Iomega 250GB external hard drive. DHD 250-C


I have had this drive for some time and although it is about 3/4s full with data it has had very little use. It apears to be working as normal, clicks at start up and the blue light flashes, it shows ok in My Computer disc drives. The problem is I now get a message that the drive is not formatted and I'm unable to access any data. I ran a file recovery program on it and recovered most of the data but not all. Have you any idea how I can get the drive to run again without formatting it?

Thanks for now,


Harry Reid.

SDHC cards are not backward compatible with normal SD cards..therefore older devices will not recognise them...your built in card reader is probably not sdhc...try downloading directly from camera or use a sdhc usb card reader

SOURCE: 16GB Flash Drive NTFS Formatting

Assuming Windows XP, try the following:

START / RUN... / <type> devmgmt.msc <enter>
Find your USB flash drive listed under "Disk Drives"
Right-click and select PROPERTIES...
Select POLICIES tab
Select "Optimize Performance" & OK
Now select your flash drive from MY COMPUTER
Right-click & select FORMAT...
Select NTFS and format.

This should take care of your NTFS problem but note the warning about safely removing flash drive.
If it doesn't work, run "compmgmt.msc" / disk manager and check for partition issues.

Hope this helps.

The boot info is bad. If there is info that is needed you will have to use a recovery program like getdataback fat 32 and getdatabackntfs

A few things to check but assumes USB for other interfaces similar steps may be followed

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.

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 (Dont use any other unless you know it has both the same voltage and current rating eg. 12V 500mA anything rated below that would not work properly)

If you checked and fixed anything there and still have issues carry on reading.

Go to your control panel and then administrative tools, select computer management.

Now select Disk Management and expand the window.

Your drive should be listed here (if not then you need to check your computer hardware has not got any issues before proceeding)

If your drive is listed and says healthy then right click on it an select Properties, click tools and then error checking, Check now, tick the two boxes and then start.

This will attempt to fix any errors on the drive. It may also ask you to restart which is fine. Allow it to finish its work or you could corrupt the drive. If all went well you should be able to use it normally again.

If you drive was listed ut did NOT say healthy then right click and select Format. Choose NTFS as the file system and do not tick any boxes you do NOT want quick format. Again start and let it do its thing. when it is done restart your computer and you should be good to go.

Hi i loackd my memory card few mnths ago and nw i forgot the password i tried diffrnt paswrds but its stil locked,,,n it gvs option of formating it but i dont want to loose my images vdos n muzik...kindly...

Memory card in a locked condition, the data can be saved. There are two ways you can do:
1. Use the data recovery software (must be software full version). How: insert memory card, run the data recovery process, select the drive memory card, etc. Save the file to your hard drive recovery. After the data saved, memory card format (quick format), then restore the data into the memory card.

2. Quick format memory card, and do the data recovery process. So that data can be saved, do not do a full format, but do a quick format. Tools such as hard drives, flash drives, memory cards, when done quick format, data can be saved.

Is it possible to use a 250 drive from my laptop? If so where can I get a cable to operate by usb?

Most of the shops will offer several solutions. The correct one for you will depend on the interface of the old drive. The drive was either IDE or SATA. SATA drives use a much smaller data cable than IDE. In either case, you can get a 2.5" drive enclosure for ~$30 or less. Alternatively, there are IDE/SATA/USB dongles. These allow the bare drive to be plugged in on one of the sides and the USB cable goes to the computer for ~$35-40. You have to be very careful to orient the dongle plug correctly to the drive data and power back plane. Incorrectly plugged in devices can be damaged. In the case of a SATA drive, there is the option of a hard drive dock (some can hold either 2.5" or 3.5" drives). for somewhat more. Some of these need external power; some of them can work off USB power.

I hope this helps.

    I have a Seagate FreeAgent Desk External USB Hard drive (500GB). It fell about 9" on to carpeting, (very padded I might add), and now my computer does not recognize it. It was plugged into my computer at...

    Sorry to hear about your delimna, these drives usually are running (turning) all the time, unless you specifically set it to go into hibernation mode after so much time.
    However; believe it or not a 9" drop can damage the internal heads to the drive.
    Image the diameter of a human hair, now cut that down to one hundreths that diameter and that's how far the heads fly/rotate above the surface of the internal hard disc. It's a microscopic distance, ANY un-normal jar, bump, disturbance can and will damage, crash the heads. The buzzing sounds like it's either trying to access and can't or it's crashing (making contact, very bad) then retreating.
    I know its a bit too late, but do have any of this data on any other medium? I personally have a 3 redundant backup system (3 separate hard drives), because of this same problem that happened to me.
    You can try a data recovery specialist, you'll have to send them the drive and they will determine whether they can retrieve any of the data or not. Of course they charge for this service, ask before you send it out, also check for references, time in business, etc.
    If you have personal, financial data on this drive, remember they will have access to this information, so definately check them out thoroughly before you commit. Good Luck.

    do you use windows vista or windows 7 OS?
    They have a feature to use an external pen drive as a virtual system memory.
    Try backing up all your data to your hard drive then full formatting it choosing NTFS system.
    If you use OS which are older than Win XP, you need to format it in FAT32 system instead.

    Hope this helps.

    Two questions for ya:

    A) When you say USB drive, do you mean an external CDROM, DVDROM, or mechanical HARD DRIVE or do you mean a FLASH DRIVE? (see below)

    B) When you say "NOT WORKING" do you mean that when you plug it into ANY USB port, you get an error tone; you don't get any response; you see the drivers being loaded, but no drive appears; you see the drive appear, but no files are listed on the drive; or something else?

    From these two questions, we will be much more able to help.

    External devices that have mechanical moving parts, like CD and DVD drives often require external power sources in order for the drive to function. Even external hard drives can require a separate power source. This is because the small amount of electricity provided by the USB port is not enough to power the motors inside these external devices.

    Another type of external storage medium is called a "Flash Drive". It is like a hard drive in so much as it stores data and appears in your explorer/Finder window like a hard drive. However, there are no moving parts, so it never requires an external power source.
