Question

Changed partition size now windows not reporting correct size

Asked by: ajohnpeters

I changed the partition size on an XP boot disk. (I went from a smaller to a larger dis and did a dd copy in linux)

I then increased the partition size and did a chkdsk /r

When I do a properties on C: it says that the disk is the old size.  When I go to to the system administration tools/volume management, the partition is reported as the new larger size.  

When did NTFS and the partition manger get disconnected, and is there any thing I can do to correct.

What are the differing sizes?  Are your disks formatted with FAT32 or NTFS?  Perhaps these two MS articles will be of help:

NTFS,  From looking at the articles I may have a screwed up MFT.  I am defragmenting now.

Also, since the size of the original disk was to small, they had compression on.  I do not know if any of my previous transfers had that.

The partitions manager says the partition is 146 get.  The properties and chkdsk say I have 36 gig.

that looks like that old boundary issue
similar to this

http://mlf.linux.rulez.org/mlf/ezaz/ntfsresize.html#troubleshoot is not opening.  I went to the ntfsreize web page and did not find a good troubleshooting doc.

I believe you are suggesting I re-size the partition again to set the boundaries.  Anyother place for good documentation?

 

by: eviningPosted on 2009-08-12 at 09:35:30ID: 25080352

yes thats what i am suggesting, but im having probs locating any good info on it,
BUT ONLY if u still have the original 36gb drive in case something goes wrong

 

by: ajohnpetersPosted on 2009-08-12 at 09:38:46ID: 25080386

Yes I have the original.

 

by: eviningPosted on 2009-08-12 at 09:50:32ID: 25080486

when u clone, the cloned copy becomes same size as original, then u have to change a few things to recognize extra space, but i forget the exact process, must do a bit of research all over again since last time i turned a 200gb drive into a 10gb drive, lol
u can try a partion tool to just resize tho, since u wont lose ur original 36gb drive

the free version of this should do the trick

I cloned the drive using dd (ddrescue in trinity)  There were 3 patitions on the original drive.

For argument sake (I am too lazy to check precisely) my partitions were 1.4mBytes, 34 g bytes and 2.5 gbytes.

The 2nd part ions was the primary NTFS boot partition.
Tested and booted in WIN XP

I created a new partition at the end of the disk to match the size of the 3rd partition.  I copied the info from the original 3rd partition to the new partition at the end of the drive.

I deleted the original 3rd partition.

Applied the change

Re-sized the NTFS partition from 34 gbytes to 114 gBytes,  Booted windows and it boots
Partition table in Windows and in Linux says the NTFS partition is 144gBytes.  File manager and volume mangers says the NTFS file size is 34Gbytes.

I am going to try to resiz the NTFS partition if I can figure out cylinder boundries.  If that doesn't work, I am going to redo the whole thing.

in ur partition tool can u create a partition with the free space and then merge the 2 partitions?

 

by: eviningPosted on 2009-08-12 at 10:33:57ID: 25080879

gparted should do that fine

 

by: ajohnpetersPosted on 2009-08-12 at 10:34:47ID: 25080888

I have downloaded the windows program and will try,  but I need to check on merging.  I have always deleted and re-sized before

 

by: ajohnpetersPosted on 2009-08-12 at 10:41:03ID: 25080939

I have gpartted abd qtparted.  Inthink  I used gparted on ubuntu.

 

by: ajohnpetersPosted on 2009-08-12 at 10:53:13ID: 31614493

Yes, I had to make sure the boundary was created correctly.  I had to use the tools to put a small unallocated space before and after my boot partition.

The partition-tool. did great.  

Thanks both of you.
