How to recover unallocated space?

I'm using windows 7 home basic 32 bit.
For some reasons I need to reinstall it a few weeks ago.
At the time of installation I deleted 'system reserved' & 'local disk C' partitions & install new version of windows.
After installation there is 3mb unallocated space.
How I recover that?

I used many partion managers. but this 3mb unallocated space not recovered yet.
If anyone knows solution to this problem, please help me?

Suppose you can't recover the 3 mb of space.

Will you be able to cope with that?

Or will you be in a constant state of anxiety and frustration?

3MB is a nit. Just forget it.

There are programs with which you could recover it, but you may make more damage than it's worth.

These small unallocated spaces at the beginning and/or end of hard drives are created under various circumstances for "housekeeping" purposes by the OS.
You should leave them alone unless you know what you are doing.

Here is a typical explanation from Acronis:

Re: Small unallocated space automatically created
Hello all, Thank you for choosing Acronis Disk Director.
Please accept our apologies for the delay with the response.

churin, the exact size of the space created is not clear from message.

However, let us explain one thing, it is related to 7,8 MB's of unallocated space on each drive.

There are two situations in which partitioning software (i.e. Acronis Disk Director) can detect an area of unallocated space of up to 7.8 MB in size that was not created there manually:

1. Up to 7.8 MB (minimum of 1MB) of unallocated space resides in the end of the hard disk. This area is reserved by Windows (NT family) operating systems for the purpose of creation of Dynamic Disk structures. This unallocated space area is not shown by Windows Disk Management; however Acronis Disk Director is able to merge it with an adjacent partition. Therefore, after doing that there can be problems with creating Dynamic Disk structures.

2. Exactly 7.8 MB of unallocated space reside in the beginning of the hard disk. Normally this means that there are no Primary partitions on the hard drive and the hard drive contains an Extended partition only. In such cases Windows reserves the minimal amount needed for creating a partition (7.8 MB) in order to be able to handle the only Extended partition properly. It is not recommended to remove this area. Even though technically it is possible to merge it with the Extended partition, this may result in the data on it becoming inaccessible.

Detailed information about Acronis Disk Director product can be found in User's Guide.

Thank you.

You can do it by the software called EaseUS Partition Master. It is a automatic recovery mode which requires minimal effort to recover all your data.

Ok guys. I got that.
Yesterday, I went to one my friends home.
I saw there was 9mb unallocated space in his PC & it is new one.
So, now I just decide to ignore this thing.
Thanx for your replies.
