Problem while creating new partition on hard disk.

[rocker07]

First sorry for bad english.
I am using Hitachi hard disk (Hitachi HDS721050CLA SCSI Disk Device) which has actual size of 466 GB, on windows 7. When i assembled PC from retailer he made three partitions of size C=151, D=152, E=162 GB. I had no idea about partitions at that time.
Now I understand that making more partitions will be useful for data management so I moved all my important data to E drive. And as my system was slow i also wanted format windows 7.

While formatting i deleted C drive(System) and D drive(which was labelled as logical), which Created about 300 GB free space. First I created 1 drive with size of 120 GB. while creating this drive windows pop up with message saying something like this, 'For security reasons windows will create one additional drive".So It created two drives , one with 120 GB and second with 100 GB.It Still shows 183 GB free space was left. I created one extra drive with 90 GB space. After creating this drive 93 GB free space was left on hard disk. But there was no option to make additional drive. So i completed format and re-installed windows 7.


Now i have three drives, Newly created C=120, D=90 and old E=162 GB plus 93 GB free space. When computer restart after format, it open D drive in auto-play menu like DVD, which was totally unusual for me and it even ask me to format it.
Now the problem is i want to create new partition from with that 93 GB free space. So i opened disk management tool. Then while creating a new simple volume at unallocate space i have this message before creating

"the operation you selected will convert the selected basic disk to dynamic disk,if you convert the disk to dynamic you will not be able to start installed OS from any volume(expect the current boot volume).

Does something wrong is happening with me, some users are saying that this will destroy hard disk. My PC is just one year old. So i simply cant buy new hard disk. Should i proceed or better loose my valuable 93 GB space.

Creating a Dynamic disk will delete all the data on all the remaining partitions. The Windows 7 OS will remain intact.
This procedure only destroys data, not the physical drive.

There's free partitioning software that will allow you to increase the partition(s) sizes, to utilize the 93GB.

Creating a Dynamic disk will delete all the data on all the partitions, other than the OS partition. You're probably better off using a partitioning software to increase the size on one of the partitions.

Thanks for reply. I will try to do that. But i have still concerned about D drive auto-play and asking for format. though this happen only once, Thus this mean that my hard disk is damaged.
I have lot of bad memories regarding USB pen drive for same problem. when pen drive is useless it give same error when attached to PC. It work good until i move data in it and when i again connect it to other or same pc, it always ask for format.

Do not say yes to dynamic disks. They are a major problem.

4 or 5 partitions is not the most efficient way to manage data. Folders are much better.

The problem with 4 or 5 partitions is that you can't accurately guess how quickly each will fill up and you will run out of space sooner than planned in at least one of the partitions.

If I were you, I would use 3 partitions: the very small 100 MB system partition, C for Windows, and D for all data. Use a series of folders on D to manage data.

I'd temporarily move all data now on E to C and D. Then delete E.

Then expand D to make it much larger, using all of the unallocated space, including the space formerly occupied by E.

Then move any data temporarily on C back to D.

You could also make C smaller than it is now and add that space to D also. A C partition of 80 or 100 GB is plenty for most installations.

You can do all of that with Partition Wizard as mentioned by Sardonicus. Make sure you get the bootable version and burn it to a disc.

If you think your hard drive is damaged, you should run the drive manufacturer's downloadable testing utility.

The problem has solved with EaseUs partition manger home. I created c=120 GB, D and G both logical of 90 GB. and kept E(primary) with 162 GB.
Now the problem remains of hard disk damage. I noticed lots of videos on hard drive got corrupted. Sometimes my songs are also missing. Though there are various reasons for this, does this is because hard disk damage.
I searched Hitachi website but i cant find my hard disk name. I used crystal disk info which was recommended on various sites for hard disk health information. That gives me horrible results. can someone give me more information regarding this issue.

Your reallocated sector count is shaky.

That means that portions of your drive have gone bad. The normal course of events is that more and more of it will go bad over time.

I'd start shopping for a new drive, but you might want to run a drive utility from Hitachi for confirmation.

Will this issue will cover under warranty. Hitachi provides three years warranty , that means still 1 1/2 year still left. I had previously 488 GB available space but now only 466 GB available. That means already i have lost 22 GB in 1 1/2 year. Is this normal?
Here is one another screenshot.

The actual usable space on a hard drive is about 93% of the advertised space. 93% of 500 is 465, which is within 1 GB of the actual usable space I would expect to see on your hard drive. I'm not sure where you got the 488 GB number.

You should run a Hitachi drive utility test on the drive. If it fails the test, you may have a warranty claim.

That HDD Tune picture doesn't tell me much. The access time of 20.6 looks a bit high (slow).
