Issue Lacie 2big Raid 0 default settings on mac
Posted: Mon Sep 08, 2014 1:45 am
Hi Everyone,
I recently have and issue with my Lacie 2Big (Raid 0) 2 x 3TB hard-drive.
I think I pulled my thunderbolt plug pre-maturely while I was shutting down my mac (during full shutdown).
Now when I plug my thunderbolt Lacie drive it cannot see my previous Raid 0 partition and it is asking to initialize the drives (like from factory default).
Lacie was not help and I just happen to find R-Studio through google search.
Everything looks so promising when I read the information so I bought the software (last week).
Now I have tried everything and I cannot recover anything.
I used the default Lacie settings for my mac - therefore no changes where done on the disk utility, all I did was plug in the Lacie and initialized it (which Lacie default out of package is Raid 0)
attempt 1:
- create a virtual raid 0
- dragged the first drive volume (not the partition) to the virtual raid 0
- then dragged the second drive volume (not the partition) to virtual raid 0
- I see both hard drive volumes check marked/selected in virtual raid 0
- tried to double click the "Virtual Block Raid 1" (just as explained in the instruction) but it does not see any partition or directory, I just get a message dialog about doing a scan
- then I tried to click Auto detect button on the raid type (as instructed again), but I get another dialog box about needing 3 or more drives (well a raid 0 only needs 2 or more.....)
- then I selected the physical individual drive volumes (not from the virtual raid properties) and did a disk scan on both drives (which took 12 hours for each drive)
- after each drive was done scanning, I saved the scan information and then tried to double click the "Virtual Block Raid 1", still nothing - just the same dialog message about scanning
- so this time I selected the "virtual block raid 1" with the 2 drive selected in the properties box and click scan (software scanned again for another 12 hours)
- oh and I used the default setting of 64 kb for block size, and kept everything else at default as well
- after scanning is done, underneath the "Virtual Block Raid 1" - I see 2 partitions in green (recognized 0 and recognized 1)
- this does not make sense seeing 2 partitions (as it was not specified in the manual what that really means, so I double click the (recognized 0) and I see the directories and files I want to recover
- however, when I goto select the folder and files I want to recover (which is copying to an external usb drive), I see some $catlog errors and I get "The operation was failed error #1001"
- at the time I did not think anything of it, but when I tried to open any of the my files, I get "cannot open files"
attempt 2
- I redid the process of scanning the "virtual block raid 1" but I set the block size to 32 kb (which I saw later on the forum)
- scan took 12 hours with the exact same results
attempt 3 and 4
- I re-did the process of scanning the "vritual block raid 1" using 128 kb and then 256kb (another 24 hours of scanning)
- the 128 kb was the same results as above
- but the 256kb scan I was actually able to see a proper partition name "Lacie" which was the default setup, and again the saw the other partition ( both were green)
- when I tried to recover files, I was able to open up some files (jpg, mp4, mov, mp3) files but they were only partial pictures or video or music.
Which brings me here to this posting - because I keep reading stories about people being able to recover files - and I follow what they did - but with no success
On my Windows and PC and servers, I have not problems with Runtime Software "Get Back Data" and I am usually able to retrieve 80% of the data. So it's not like I haven't done this before.
But for some reason, everything I do on the Lacie to recver does not work and it's not like I have down drive or bad sectors - it just seems like the index tables are lost or damaged.
So what am I missing? Has anyone actually able to recover their files from the Lacie Raid 0 drives with actual working data? It seems like everyone has failed to mention that...
In the manual for the R-Studio for mac, it said that if the picture can only be seen partially then the block sizes are wrong or something like that...
On the last attempt when the setting was scanning with 256 kb block size, it seems like I got closer to recovering since I got the original volume label to show up.
But again, I am completely lost to finding any concrete instructions or guides .... and I have spend the whole week trying to recover with no success, not even a single files was to be recovered...
Any help is greatly appreciated --- because at this point I don't half of the instructions and articles do not match the steps I am following and there are no guides regarding raid 0 scans when you see recognize 0 and recognize 1 (technically shouldn't I only see 1 partition in the raid 0 recovery).
P.S. I also called support at R-Studio for help, I got a brief 1 minute explanation and was told to follow the articles on their website --- and again the steps did not match the results that I was suppose to get.
AM I MISSING SOMETHING ....
