RAID 0 Recovery possible?

I have a colleague running a older Xserve RAID for graphics storage. Despite the fact that there was no need for the bitrate delivered by RAID 0, some doorknob over there set it up that way instead of RAID 5. They had a drive go red. On a wing and a prayer, we powered down, reseated and got green again, but the array seems to be gone. Not expecting much, we also tried a controller reset and a repair LUN map. I am pretty sure we're hosed. Just looking for anything I might not have tried (besides DriveSavers, etc).
Thanks

Hi Coriolis;
You do have backups?
After years of experience with RAID of all flavors, I feel the most important thing to do with any of them is to set up a good sound backup pocedure. It has been my experience that sooner or later it will happen that the RAID will not protect you from everything kind of failure. This is especially true of RAID 0.

MacBook Pro hard drive failure- data recovery possible?

Hi everyone, I have a June 2009 MBP that stopped turning on the other day and it just sits on a gray screen when trying to boot up. I had it taken in to a small little authorized Apple repair shop since I am living out in BFE and they said it has a hard drive failure which is causing the problems. They said there is no way to recover the data. Is that right? I'd imagine there has to be someway to recover it. Is there somewhere I can send it in or something? At this point even if it were to cost a lot I'd like to get the data off of it if there is the possibility.
Inb4: should've backed it up!

You may be able to boot from an external hard drive and repair the disk enough to copy the data from it, even if it will no longer boot. There are a number of hard drive recovery services. Apple even lists a couple of them (http://support.apple.com/kb/HT3974) that are authorized to recover data from hard drives without voiding the warranty. The warranty is not an issue with a machine from 2009, but those are high quality, reputable companies.
Most such companies have you send them the hard drive and they will give you an estimate of how much it will cost to recover the data, if possible. Some people have reported that Data Rescue 3 comes with a coupon for free diagnostics and $100 off data recovery from The Data Rescue Center. That was a couple of years ago. I don't know if the same deals are in place now.

RAID 1 recovery... stuck!

Hi folks - I installed 2 160g SATA drives (WD ones) a while back and configured them as RAID 1. They've been working away fine for quite a while, but today the machine froze a couple of times and then finally bluescreened on restart - the RAID bios thingy said that the RAID was critical and one of the drives had failed.
What do I do now? It didn't tell me which one - so how do I find out? (I presume it only knows that they are not matching, not which one is corrupted). I was thinkinging I could disconnect each one at a time and do a chkdsk from the recovery console, but It can't see any disks at all...
Luckily I have my laptop, and have been googling, but although there is endless info on setting up RAID, I can't find any information on one to do when it goes wrong....!
Any pointers would be invaluable and v much appreciated...
Thanks, theWoosh
KT400 Ultra motherboard w onboard SATA RAI controller
etc. (cant tell u at the moment!)

Well - the WD diagnostics software fixed some errors on one of the SATA disks (Im not quite sure which one - it said it was EC10 (as opposed to EC00 which tested fine), guess this means it is the second disk and I should be able to figure out which one that is right(?!). Anyway, I dont really know what to do now - I have no log of what the diags did - or if there is a physical error on the disk...
I'm sure there is no problem in theory with rebuilding the array - it is a RAID 1 mirror (and was setup this way for precisely this sort of situation) so the non-faulty drive should have the data intact, Im just a little unclear how to go about it..
I could try to rebuild the RAID array - I thought I could zero the drive that has had a problem (do I need to do this? or can I just use it as it is? Can I use this disk at all, or do I need to replace it?) and then do a rebuild, but I'm slightly worried about doing this (since this disk is at least a partial backup, and Im not sure which disk is which!).
Or I could wait till later when my replacement disk arrives and switch the dodgy one out b4 rebuilding.....
I think I need 2 take a closer look at this b4 doing anything....

RAID 5 recovery

Hi guys.
I have a 7 Disk RAID 5 array that was accidentally deleted in the RAID admin. Two of the disks were not inserted when the deletion occurred. Now those two disks appear as part of an unknown array, and the rest as spares. Is there a way to put the array back together? I am not opposed to putting each disk into a computer and manually editing the partition table or what ever associates the disk with an array.
Thanks,
Bill

There is track information written to the disks. However, it's not user accessible from the RAID. You would have to pull all the drives from the carriers and manually write the info to the drives via some mechanism. And this would require you to know the format of the data.
The only folks who know this information and how to do it are Apple engineering, and data recovery services, to my knowledge. You could try AppleCare and see if they can help -- it's doubtful though. Do you have a backup? A bit late now to remind you that RAID is not a backup

RAID data recovery

Hi to the Forum
Does anybody know if it is possible to recover data from a (Promise) RAID 0 array that has "lost" one of its drives?
If I re-install them on the Intel controller, will I be able to get at the data?
Can I recover the data if they are installed on the standard (non RAID) controller?
HELP..........

afraid not if you loose one drive in rais 0 its all gone

Upgrading Thinkpad W520 CPU and RAID is it possible.

Hello, I have Thinkpad W520. I'm interested two things. First is CPU upgrade. Which is highest CPU for this model? And Can I upgrade to 3rd generation CPU? As I see Ivy Bridge CPU use same socket. Second is RAID. I havent RAID option on my laptop. Is it possible to add this option?And last question I have warranty. Is it possible throught warranty upgrade CPU and setup RAID? Of course not for free.
Solved!
Go to Solution.

AFAIK, you can only upgrade within the Sandy Bridge generation. RAID is integral to the motherboard (you'd have to replace the motherboard with one that has RAID).
I don't think warranty does upgrades.
W520: i7-2720QM, Q2000M at 1080/688/1376, 21GB RAM, 500GB + 750GB HDD, FHD screen
X61T: L7500, 3GB RAM, 500GB HDD, XGA screen, Ultrabase
Y3P: 5Y70, 8GB RAM, 256GB SSD, QHD+ screen

OS on external, internals RAID 0. Possible?

I have a PowerMac G5 that was running 10.4.11. I've removed its hard drives and have put 2 new 750 GB SATA drives in it.
I'd like to put the old drive (containing the OS) into an external firewire enclosure. Then upgrade this disk to Leopard. Then set up the 2 internal 750 GB drives as a RAID 0. Do you think this is possible?
Thanks!

I got a Sumo 320GB instead of the 250 .
Formatted in the way you need to boot in intel-mac. Installed OS X Tiger and it all works perfectly, and there is really no speed difference.
I do have a question, I can not access files from my internal HD now from Tiger. How do i allow Tiger to access my internal Leopard?

W510 BIOS Brick Recovery Possible?

I experienced a BIOS update failure on my Lenovo Thinkpad W510. I've done it dozens of time over the years with no problems, but not this time. I downloaded the BIOS update .iso from Lenovo's website, burned it to a DVD, and rebooted to Flash the update. My battery was fully charged and and my laptop ws mounted on a docking station with a 135Watt AC adapter connected. All seemed to be going well and it told me it had completed successfully but I should reboot with the disc in for further processing. I followed the instructions but after rebooting nothing happened for about an hour. At that point I knew the update had failed. Now, when I power on a few lights flash for a bit, the CD-DVD drive starts up for a few seconds, but the screen remains black and after a while everything goes quiet. My questions are:
1. Is it possible to recover and reflash the BIOS, or should I just:
a. buy a new motherboard,
b. buy a new BIOS chip to replace the dead one on the motherboard, or,
c. use it too replace my broken door stop?
There''s lots of discussion of BIOS recovery techniques on this board and elsewhere around the internet but I haven't yet seen any indication that any of them have worked, and none of them appear to be recent.
Any insight will be appreaciated.
Solved!

Hi Santoku:
Things for your help and suggestions. I've tried the 10xbutton push after shorting the CMOS battery pins early this morning. I'll try it again just for the heck of it. I haven't tried leaving it disconnected for 15 hours but will do so tonight. I saw you were one of the guys trying to help in a similar situation some time ago (2012?). That community member was trying to work with the "Lenovo-Phoenix Crysis" tool to make a bootable USB drive to force a reflash. There was a lot of discussion of .FL1 & .FL2 files and converting one or mor of them to .WPH files for use in the force flash. I didn't really understand all of that and there were obviously large and important steps not discussed.
How does one change a .FL1/.FL2 into a .WPH file? I've managed to extract unpack the contents of the .exe file for BIOS version 1.45 and there are four .FL1 files:
1.in a folder labeled 6LET84WW
a. S01C1100.FL1, and
b. S01C1100.FL1
2. in a folder labeled 6NET84WW
a. S01C1300.FL1, and
b. S01C1300.FL1
I believe the BIOS version for the W510 began with "6N?" so I surmise I should be focusing on the files in folder number 2. Both folders folders had a bunch of files with a .HSH extension. My assumption is that those are "Hash" files to verify the correctnes of various elements of the flash?
Is it possible to recover/reflash my BIOS with the .FL1/.FL2 files above? Do I have to convert them to .WPH files or, as mentioned in some threads, simply rename them. If I have to convert them, what tool do I use? I haven't seen any really good step by step instructions on the web for accomplishing it. Most of the instructions I've seen talk about making "boot floppies" and the tools try to write to drive "A". It's been a long time since I've seen a floppy drive.
Can you shed any light on any of this? Sorry to hit you with all these questions but, to paraphrase Princess Leia, "You're my only hope." :-)

Lion downloaded, started install but said no recovery possible. Now I am stuck what to do?

Managed to download the app but when install was 10 mins in it said that recovery would not be possible and aborted. Any suggestions of what to do?

Macbook Pro hard drive failed, data recovery possible?

Hi everyone,
I have a 13 inch MBP i purchased in 2010. Late last year I experienced some issues with the computer generally slowing down and one day it would not start up, getting to the gray screen with the apple logo and loading wheel. Contacting apple support I was talked through the process of copying my hard drive contents onto an external harddrive, re installing the operating system, and then copying the contents from the external hard drive back to my internal hard drive. Then after up dating the operating system (I think to snow leopard :S) I took it to a genius bar appointment and the guy did a few tests and said my hard drives looks ok and suggested upgrading the RAM from 4gb to 8gb, which I did with no noticable improvement. But seemed to work ok for another 8 months or so.
So last week after using my MBP alot during end of semester, it suddenly turned off while using google sketch up. I tried restarting a few times which did not help. Then I searched through apple support to find an answer. I managed to get into disk utility, which told me the disk was OK. I then tried to re install my operating system which took a very long time and failed twice before getting no response at all I booked another genius bar appointment.
The guy did some tests a very quickly came to the conclusion that it was my hard drive that had failed. He gave me the option to replace the harddrive for $200, which I think I will do, however as STUPIDLY did not have any of my data backed up, I am desperate to try and recover a few important documents and my iphoto library, so have put off replacing the hard drive until I try to recover my data.
So the apple guy gave me two programs to try and recover my data. He said its a confusing an tedious process especially with no experience but I am willing to give it a go. The two programs are DISC WARRIOR and EASEUS. I know disc warrior costs money and easeus is free. He should me how to boot my MBP into target disc mode, and sold me the appropriate cable (initially a firewire cable, but then told me a thunderbolt cable would be more efficient and was cheaper.. Im sure they are right but can anyone confirm that a thunderbolt cable can be used for what I am trying to do) to connect my MBP in target disc mode, to another macbook pro, and it should connect as an external hard drive. Then with one of these programs try to recover some of my files
He said what I can recover just depends on the extent of the damage to the hard drive and what sections have failed. I am waiting for a friend to use their MBP in a few days to download one of these programs and connect my MBP.
Does anyone have any experience or advise with using either of these programs recommended by the apple guy or anyother programs that I could use? Or any advice at all in how I should go about trying to recover my files by using another Macbook pro and target disc mode? or anything else that might be helpful?
ANY help would be much appreciated guys!

Data recovery, possible to get the file structure back as well?

Hi Apple Smarties,
I closed my laptop lid on my external LaCie drive without ejecting the drive first (smart one!). After that the external drive wouldn't mount. I've used Data Rescue 3 to recover all the files from the drive... however it's just lumping all the files into one big batch :-( ...anybody know if it's possible to get the files into the correct files structure they were at before the drive got corrupted?
Assistance would be HUGELY appreciated.
Many thanks
Kind regards
Doug

Thank you Barry. Yes, Comcast is my mail provider. It is a POP account.
Now, if you could point me in the right direction to do that re-build, I would be ever so grateful. I did use the "rebuild" button on the Mail tool bar for that box and it did not help. Perhaps there is something else I could do?
As I mentioned, I am very new to the Mac world, and I get a little lost. Well, at age 73, I guess that's not hard to do! Been on Windows forever so lots of the terminology in Apple is quite different for me.

Loosing everything on a RAID, is it possible in two clicks?

Okay, I TOTALLY screwed up! I hope, beyond hope, someone on here has some magical solution to a total lapse of good judgement on my part. Man, I did the stupidest thing I could manage, I think.
I thought I'd run an erase of my free space on my boot drive, for whatever reason. I have a boot drive, and then four drives connected in a basic striped Raid set (four slices) as my media drive.
I after while I decided to stop the erase operation, as it was taking a long time and the temp file was not letting me carry on with my normal work as it had of course filled my boot drive by this time. I selected cancel (or whatever it says) to stop it, and got the little spinning beach ball. Several minutes later, the ball was still spinning, and so out of impatience I decided to 'Force Quit" the Disk Utility. I think I've tried to do this erase function before and got just as impatient and either force quit it, or the same result occurred maybe my normally let it shut down early.
What happened was it didn't get rid of the temp file and it still showed I had zero space on my boot drive. Having something similar happen, in some fashion, before, I was trying to think how I could now get rid of this temp file. I tried searching for it, but couldn't really find it or know where to look. So I was thinking I'd try to start the erase function again in case it recognized the old temp file as I started the operated and hopefully would delete it.
Here is where I screwed up, totally. Because my drive names are somewhat similar, and because I was a little mentally tired at the time, I inadvertently selected one of my raid slices instead of my boot drive. And in two clicks erased it. I didn't erase the free space, I erased the drive. Or I guess I just reset the table information at the beginning of the drive (I'm hoping this may give me some sort of way out of this mess).
So, in summery, I have three of the four RAID slice images like they were, and the (virtual) raid image is still there (not mountable now), but I have one slice that I erased, or reset as a normal Mac Extended Journaled drive/image.
My problem is that I am a pro photographer (and do some video work) and I had a bunch of things I haven't backed up yet on the media drive and can't replace. I was actually planning on backing them up soon, but what help is planning at this point. I can't tell you how dumb I feel, or i guess numb is a better word.
I noticed a recover file in the trash called "EFTFile1.sparseimage" I'm not sure if that is related, or related to the process of the first erasing process. It is 201.74 GB used. My RAID is made up of 4 X 279.3 drives which was about 1 TB. It was nearly full, so you can imagine how much stuff I had on there. I wanted to back it up, but since I don't have a drive of that size elsewhere I was going to have to be selective about that, which is why I hadn't done it yet. I was trying to pare it down first. My boot drive is 465 GB, and still reads zero space available.
What do you all suggest? Did I just loose tons, and tons of work, some of which I can't recreate again in two clicks? Should I start drinking?
Any help would be VERY APPRECIATED.
Thanks, Craig

Ok, I understand you. Using the show and hide method to dispatch events on the [Component 2], but how can I "reset" for example a comcoBox dataprovider already loaded with data?
Puting on another way:
I have a [products_grid_component] and a [product_details_component]...to go from de grid to the details I wanna use an effect like I explain on my 1st post. I have a comboBox located in the [product_details_compoent] with several options fot that product_id that i'm showing the details.
What happen is, for example, the comboBox's dataprovider is loaded with [Value1][Value2][Value3] and [Value 4] for the product_id=22 (example), when i call the [products_details_component] for the 1st time, I open the comboBox and all the data is displayed correctely with 4 options ([Value1][Value2][Value3] and [Value 4]). Then i go back to [products_grig_component] (both components slides right showing the [products_grid_component] and hidding the [product_details_component]) when i go to [product_details_component] to view the product_id=30, the comboBox behaves like this: imaging that the dataprovides contains [Value 15][Value 16][Value 17][Value 18] and [value 19]...now is the funny part...the comboBox index 0 is [Value 15] but when i open it i can see a space for 4 optnios, a scroolBar and it is still loaded with [Value1][Value2][Value3] and [Value 4] but if i select [Value2] what is going to be displayed is [Value16] and i after i had selected an option, the comboBox shows the optnios correctly..It looks like the comboBox dataprovider is not refreshed.
I already tryed to refresh() the dataprovider, empty the dataPRovider and loaded again with data, etc....but is def something i'm not doing right.
How can i turn around this??

No recovery possible after red_log 100000 and log_archive_format changing

Hello Together,
on a big production database (> 1TB, SAP-System) we passed the number 100000, so we was costrict to set log_archive_format explizit --> log_archive_format = %t_%s <---
Once a month we refresh a preproduction system (it is a job we know well at it is done sapprox 80 - 100 times, no joke, not only this system, but also other systems ;-)).
This was the first refresh after changing that parameter. Now the Refreshed database
(Original Database SID=PCT , rerfreshed also PCT) we are not able to recover.
It is anyway if I give the right archivelog or a wrong one, every time the same error.
Can sombody hel?
Thanks in advance
If you want to phone me, 0049 7633 160 368 I am still trying

TS440 / LSI 9240-8i RAID 5 not possible

Hello,
I´ve received our TS440 with the built in LSI MegaRAID card.
I am able to see all 3 drives - but I am not able to get RAID 5 up and working.
Is this something which has to be licensed first?
Firmware has been updated to the latest one yesterday.

Lenovo Support hasn´t a clue and LSI support did not respond yet.
Thank you!

Hello,
The RAID 500 (LSI 9240) does require a RAID 5 upgrade key to enable RAID 5 functionality.
You can find the upgrade key here. Although the TS440 is not specifically called out, the key is for the RAID 500 (9240) card itself and not machine specific.

2 Drive RAID 0+1 Possible/Worth it?

Hi,
I'm new to the forums and have scanned much of the info on RAIDs yet still remain a little confused. I just received and set up my 2.8 Mac Pro and want to create a better workflow for my graphic design work. I have a 500 Gig boot drive and only want to run apps and os on that. I wanted to add at least two internal drives for client files but wasn't sure if I can set them up for RAID 0+1 with Disk Utility (hope the terminology is correct!) so that I have faster transfer rates along with mirroring. I currently use a simple hardware RAID 1 external box with two 500 Gig drives connected w/FW 800. Seems to be alright and piece of mind but slow every time both drives need to spin up. Do you need to have 4 drives for striping and mirroring or will two work? Will I notice any performance increases with only two drives or should I just run RAID1? How much does having a separate scratch drive help for Photoshop? (That would be a third drive added for scratch if it would help)
I'm set up with an 8 core 2.8 MP with 10 Gigs of RAM running all CS3 apps. (Love the new machine!!)
Thanks in advance for your help and brain power!!

RAID 0 is also known as Striped RAID. This type of array joins two or more drives together to form one large storage space. Data throughput to such an array is usually much faster than the throughput of a single drive.
RAID 1 is known as a Mirrored RAID. This type of array pairs two equally sized drives together such that one drive mirrors the content of the other drive. The total amount of storage is no more than that of a single drive. Throughput may be slightly slower on writes because data must be written twice - once to each drive.
RAID 0+1 (or 1+0) is a combination of the above - two RAID 0 arrays joined into Mirrored array. This arrangement provides the greater storage capacity and speed of the RAID 0 with the failure protection of a Mirrored RAID. It also provides a form of data redundancy when used in a basic data storage setup.
For more on the topic see RAID.

RAID 0 Recovery possible?
