CD rom and Raid

i jus got my second raptor HD today and tried to setup a raid 0 on my computer. I got the raid utility to work and created the array. I have two raptor 36gs on sata 3 and sata 4 and my cdrom on IDE1 master. When i start up it does not detect the cdrom drive and i cannot boot into the windows xp cd. Is there somethin g i'm missing here? thanks

Spunky,
That is really a loaded question, because my recommendation on that would depend on the motherboard you are purchasing.
What you need to look at is what version of SATA Drives you will be using, how many drives you will want in your array and the type of array. Therefore, what you need to do is write that down including what motherboard you are going to be using. Then, determine which RAID controller will do the job. If you would like me to help do that then, post the information and I will help you.
As for speed you will have to run diagnostic software to see which one is fastest of the two, but in general use, unless you programs demands the fastest possible mass storage data transfer rates, you will not notice any difference between the two.
Now that, that has been said, if you look at my signature you will notices I use RAID Arrays and I do not use either Silicon Image or the nVidia RAID Controller. If you interested in that, let me know and I will discuss it with you.

When submitting a problem, include a complete list of your system components; include part numbers, all Power Supply Voltages, and their output ratings. It is almost impossible to estimate what your problem is without knowing something about it.

I will be traveling to Rome and Paris. I'm concerned about frying my IPad when charging the battery. Will I need a converter/adapter to charge the battery or do I just need an adapter.

what RBRY says. Look at the fine print on your power brick. It says 100v-240v. This means it can handle world wattage.....both the us 110 and the UK/and other places 220. Anything that displays that range works anywhere in the world with the right plug adapter.
You can get plug adapters at walgreens, walmart, target, kmart, best buy, office max, office depot.....almost any major retailer. Look in the travel/luggage area.
Do some googling and find out what Italian plugs look like or you can simply find a kit that is a 'world wide' kit.

Advice on RAID Sets, Volume Sets, and RAID Levels of the Volume Sets using an Areca Controller

I have read through a lot of information on disk usage, storage rules for an editing rig, users inquiries/member responses in this forum and I thank each and every one of you – especially Harm.
In building my new workstation, I purchased five (5) WD 1T, 7k, 64M SATAIII hard drives and an Areca RAID card, ARC-1880ix-16-4G, which I plan to use primarily as my media/data disk array. The workstation will use a 128GB SATAIII SSD as the OS/program drive and I will transfer two (2) WD Raptor/10k SATA 70GB drives from my current system for pagefile/scratch/render use. I tentatively plan on using a mobo SATAIII port for the SSD and mobo SATA ports with a software RAID (level 0) for the 10k Raptors.
In reading the Areca Instruction manual, I am now considering exactly how I should configure the 5 physical 1TB drives in terms of RAID Level(s), Volume Sets, and RAID Sets. I must admit that I like the opportunity of allowing for a Dedicated Hot Spare as I am generally distrustful of the MTBF data that drive vendors tout and have the bad experience in the past of losing data from a mal-configured RAID array and a single drive hardware failure (admittedly, my fault!).
In line with the logic that one doesn’t want to perform disk reading while trying to write at the same time (or vice-versa), I am thinking the approach above should work OK in using the mobo disk interface and both software and external hardware RAID controllers without having to create separate RAID level configurations within a Volume Set or further dividing up the physical drives into separate RAID sets. I know in forum messages that Harm noted that he had 17 drives and I could envision a benefit to having separate RAID sets in that situation, but I am not at that point yet.
To some degree I think it might be best to just create one RAID Level on one Volume Set on one RAID Set, but want to solicit thoughts from veteran controller users on their workflows/thoughts in these regards.
Anyone care to share thoughts/perspectives? Thanks
Bill

Thanks for the speedy feedback Harm - I appreciate it.
I was thinking RAID level 3 as well.
Of course, it's always something! I purchased the Caviar Blacks by mistake - which are non-TLER. I will work with EggHead to return the ones I purchased and replace them with RE4 versions as I'm not thrilled about the possibility of the controller declaring the volume/disks degraded unnecessarily and although I have the DOS utility WDTLER where one is supposed to be able to enable/disable TLER on WD drives - I suspect WD is way beyond that now anyway with current builds.
I agree with you about just testing the performance of the options for the raptors - on the mobo and then on the controller. When I benchmark them I'll post the results in case others are curious.
Thanks again....off to EggHead!

Windows 8 and Raid 5 (English)

Looking for confirmation that Windows 8 does not have the ability to use Raid 5 even if it is presented a single logical drive by a controller.
I have a SABERTOOTH 990FX R2.0 that makes a drive. All the docs say Raid 0 and Raid 1.
The Windows 8 and Raid 5 question already posted looks to be in Spanish.
With regards,
Quentin L. McCallum, CISSP

Software RAID 5 is not supported on Windows 8. You can use Storage Pool.

How to install the driver of the 'SCSI and RAID Host Controller'

Hi,
I have two Windows XP(32Bit) installations:
•Windows XP SP2(32Bit) which is old and it seems as if it is infected by some viruses.
•I have installed another fresh clean Windows XP(32Bit) SP3. However, I have found that there is no category named with ''SCSI and RAID Host Controller'. However, when checking out the old version of Windows XP, I found 'SCSI and RAID Host Controller'
is there. (Screen shot below)
The new Windows XP(32Bit) SP3, there is no 'SCSI and RAID Host Controller'
My motherboard is:
My Desktop Computer(Intel P 4, 512MB of RAM, and Graphics Card with 256MB of RAM.
]I am seeing that most computer doesn't has the scsi / raid controller . in the old Windows XP on my computer that SCSI and RAID controller exists, and it it has not a yellow mark on it.
When I installed a new windwos XP 32Bit SP3, no SCSI/RAID in divice manager .
My computer sound on new Windows XP doesn't work , however, on old Windows XP SP2 works well. I have a buitl-in sound card. SCSI and RAID controller category in the device manager on the old Windows xp SP2 is realted to sound card,I don't think.
Thus, What drivers would let the 'SCSI and RAID Host Controller' added in the device manager?
A man should convert his anger and sadness into strength to continue living in this life.

If you open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on the pcb somewhere. You should also normally see this information on the first POST screen when you turn on the PC.
Otherwise Google "775i65G" like I did.
Here are the driver downloads (assuming it is an Asrock 775i65G R2.0 and not an R3.0)
http://www.asrock.com/mb/Intel/775i65G%20R2.0/?cat=Download&os=XP
You should install the inf driver first. Hopefully after you do that you will see your desired listing in Device Manager.
With regard to the AMR driver and the HDMR driver, you can find some information about these here :
http://en.wikipedia.org/wiki/Audio/modem_riser
Unless you actually have something plugged into these risers, it is probably not necessary to install the drivers.
However, the drivers for the integrated C-Media audio chip and the Realtek Lan chip may prove useful.
It looks like the motherboard has integrated video but if you are using a graphics card it will not normally be necessary to install the VGA driver.
You can download both the manual and the installation guide here
http://www.asrock.com/mb/Intel/775i65G/?cat=Manual
And if "SCSI and RAID Host Controller" is still not shown in Device Manager, don't worry - because these functions are not supported by your motherboard (again assuming it is an Asrock 775i65G)
Thanks a lot,
First of all, when saying that I have multi-operationgs systems, I mean there are two operating systems installed on my PC(SP2, SP3) both are 32Bit. The first Windows SP2(NOT installed by me) has all multimedia audio card installed
well, and has SCSI and RAID Host Controller shown the device manager. However, only the VGA is not installed on Windows SP2. However, the second one Windows SP3(Installed by me) has VGA not installed, Multimedia audio NOT installed, and there is no SCSI and
RAID Host Controller in device manager.
First: Why did the CPUz, specy didn't detect motherboard name, and only detect the model. IF I need to open the case and shine a light on the motherboard you can usually see both the manufacturers name and the model printed on
the pcb somewhere, then what benfit would be there from hardware detection software?
Second: Yes, my motherboard has integrated video, and integrated audio card
However, this doesn't mean that I don't need to install them since the Vidoe controller is not properly installed (it is a default VGA ) Also, Multimedia audio controller is not functiong at all.
Finally: if And if "SCSI and RAID Host Controller" is still not shown in Device Manager in Windows XP SP3, because these functions are not supported by my motherboard, then why is 'SCSI and RAID Host
Controller' installed/shown in the device manger in Windows XP SP2 on the same PC???

Vold Manager never detects the cd rom and any other removable media

Hi,
I have installed solaris 10(i86pc i386 i86pc) on my PC through Oracle Virtual box but I am stucked in a problem that the vold manager never detects the cd rom and any other removable media devices. I have tried many documented methods but could not get solution to this problem. I also stopped the volume manager (vold) and tried to mount the cd rom manually but still could not mount the cd rom.
I don't know how to configure solaris in such a way that it could detect cd rom and any other removable media.
Any help in this regard will be highly appreciated.
Regards,
Anees

Is it an IDE or SCSI CD-ROM? Can you post back the output of the following command?

What are the latest versions of RAID Admin and RAID Firmware

As of 10/18/06, what are the latest versions of RAID Admin and RAID Firmware?
Currently I have RAID Admin 1.5.
RAID Admin reports my RAID's firmware is version 1.3.2/1.26a.
Am I safe?
Do I have the latest?
Thanks.
XServe G5

You do not have the latest firmware. The latest firmware is version 1.5.
You should upgrade. Make sure you have a current backup and then select "update firmware" from within RAID admin. It will then ask you for the location of the firmware update -- it should be in /Application/Utilities/Xserve RAID Update.

ROM and RAM in mobile platforms

I am very new in j2me so i have a question regarding ROM uses in mobile platforms. I read somewhere in a book or a web site about mobile devices using ROM to store JVM or OS (im not sure which one). I want to know how they use ROM and RAM in their system. Can any one direct me to a website regarding this topic or drop some points on it, I would really appreciate your help.
Thank you

Working photographer needs help with hard drives and raid O decisions

Hi new here and also new to Mac well almost new been 20 years since i had a mac. i have a Mac Pro Book and this led to ordering the MacPro since I am a working photographer i made a complete switch in platforms so i have some questions and such but I did place a order on Friday for a 2.66 4gbs of Ram , 2 500 gb hard drive and a 30 in monitor and of course the ATI 1900 XT card so yes i am waiting like many for that card.
I put initial 4gb of ram since running CS2 will at least take a max of 3gb's in the memory cache . i plan on getting 2gbs more from OWC since that seems to be the only 3rd party ram at the moment that is working correctly from reading some of the threads here. Having 6gbs is a no brainer really given the amount of Raw processing that i do along with PS work plus having e-mail and other apps open at the same time. The ram to me is the easy part although expensive . My biggest issue is what to do with the 2 hard drive slots and Raid O or not but I will start a thread on that. But i will have 6gbs total for now and the bottom line is you can never have enough ram still holds true.
Now on to my diliemma with hard drives. I did have a raid O scsi 10k rapture and and 10 k scratch on my Dell box and I am just not sure what to do here. i ordered the 2 500 gb hard drive and I may just put them on the storage side of things than get 2 WD 150gb 10 k Sata drives. Now i could Raid O them for 300 gb and get a performace boast that way or i could keep them seperate and put everything on 1 150 drive and ue the second for scratch only. What i don't know is what Mac perfers and what works better. Not worried so much about failure of drives, thats just life in the big city stuff and you just have backups. What i more worried about is performance versus a waste . seems to me that Raid O may not even be needed with these new Intel boxes with all the horsepower going on. Now the other think I notice is the WD 150gb 10 k drives are 1.5 and not 3.0 so is it really faster than the 7200 3.0 single hard drives. I read barefeats shoot out and it seems just getting the right drives in 7200 and Raid O them maybe the answer.
Okay i am not the biggest geek on the planet but I do know my stuff but this is a area that i look for more knowledge on this. So if i can get some sound advice in this area. i know there are many photographers out there like me pushing hundreds of images that could use the same advice. Now let's leave the money end out , folks sometimes think more with there wallet than what works best not that I am opposed to saving money but after spending over 7 k already on this system it becomes a moot point. LOL
www.guymancusophoto.com

Ok your question is if you should RAID O the two 150GB Raptors or not.
I think it was wise for you to get a couple of them for a boot drive with "Time Machine" coming in the next version of Mac OS X. The second drive would make a excellent bootable backup and eliminating downtime if a boot drive dies on you one morning.
In fact any boot drive cloning software that is Mac Intel ready now would do you good.
Now Barefeats has run some tests, and I can pretty much back up what they say from my own experience.
Mac OS X and apps can be helped only so much by a faster boot drive, and a single 10,000 RPM Raptor is enough, RAID O a pair is overkill.
If you install everything on the boot Raptor and keep your space hogging files (except iTunes) in new folders on another drive, even a 7,200 RPM 500GB, the two drives combined is faster as there is nearly no wait. Both drives can be accessed at the same time. Keeping the boot drive slim keeps the stylus (arm) moving as little as possible to get all the small reads/writes Mac OS X needs.
I RAID O-ed my boot drives because 74GB was the largest they had at the time, so combining them gave me speed and larger storage. I hardly use the speed, it only comes in handy if by rare chance I duplicate a 20GB folder, then I can do it in half the time of a 7,200 RPM drive.
Some of the drawbacks of a RAID O set, especially as a boot drive is that I have to auto-clone the whole set to a external drive regularly (I actually do a couple). Since the data path is separated with a RAID O, any drive failure results in total data loss.
So if you RAID O those 150GB Raptors, your going to have to clone 300GB to a external drive (or another internal) regularly, like once a week. This will take considerable time and you can't use the machine while the cloning process is going on. Sure auto-cloning software like DeJaVu can be used at night/weekends, but why bother cloning more than you have to for no big speed increase?
However if your messing with huge Photoshop files that spill over your CS2 3GB RAM limit (you need to have a "scratch" thats as fast as RAM), duplicating large files and other heavy duty drive work, then a boot RAID O will come in handy. Just remember your initial performance of 185 MB p/s will drop about 20-25% when those drives are 3/4 filled. Still 140 MB p/s is extremely good and a no worry situation.
What is worrysome is anything below 80MB p/s (I'm talking uncached 4K write speeds under X-Bench) with a new boot drive and then as time elaspes that boot drive gets filled up and loses half or more of it's inital speed. 30 MB p/s is really slow. Beachball H&LL.
http://www.barefeats.com/hard33b.html
Do Erase W/Zero in Disk Utility all new drives before laying data on them. Drives get subjected to shock which causes bad sectors on the drive. Driver software uses your data as a guinea pig to test the sectors (which you might not be able to recover the file). Zeroing does this without your data, rewriting the bad sector map so your writes are much improved, OS is more stable. etc.

Newbie FCP HDV monitoring and RAID questions

Hello forum gods.
First off, I must confess - I am a defector seeking assylum in the the Mac camp. I am a born-and-bred Windows person, and a longtime Avid editor who just made the jump and purchased the Mac-Pro with all the bells and whistles, and FCP Studio. I did this to accompany my JVC ProHD cam and deck.
I have no idea what I am going to do with the time I used to spend scanning for viruses and trojans. I am thinking I may write a novel, or build a house by hand - but that is another topic.
Now that the confession is out of the way - we can move on to the actual questions.
<big breath>
Ok - so I have this new fancy shiny computer, deck, camera, and monitors - one of which is the Sony 23" that is comparable to the Apple 23. I do not have a Kona or Blackmagic card because I was told that I did not need one right away - though I do plan on getting one later. For monitoring, I was going to use the firewire in/out of the JVC deck and convert the signal via the component outs to another HD monitor. This would bring the total monitors on the system to 3 - a 19" for the edit screen, the 23" for the video playback in FCP and the braodacast HD for monitoring the final signal.
Is this workable?
Now for the second question - storage and RAID.
Most of my footage will be either SD or HDV. Eventually I'll be going to XDCam, but that's a bit down the road. I have the internal 250 gigger that came in the Mac, and I purchased additional 500gb SATA II drives that I was going to use to set up a RAID. Should I do this internal or external? Will it work? What else do I need? What is the meaning of life?
Thanks for your replies. My credit card is anxiously awaiting your suggestions
G5 Quad Mac OS X (10.4.8)
G5 Quad Mac OS X (10.4.8)

Some question back atcha:
1) When you say you'll be working in SD, what do you
mean? Typically, SD refers to uncompressed 601, 720 X
486. Or are you referring to DV NTSC?
DV NTSC and/or the myriad formats that the JVC100 can do.
2) Your Profile says you have a Quad G5, but your
post says it's a MacPro. Which is it?
Sorry - Consider that my first public gaffe in the new Mac world. I bought the Mac Pro. Time to change my profile. I bought it last week - it isn't even here yet. Supposed to be delivered today...
3) Are you wanting to see your HDV sequence on a
external video monitor while you're editing? If so,
you'll need the Kona card (or the Blackmagic card,
but I don't do BMD, only Aja, so I don't know about
the Blackmagic offerings.)
I've read about the Cinema Preview function and although I know that this isn't the best idea for monitoring, wouldn't it work? On the JVC deck, it has the firewire output/input and component outs (among others) so in E-to-E mode, couldn't the deck act as my converter for monitoring on the broadcast monitor? If not - I have a line on a Kona-2 with the BOB for about $1400. Deal or no deal?
Now as for your RAID question, you can do either
internal or external. Just don't include the drive
that contains your system folder in the RAID.
I was planning on using the 250 for all my system files and the 2-500 giggers as my edit drives. Sound good?
EDIT: As for the meaning of life, go ask your father.
Gaah... He handed me "The Hitchiker's Guide to the Galaxy" and told me to get to reading....
Thanks for the help. Lord knows I need it.
