At some point you probably installed Linux to it.
Using Disk Manager or other disk management software (assuming you do not want or need the Linux partition or anything in it) you right click on each of the other partitions and delete them. Then you right click on the first partition and select Expand and when you are given the choice of the new size, you choose the entire remaining space to use the entire drive. If nothing is saved on the drive, you can also delete all partitions and then partition one new partition for the entire drive and then format it.

You have to be a little bit crazy to keep you from going insane.

probably a partition not assigned

make sure you add the unassigned storage to your 750GB drive(letter)
or split them if you want creating multiple virtual disks that show up in explorer

clarification;

it is an EXTERNAL HDD that is doing this.

not internal HDD

per chance... what is the exact model number of the drive in question; and does the capacity you say it has (ought to have) actually agree with specs. for exact drive model you have?

Your video refers to flash drives (pen drives). Does this apply to external HDDs too?

Always pop back and let us know the outcome - thanks

same principle applies, so in theory it could be done.

showing up as a for example 2TB drive but once you fill it up passed a certain point files will start to go missing since you will be writing/reading to a location at 1.1TB
while the actual size is 1TB.

the worst part is that people will find out waaay to late to RMA or get a refund, etc

but i doubt it will happen if you buy the hardware from a business rather than from some random person for a seemingly too good to be true price.(but than again this applies to any product).

"I already tried formatting the external HDD"

Why would you do that? If anything, you have a partitioning problem, not a formatting problem. Please post the make/model of the HDD. Also, which file format did you use when you reformatted?

FYI, the actual capacity of a 1.5TB HDD is approx 1397GB. Have a look at the drive using Disk Management.

This is a Seagate FreeAgent GoFlex 9ZF2N1-500 1.5TB external HDD that originally had the memory size it should have had when I purchased it new from ?? NewEgg or possibly TigerDirect et. al reputable retailer.

Obviously I reformatted it in an attempt to fix the problem.

The file system is NTFS

I checked the partition

there is none other than the main partition

it is conceivable that the drive has been hacked

if so, whoever did it did a good job 'cause I can't find the missing memory now which is about 726GB of the 1397 that I should have

all that shows is 726 and I know it had much more when I purchased it

i guess it is possible it is just a spoof of the memory size and capacity

the HDD is still a 1.5TB external HDD so I probably do have the original memory on it

it is just displaying 726GB in properties

thanks folks

i guess i've been hacked again....

Look in Disk Manager
Look at the graphics of the drive
Does it show more than one partition? Does it show some unallocated or RAW space?
What are the sizes of each space shown for the physical drive, where they are in relation to each other, and the status of each part shown.
If there is unallocated space then you should be able to expand the drive to use all of the available space. Disk manager can do this if the unallocated space is directly after the proper partition. If the space is before it then you will need other software to do this. Depending on what you tell us, we can get more specific on these possibilities.

On another note, you can run Seatools from Seagate and do a short drive test to see the condition of the drive. If the drive has multiple bad sectors (conventional drive) then these bad sectors have been removed from the working drive, effectively shrinking it. If there are more than just a few bad sectors, I would recommend replacing the drive because it is a bad sign that the drive is dying. Don't wait in this case, replace it immediately and if not possible to do it the same day, make sure that there is a good verified back up of important files and do that today/tonight.

You guys were right

It is a partition issue

I just got into Disk Manager and it is showing a hidden partition with no file system type that takes up the other half of the disk

The disk is OK (no bad sectors) and although not brand new, relatively unused so in new condition

There are two healthy partions

One is NTFS but the other large partition has no file system type

so i've found the missing memory and need to now figure out how to create one large partition

partition 1 is the NTFS of c. 726GB healthy primary partition
partition 2 is 2GB healthy primary partition
partition 3 is 20GB healthy primary partition
partition 4 is 648GB healthy primary partion
then there is 10 MB of free space

just downloaded and installed and ran partition wizard

now the partitions are being displayed as;

1. primary NTFS 726GB
2. logical Linux swap, 2GB
3. logical Ext4 20GB
4. logical Ext4 648GB
5. logical unallocated 10MB

Re: response #13. Windows cannot "see" Linux partitions which explains why only the NTFS patition was detected. Apparently you tried installing Linux?

More than likely I tried to back up some Linux files to this external HDD as well as files from a Windows computer (or OS) so in answer to your inquiry, riider, yes, something like that

Please stop referring to "memory" in relation HDDs - - - they don't have memory.

They have "storage space".

Memory is what your RAM modules have.
