peach-os Posted October 15, 2009 Share Posted October 15, 2009 unfortunately I deleted one of my softraid´s by mistake in disk utilty. of course I did have a backup of the disk but not including my work of the last week if this happens to you or the partition table is damaged for some reason - this guide is a possible solution: 1. don´t try any experiments - you could loose all your data 2. get the recovery tool "r-studio for mac" this app has a possibility to rebuilt the raid as a virtual disk. all you need is to remember the order of the disks and the stripe size you used with this raid before. 3. open r-studio and click on raid in the menu. choose "Virtual Block Raid" 4. choose the 2nd partitions labeled Apple_Raid_offline and drag and drop them in the right order on the new created device. you won´t need the "efi" or the "boot osx" partitions. 5. now you still can change the order of the disks on the right side and apply. 6. define the stripe size and apply. apple default is 32 - if you use the wrong one it will end up with recovered unusable files, but the data on the disks won´t be touched. so it´s possible to try different settings without any further damages. 7. if it worked a new partition will appear - now recover! this way I was able to recover the whole data from the raid 100% - even with names, folders and the complete structure. the price of r-tools is around 80 bucks and was one of my best investments ever! it´s worth every cent Link to comment Share on other sites More sharing options...

Bitplumber Posted April 6, 2012 Share Posted April 6, 2012 I´d like to reanimate this topic. My question to peach-os is what kind of RAID he is talking about. I´m trying to figure out a way to repair a RAID 0 which I accidently resolved via diskutility. The disks are untouched and found by diskutil as follows: diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID_Offline 2.0 TB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_HFS CK 999.9 GB disk1s2 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *2.0 TB disk2 1: EFI 209.7 MB disk2s1 2: Apple_RAID_Offline 2.0 TB disk2s2 3: Apple_Boot Boot OSX 134.2 MB disk2s3 diskutil listraid No AppleRAID sets found The RAID disks are found and marked offline, is there any chance to put them together again or rescue the data as peach-os described?? I tried iPartition (not changing anything on that disks), it even found the Name of the lost volume an its correct size. I appreciate any hint that could help. I asked the german support for r-studio and they said, that r-studio is not capable of repairing RAIDs. I´m a bit confused now.... Link to comment Share on other sites More sharing options...
peach-os Posted April 6, 2012 Author Share Posted April 6, 2012 hahahaaaaa...........how stupid is that ??? that great raid functionality of r-studio was the reason i did spend 70 bucks for it.....wow - great support I had exactly the same situation as you with raid0 - r-studio working 100%. to check that is very easy: the trial version will let you see the files but not recover - just test it. what you need to know is what block size you used - the default is 32 P.S: I speak german if it helps Link to comment Share on other sites More sharing options...
Bitplumber Posted April 6, 2012 Share Posted April 6, 2012 Thanks for replying so fast. My hopes are growing... I will try the r-studio trial version tomorrow and post the result. I would appreciate your help with the upcoming procedure. P.S.: MeinEnglisch ist zwar nicht so schlecht, aber ich freue mich auch auf eine Antwort auf Deutsch. :wink2: Link to comment Share on other sites More sharing options...
Bitplumber Posted April 8, 2012 Share Posted April 8, 2012 Today I tried R-Studio Demo. No matter what block size and number of rows it always finds the same amount of data. It shows the original structure but all indicated original folder files say 0 Bytes. Data files seem to be of correct size. Before I buy the software I would like to be sure not to recover empty files. I tried to add a screenshot here, but it didn´t work. Link to comment Share on other sites More sharing options...
peach-os Posted April 8, 2012 Author Share Posted April 8, 2012 give me some time . I will check that for you with my r-studio version and compare it to the demo. Link to comment Share on other sites More sharing options...

Bitplumber Posted April 22, 2012 Share Posted April 22, 2012 Well, I just purchased R-Studio. I was not able to recover the original folder structure, but a l l f i l e s with original names. I found them in a thousands of numbered folders and it took a couple of hours, but there were no losses. :-)) Thanks again peach-os! I´m still wondering if it´s possible to recover the RAID with its original structure or even "mount" the virtual RAID. Link to comment Share on other sites More sharing options...
