Missing Partition and Unallocated Space (Can't Create New Partition)

Hey there guys. Can you please help me solved this problem. sorry for my bad english.

I'm using Compaq Presario CQ40-627TU

My Laptop Spec

Intel Dual Core Processor T4400 (2.2GHz, 80Mhz FSB,1 MB L2 Cache)

- 2048MB 800MHz DDR2 Memory
- 320GB 7200rpm Hard Disk Drive
- 14.1' TFT WXGA High-Definition widescreen LCD panel with brightview
technology

and i'm using windows 7 Ultimate on boot system partition C, dual boot with linux mint. which mean i got four partition. one for linux mint. one for its swap space. one for windows 7. one for my data storage (movies,drivers,mp3,picture and etc).

last few days i try to resize my C partition (120gb) to make it smaller to gain some unallocated spaces and resize the D partition because my D (almost 100gb) (ntfs/primary/data storage) almost full. i use easeus partition master v5.01.

After done resizing and restart i can't see any D partition. so i was worried that my data will disappeared. i try to look for it but there is no Drive D even on the easeus or diskpart. the only drive appears was C Drive.

i remove my Linux Mint and its swap (60gb) and thinking that i could get some more free space and do some cmd prompt windows 7 repair fixmbr thing to remove the grub. then i use partition recovery to transfer those missing data from partition D to C Drive. (appears as unformatted)

i try to use partition wizard home to resize it back to 300gb. and it works. but i cant make a partition. it will disappear just like that.i also try to use diskpart,command prompt diskpard, and paragon. but also not working. the C drive was shrink but theres no unallocated space and no D drive (the new create partition). i try logical partition,primary,ntfs and fat but also not working. even the unallocated space also gone. i use almost 4 3rd party partitioning software but still got no luck with it.

example:i divide 300gb into 2 partition which exist the C partition 150Gb but the other one gone. i wish theres other way than format. i also done many time. doing check disk, partition table doctor, searching for bad sector. but no errors with my hdd.

Can you help me. sorry for my bad english.Wonders if formatting could help. Thanks. :)

Are you still trying to recovery your deleted partition or data? The tool for this is Paragon Rescue CD. Rescue Kit Free Edition | PARAGON Software Group - free partition software, hard disk partitioning

The tool to use for cleaning HD then partitioning is free Partition Wizard bootable CD. Back up your files, Boot CD, select 1 for screen res, on Disk tab choose Wipe Disk and apply zeroes to HD to wipe the GRUB which will interfere with Win7 install.

Then use PW CD to Create new partitions, Primary for OS and Logical for Data. Install Linux last following this tutorial to Dual Boot with Windows: Where to install ubuntu in my system?

no pal. sorry. i already done delete those linux grub. everything works fine now. but i cant create any partition using 3rd party partitioning software or even diskpart.

the problem now i cant create partition. even logical. when i did that. the partition gone. even when i shrink my C Drive. the unallocated space doesnt appear on diskpart or partitioning software.

now i only have C drive (ntfs/system/boot) only can resize it back to full hdd capacity 298GB.

i cant create one more partition to keep my data files like movies etc. it will disappear when i did so. :)

thanks.

I would run maker's HD diagnostics/repair full CD scan: Hard Drive Diagnostics Tools and Utilities (Storage) - TACKtech Corp.

Have you tried the best Partition Manager for WIn7: free Partition Wizard bootable CD?

i will try the free Partition Wizard bootable CD later because i dont have dvd-rw with me right now. btw my hard disk description WDC WD3200BEKT-60F3T1 ATA Device. Western Digital Brand and i cant see any diagnostics tool for it. It only have Data Lifeguard software. :)

Btw can i use this to make a diagnostic on HDD? Ultimate Boot CD v5.0

For Western Digital, run the Data Lifeguard full scan from CD.

I use GWScan which is Data Lifeguard adapted to work on most makes: GWSCAN 5.12 Unzips to c:cabs where you can burn the ISO to CD.

already done that. quick test and extend test passed. btw i download the ultimate boot cd v5.0 and burn the iso to a disc. i try to create a partition and its work. but when restart i had to wait for checkdisk for unconsistence drive. still wonder why 3rd party partitioning software and diskpart not working lately. anyway, i guess my problem solved. thanks gregrocker. rep up again for you. :)

There is a whole new generation of tools for Win7.

The partitioning manager which works perfectly with Win7 is free Partition Wizard bootable CD.

I would run the System File checker and HD surface test from it first.

Then Wipe Disk with a set of zeros for deepest possible clean.

Then you can Create and format Primary partition(s) for your OS(s), Logical for your data.

gonna try that later. i got no extra data storage to keep my importanat data files for now. thanks pal. :) you helped me a lot.
