this is a very cool article - apparently many hard drives have unreported space -sometimes lots of it.



inquirer artice here

I guess this makes some sense - we can all overclock mostly because our cpu's are downgraded from more expensive "flagship" processors. It also seems to make sense that hard drive makers produce the highest capacity disks they can, then classify each disk with different levels of storage space to fill different market niches. to put it another way, it shold be much cheaper for western digital to make every drive it produces have a 200gb disk in it, rather than producing some with 200, some with 100, and some with 80. much easier and cheaper (unless i am mistaken) to to produce a 200gb disk, disable 120gb, and sell it as an 80.



with this in mind, perhaps we can start a thread, here or elewhere, that can list results of various makes of hard drives. I won't be attempting this for a bit until I get a new HDD, since this method requires erasing everything on your drive, but I am sure many of you can play around in the interim and get some results!
 
Thats really cool, and makes a lot of sense, in the idea. Im not sure exactly how it works. I will have to give it a shot later. I dont have any extra HDDs around.

Let me be the first to say

HOLY MOSES!!!:eek:

File->Save As

Oh, damn you Tronik, I have physics homework to do, now I want to go play with the pile of spare HDDs I have in my closet. :(

I'm sure many of us at OCers (including myself) have often wondered how in the hell it's cost effective to produce so many platters of different sizes, guess now we know the truth. Only downside is my 80GB is still under warranty, if I were to do this and it were to explode later, I'd be a sad panda.

If for one reason or another, the article goes down, here's the quote:

Unused space on hard drives recovered

Hidden partitions revealed


By INQUIRER staff: Tuesday 09 March 2004, 14:33

READER WILEY SILER has sent us a method which he said was discovered by Scott Komblue and documented by himself which they claim can recover unused areas of the hard drive in the form of hidden partitions.
We haven't tried this here at the INQUIRER, and would caution readers that messing with your hard drive is done at your own peril and very likely breaches your warranty. Here is what Wiley and Scott did. µ

Required items
Ghost 2003 Build 2003.775 (Be sure not to allow patching of this software) 2 X Hard Drives (OS must be installed on both.) For sake of clarity we will call the drive we are trying to expand (T) in this document (means Target for partition recover). The drive you use every day, I assume you have one that you want to keep as mater with your current OS and data, will be the last dive we install in this process and will be called (X) as it is your original drive.

1. Install the HDD you wish to recover the hidden partitions (hard drive T) on as the master drive in your system with a second drive as a slave (you can use Hard Drive X if you want to). Any drive will do as a slave since we will not be writing data to it. However, Ghost must see a second drive in order to complete the following steps. Also, be sure hard drive T has an OS installed on it You must ensure that the file system type is the same on both drive (NTFS to NTFS or FAT32 to FAT32, etc)

2. Install Ghost 2003 build 2003.775 to hard drive T with standard settings. Reboot if required.

3. Open Ghost and select Ghost Basic. Select Backup from the shown list of options. Select C:\ (this is the drive we want to free partition on on hard drive T) as our source for the backup. Select our second drive as the target. (no data will be written so worry not). Use any name when requested as it will not matter. Press OK, Continue, or Next until you are asked to reboot.

Critical step
4. Once reboot begins, you must shutdown the PC prior to the loading of DOS or any drivers. The best method is to power down the PC manually the moment you see the BIOS load and your HDDs show as detected.

5. Now that you have shutdown prior to allowing Ghost to do its backup, you must remove the HDD we are attempting to expand (hard drive T which we had installed as master) and replace it with a drive that has an OS installed on it. (This is where having hard drive X is useful. You can use your old hard drive to complete the process.) Place hard drive T as a secondary drive in the system. Hard drive X should now be the master and you should be able to boot into the OS on it. The best method for this assuming you need to keep data from and old drive is:

Once you boot into the OS, you will see that the second drive in the system is the one we are attempting to expand (hard drive T). Go to Computer Management -> Disk Management

You should see an 8 meg partition labeled VPSGHBOOT or similar on the slave HDD (hard drive T) along with a large section of unallocated space that did not show before. DO NOT DELETE VPSGHBOOT yet.

6. Select the unallocated space on our drive T and create a new primary or extended partition. Select the file system type you prefer and format with quick format (if available). Once formatting completes, you can delete the VPSGHBOOT partition from the drive.

7. Here is what you should now see on your T drive.

a. Original partition from when the drive still had hidden partitions
b. New partition of space we just recovered.
c. 8 meg unallocated partitions.

8. Do you want to place drive T back in a PC and run it as the primary HDD? Go to Disk Management and set the original partition on T (not the new one we just formatted) to and Active Partition. It should be bootable again if no data corruption has occurred.

Caution
Do not try to delete both partitions on the drive so you can create one large partition. This will not work. You have to leave the two partitions separate in order to use them. Windows disk management will have erroneous data in that it will say drive size = manus stated drive size and then available size will equal ALL the available space with recovered partitions included.

This process can cause a loss of data on the drive that is having its partitions recovered so it is best to make sure the HDD you use is not your current working HDD that has important data. If you do this on your everyday drive and not a new drive with just junk on it, you do so at your own risk. It has worked completely fine with no loss before and it has also lost the data on the drive before. Since the idea is to yield a huge storage drive, it should not matter.

310 extra GB of space - that's just amazing.
 
We should know in a day or two... I have some old small disk I could try with tomorrow or the weekend.

Should'nt that work with any old pos?
 
I'd do it with my drive except for two reasons:
1) I'd have to backup 80GB of stuff with a 32x burner :eek:
2) I don't have Ghost :( :D

I was just about to post this message and someone already had beat me to it.

This article sounds too good to be true. I can't wait to see someone do it and test out the new found space. I can't really do it as I've only got a primary 60GB drive and a couple of various drives with between 1.2GB and 10GB of space. Maybe I'll back up my system on a roommates computer and try this ****zle out when I have more time.
 
Well, I don't know about here, but there's a thread at [H] on this topic, and somebody said they're going to do it with an old 10 gig drive. *hopes it works great* :D

EDIT: Read further, and he got 9 more gigs. New space benches as fast as the old, and he's copying files to the new partition to verify integrity :)

JigPu is the man. Check it out, kids:

Highlights:

Testing it out now on an old WD 10gb drive.

Just got 9GB extra on the 10GB drive. I will now test it out by writing a bunch of data to it and see how those programs/movies run on both.

Ok, just got done benchmarking the "old" space and the "new" space

old - 12308kB/s

new - 11785kB/s

Not much of a difference between the 2.

So far nothing is wrong, no errors.

Going to copy a dvd to the hd and play that via alcohal on the space and see what happens.

CRAP only a few more days until spring break... I'm gonna be hitting PC part shops for old 20GBs.
 
Am I ever angry! Spring break just ended for me, so I don't get to do this for 6 more weeks! :bang head :bang head

BAH!

The Enquirer article has been updated, as well:

"** UPDATE II A representative for large hard drive distributor Bell Micro said: "This is NOT undocumented and we have done this in the past to load an image of the original installation of the software. When the client corrupted the o/s we had a boot floppy thatopened the unseen partition and copied it to the active or seen partition. It is a not a new feature or discovery. We use it ourselves without any qualms""

Well so far it is causing problems for me. I think it is overwriting my existing original partition, cuz my windows install is getting all messed up. It is like the new partition has sectors that are linked to the original partition. I would say that it isn't working on this drive. It is corrupting the data on my original partition. You also have to consider that this could be due to the fact that it is a very old drive, and may not work the same as newer drives.

EDIT: It just crashed my computer, so I would say it doesnt work, at least on older drives. I might try and see if works on a newer drive, maybe a maxtor 120GB.

Also an edit to the first post, you don't lose any of the original data when you use ghost. You dont need to format the original partition, so your original data is still there, but I would back it up before doing any of this.
