Hardware :: Data On RAID 1 Get Corrupted - Need To Reformat
Jun 24, 2009
Ever since I got this 2TB external (Maxtor Onetouch III RAID 1) I've had it running in it's default RAID 0 set up and it's been fine, however, recently Leopard's been finicky about loading it. (every so often it seems that the data has been corrupted and I have to reformat). I have the equivalent amount of space on other external discs so I haven't lost anything truly important. So that's the situation, here's what I have been thinking about.
I've been thinking of trying to set it up to be RAID 1 so that I can pinpoint whether one of the drives inside if failing or whether I should just try to call Seagate and see if the drive is still under warranty. Does anyone here know the best way to set up this drive to RAID 1? I know I can set up RAID arrays via Disk Utility, but I can't get DU to recognize each drive separately. (setting it to have 2 partitions of equal size doesn't work either, it comes back as RAID failed)
so im looking to buy the unibody macbook...but going to sell this one i ahve now thru craigslist. i have an install disc for leopard if i put that in and do a clean install will this take EVERYTHING off my harddrive...i dont want any sort of personal data to be left on te machine.
- It's on an external hdd, 1tb Western Digital MyBook hooked via firewire. - It's a folder containing music (MP3 + FLAC). - All the data in that folder is gone, 0 file, tried on my Macbook and Windows desktop and both came out with the same result. - External HDD is NTFS, using Paragon NTFS on my Macbook. - The data are still in the hdd, just that it doesn't show any data in the folder, because the space used is still there + the songs still play on my media player library list.
So main problem here is, how what do I need to do to view the data in that folder now.
I have an imac, running 10.4.11. Suddenly I'm having a problem viewing images I've loaded onto the computer. I get the following error - "Couldn't open the file. It may be corrupt or a file format that Preview doesn't recognize." It's very random though. Initially I may be able to view the file (typically a .jpeg), then later I can't, or some of it appears but it's corrupted.
I've tried this using pictures from several different digital cameras/memory cards, so I don't think it's a fault on that end. Also, I've had some problems merely opening up screenshots, and TextEdit files - though again, this seems random. Thinking there might be cache issues, I cleared the history folder, but that didn't help.
Some how through interacting through my iMac file system via PlayStation3 Media Server and my Macbook Pro, the permissions on my Movies folder were what I can only describe as totally nuked and I can no longer access my data. There are no longer any permissions associated with my movies folder in my user's home directory. Accordingly, I cannot access the large volume of movies (all law fully copied from hard copies which I own, of course) via local disk acess or over the network through my Playstation 3 or by mounting my user volume onto my Macbook Pro. I did change the owner via the terminal and the chown command but while the directory comes up when I look at the permissions using root access, when navigating through the finder I still cannot access the data in the folder.
I am using OS X 10.9.4 on a MacBook Pro. When I launch the Calendar app (Version 7.0 (1841.1)), I don't see any of my event. I have to go to the Window menu and click Calendar. The app crashes pretty often. Can I reinstall it without losing my calendar data?
Info: MacBook Pro (13-inch Mid 2012), OS X Mavericks (10.9.4)
My friends iBook hard drive has crashed and I'm in the process of replacing it. However, he had a lot of important data on that hard drive that he needs recovered. Is there any software that you can recommend (for Windows or OS X) that will recover data from corrupt/bad hard drives? I have software for NTFS/FAT32 but don't know of any good ones for HFS.
Every time I sign into my Macbook, I get an error message from Automator; "The data couldn't be read because it has been corrupted.". I have never created an Automator workflow. How do I find out what Automator is trying to run and stop it?
I'm having to bite the bullet on a fresh install, i have already setup a raid in bays 3 and 4. by doing a fresh install will this raid still be recognised by the new os?
I've been trying to migrate data to a new RAID setup, but have been running into the error code 36 issue where Mac created invisible files are killing the file transfers. At any rate, I tried about three different directory cleanup utilities and for the most part got almost all the data to move. Now I'm onto the last bit which was giving me permissions errors as well.I used Batchmod to make everything read write and I ALSO CLEARED THE XTARS. Worked like a charm and everthing transfered. HOWEVER. Killing the extened attributes of the files turned them all into Executible files with no program ownership. BTW, there are font files so there are hundreds of them. Is there anyway to re-assign them or get some of the attributes back?
I have two choices. 1. Apple's Mac Pro RAID Controller, Four Drives, RAID 0+1. One big disk, highest cost. 2. Or, some other RAID Controller (?), Three matching drives, RAID 5. Then, 1 big drive for OS/Applications/Time Machine.
I'd probably move my Home folder to the RAID Array and have just my data striping amongst those drives. Has anyone had a dilemma like this before? I like the idea of hardware separation of my Home folder from the OS.
So right now my current configuration features a 1TB Maxtor Central Axis which houses my iTunes library for streaming to my various computers, devices, PS3, and television. In addition I have a 1TB LaCie hard drive that I use to general backups. I have been considering setting up some sort of RAID configuration to ensure data redundancy while also being able to use the same set up work as a streaming NAS server to my other components. I know Drobo makes a product but it's rather expensive given it's specs.
I have a couple of questions regarding backing up my external drive. I've got a 2TB external drive with about 1.5TB of movies, Music etc. I've got another identical empty drive that I want to keep a backup of the first drive on. So my question is what is the best way of backing up this data? I thought of using disk utility(I'm running snow leopard 10.6.4 if that makes any difference) to created a mirrored RAID set. If I plug in the empty drive then create the RAID set will my first drive get wiped when the set is created? or with it leave the data on the first drive intact? Or should I just use something like crashplan to backup to the 2nd drive?
For the past few months, I've tried to restore my iPod Classic because it randomly restarts itself, not to mention moving on the following song during the middle of a song that is already playing. However, it seems iTunes won't restore it. The following message appears every time I try to do this:

But that website simply doesn't help me out. I've taken my iMac to a Genius and he basically said that something is corrupted in OS X. I should mention the fact that programs such as Onyx and Maintenance claim that I am not the admin when in fact, my account is the only account on the computer. The funny thing was that I created a new account and restored the iPod through there, it would work just fine.
So, besides that long explanation of my problem, is there anyway I can fix this without having to resort to placing all my files on an external and installing a clean copy of OS X? Would archiving and installing back to Leopard do the trick?
I have a single boot disk with just the apps on, and 2 disks in a software mirrored RAID in which I keep all the important stuff.Its just occurred to me, if the boot drive fails won't the software RAID be destroyed as well?Or will it be easy to recover the data off one of the previously RAID1 disks, when the new boot drive is installed?
So I encountered the grey screen with the spinning wheel 2 days ago. I am using a MacBook Pro (Late 2011), I bought it only 2 months ago. I have tried to reset PRAM, booting the computer with; shift, command v, option, command r, command s, and re-installing Lion from Disk Utility. My last and only way out of this seems to be a reformating of the Hard Drive
I have a PowerMac G5 and need to purchase an internal RAID card to create a RAID 1 mirror of the system drive... one that will allow me create a Hardware RAID 1 mirror, not software RAID through OS X.
I just bought a Guardian Maximus RAID1 kit and I have two 1TB drives in it. I'm using it over Airport Extreme as an airdisk (mac osx 10.6.2)
My question is simply: am I running a risk by partitioning it into two partitions? Should I ever have to rebuild the failed disk (which I understand is really simple with the Guardian Maximus) - will it have trouble doing two partitions? I'm using one 500gb partition for time machine and one 500gb partition as redundant itunes/media.
I have a Lacie ext hard drive with 2 x 250gb HD that were one RAIDed into a single 500gb HD. I ran this update Lacie firmware update: http://www.lacie.com/support/drivers...r.htm?id=10053 And now my HD will only show up as two separate HDs of 250gb instead of a single RAID HD of 500gb.
Is it possible to get a highpoint raid controller and put those 4 drives in a raid 5 array (and then create partitions inside that array) - or do you need to have 1 drive by itself for the operating system, and then create a raid array using the remaining 3 drives?
Lastly, are the highpoint 3500 series a decent card? and fully compatible?
I have a new Mac Pro Quad 2.93 with the Mac RAID card installed with four 1TB drives setup in a RAID 5 array. When creating the volumes in the RAID utility, you can not edit them, resize, etc. If one large volume is created in the RAID utility, you can then partition that one volume using the Apple Disk Utility, which then allows you to resize if needed.
I'm using the software RAID right now. Everything is set as RAID 10. I want to move to a RAID card� if I keep it as RAID 10 will I still need to redo everything?
ive put 4 of the hitachi 1tbs in my new mac pro.. and i really want to do Raid on them eventually.. and buy the pricey apple raid card.. i'll do it.. but speed wise:
How fast is a Sata connection straight from HD>Motherboard... ~75mb/s? Is the Raid 5 config with all those drives much faster... around ~110mb/s?
Do you know if there is anyway to get a 5th drive into the raid 5 array? using the ODD space.. or some externals too... i need as much as space as possible...
And boot camp wont work with raid card anymore? I was thinking to have the startup disc be a raptor to increase speed on the apps, how would it integrate with the raid card, etc
I have a RAID 0 set up with two 1.5TB HDs. I am doing some reorganizing and want to take all the data on the RAID 0 and move it to one of the hard drives in the RAID 0 and create to single drives. Is there any way of moving all the data from a RAID 0 onto one of the HDs?
I am planning on getting a 2010 MP when they come and have a question about it. I am 90% sure that with my budget, I will not be able to after a RAID card. I am wondering if software RAID would be alright or if it's so bad it's not worth doing. Also, there is small chance that I could buy a RAID card later on, how would I install it? I will be using it for 3D animation with Maya and some zbrush modeling. Also I will be doing some Photoshop and illustrator and maybe some gaming on win 7 boot camp. Feel free to list any other pros and cons about either a software RAID or hardware RAID, I wana make sure I have all the details before making a final decision on it.
I have never setup RAID before and this question may be totally stupid for that matter.
Can I setup RAID 1 (or call it mirroring) without the RAID card? I have two 1TB internal drives in my Mac Pro and I want to mirror them. I don't want to spend another 700 bucks just to setup a mirror.
Disk Utility shows some RAID options, but I am not sure how to use them, or if they will work at all without the RAID card.
I was working my mac using the terminals. I logged in as root using sudo root, and I changed the permission for /urs folder to 754. I should not have done this but I was intending to change /usr/local/svn. Now all the terminals wont open and after the os crashed I tried to log in but that is not happening either. I have tried to boot in safe mode, it is not helping. I was wondering if any one knows if it is possible to log in as root or system. Because at the moment the only thing that seems to be possible way out is to try and repair the OS with the install disk, which I think is risky.
My friend last night came home with a smile on his face and an iPhone4 in his pocket, he was told to download itunes to sync up and activate his new phone, i told him to wait till I came round but as normal users are he went ahead and downloaded a 400mb upgrade which contained itunes, quicktime and apparently an OS upgrade. Once downloaded he rebooted as told and the upgrade started, once expanded it then complained saying the source was corrupted, reboot to boot the mac... this is where things went downhill.
On reboot he gets a boot failure when the linux part of the OS loads up with a failed boot, all sorted of flags and memory tokens in top left of screen, greyed out and a reboot dialog in the middle of the screen. Macbok is black and the OS i think is ver 9.6(personaly i not worked on macs in nearly 10 years) so am not upto speed on how to fix, repair or reinstal.
As expected, my m8 has no original media, and no backups and is well stuck being completly useless at doing anything right with a computer.
Is there any public shareware tools i can search for and burn to cd so i can boot it up and connect a usb drive to copy the contents off, then somehow repair the OS.
