Norton Partition Magic (cannot acces to partition)

Few days ago i used Norton Partition Magic to expand (C:) partition taking 10 GB form (D:) partition.
After reboot under the processing that,in company was a power failure.
Now we cant access to (D:) it constantly asks to enter disk into drive D
As we dont have Diskett drive we coudnt create a resque diskette.
Formating that partition is not an option,because of data loss.
We found that data is still on it,but we cannot access it.

Thanks!

Hi Catastross,

Welcome to Norton Community!!!

One reason for inaccessibility of D: drive is that it does not have drive letter assigned. You can assign drive letter either in Partition Magic or in Windows Disk Management.

In Windows Disk Management, right-click the partition which is not having the drive letter, and then click Change Drive Letter and Paths. Click Add, Click Assign the following drive letter. Select the drive letter you want to assign.

Similar options you will find in Partition Magic to assign drive letter.

Re: Norton Partition Magic (cannot acces to partition)

We tryied to set a drive letter using Disk Management and there is no highlited option exept Delete Partition and Help,so we tryied assign with Partition Magic.

The problem is when we try to run it,Installer shows up with a message:

Error  1324. The path program files contains an invalid character.

We succeeded to open Partition M.

After changing Drive letter,we start the proccess and in about 90% of procces we got:

Error #702

Hi Catastross,

Try Diskpart utility in XP to assign drive letter.

1. To start Diskpart, go to Command Prompt, type the following and press Enter:

diskpart

2. At the DISKPART prompt, type:
list volume

Make note of the number of the simple volume whose drive letter you want to assign.

3. At the DISKPART prompt, type:
select volume n

Select the volume, where n is the volume's number, whose drive letter you want to assign, change, or remove.

4. At the DISKPART prompt, type one of the following:
assign letter=D
Where D is the drive letter you want to assign.

We dont have an option to assign letter to a missing partition.

Re: Norton Partition Magic (cannot acces to partition)

Can you get the data off the partition by using BartPE? Maybe the partition will be assigned a drive letter in BartPE.

we gotta try that,thanks for advice.

Re: Norton Partition Magic (cannot acces to partition)

I note your second partition is "System" indicating it contains boot files. Have you been dual booting? Do you have boot files in your first partition? (boot.ini, ntldr, ntdetect.com). You will have to Show hidden files and folders as well as remove the tick from Hide protected operating system files.

Being a System volume is probably preventing you from assigning a drive letter.

Re: Norton Partition Magic (cannot acces to partition)

i found the ntldr, ntdetect

in C:

Could you explain how to remove it,an will removal affect of curent win. system?

Re: Norton Partition Magic (cannot acces to partition)

Did you find boot.ini? Are you dual booting? Does that partition get a drive letter in BartPE?

Maybe the corrupt partition is giving a false "System" status but you don't want to delete that partition until you are sure your C: drive will boot on its own.

Re: Norton Partition Magic (cannot acces to partition)

A power loss is usually why we recommend backing up before performing an action in Partition Magic.  That said, you can try the following:

Launch Partition Magic with the /IPE switch. 

Attempt to resize the D partition by a very small amount (say one cylinder).

Apply the operation.

Partition Magic has some ability to pick up and figure out what the valid file structure information should be, but there are limitations to this depending on what was occuring the moment the power failure occured.  If this does not work you may need to use a disk recovery tool/service to get the data back.

tryed but its not given an option to resize it,only to delete it!

Re: Norton Partition Magic (cannot acces to partition)

Unfortunately this is in a worst case scenario.  If you cannot resize with the switch then we're beyond recovering the partition.  If there is important data, I'd recommend using a data recovery program to grab the data off before deleting and creating a new partition.

Re: Norton Partition Magic (cannot acces to partition)

Maybe a bit late respons:

On the Cd UBCD is a program FixMBR. After trying a few options I got my partion back.

(PartitionMagis had its properties changed to WIN95: extended partition LBA-mapped)

The strange thing is that I didn't do anything with this partition, I tried to merge two other partitions.

I hope its still helpfull for somebody, maybe Norton can fix the bug in PM (it must be a bug. . .)

Re: Norton Partition Magic (cannot acces to partition)

I may be able to offer some advice in this.  Depending on where the power interuption occured during your process there are few things that can be attempted.  First when you first checked on the partition after the power failure did it show a file system of 3C or say PQ Recovery Partition anywere on the visual display of your D: partition?  This is the normal state that PartitionMagic leaves the system in after such a failure to protect the partition from other programs trying to "fix" it.

Please read this entire post before you start you should begin with the option you feel most comfortable performing, both technically and in risk.

One thing that can be tried but it does pose the risk of potentially making the issue worse.  However I've seen this to normally be quite successful.  That is to run PMAGICNT.EXE from a command line using the /IPE (this is one of those switches that you should only use with a qualified technician, so the rest of you out there don't play with it, or you will likely get burned) switch and resize the partition down by just one cylinder (as little as possible in other words).  This will generally force PartitionMagic to try and pull all the pieces back together again.  If this works you can then resize it back up (running without the /IPE switch) to it's full size and proceed normally.

The next one is a bit more technical but actually safer that the first option.  For this you need to run the utility that comes with PartitionMagic called PTEDIT.EXE  This is a fairly simplified partition editor.  When you open this program you will see 4 rows and several columns.  The first two will have numbers in them and the last two wont.  Look in the far right column (NumSectors) and find the entry with the largest number.  This is the partition you are trying to access.  Write down all of the values in this row so that we can put them back if needed.  After writting them all down zero the values in that row (and just that row).  Exit PTEdit (it will prompt you to save the changes, do so).   Now go into PartitionMagic and you will see unallocated space where that partition used to be (it will appear to be gone).  At this time use the PartitionMagic Undelete Partition feature.  It should hopefully give you at least two potential partitions to recover.  One should have dimensions equalling the current size, the other should have dimensions equalling the way it was before you started the process in the first place.  Choose the one with your previous values to do the partition undelete.  Check after this is complete to see if you have access to your data.  If you do, your fine.  If this one concerns you, you may want to be on the phone with one of our Symantec's technicians when you do this.  But in truth there isn't much risk you can always open PTEdit back up and restore the values you wrote down and be back to square one.

Just to explain what has happened, when PM was rearranging your data it got interupted at a point when it was readdressing your file structures.  So your system shows the new larger partition, but the file structures had not yet been moved from their original location to the new one, so it can't see your files.

The last resort would be to use some data recovery software, which if it comes to this should be very successful as the files are all there, they just aren't addressable by the system in their current state.
