Well that is a pickle. If there is no warranty left on it you can allways try to open it up a bit and check with a geiger if the juice is running through it.By Geiger i mean a voltmeter

SOURCE: System freezes when I connect my external hard drive.

Hello

Okay , so there are some steps to figure out what is wrong with your external.

Firstly , if your computer makes a sound when you plug in your external , go to Start-Control Panel-Administrative Tools-Computer Management-Disk Management , and see if your external drive is listed here with your local drives. If it is listed , right click on the drive and change the drive letter to make it appear in "my computer".

If your drive does not make a connection sound when connecting to your computer and also does not show up , please follow the next step.

Remove the hard drive from the casing if possible and install it in your computer case or another external case.If the drive works , the problem is with the casing and you can ignore the drive.

Now , if the problem is with the casing , there are still 3 possibilities.

  1. The USB cable between the drive and the computer may be damaged.
  2. The circuit board which connects your drive to the interface of the external may be blown.
  3. The power supply (if applicable) may have a blown transformer.
The latter is the easiest to diagnose , does your external light up at all when you plug in the power? If not , then this is probably your problem. On the bottom of the adapter is a label which you will be able to use to have a new adapter made at your local electronics shop and this will cost about $30 max. They will also be able to test the adapter with a clamp meter to see if this is really the problem and this should be free.

The second component you want to test is the USB cable. If you have a printer , swop out the cables and see if your printer functions normally. Most externals use the same connector so you should be able to test it in this manner. If the cable works go on to the last step. If the cable is defective , replace it with a new one which you can find for about $10 at most electronics and chain stores.

The last component to test is the circuit board. This is a bit of a grey zone as you probably won't be able to spot the blown component unless it failed really badly. With the casing already opened , locate the external's circuit board and check to see if you have any blackened components or fluids leaking from some components. If all the other components of the external worked perfectly , then this is the faulty part. It is not really economical to replace the circuit as most of the time it is out of production by the time you need to replace it and it still costs a lot even if it is available so if your drive is working perfectly when connected via sata or IDE on your computer , the best is to buy a new casing and place your old drive in the new casing.

A casing costs about $50 and you could get it at most tech shops and big chain stores like Best Buy.

I hope this solves your problem and please reply if you need more help.

Kind Regards
Andrea

SOURCE: Everything worked fine until yesterday

An external storage-device has four major components:

* the USB cable

* the power-adapter

* the disk-drive inside the enclosure

* the USB-to-disk-drive adapter inside the enclosure.

One of these components has failed.

Try a different USB cable.

Try connecting to a different USB port on your computer.

Try connecting to a USB port on a different computer.

Take a "multi-meter" and measure both the voltage and amperage output from the AC adapter, and compare with the specifications on the label on the adapter.

Open the enclosure, and remove the disk-drive, and then connect it as a "slave" disk-drive in a desktop computer, to see if it works at all.

Purchase a new, compatible, disk-drive, and install it in the enclosure, to "revive" your external storage device.

Get the part-number and serial-number from the label on your disk-drive, and access the manufacturer's web-site, and use "check warranty status", to see if they will replace the device, at minimal cost to you.

There exist commercial "data recovery" services that can try to repair your device, just long-enough to rescue and copy your files.
For example, see: https://services.seagate.com/index.aspx?lng=en-US for a "no data - no charge guarantee".

SOURCE: my buffalo external hard disk

it is a PNP (PlugNplay) device. Try using a different cable to connect to your pc. Should the problem remain, hook it up to a different computer and if it doesn't see the drive, it will be an electronic circuit failure inside the box. The data is still on the hhd but you will have to obtain a new circuit to bring the hhd back online for use.

SOURCE: Hi i have a HD-LBU2

first we will deal with the error CRC because there are many CRC errors im not sure which yours relates to
click start control panel administrive tools computer management then select event viewer depending on what operating sytem you have this may vary
in left panel extend the events there you will see errors in red right panel you will no what exactly what the error was and at what time it occured if its a system file error

click start run type cmd then type chkdsk/f which will scan for and attempt to repair any bad sectors and automatically fix any corrupt files on your hard drive this should schedule to happen when you restart your computer another way of running the chkdsk utility
click start control panel administrive tools,computer management ,disk management right click on your drive select properties click tools you should see click check now click start two boxes automatically fix files and scan for and attempt recovery of bad sectors place then a tick in the box to repair the attempt a repair on the files then select check now,start should schedule this task when restart you any input while the chkdsk utility is in progress it might damage your hard drive


click start control panel administrive tools ,computer management ,device manager look through all of your devices if you see a yellow question mark?or exclamation mark ! or red x
right click to reinstall drivers or
if you can see your usb but its not working
ports(com&lpt)right click update driver
sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,

check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems also make sure the computers Ram and Cmos battery are securely seated
if this fails to fix the problem

you might have to install a usb 2 or 3 card they are cheap and easy to install you can buy these on Ebay very cheap
hope this helps you

External HD isnt recognized by ps3


Hmm, go to Start, Control Panel, Administrative Tools, Disk Management. Then look or scroll down right hand panel to find your disk. If it is there you could RIGHT click on it and assign a new drive letter such as Q or R.
If it's not there your external disk could be faulty, the power supply transformer or power cable could be faulty or it could be the USB cable.
If all looks OK you probably need to contact a disk recovery specialist such as DATA365.

Comment: NTFS is a much more stable file system and is much easier to recover after errors. FAT32 is not commonly used now.

Have a 1 tb buffalo external hd. worked great had it for back up. I unplugged it to move my computer. when I plugged it back in, there was no green light no power to the drive. check voltage and the power...


try to test it on other computer or laptop... if the unit are still exist maybe your problem would be the external drive..there are no switch button on it, because most of the switches are located on the adapter, the only testing you could do is to test it to other unit..If the external drive are ok once after you test from other PC's, then might as well check your USB port by plugging-in to other port...or try to use other power supply on your computer, co'z sometimes the supply can no longer supplied any voltage coming from your external drive once it plug-in..

External Buffalo Hard Disk 500 Gb model no HD-PF500U2/BK-AP not detecting when connnected to a laptop or a desktop PC


Check the usb port function in the computer bios settings and be sure that it is set to yes. Connect properly your external drive. If it has two wire usb connections, use both to obtain the maximum power that will be need by your drive.

Plug in 220 v power line, it burns and smokes. Can data be saved?


Is the power supply internal or external? If external, then just find a similiar or identical unit. If internal, then you could try removing the hard drive and installing it temporarily in a desktop system. Obviously, interfaces must match (SATA, IDE). You could then see if it is accessible, and get any files.
