Is it possible to extend a software raid 0 (built by disk utility)? Let's say I have already a raid 0 with two disks and want to add a third disk.
Is this possible without loosing/evacuating my data?
I have iMac OS X 10.5.8 and would like to upgrade without loosing all the data on my computer.
View 3 Replies View RelatedI recently partitioned my harddrive for windows xp to be installed with bootcamp but now I would rather run VMware fusion. I haven't yet backed up my hard drive. Is there anyway to return to previous settings without losing it all? I have a lot of stuff on my computer is why I ask. Also, if I made a backup of my computer now, will that not work because I am doing so with a partitioned drive?
View 2 Replies View RelatedMy dell computer has recently crashed, so I purchased a Mac mini hoping it would last. Now my problem is that I have to sync my iPad to my new computer, without loosing any data that I have made I have spent over a year using my iPad and would not be a happy camper if I lost my app data and music. So how would you sync it to do that? I know you can do it I have done it before I just forgot how to do it though.

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)
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?
View 3 Replies View RelatedI'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.
View 2 Replies View RelatedI 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?
View 2 Replies View RelatedI 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?

View 2 Replies View RelatedI 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.

View 1 Replies View Relatedive 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?
View 4 Replies View RelatedI 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.

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.
On my 2009 Mac Pro, OS X's disk utility seems to allow the provision of making a mirror RAID or a stripe RAID.
Is it possible to shove in 2 drives, make a RAID 0 for two of them, and then add in 2 more drives to make a RAID 1 out of that RAID 0? (a RAID 0+1?)
I'm having a think about my current backup solution as i've recently got into photography and dont want to loose any of my images. I have a 24" imac with a 640GB Hard drive. I do a Bootable Carbon Copy Clone of this drive after i import any new photos or make any drastic changes to any of my library's to a 320GB WD Passport and take it to my parents. Then connected to a airport extreme i have 2 WD Mybook hard drives. Drive A is 1TB and holds all my master RAW images that are on my imac's HD. It also holds things like personal movies and any other documents that are on the imac. The only thing that it holds that are not backed up anywhere are Movies or TV shows.
Also connected to the AE is a 640GB WD Mybook (Drive B) this is purely for time machine backups. The only issue i can see so far is that the WD passport drive is only 320GB so once my imac drive fills up past the 320GB mark i wont be able to do a CCC backup. I'm currently using about 230GB on my imac so have a little time before i need to upgrade that drive. Now, the imac is in our dining room and my wife does NOT want drives hanging off the imac cluttering the place up, hence the reason why there connected to the AEBS and hidden away in a cupboard... Can anyone suggest any improvements that need to be made to my setup?
I can't figure this out. A few days ago noticed iChat and Mail were not making any sounds when they were supposed to. I double-checked the settings a few times and everything was right, sound events were suppose to take place. I restarted and it resolved the problem.
Now, a few days later, I'm having the same problem.
I wasn't sure where to post this, so I hope this is an okay location.
I recently read that if you open up a jpeg file and then resave it, it loses quality. Is this true?
Is it only Jpegs, or all compressed images? Or even yet, all images i.e. Raw?
What other scenario must I be aware of where file quality can be lost? Any with music files, or video files?

Something seemnd s to be gobbling up about 1Gb in the background this is not visible to Finder/Force quit
