Cluster Size vs Slack Space

Q: Cluster Size vs Slack Space

Hello All!

In the old days, Norton Utilities had a slack space analyzer that would show you what the optimal cluster size to slack space ratio should be based on your current disk usage.

Does anyone know of a current utility that will perform that same function?


Preferred Solution: Cluster Size vs Slack Space

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.)

The more clusters you have the slower the drive....is a few extra gigs worth 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?

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

Having run a diagnostic check on my hard drive, 6.3GB.
I have the following Info. 3.8 GB used. 2.5GB free. Slack portion is 20%. I run Win98, with FAT32.
What should one do about the Slack? Is it worth doing anything about it, and how do I go about doing it?

A:Hard drive slack space

You can scandisk and defrag, but that won't really help. I believe you would have to repartition you hard drive inot smaller partitions to change the cluster size which affects the slack (wasted space). If you have an 8GB or less hard drive, using 100% of you hard drive for one partition is OK. Just do a search at www.google.com for "cluster size" or "slack space" and you will find more specific info. 20% Is a little high. My 7.85 GB partition slack is 11%. I wouldn't worry about it, but you couls split you drive up into a hole but 512MB paritions which might decrease the slack, and give you the most out of you hard drive space, but it isn't worth the hassle.

How do you set the default cluster size before installing XP? I hear that a default cluster size of 512 bytes will be beneficial. Does anyone know what other settings can be made before installing XP?

A:Cluster Size

Yes, you would use a third party program such as Partition Magic to format a drive with a specific cluster size. The Format command in XP can set a cluster size with the /A switch.
512 bytes a cluster is a good cluster size for most situations.

I just formatted my 250 GB HD into 5 partitions,basically around 50 GB each using Partition Magic and adjusted the cluster size to 16K. According to the prog, that comes out to about 2-3 percent wasted space in each drive. I am not really worried about the lost space because it is a large drive. I really just want to be able to access the info on these drives as fast as possible, but I would like to hear some peoples' opinions and experiences on exactly what cluster size would be correct for the quickest access with a minimal of waste. I realize there is a trade-off between speed and usable memory and I am leaning toward the speed side. What would be a good "middle-of-the-road"?

Hello guys, I have been reading up on cluster size and how it impacts performance on an NTFS partion. From what I understand, the default cluster size in windows XP is 4kb. I know that increasing the cluster size will improve performance but it will waste space. My question is what cluster size would be optimal for a strictly gaming PC? I am willing to bet that the data files that a game uses are larger than 4kb. I am thinking of raising the cluster size to 64kb.
Is this reasonable?

I've been experimenting with EASEUS Partition Master Home Edition and a spare 500GB WD 5000AAKS external USB disk as part of my self education. Specifically, I've been experimenting with cluster sizes after reading this in the EASEUS help file:

EaseUS Partition Master Manual - Formatting Partitions with partition manager software, unformat hard drive with format recovery software.

The smaller cluster size is, the bigger file allocation table (FAT) will be. The bigger the FAT is, the slower the operation system works with the disk.

Perhaps I misunderstood, but does this imply that using a larger cluster size will cause the disk to be accessed faster?

To test this, I formatted the WD as NTFS using a 512 byte cluster size and then timed a copy of 3.1GB from my internal HDD to the WD USB drive. I repeated the exercise after formatting a second time using a 64KB cluster size.

These are the results:

512 byte cluster size : time for copy = 5min 50sec
64KB cluster size : time for copy = 6min 41sec

The result seems counter-intuitive given my understanding of the line from the help file. Have I misunderstood? What is the benefit of formatting using different cluster sizes? Why is there options to format using different cluster sizes?


A:Question about format cluster size

Good question. Did you copy one single 3.1GB file or many smaller files totaling 3.1GB? That would be an important difference.

Smaller files on a disk with a large cluster size will obviously use more space and I'm guessing that it would take longer to write them because there'll be much more padding at the end of such files in order to fill them up to multiples of the cluster size.

Example: your cluster size is 512 bytes. You write a roughly 17K file. No problem, as the file will occupy 34 or maybe 35 clusters and fit nearly perfectly.

With a cluster size of 64KB, you end up with the 17KB file occupying one cluster and the remaining 47KB having to be padded with zeroes by NTFS - slowing down the file transfer in the process.

A:lowlevel format cluster size

A low-level format is a factory format in which track and sector information is written to the disc. You aren't low level formatting if there is already an existing filesystem, that is a high level format.

With a partition of that size I would suggest 4kb clusters for NTFS.

I'm in the process of migrating to a new laptop and want to determine if I currently have the optimal cluster sizes on my data partitions. I have separate partitions for music, ISO files, video, etc. (These are Extended/Logical partitions.) Obviously using the 4k default for video files makes no sense and I currently use 32k clusters for that partition - but it would be nice to obtain verification of my current cluster sizes.

Anyway, I'd like to find and use a program to perform an analysis of my HDD that would show the optimal cluster size to slack space ratio for each partition.

Anyone know of such a program? TIA, Rob

When you format the drive, the optimal cluster size should be selected automatically, probably 4KB.

If you are offerred a choice, remember that the largest size is not always the most space efficient, although with 1.5T that is probably not a big deal.

How do I determine the cluster size that is from the Manufacturer of any hard disk drive (HD or SSD or External USB HD) (not the ones I can choose when reformatting but what the company that made the hard drive had hard-coded set when they made the drive -sector size)

-and no, I can't go to the hard drive website because some of them do not post this info.

I would like to reformat my usb external hard drives and my internal m.2 sata card back to the default manufacturer disk cluster size (allocation unit)

for example see pictures below..

A:Determine default Disk cluster size from manufacturer

The sector size is fixed by the drive itself and cannot be changed. It is usually 512 bytes.
The cluster size is some multiple of sector size. The default will be 4096 bytes except for very small drives under 2 GB. This can be changed but you need a good reason to do so. The default is almost always best. Hard drives themselves know nothing of cluster size which is a concept imposed by the file system. Nothing in the screenshots shows cluster size.

Loss of Important Files Due to a Disconnection of an External USB HD During Changing its Partition's Cluster Size On Onetouch 4


I have the Maxtor Onetouch 4 external USB harddisk of 500 GBs. It has two partitions, one is 15 GBs, and the other is the rest of the Harddisk's capacity which is I think 461 GBs. Here, I am speaking about the large partition which is Z.
The partition Z's cluster size is 4 KB, the factory setting. After it has become almost full, with nearly 410 GBs of video files, I have decided to change its cluster size to the maximum 64 KBs , because I belive that having the hardisk stuffed with large files (no less than 500 MBs ) makes it better to have a larger cluster size to ease the access of the files. To change cluster size, I used Paragon Partition Manager version 6, and I made sure it gave No warning regards the loss of the files or them getting corrupted.

During applying the cluster size change by Paragon, which was made under Windows XP Pro , SP3, where it wasnt necessary according to Paragon to restart the system to make the changes (because drive Z contains No operating systems ), I said, During applying the change, something happened to the USB connection between the Computer and the Onetouch 4 harddisk nearly in the middle of the process.

Hello all,

I'm going to attempt to create a System Image for the first time with Windows Backup so when I need to reformat I can have the image handy.

My question is this, I'm using 64kb cluster-size on my install drive. Will using the System Tools disc to restore the System Image correctly restore the partition with the 64kb cluster size on its own?

Should I choose the "format and repartition" option if so, or leave it unchecked? What is the difference?

I've googled around and haven't found any discussion on this. Thank you for any input.

A:Restoring Windows Backup System Image & Cluster Size

My guess is that the image is independent of the clusters and you needn't be concerned with it---just as you don't have to be concerned about file systems when installation an application or saving a Word document. The image is just another file, regardless of the underlying file system.

Wait for another opinion--I've just made an educated guess.

Hi there, I hope this problem is a familiar one and easily solved.

then after scanning for 2+ hours, I can't get it to respond. When I click on the
window to open it up, the pc just does not respond. If I leave it for some minutes, it
may open, otherwise I shut the pc down (holding the power button down for 4
secs). I did a Malwarebytes scan, and went I went back to m pc after a couple of
hours, it is unresponsive and I end up shutting it down.
Typically, I have task manager open, or Rubber Ducky, and I have only a third of
my RAM being used, and the CPU is only ticking over.
At other times, the pc is very slow and unresponsive, but again a lot of RAM is
available and the CPU is only idling.
I have followed guidance in:
http://forums.majorgeeks.com/showthread.php?t=106650 (Basic computer
maintenance everyone should do), e.g. deleted unused software and used autoruns
to remove unwanted startup entries, and then get frustrated when it still performs
in an unhealthy manner. Start up and shut down times are good, however.
I am a single pc home user.
If these sound like familiar symptoms I would be very happy to hear a suggestion,

Many thanks, Grest.

I know there isnt a way to decrease the size of spaces, but is there anyway to increase the size of a space after its been made. I have 2 spaces in a pool with the following drives:

1) Backup (no resiliency)

3 tb

2) Storage (mirror)

3 tb
650 gb
200 gb
The first space "backup" doesn't have enough large drives to be fully effective in mirroring. I only need about 850 gb to 1.5 tb of mirroring (have an extra drive that I can add later once everything is setup). The rest of the space I'd like to use without any parity or mirror, just storage of movies, etc (ideally the remaining 3 tb along with the unused 3 tb drive). I couldn't find any way to add drives to a particular space just to the total storage pool. Any way to make this work so I use the hard drives efficiently?

Also, how do you increase the size of a space after its been created? I first made "backup" with the drives in "storage" space. When adding the unused 3 tb drive, there was no option to increase size of the "backup". I wish there windows just showed me the actual size of the spaces instead of theoritcal.

I dont think thinks its the amount of space I have because my external hard drive has about 20 GB left in it. I tried storing other media like photo's in the the music folder and it worked. I dont know if theres a certain limit to how much music you can have in one folder? Can anybody help me, thanks!!

A:[SOLVED] How to make a folder increase in size for more space saving

Hi and Welcome. . .

No, there is no limitation of storage pertaining to a particular type of file.

Go into Disk Management via Computer Management/ Storage - right-click on My Computer, select Manage. Look at the area for the external HDD. What is the total size of the drive it reports? Does it have any partitions? Is it FAT32 or NTFS format?

Regards. . .

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

A:Limit System Restore Size/Hard Drive Space Low

I just paste this into cmd.

vssadmin Resize ShadowStorage /For=C: /On=C: /Maxsize=18GB

and to view what it is currently set at

vssadmin list shadowstorage /On=C:

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


Btw i have posted a picture of my disk management so you can see what it looks like currently

A:Increasing size of c: partition from free space on hard drive

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.

Be sure to post back if you have further questions and to keep us informed.

When I'm nearing the threshold of adequate free disk space for reasonable defragmentation times, I start to monitor my disk space utilization a bit more closely.

Sometimes I notice some strange changes in how much free disk space I have, meaning fluctuations in amounts as high has 3 to 4 gigabytes. For example, I will see I've got 21.6Gb free then suddenly notice it has dropped to 17.9Gb. I use the Disk Clean utility to flush any excess files out, but that doesn't do much. I check the temp folders manually, just to be sure there aren't large garbage files left behind either. I clear the cache of my two main browers. Still no change. I'll go run Windows Update, expecting that maybe some files were downloaded and are now waiting to be installed, but that doesn't turn up much either. I even reboot to see if that forces some kind of clean-up (which sometimes happens), but that may not free up any disk space.

Later on, I'll check again, and sure enough I'm back up above 20Gb in free space. A mystery, as I've no clue as to what changed. Does anyone have an idea as to what may account for such large amounts of disk space being mysteriously occupied and then released?

Also, I just checked my Windows root folder and see it is taking up 11Gb of space. I seem to recall some time back when I first got my system that it was not much above 8Gb. Why would the operating system file tree end up swelling by nearly 50% and is there anything within it that could be pruned without... Read more

Hi Again
I think that the best way is to test yourself. Download win dir stat and it will give you a complete diagrahm of what is on your hard drive at any time.

I'm running windows vista on a dell xps m1330. I've been trying to reduce the used space on my hard drive and locate what is using up most of it. It appears that the cause is my Itunes Music Folder. The first time i checked the size that the folder was, it said 97 GB. So I looked through it and the size of individual folders did not seem to add up. Then I checked the folder size again and it had changed to 47 GB. Does anybody have any idea what might be causing this?

Hello again,

I've got a question about this, since it seems kind of too much of a difference. I got an SSD disk of 60gb with my windows installation and few software. The disk today shows 3gb free space, (out of total 55.8) but the size of all it's folders inside (including hidden ones is 43). There is a difference of 10 GB somewhere. I've read that windows reserve 5-10% of the disk for something (not sure if it's true), but still it doesn't explain the difference. I've ran disk cleanup to free space, nothing changed. This is becoming annoying since if it keeps up, the disk will be full extremely soon.

A:Solved: Disk free space doesn't match file size.
