Available Drive Space < Drive Size - Sum of Existing Files

Q: Available Drive Space < Drive Size - Sum of Existing Files

I'm not sure if this should be posted in the Windows software forum or if the Hardware forum is appropriate so I'm starting here.

I recently purchased an external USB drive (WD My Book 160GB) as an external backup drive for my desktop. My question/issue is that Windows is reporting the available drive space at a value that is far less then the total size of the drive minus the sum of the drive space of the existing files on the drive.

For example, the My Book drive is 160GB. Using Windows Explorer I determined the amount of space the existing files & folders on the drive are using by right-clicking each file or folder in the root of teh drive and selecting 'Properties' and using the 'Size' and 'Size On Desk' values in the 'Properties' dialog. The sum of the 'Size On Disk' value of each folder in the root of the drive combined with the same for each file in the root equals 120GB (rounded to the nearest GB). According to the 'Properties' dialog for the drive (right-click the drive in Windows Explorer and select 'Properties') there is 15GB of available drive space.

120GB + 15GB = 135GB

What happened to 25GB of space on the drive?

I used Windows Disk Management to verify the drive space. According to Disk Managment the USB drive has a capacity of 149GB. This raises another question, what happened to 10GB of drive space? The thing is supposse to be 160GB and yet the capacity accoridng to Windows is 10GB less. I know that some drive space on every drive is used/reserved by the OS and or other system processes but 10GB? Doesn't that sound high?

Even if we use the Windows Management reported capacity of 149GB of total drive space, there is still a 15GB difference between the availablee drive space plus used drive sapce acording to Windows Explorer and the capacity reported by Disk Management.

Anyone know
1) Why the available drive space started out with 10GB less then the total size of the drive
2) Why the Drives Capacity minus the sum of used space on the drive does not equal the available drive space according to Windows Explorer.

Preferred Solution: Available Drive Space < Drive Size - Sum of Existing Files

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

A: Available Drive Space < Drive Size - Sum of Existing Files

The short answer to there's two different measurement formats used. Decimal (GB) and binary (GiB) formats. Binary is used by Windows and decimal is used by the manufacturers. Both the manufacturer and Windows are giving you the "correct" number at about 149.
That explains some of it but honestly unless the external drive has a hidden partition, which is possible as some of them put on software to backup and also do a backup image file as well.

I have a HP Pavillion dm4 laptop with 2 GB RAM running Windows 7 and I am facing this problem. I have partioned the hard disk drive into C and D , C for Operating system files and D for Documents.

I tried to check how much space is there in C and it indicates only 2.9 GB is free of 50 GB C. but when I enter C drive and select all the folders and files, and click on properties, it shows total size of files on disk is 43 GB. so then I should be having free space of ~ 7 GB.

Now where the extra space go ? I dont understand this. And I enabled to view all the hidden files and folders, . Can someone help me out ?

A:C Drive shows less space than total size of all files

When windows downloads updates it creates restore points which is stored on the c drive. You might have made some your self at one time or another, these wouldn't show up because they are hidden. To clear these out you need to go in to control and then system. Click advanced settings and then click the system protection tab. You can clear out the restore points from there but keep in mind that you won't have any restore points so if anything goes wrong you won't have a restore point to go back to.

Hi. I'm wondering if I add free space to one of my hard disk drivers would it delete all the data in it formatting it?

I have a free space of 50 gbs unformatted. I want to add this space to my F: drive using disk management through right click menu "extend partition" (right clicking to F: drive) though I'm not sure if all the stuff in F: drive would be deleted if I do that.

I'm using Win 7 Ulti 32bit. Btw, you have great forum. I've been using the forum for many of the tutorials on 7 stuff. Checked tutorials section before registering and posting this. I couldn't find a related question or tutorial in the forum.

Thanks in advance.

I have an Optiplex 780 Desktop and would like to install a second hard drive between my existing HD (connected to SATA0 on the motherboard) and my CD-DVD (connected to SATA1).
I would like to use the space between the normal HD (at bottom of the drive area when the 780 Desktop is lying on its side horizontally and not standing up vertically) and the CD-DVD (at top of the drive area).  The space in between is designed for a floppy disk drive, which has never been in the PC.  It has always been empty space.
Last week, I tried, but found that the empty floppy-drive space was a cm too short for a new, second drive.  I could not slide the new drive all the way in unless I left off the small black plastic cover that normally covers the unused floppy-drive "front" on the case.  (I had added side-screws to the new drive and was not using one of those blue plastic caddies.  This floppy-drive space seems only to work with the side screws; a blue plastic caddy seems to be good only for the original HD space at bottom.)
But the Dell manual for the Opti 780 Desktop definitely shows the possibility of a second hard drive in that space. 
What's the trick?  Are some 3.5" drives longer than others?

On a Windows 7 machine, have the OneDrive and Dropbox folders on a separate 150GB hard drive, E:.  When I open Computer, it says my E drive only has 500MB available, when I highlight everything on the E drive (i have hidden files and system files visible)
and do a properties it only adds up to 65GB of data. 
I ran a chkdsk on E and it didn't find any issues.  How can I reclaim my 85GB (150-65) of "lost" space back?  Or how can I figure out what Windows thinks is using it.

Why is it that the computer does not show the full amount of space available on a hard drive that is empty?

For example, I have an 80gb drive and it said that I have 76.69gb available even when there was nothing on it! My 60gb drive says 57.27 is available. And when I partition them the partition sizes add up to those numbers. Where does the extra space go and why so much?

Also....when I partitioned it asked me what size I wanted my clusters...64k, 32k, 16k, 8k, 4k, etc. Now I understand that the smaller cluster size means less wasted space when files are saved but what is an optimum size or does it matter?

Hello everyone,

I installed Ubuntu 10.04 on my computer about 3 months ago, so i split my 500gb hard drive into 2 big partitions. But now i didn't feel the need for Ubuntu anymore, and decided to delete the partition. Now i have 173GB of free space on my hard drive that i want to put onto my C: drive where my windows partition is.

The problem is the c: drive will not give me the option to extend the partition, and i have no idea how to get that free space on to my windows C: partition.

If you guys could help, that would be great

Hello helldemon80, welcome to Seven Forums!

Have a look at Options One & Two in this tutorial at the link below to get an understanding of how to go about what you want to do, it will help you recover any space you need to recover.

As the C: is "System, Active" you would be able to recover into C: the "I: System" partition to the left of C: also.

I'm trying to summarize here. I Googled this topic and found bits and pieces about how to do it, but not all together at once.

Original Q & A:

Q: "I have system restore set with an unbound upper limit, is this going to cause any problems later?"

A: "It depends on whether you need the hard drive space that you set for it as it fills up. As the space you set fills up, older restore points will automatically be deleted to make room for the new ones, so you shouldn't have a problem at all."

Now, as for viewing or changing the allocated HD space for System Restore Points, the only thing I can find is doing it via command prompt.

I won't go into what the command prompt is or anything because anybody who is worried about the size of System Restore Points probably knows their way around the command prompt and the Registry as well.

Anyway, to sum it up:

At the command prompt (Admin), to see the currently allocated space type: vssadmin list ShadowStorage

As in:
C:\Windows\System32>vssadmin list ShadowStorage

You will get an output like this:
Used Shadow Copy Storage space: 1.291GB
Allocated Shadow Copy Storage space: 1.563GB
Maximum Shadow Copy Storage space: 11.25GB

Sizes you see listed as well as sizes you can enter are in KB, MB, GB, TB, and up.

As you can see, 1.29GB is currently in use on my system.

To change the amount of used HD space: (increase or decrease)

vssadmin Resize /For=C: /On=C: /MaxSize=4GB

Change the drive letters to ... Read more

Sorry if this is the wrong forum.

Yesterday my external hard drive was working fine. Today I open it and there's a new folder called Pfiles...I am not running linux...and a tmp file. I delete the tmp file and try to delete Pfiles but it won't delete. Weird. So I open one of the folders and see that it's now empty, as are almost all of my other folders and subfolders. My daughter's folder however has her movies on the main subfolder, but subfolders in this folder are also empty.

The hard drive is showing half full...exactly what it should assuming I could access all the files. So what can I do? I've enclosed a screenshot of the Disk Management screen for this drive. Thoughts?

Thanks in advance.

A:Help with external hard drive. Files "missing" but still taking up space on the drive

Hi djfl,

External Hard-drives come in different types, some of them are, External storage devices and Automatic back-up devices.

If it is an automatic back-up device then data might be backed-up on the External Hard?drive without user intervention.

If it is an External storage device the files might be hidden. This could be the reason why the external Harddrive is showing half full. We can check if the files are hidden, please use the following link for detailed instructions to unhide folders: Hidden Files and Folders Option - Add or Remove

Please revert back for clarification.

My primary HDD was failing so I backed it up and replaced it with a larger 1TB drive.  After reinstalling everything the new drive is displaying the same size as my old drive and the extra space available is unallocated.  I can allocate it as
a separate drive but I find that annoying and would prefer to just have my primary C: drive show up with all of the available space.  I formatted the extra space and made it available separately as drive G hoping that I could EXPAND drive C but that option
is not highlighted as selectable on drive C for some reason.  Should I just live with this extra space or is there a way to easily combine C and the new G space?

I have 4 - 250gb SATA drives on my WIN7 machine. One has WIN7, One has Vista (I dual boot) and the other two are used for storage. I want to replace one of the storage drives with a larger capacity drive 1TB.

In looking inside the cabinet I cant tell which drive has what on it.

Can I just unplug the cable on one drive at a time and identify it that way? Or would it create a problem, such as, Windows renaming the 3 remaining drives?

What's the best way to do this?

A:losing drive space and not even downloading any files

Hello miketseng, Welcome to TSF!

Firstly, lets look at cleaning the 'garbage' from your computer.

Windows? does have a couple of built-in 'garbage cleaners'.

1: Right click > Internet Explorer Desktop Icon > Properties > Delete cookies > OK > Delete Files > Tick the box > Delete all offline content > OK ...now click the Content Tab > Clear SSL State > OK .

2: How to use the Windows? XP Disk CleanUp tool. ( Click the coloured link. )

These two utilities will help keep the HDD 'clean'...use them both regularly, as well as using The Disk Defragmenter once a week.
Both of them will only delete the unnecessary 'garbage', whereas other system cleaners can remove vital files.
I have got into the habit of using Method One every night as part of the shutdown process, and Method Two once a week.

If you do not regain a substancial amount of space; then, further investigation will be required.
Try both Methods, and post back with the outcome.

Kind Regards,

This just happened right now actually. My Drive C: suddenly ran out of space as I was using it so I checked out what was wrong. After running Disk Cleanup I saw Temporary Files was eating a whopping 8 GB of space! So as would any other person I performed the deletion using Disk Cleanup.

You'd think it would be all fine after that but the problem is that 8 GB of space did not return. My Drive C was still the same space as it was before the deletion. I performed the Disc Cleanup again and saw everything was okay that it said it cleared everything.

So the question is why didn't my space return? I'm thinking it's either my space did return but my HDD isn't updating the values, or the space didn't return meaning all that space is still there somewhere.

I've already preformed the following:
- Emptying Recycle Bin
- Using CCleaner
- Performing chkdsk
- Limited the System Restore

I recently came across the following remark by a respected computer guru and would like to have the comments of those in this forum. I personally delete my Temporary Internet files every time I close my browser. But now I am wondering if that is the best "habit" since I have ample hard drice space.

"Considering that each web site could have hundreds -- or even thousands -- of individual Temporary Internet Files saved to your computer, the downside is that you will lose hard drive space. Having said that: if you constantly delete your Temporary Internet Files strictly 'out of habit', you'll not only save space, but you'll also severely fragment your hard drive. This is especially true if you have more than ample space to store your Temporary Internet Files (and deleting the files is therefore not necessary)."

I went to SSDs on all of my computers some time back, but I still use WD RE4s and 2.5 inch WD Black HDDs for a variety of backup tasks and for storage in which the data will not be accessed for a period longer than is ideal to use a non-powered SSD for. On my Macs I am using El Capitan with OS X Journeled, GUID map, and FileVault 2 encryption. On my SP3 and desktop I am using NTFS with Win 10 64-bit Pro with BitLocker enabled on both machines. The OS and third party programs are currently up to date.

I've generally used ExFAT and the GPT partition map because it allows me to use it on all of my computers, and I have always used the default cluster size. However, I do not think the default size was the best decision for me because the size on disk is over TWICE the actual size.

If I am correct, the default Win 10 cluster size is 4k, and that going BELOW that is useful for the drives I have many smaller files on. Is this correct? Additionally, the smaller cluster size I go, the slower the drive will write, correct? Also, if so, how low do you advise going? I am still torn between reformatting outright or trying one of the programs that allows changes to a currently in-use drive. Any advice? Thanks!

A:Hard drive cluster size issues? Size on HDD over twice the actual size

For the a sector size of 4k to double your disk utilization you'd have to have a really tiny average file size. From your numbers shown the average size if I calculate it correct is 132kb (unless you have 1 massive file and 17,711 tiny ones) so a 4k size will make no difference.

You could check with TreeSize Free - it will tell you if you right click on the status bar and select it to be displayed.

EDIT - having checked the default for ExFat is 128k for drives over 32GB (https://support.microsoft.com/en-us/kb/140365) and when I tried to format an external USB drive that is what it picked. According to macbook - Reformat exFat with specific Device Block Size and Cluster Size - Ask Different OSX picks 128k also.

So if you had 128k as your cluster size minimum disk utilization would be 17,772 files * 128k = 2.17GB. So if all your files were just over this (say 132k which looks like your current average size) you would be using 4.44GB add a couple of big files and it could easily be 6GB.

I would check your average file sizes and also your current cluster size (you can use chkdsk as described in the AskDifferent link above).

The default is 4k for NTFS and I have always formatted ExFat as 4k also. Depending on your current setting reformatting 4k looks like a good idea.

As for how - copying the data elsewhere, formatting and then copying it back has to be the easiest, safest and most likely fastest way. You'll also get the disk defragmented automatical... Read more

i was copying some files into my external HDD, into a folder called, "ABCDE". a few days later, when i plugged in the HDD into my laptop again, that whole folder was gone, along with alot of the other files. some of the files can still be seen. however, i was sure i did not somewhat accidentally delete the files, as the stuff visiblr to me on the HDD is only 28 GB or so, and when i clicked on "properties" for the HDD, it states that 240 GB was used. I tried recreating the folder "ABCDE" again so as to re-copy my files in, but Windows said a folder with "ABCDE" already existed, and asked if I wanted to merge the two folders together, although Windows search results on the HDD came out with no results. clicking on "Merge" did nothing at all, there was still no "ABCDE" folder. I have tried clicking on the "view hidden folders" option, and $RECYCLE.BIN and $AVG. turned up, (i did a stupid thing to delete $AVG. in a rash moment) and the next time i plugged my HDD into my laptop, an additional RECYCLER folder popped up. i switched off the hidden folders option and $RECYCLE.BIN was still there, and still is now. thinking it may have been a virus, I scanned using McAfee, and McAfee was actually scanning files that I had in my HDD, but cannot be seen by me, and cannot be searched by Windows. How do I solve this problem?

Okay so i was doing your usual conversion of a FAT32 drive to NTFS using Paragon partition manager.

The problem is around 80% of my files are now no longer showing on the drive, but the space for them is still allocated. That lead me to the conclusion theyre still on the drive.

I decided to finish the conversion on Paragon which kept bringing up an error. After running a CHKDSK /F fix acronis carried on the operation as per normal and reached 100%. STILL MY FILES WERE MISSING.

I then decided to run numerous recovery programs to see if i could find the files. However they all picked up zilch...

My final idea was to run the seriously time consuming CHKDSK /R as a last ditch attempt. All was going well until it came up with an "unspecified error" at the end of stage 5. Now im all out of ideas...

I am going to try defraging and running CHKDSK /R again to see if the error is a reccuring one... If it is then im stumped. Its just really annoying because my files are still on there! The space is allocated but theyre just not showing up!!!! ARGH!

Here's the story...

A while ago the hard drive in my lap top (HP, windows xp) started aking weird clicking noises and then it would crash. After a couple of times I ran the trouble shooter and it said it had a bad connection so I took out the HD, dusted the connections, put it back in and restarted. Seems to have worked, clicking gone, no more crashing. However, after I restarted windows ran something called "diskcheck" or something like that and deleted or reformatted some corrupted files, it also said it was backing up the system at some point. My computer now works fine. However, I have an 80gb (74.? to be sort of precise) hard drive and had about 38gb of free space left on it. now it says I have only slightly over 4gb of free space. I've tried defragging and all that, but it doesn't even have enough space to defrag properly.

After checking out some forums and asking around a bit, the most likely problem I can figure out is that windows has backed up and copied everything on my hard drive back on the it self (the math seems to work out- I have about twice as much space used as I did previously, minus the master boot).

My question is: How do I access and delete the unwanted doubled data?

I've been working at it for hours and am at the end of my tether on this.

Thanks very very very much to anyone who can shed a bit of light on the situation.

A:missing hard drive space. Hidden back up files? Help!!!

You may be losing lots of space to System Restore. You can turn it off and erase it all, but I'm not sure if you can pick points to save. I never use System Restore on my own machine, and at the moment, am not using Windows, so can't check for you, sorry.

I have 6TB in 1TB Hard drives. On my D an E drives is a Documents and Settings folder that has a shortcut icon. Whenever I try to delete them, the corresponding files are deleted on drive C! It appears that the files actually exist on D and E drives. So these folders are not actually shortcuts. I think these are left-overs from now dissociated backups. This means they do not appear in Backup and Restore. In adding drives, there was a lot of shifting of associated drive letters along with a lot of manual file moving. The Backup schedule is turned off and even where the Documents and Setting folders appear there are no longer any additional backup folders, just the Documents and Settings folder. How can I recover this space? I may need step by step instructions!

Thanks for any HELP!

A:Abandoned Backups? Can't reclaim drive space and keep original files

Right click on the icon.
If it shows "open folder location" then it's a shortcut to a folder
Click properties >shortcut tab under "target" will show the location of the folder.

I moved about 10GB of files (using Photoshop Elements) from my laptop's hard disk to an external hard drive. I double checked and the files were moved correctly - they don't show up on the laptop and show up on the external hard drive. However, the laptop's C drive does not show an increase in space. I restarted the laptop but it still shows the same free space as prior to the move.

Any idea why? This is with a Lenovo T440s with Win7.

We're totally perplexed. The computer, Windows XP operating system, has a winchat.exe error problem. The other day, after it was turned on, an error appeared: "To help protect your computer, windows has closed this program. Name: windows for workgroups chat (NT)." It popped up over and over again no matter how many times we closed it. Then the computer told us that the C drive had a critically low amount of space. We searched around and found the following file repeated thousands of times until it literally filled the C drive: winchat.exe.20090327-052356-00.hdmp. The numbers varied a little. Almost all had exactly 2860 KB. They were all located in C:\windows\pcheatlh\ERRORREP\UserDumps. We deleted them all and emptied the rec bin. But then they all repopulated and filled up the C drive again. My colleague went to the server and disabled error reporting under My Computer, Advanced, error reporting. We deleted the files again. The Workgroups chat error disappeared. For awhile, everything seemed okay, but when we turned the computer on the next day, the same "windows workgroup chat (NT)" error appeared and couldn't be gotten rid of. We deleted the files again, and they came back. The workgroups chat error is no longer showing up, but the error files keep generating. Now it's doing it on another computer on our server. It literally pops up these error messages over and over. Please help us!!

A:Solved: winchat.exe error junk files are filling up the space on the C drive!

Uninstall winchat.exe. Go to Start > Control Panel > Add or Remove Programs and click on Add/Remove Windows Components. Find winchat, and uncheck it, then click OK.


If it doesn't show up in Windows Components, you can try this at your own risk-I offer no guarantees.

Go to Run box and type :
runDll32 advpack.dll, LaunchINFSection %windir%\INF\winchat.inf,BLC.Remove

My pc has been very sluggish for quite some time now; it gets slower and slower the longer it is left running and my suspicion of a virus/malware infection was confirmed when the Panda ActiveScan picked up a bunch of threats.
Right now, there are 7 svchost.exe files running in my task manager: 4 are SYSTEM, 2 are NETWORK SERVICE, and 1 is LOCAL SERVICE. I don't know if that is a big deal or not but it seems odd that there are always at least 5 - 6 svchost.exe files running.
Also, my disk space has been decreasing recently; I have not downloaded/installed anything recently (besides the 5 step requirements for this post). I had 2.07 gigs free in my C drive today morning; there are 1.92gigs left now in the same drive. I currently have Kaspersky Anti-virus 7.0 and Sunbelt CounterSpy installed on my pc.

Hi All,

I found this thread "05-Jul-2007 02:36 AM - Loads of *.TMP files created automatically in c:\windows\system32 " on http://forums.techguy.org/malware-r...38-loads-tmp-files-created-automatically.html while searching for a problem I was having.

it was posted by DidoWide on the HJT forum, so I was unable to post a reply, nor could I send DidoWide an email to ask how he solved in in the end, but I have the exact same problem!

This is what happens:

Two times now, at a seemingly random times (both times round about 11:00AM), all of a sudden, loads (and I mean tens of thousands) of TMP files, looking like 0fb149fbcb12b2799cfd1c55fc08b4e9.TMP are pumped into my system32 folder. In a matter of 15 or 20 minutes, this may generated as much as 5GB of used diskspace. Some are 0K, some are 91K, but other than those tow, sizes seem to be constant.

As this happened at work, I didn't have time to launch something like process explorer or similar to check which process has handles in that directory. I just gradually cleaned up the files (which took a long time!), and the problem went.

First time 24/9
Second time 5/10

Whatever process was doing this, has stopped generating the files after a while but this could be due to the fact that my Harddrive was having 0MB free then.

Both times, I was working in my Office Citrix Presentation Server 4.5 environment, with published apps (about 9 or ten open), connected through PNA/ Not sure if that's relevant, but I thoug... Read more

Lately I have been using a program called Xfire to record some gaming clips. The uncompressed files are pretty large (60gb/40 mins of gameplay). After I delete a file, there seems to be less space on my hard drive. For instance, yesterday I recorded and then deleted a clip, and I noticed I had 1gb less space on hard drive afterwards. I emptied the recycle bin, used the disk cleanup utility and did a defrag, but the 1gb was still missing.

Can anyone help me find the root of this problem?

Much appreciated,

Hello, I'm going to be replacing my primary HDD (1tb) with a SSD and will place the HDD in a drive caddy, replacing the existing DVD drive. 3rd party vendors list both 12mm and 9.5mm drive caddys for this - I imagine a newer laptop would have the smaller form factor, unfortunately this spec info is not available from the manual or Lenovo tech support - does anyone happen to know? Might be best if I yank the drive and measure it or take it with me to buy a caddy in person, rather than order online. Thanks for reading,Paul

Hey guys I was wondering if it's possible to put in a 3 or 4 tb hard drive into my laptop. The current max it says in the manual is 1 TB, but it also says that for other laptops but is possible to upgrade. I have an m.2 nvme 256 gb and a crucial 750 GB SSD in it right now. They are GPT formatted and it does have uefi, so I don't think it'll be an issue. But I've read about HP limiting sizes in the BIOS.  And also I cannot find this type of connector cable anywhere or what it's called. I do have pictures of it though. Thank you http://s36.photobucket.com/user/ahsfisher/library/?view=recent

A:Hard drive size limit in BIOS? What connector is the drive

@djmagnum You're going to have a problem using any drive larger than 2TB because they have to be formatted GPT -- and unless your current drive is also formatted GPT, you will not be able to "clone" it onto the new drive due to formatting differences. Here's a thread that shows you how to check to see what formatting was used for your drive:  http://www.multibooters.com/guides/determine-if-hard-drive-is-mbr-or-gpt.htmlGood Luck

Hi everyone,
I installed Ubuntu on my computer a few months ago and created another partition for it on my 1TB hard drive.

I didn't really care for Ubuntu so I decided to delete the partition it was on.
That might have been a mistake.

Well, now there's 87.68GB of free space on my hard disk that I can't use and I don't know how to add it back to my c: partition.

There was another post about this a couple years ago, but I don't understand the instructions and am not actually sure if it worked. Can someone explain how to do this, please?

I'm not completely computer illiterate, but I'm not familiar with partitioning disks. It was just the one time with Ubuntu.

A:Hard drive partition: adding free space back to c: drive

The unallocated area is actually an empty extended partition. You need to delete that first.

Ok, this is a weird question, I know, but I don't know exactly how to Google this to find the answer.

I have a 1.5 tb external drive (which shows up as something like 1.3 tb in Windows). I use it for storage, but now I have it set up to automatically back up my internal drive. Now it shows up as 1.04 tb in "My Computer." I looked in "Disk Management" and it seems to have three partitions, two of which have no drive letters assigned. So, I just have one quick question, is that normal?

The reason I ask is because today I was messing around with dual-booting Ubuntu. I just wanted to make sure I didn't mess something up.

To anyone who answers, thanks for putting up with a stupid question, lol.

A bit of background...
-I have a Lenovo x61
-I have backup DVDs for Windows Vista to restore the computer to the factory state

So I wanted to play around with Windows 7 and I also realized that I didn't need the hidden service partition at the beginning of the drive if I had the backup DVDs. So, I figured if I were installing a new OS anyway, it would be a good time to kill that partition.

I proceeded to kill the partition successfully in Vista using diskpart and I was left with approximately 5.5GB of unallocated space at the beginning of the drive. I had read several places that if you did a clean install of Vista with unallocated space, it would overwrite that space and give you access to the whole drive in a single partition (so much for stuff you read randomly on the net ). So, I thought that probably was the same way Windows 7 worked as well. I then popped in my Windows 7 DVD and selected clean install. Everything about the install worked great...except I still have the 5.5GB of unallocated space at the beginning of the drive.

Does anyone know how to get rid of this space and merge it back into the main partition? If the solution involves reinstalling Windows 7, that's fine (since I just did it yesterday and have hardly customized anything).

Thanks in advance for the help!

Also, here's a picture of the current state in disk management. One other question, what's the other part of the HD? RAM or something to do with Intel Turbo Memory?

Hey guys,
I have an issue that suddenly appeared. My 500GB SSD has apparently not enough space on it anymore. Sadly, that cant be true since only half of it is used and I have absolutely no idea how to fix that. Not even deleting stuff changes anything about it.
So I tried to look it up in Disk Management and in there it says that the drive is fine and good, but it also shows another 500GB SSD which is not initialized. So I counted all my drives and I know for a fact that this drive should not exist. So I assume the two issues are connected.

This is how the Disk Management looks like: https://gyazo.com/d8269c646ce3d7c342b98ae01745ce29

Any idea?
