Can't recover Bootcamp partition  Topic is solved

#1 Postby fkseki » 29 Apr 2012, 05:06

Hi,

I'm on a Mac OS X 10.7.3, using testdisk 6.14-WIP-Intel and I'm unable to recover a Bootcamp partition which I can't boot, I can't see it in Finder but testdisk has it listed and all the files appears to be there.
I'm receiving the message "Partition: write error".

In the beggining it's shown "Write access for this media is not available.
TestDisk won't be able to modify it."

I've tried tried disabling iAntiVirus with no different result.
I've got a few screenshots, testdisk log and rEfit PartitionInspector results:

Re: Can't recover Bootcamp partition

Did you run TestDisk as root, like

Code: Select all

sudo ./testdisk
from its path

Code: Select all

cd ~/Desktop/testdisk-6.14
?
If you have an Intel-Mac you should use partition table type EFI GPT.
Also Info;

Have a retry to see ift it works for you?

I tried doing sudo ./testdisk but it still gives me the "Write access for this media is not available"

I'm choosing partition table type EFI GPT, the only problem seems to be the writing process

thanks

When I tried pdisk, this is what I got...

Code: Select all

sudo pdisk /dev/disk0
pdisk: No valid block 1 on '/dev/disk0'
Edit /dev/disk0 -
Command (? for help): c
No partition map exists
Command (? for help): i
pdisk: can't open file '/dev/disk0' for writing  (Resource busy)


I'm thinking I have to be using a Ubuntu from USB or something like that?

Which one should I try to fix? /dev/disk0 or /dev/rdisk0 ?

Great news!
I've downloaded Ubuntu, put it in a USB drive and used it to restart in it.
In it's terminal I've used parted to write the start and end of the partition I wanted to restore (the numbers I previously got from using TestDisk) and it could write normally! Everything is fine now!

Many thanks, Fiona!

Cheers

Pdisk souldn't be used on an Intel MAC.
Infos from TestDisk Wiki;
Note: pdisk is for the Mac PowerPC partition table, not for the Mac Intel partition table.

Last sentence on this page;

Thanks for your infos that you were able to solve your problem using Ubuntu! :)
I'll set your topic as solved.
