Recovery from GPT Protective Partition

[fackeid]

Hi friends
I have one Hard drive 1TB (I Omega Drive) which was used for Mac machine. When i connect it to the windows XP machine in the Disk Management it shows me - GPT Protective Partition.
Now from one website i tried to convert it into MBR style partition format using following commands
CMD => Diskpark => Selecting proper drive and then Clean and after this Exit
(Please note - all bold letters are commands)

So I got this hdd ready to get Initialized, i tried for it and now in XP i can see the Unallocated space.
Now as per my knowledge if i try to Create partition in above Unallocated space then i might get my data lost.

I tried to pass this drive to PTTD partition manager but it could not locate the partition structure also i tried to pass drive to Active File Recovery.. it also did not help me.


Please someone guide me for further issues.. I want to recover data back...

Well, your first problem is that XP isn't going to recognize your HFS+ partition

Your second problem is that you can't just erase the partition table and then expect XP to know what it is looking for

Hi
I am aware what i did but now how to recover the data back?

Because i guess many data recovery software can recover the data from completely damaged partition structures as well.
They simply can bypass the partition table restrictions.

Now please guide me further.

Oh god. Converted to MBR. i dont think you can get your data back now.
If it was ext2/3 then still have luck if it was HSF+ ; then you wiped the whole structure of the files (so called journals) and its hell rebuilding the file structure.
This is a problem also if you have bad secotrs on the HSF journaling sectors- because it cannot read past the bad sector and cannot rebuilt the tree.
Or am i mistaking with another Filesystem?
You can try rstudio i suppose. But you just made your situation so BAD

Why did you not jsut use your macintosh to copy the files?

Take it to a pro. You are a danger to your data.

If you just ran clean from diskpart (and NOT clean all)
then all you have done is zeroed the first sector on the drive

Then Initialize will just set up an MBR and empty partition table on the first sector

All the previous data area sectors should be untouched
so a data recover scanning tool, that understands Mac / HFS structures should be able to recover it

Hopefully - if thats all that was done.

通过修改分区格式，可以把GPT分区显示为MBR格式。初始化的后果，是修改了0#扇区，并写入了windows引导程序。如果是这样的操作，那么影响是很小的，大约是513个字节（MBR512字节加上GPT转到MBR分区标记1个字节），数据的破坏是比较小的，可以恢复。

R-Studio will do the job, optimistic

By modifying the partition format that can be displayed for the MBR to GPT partition format. Initialization effect is a modification of the 0 # sectors, and write the windows boot process. If this is the operation, then the effect is very small, about 513 bytes (MBR512 MBR to GPT partition bytes plus 1 byte tag), data destruction is relatively small, can be restored.

You can obviously read the posts here in English, so whats so difficult with replying in English also?

Thanks for all your valuable feedback, I am also thinking on this overwritten only FEW sectors, and there must be complete data available on the disk.
Let us see what the R-studio shows me.

thank you once again for absolutely valuable responses.
