see if your adapter provide the rating charge your laptop need.
Then see if your heatsink it is not so dirty, if not, try to apply termal compound to your heatsink and check if your blower spin good, you will need to remove your Mobo, this is a mayor fix, so try if you have expertise.

If you still have problems we can replace your heatsink and termal compound for $60 usd

SOURCE: ac adaptor to evesham laptop light is flashing

You must make sure the polarity is right on the ac adapters, if you are off on anything ei; voltage or polarity you can easily fry the motherboard. If you have your old adapter, look on the specs and match EXACTLY when purchasing generic-just my 2 cents. If it doesn't match you still may have a chance(slim)-good luck!

Will an Acomdata external hard drive (Model # HD25OUHES5-72, Serial # C1005093) work with Windows 7

Windows 7 is a pain with large external hard drives you might get messages saying the hard drive needs to be checked or formatted do you want to check the disk now or do you want to format it now.

When there is nothing wrong with it at all.

External hard drives can be used on most computers and operating systems with minimal or no requirements other than leads and drivers.

Try it and good luck.

Hope this helps

Acomdata external hard drive not opening MBP

Acomdata Drive Not Recognized: I ran into the same issue. Actually the issue was with using an incorrect power adapter. It should be with power ratings of: Input 50-60 Hz 1.2A & Output 5V - 2A, 12V - 1.2A

I can't seem to open my external acomdata hard drives. My computer doesn't recognize them and when they do open they will close in a few minutes.

Either the power-supply for the external drive is dying,
or the disk-drive inside the external case is dying.

Quick, make a "backup" of all the files on your ACOMDATA, before it totally "dies".

If it still is under warranty, exercise the warranty, and replace it.

Backup question

Once you save the data on the external drive it will stay there until you delete it from the external drive. I personally run (2) 1 terabyte external drives and I save My data on 2 separate drives. I have had them fail in the past. This is the only way to ensure you will always have a good copy no matter what. At the time I had only 1 500gb external hard drive and it was nearly full. I bumped it when it was running and lost every thing I had! With the low cost of external drives I recommend buying two of what ever capacity you require and making redundant backups, this will assure you your data will be safe. If you have any other questions feel fre to contact me at Send me your number and I will call you for free. I do this for a hobby just to help people. Please take the time to rate this fixya for me and I will assist you with any problem you have. Thank You,

Firewire problem I think - I have a Sony Vaio laptop, the firewire port is 4 pin, it is connected to a LaCie CD Burner via 6 pin and the burner is daisy chained to a AcomData external hard drive via 6 pin....

If the hub has an external power supply it migh do the trick. That way you can have a backup port if needed.

Make sure the hard drive isn't connected to the hub. Sometime windows doesn't see it when its connected to a hub.

Redemption Backup crashes

I have the same problem and have asked Acomdata several times how to fix it.  They say they'll get back within 3 days, but they never reply, Acomdata doesn't support their products.  Buy something else.
