250GB HD shows up in Finder as 128GB

[CrzyCanuck72]

after I entered "sudo pdisk /dev/disk2s10 -dump", it prompted me to enter a password, but it won't allow me to enter anything...no characters are showing up as I type.

The characters don't show. Just type the administrator password blindly.

you have to use /dev/disk2, not the partition device.

 

[CrzyCanuck72]

ok, here we go

Device block size=512, Number of Blocks=488397168 (232.9G)
DeviceType=0x0, DeviceId=0x0
Drivers-
1: 23 @ 64, type=0x1
2: 36 @ 120, type=0xffff
3: 21 @ 176, type=0x701
4: 34 @ 232, type=0xf8ff

232.9G = 232.9GB = the correct size of the drive?

 

[cube]

The line where it says 'Apple_HFS', assuming you formatted as HFS.

sorry, I didn't see the stuff above that

So, it shows a 232.8 GiB partition, so maybe the file system in it was truncated
to 128 GiB.

One would now have to take a look at the file system header with hfsdebug:

[CrzyCanuck72]

oh boy...I downloaded HFSdebug, but could you post detailed instructions on how to "view the file system header." I have no idea how to use Terminal...

 

[cube]

1. Install hfsdebug. Let's do it the fast way: copy just the hfsdebug program to /usr/bin

2. Run hfsdebug in terminal with the raw device of your partition (I don't know your volume name to use the -V option instead):

sudo hfsdebug -v -d /dev/rdisk2s10

At the beginning the size appears.

1. Install hfsdebug. Let's do it the fast way: copy just the hfsdebug program to /usr/bin.

sorry, you lost me here. Where is /usr/bin?

 

[cube]

It's hidden in the desktop. OK, let's do this:

1. Copy all those hfsdebug files to a folder /Applications/Utilities/HFSDebug2.56
2. In the terminal do:

cd /usr/bin
sudo ln -s /Applications/Utilities/HFSDebug2.56/hfsdebug .

 

[CrzyCanuck72]

this is what I'm getting..

CPE000d93699524-CM0013718d2092:/usr/bin username$ cd /usr/bin
CPE000d93699524-CM0013718d2092:/usr/bin username$ sudo ln -s /Applications/Utilities/HFSDebug/hfsdebug .

sudo: hfsdebug: command not found

 

[cube]

Show me:

echo $path
cd /usr/bin
ls -l hfsdebug

 

[CrzyCanuck72]

lrwxr-xr-x   1 root  wheel  41 Aug 13 12:52 hfsdebug -> /Applications/Utilities/HFSDebug/hfsdebug

 

[cube]

And this?

echo $path

 

[CrzyCanuck72]

nothing...

 

[cube]

What about?

echo $PATH

 

[CrzyCanuck72]

gets me:

/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin

 

[cube]

rehash
sudo hfsdebug -v -d /dev/rdisk2s10

 

[CrzyCanuck72]

-bash: rehash: command not found

 

[cube]

OK. Let's just do this:

sudo /usr/bin/hfsdebug -v -d /dev/rdisk2s10

 

[CrzyCanuck72]

sudo: /usr/bin/hfsdebug: command not found

 

[cube]

ls -l /Applications/Utilities/HFSDebug/hfsdebug

 

[CrzyCanuck72]

-rwxr-xr-x   1 danielst  admin  109704 Jun 17 19:25 /Applications/Utilities/HFSDebug/hfsdebug

sorry, the folder had a space in it, I took it out.

 

[cube]

cd /usr/bin
sudo rm hfsdebug
sudo ln -s /Applications/Utilities/HFSDebug/hfsdebug .
sudo hfsdebug -v -d /dev/rdisk2s10

 

[CrzyCanuck72]

nothing...I type it, press Enter, and it goes to the next line with no text or anything...is it processing?
