Configuring 2 SATA drives for an OS X RAID 1 array & also for OS 9.

Does anyone know if a configuration like this might work in a G4 AGP Graphics "Sawtooth"?
• A SATA controller card that supports RAID 1, such as one of the FirmTek SeriTek cards at the below links:
[http://eshop.macsales.com/item/Firmtek/SATA1V4>
[http://eshop.macsales.com/item/Firmtek/SATA1EVE22>
• Two 500 GB, 640 GB, or 1 TB SATA drives.
• Partitioning 200 GB of each drive for use by OS 9 when booting directly into it.
• Using the two drives in a RAID 1 array when booted into OS X.
• Not installing a 3rd-party RAID software utility for OS 9.
Specifically, does anyone know what would happen when one boots into OS 9? Would the two drives simply be seen as two separate 200 GB partitions?

Hi-
Would the two drives simply be seen as two separate 200 GB partitions?
That is how it should work.
Go one better, and find SoftRAID 2.2 and RAID the 2 200 GB partitions for use in OS 9.

HT201250 Using Time Capsule for Backing Up a RAID Array

I am setting up an 8TB RAID 0 array at home. I am going to use 4 - 2TB FW drives. I already have an SSD in my 3.4 Ghz i7 iMac but am speed hungry and since I have the drives, I figure I would play a bit. I know it is vital to have solid back-up for this, but I am unsure of the best back-up solution. I am wondering if I can attach 3 - 3TB drives to my 1TB Time Capsule and use the combined 10TB in Time Machine to back it up? To date I have backed up each drive separately, but am realizing the folly of that and want to explore RAID 0 at the same time as explore a new back-up solution. Everything I read tells me I need a drive for backing up the RAID array that is at least as large as the combined total of the array. That doesn't make sense if the array is so large... I can't find anywhere if Time Machine supports spanning mulitple back-up drives.

According to the document linked below, you can, but it may not have the performance to back up that much data. Over Wi-Fi, forget it.

HELP ! Two SATA drives in an external enclosure RAID ZERO. Need data recovery.

What a nightmare !     My neighbor died from esophageal cancer and the funeral is in one week. He left behind a G5 2.5 DP tower with a dead motherboard, and he put the two 640 GB SATA drives in an Other World Computing external enclosure Mercury Elite Pro Dual) weeks before he expired. He got access to these drives in this enclosure. (External RAIDs are a no-no).
His grieving wife wants pictures extracted from the drives. There is no known back up and the G5 tower cannot be found.
When connecting the external enclosure by FW800 or USB3, the need to format flag pops up. Disk Utility shows one 1400 GB drive "unformatted".    The DIP switches on the enclosure are set to RAID 0.   Several data recovery programs find files, but of course any jpg over 50kb looks like venetian blinds, Tried Data Rescue 3, and the drive depicted as 1280 GB does not divide using expert features and the command key, thus a RAID SET for emulation cannot be formed. See here: See here: http://www.prosofteng.com/blog/recovering-data-from-a-apple-raid-using-data-resc ue-3-by-prosoft-engineering-2/
What to do now to recover jpg's intact and ASAP ?
1. Try another enclosure ?
2. Insert these drives into my personal G5 tower ?
3. Try different data recovery software ?
4. Which software other than Data Rescue will recover from two drives in one external enclosure believed to be RAID ZERO ?
Thank you.

Yes, if and when the tower can be located and retrieved.   In one communication it was described as a G4, in another, a G5.
Turns out that a single external drive was found, so suspect that is the boot drive. In the mean time, am doing an emulated recovery (two sets) using two converter boxes to isolate the two SATA drives, assuming RAID 0 and 32kb striped,   The two sets and because the drive order is unknown.   The first recovery is almost completed.
BTW, OWC rep stated that the two drives cannot be read in their dual SATA enclosure. The rep stated that the drives would have to be reformatted while in thier enclosure, then use. Tried two enclosures to see if they would read the drives independently, and one brand had a silly interface.   One has to put in two "dummy drives" (or ones in which the data is not important) and then convert the electronics (reset switch + power button) to RAID 0.

Help How to Boot SATA drive? Serial ATA (NOT)- Raid

hi, i have the
Msi K8N Neo Platinum and i despertly tried to boot from the Serial ATA drive.
i have 2 hd in the IDE primary channels
and 2 Cdrw and Cd Rom connected to the IDE Secondary Channels
the Serial ATA is connected to 3 port due to overclocking and msi detecting bug.
the Serial ATA is NTFS and so the Primary Master.
i want to install WINXP on the Serial ATA and so it will boot from it.
i am using the reguler Primary Master for the boot now,, but i really want to boot from the Serial ATA,,
and plz explain me what the hell are those Raid SATA, and all the other types
PATA and stuff.
and do i need to use the driver RAID/SATA diskett from msi?
it's Western Digital 80GB 8mb
plz help

I am having a devil of a time getting my K8N Neo Plat seeing this single drive, and shall try the tricks in the FAQ thread: Single SATA or Multiple Drive Array Setup FAQ
I cannot even format the SATA drive in the MSI - the system locks up, aborts, or I see ASCII characters in the screen after "format terminated" messages. Drive formats fine in my Asus P4P800-E Deluxe.

What Is the Best Raid Array Setup for Photoshop?

I'm considering going to a Raid Array both at the Scractch Disk Level 2X Solid State 90GB Drives, and also at the stroage level 3X Hitachi 2TB HDD.
Which Raid Array setups should I use for each?

Something to consider:
An advantage of RAID 0 is that you get all the space of both drives, while multiplying the throughput.
While RAID 0 also multiplies the possibility of failure, you can offset that by buying high-MTBF enterprise class drives. The Western Digital RE4 is an example (and is the model I use in my RAID). Such drives are not really that much more expensive than their consumer-grade counterparts, and the difference is well worth it, IMO.
Do good backups - e.g., to a large external USB drive (e.g., Western Digital MyBook), and you'll be covered against loss of the entire array.

Alert for failed disc in RAID array

is there a third party software that will alert when a disc in a raid array is degraded or failed? right now, i have to open raid utility to see this. i would like to get a small alert so i can replace the disc quickly.
any ideas welcome.
thanks

SoftRAID http://www.softraid.com
I think there is something like <aa href=http://www.macupdate.com/search.php?arch=all&keywords=RAID&os=macosx> "RAID monitor"
( not rocket science )
Search http://www.macupdate.com
(as well as the usually news, tip, sites) on reports of how well it WORKS and for sending email alerts etc even.
There should be entries in system log of repeated I/O requests and failures, and look for attempts to reassign bad blocks as well.

Expanding Hard Drive Space and Create new RAID arrays

I currently have a 120GB HD that came with computer. I recently installed a new 250GB hard drive to expand my hard drive space. The questions is, can I mirror my current (120GB) hard drive onto the new 250GB drive, install a second 250GB drive, and then create a software RAID with the new drive set, thus creating a 500GB software raid with my the data contained on my old (120GB) hard drive?

Hi subterranean;
Welcome to the Apple Discussion Forums.
If you mirror a 120 GB drive and a 250 GB drive, the result will be equal to the smaller hence you would end up with a 120 GB mirror RAID array.
That doesn't sound to practical to me. Exactly what do you hope to gain here. It might help you to talk about end results rather then solutions. That way we can come up with solutions that will give you the results you are after.

Please help me arrange my hard drive setup, testing out different Raid arrays.

Hi folks! If I could bother you for your time to help me figure out what the best options are for my computer setup that would be much appreciated!! I'm editing mostly RED footage so 5K and 4K files.
Here's what my computer build is right now:
Asus Rampage IV Extreme
i7-3930K CPU (OC'd to 4.4ghz)
64GB ram
GTX 680 video card (2GB model)
Windows 7 Pro
Mostly Premiere CS6 and After Effects
Here's the fun part and the part that I'm still baffled by regardless of how many videos and searches I've done online, what to do with my hard drives!?
Right now I have my Mobo setup in Raid mode with these plugged in to the motherboard;
2 x 250gb Samsung pro SSD's on 6gb/s ports (Raid 0) (Windows 7 OS)
2 x 300gb WD Velociraptors 3gb/s ports (Raid 0) (empty)
3 Ware 9750-8i Raid controller +
8 x 3TB Seagate Barracuda drives ready to rock and roll.
Now based on everything I've read, I'm leaning towards setting up 4 x 3TB drives in Raid0 for my footage (making constant backups with synctoy onto an external Drobo)
4 x 3TB drives in Raid0 for exporting footage. (with continuous backups)
That leaves me wondering where's the best place to setup Media cache, cache files and project files and anything else. Also I've left the OS pagefile on the SSD's but wondering if I should set that up somewhere else?
Using Crystal Disk mark, I'm getting these results so far:
OS on Samsung Pro SSD's in Raid0
The 4 x 3TB drives in various Raid setups:
Raid0
Raid5
Raid10
Velociraptors in Raid0
All this is due to many months of recent work on a computer build that would get bogged down and editing became painfully slow. I'm trying out a proper dedicated Raid card instead of just 2 drives in Raid0 off the motherboard hoping this will make a big difference.
Any expert advice on here would be greatly appreciated!!!!

Let's start with the easy part:
C: SSD for OS, programs & pagefile
D: 2 x Veliciraptor in raid0 for media cache and previews
With 8 disks available on the 3Ware controller you can go many different directions and they depend on your workflow. Let me give two extreme examples and then you may be pointed in the right correction for your editing practice.
Workflow consists of quick and dirty editing, usually one day or less and multiple export formats each day (example Vimeo, YouTube, BDR, DVD and web), or
Workflow consists of extensive editing, usually a week or longer and exports to a few formats at the end of the editing (example BDR and DVD only).
If your typical workflow looks like 1, your idea of two 4x raid0 arrays can work, because the load is rather nicely distributed over the two arrays. Of course the drawback is that there is no redundancy so you depend very much on the backups to your Drobo and restoring data after data loss can be time consuming, coming from the Drobo.
If your workflow looks more like 2, then you can consider one 7x raid5 array for projects and media and a single drive for exports. That means that your raid5 will be noticeably faster then either of the 4x raid0 arrays you considered and offer redundancy as well. As a rough rule of thumb, a 4x disk raid0 will be almost 4 times faster than a single disk, a 7x raid5 will be around 5 - 5.5 times faster than a single disk. You profit from the extra speed during the whole editing week or longer.
The export to a single disk may be somewhat slower, but how long does it take to write say 25 GB to a single disk? Around 160 seconds. If you use a hot swappable drive cage, you can even use multiple export disks, say one for Client A, another one for Client B, etc. In your initial idea of a 4x raid0 that time may be 40 seconds, so you gain around 2 minutes on the export, but lose that in the whole editing week.

Java implementatino for AND-OR trees. And also for its visualization?

Hi,
I need to have an implementation of an AND-OR tree, that is, a tree in which the children of a node can either be conjunctive or disjunctive (normally the parent is consider an AND-node or an OR-node). The reason is that I need to represent Prolog rules in a java structure (not simply as a string). Do you know of any public implementation of such a structure?
In addition, do you know of any existing visualization package or implementation that represents such a structure?
Thank you in advance.
D.

Contact the sales departments of the manufacturers (Giesecke&Devrient (G&D) and Oberthur, and maybe also NXP). They will refer you to the distributor/reseller for your area, through whom you can establish an NDA with the manufacturer and get access to the specification documents.

WinXP-64 bit corrupts existing RAID array

I've got an MSI K8N Neo2 Platinum motherboard running Win XP Pro SP2 on two 36 gig SATA Raptors. Everything was working fine, but I wanted to try the 64 bit version of XP. Grabbed an old 80 gig PATA drive and threw that in the case. Unplugged the SATA drives so as not to risk messing with the existing working OS. Installed the latest 1218 x64 beta and it worked well.
The problem was that when I shut down and reconnected my old RAID array, windows wouldn't boot from it. I lost everything and had to rebuild Windows from scratch. So now I know to never unplug the SATA drives
Rebuilt WinXP on the RAID array and then tried rebooting with the PATA drive with the 64 bit OS. Came up with the "drive needs checking" screen, and proceeds to "fix" the RAID array while ignoring my frantic pounding on the Logitech USB keyboard to stop. Rebooted and yes, the new install was nuked. Okay, since it's gone anyway, reboot to the 64 bit OS and make sure it's got the 64 bit RAID drivers installed.
Reinstall WinXP on the RAID array, reboot to the 64 bit OS on the other drive and the same old scandisk comes and nukes it AGAIN!
So now the PATA drive is sitting on the shelf again, unless someone here can suggest what is causing this problem.
System Specs
Athlon64 3500
gig of PQI 3200 at 2-2-2-5 2.6
2x36 gig Raptors on ports 3-4
Plextor PX-716a DVD+_RW
Visiontek X800 Pro.

The first time you re-installed Win 32 on the raid that was a bit drastic. A repair ought to have done the job.
The problem was probably that you disconnected the array but that's where the boot.ini was and that file needed to be modified to add the path to the Win64 install.
Since you took out the array the Win64 install created a new boot.ini on the PATA drive. Even when you tell BIOS to boot off the array, Windows has a bad habit of looking at the IDE channels & using the boot.ini if it finds one there - but the file it found didn't point to the array of course.
So basically if you already have Win32 on the array I would leave that array connected normally when installing Win64 on the PATA drive and all should be well.
I've installed Win64 on the same array as my Win32 install and they co-exist happily. I reckon that's the most efficient way to do it. The main thing is to make separate partitions for Win32, Win64 and data files when you install Win32 in the first place. The two OSs can share the same data files, incuding stuff like email.

K8MM-V - how to get sata drive working in bios

Hi,
I've attached a maxtor diamondmax plus 9 160GB sata drive to the pc now. On chip SATA is enabled. I get a message at staet up that I should press tab to enter setup. I do that.. Then I get a message that I only have one sata drive and therefore cannot create RAID. There are other options but I cannot enter anyof them (the create / delete array stuff on the left is dark blue). I can't even view status, or confirm any choice (or select any choice). It does show my sata drive below on Serial_CH0. But there is no array name (as I haven't been able to create one). Do I have to set the drive jumper settings or something? I don't know what's going on.. Also.. I ran the maxtor tools cd.. it didn't pick up the drive. Someone please help.
Thanks,

You don't need to define an array, just install windows on it (use the driver disk too)
With 1 drive connected, it's working like a normal SATA controller.
I have the same here, you don't need to configure anything.
Except for maybe the boot-order in the BIOS, mine has two types of orders.
For the Harddisk you should have something like:
1st Floppy -> 2nd CDrom -> 3th HD-0 or IDE-0 (whatever try call it in there)
Then you look at the Harddisk Boot priority, where is should say something like Sata-disk and second addin-card.
Not sure if your BIOS is the same, but that's how it works here.
Basicaly, if you have no PATA IDE drive's connected it should work by just connecting the drive.
And yes, the BIOS will continiu to mention there is no raid, don't bother about that as a single drive can't be a raid.

Memory errors after Array is created SATA drive

Hello,
I am trying to setup a 655 Max board with a SATA drive. Once I define an array, I get Memory errors. I am testing this using the Microsoft memory dest boot CD. As soon as I delete the array from the drive, the memory test is able to work sucessfully. I am using FASTtrack with a promise 376 driver.
Brian

I have been searching the forum for links between raid array's and memory issues. I noticed some people that have random stop errors when loading xp (which is what I was also seeing).
Why would the promise (raid controller) have an effect on the system (ram) like that? I noticed as I ran the Microsoft memory test, it would start to get all garbled on the screen and every once in a while information would show up from the fast track screen. Hmmmm....

SATA drive support?

I would like to add some SATA drives to my G4 as a backup scheme for Retrospect. What PCI controller should I get that works with Mac OS 9.2.2?
Or is there a Firewire (1394A) solution that I should consider?
Gary

>If it were my machine, I'd stick with firewire.
Me too. But I need the large capacity offered by SATA. I have a small army of 500 GB IDE disks and they are taking up a lot of desk space.
My ideal system would have a single Firewire dock with 1 or 2 bays in it populated with 1 TB disks. I can't find any vendors that make (or made) 1 TB IDE drives. Thus my desire for SATA.
Your thiughts please.

RAID array activation issue in CS2 & XP

Yes, I still have CS2, which I love, as well as Production Studio. I have used CS2 for years with a RAID array, first striped and now a mirror. The mirror array lasted about 10 months until the motherboard went. eVGA replaced the motherboard with the same model, I fiddled around a bit trying to get my same array up and running, I couldn't figure it out and ended up doing a reinstall (after a couple of weeks of running single drives). Anyway, I keep having to activate my Adobe Suites. I have talked to people (thick accents, maybe in India) three times now; takes a lot of time. I know that there is an issue with CS2 and RAID (XP and CS2 have all of their available updates). I tell them I have RAID. I ask for a patch to avoid the activation issue. I have been told that I "should not be using RAID", that I will "have to reactivate every time I boot" and that I won't be able to run this "without upgrading to CS4". I KNOW that this configuration will work, because it has worked in the past. I vaguely remember a patch when I originally installed.
I just called the Tech Support number, instead of the activation number. I also got someone with a thick accent who told me that he had no support available for CS2. He wouldn't give me a phone number to call, I asked about a patch and he "doesn't support CS2", end of discussion. He suggested the website. Ugh!
I am not locked out at this time, but have just done another reactivation. I suspect Adobe will put a stop to repeat activations. I worry about being locked out when I am under the gun trying to finish something. My son is working on a school project for the end of year right now. What can I do? Does anyone know where I can find a patch or talk to someone who will help a CS2 user?
I LIKE my RAID array. I know that my data is perfectly backed up at all times. I would prefer not to have to break the RAID array into single drives. I chose this MB because of the RAID capability.
Thanks in advance!

Thanks Bob. I asked to speak to a supervisor with calls two and three to India, or wherever. One lady said they didn't have a supervisor and then said, well, of course we have supervisors, but they will not be able to help. I guess I could have thrown a fit, but neither was willing to connect me to a supervisor even though I asked. I did find it amusing (in a sad way) that the one lady initially denied that she had a supervisor.
I then called Customer Support (call number four) and they simply wouldn't talk to me. They don't deal with CS2, didn't want to talk to me at all.
I guess I'll try India again, next time it locks me out.
I'll go through old files (again) to see if I saved some kind of patch.
Thanks again.

Xsan 2.3 qualified RAID Arrays

Hi there - I've been searching for documentation on "qualified RAID arrays" to work with the new Xsan 2.3 in lion. As Apple says in their release of lion that "Lion also supports industry-standard multipathing and failover, so Xsan can be used with a variety of Fibre Channel RAID storage arrays." (http://www.apple.com/macosx/server/) at the bottom. I pulled up mr. Manual and searched "qualified RAID Arrays" and I get to the section in chapter 3 "Supported Storage devices", and warned to make sure to use only an apple certified RAID array... For the latest information see www.apple.com/xsan/
So I click there... and it still only has the Promise Vtrak system labeled that was supported in v2.2.... Anybody had any luck finding a list of other supported arrays? Anybody currently running any other fibre arrays?
Would love to know! Thanks Everybody!
Kyle

Well and it's not to say that the Promise's are bad - that's not what I'm saying at all, I just want the option. I'm just looking for other people that either have done the same research I'm doing - or are personally using a different array. There are many other arrays out there that are just as reliable and fast that have a much nicer price tag than Promise's stuff. Currently we are living off of 3 XserveRAID arrays, which is fast enough for our 3 workstations. But we're looking to add 5 more (1 final cut and 4 animation stations using AE and Maya/nuke). We are running an OLLldddd Xsan version (like 1.4.2 maybe?? don't have it in front of me) but Everything is needing a giant face lift... and with each lion box allowed to use Xsan the only thing holding us back is After Effects being compatible with Lion. Maya and nuke boxes actually can use AFP to get to the SAN and would be fine.
Anyways. I'll give you credit for a helpful answer - but I'm looking for more concrete choices
Thanks
