Pulling the scsi drive

My G4 has an extra 18g. scsi drive inherited from my G3 and I've been told the drive is going bad. I want to remove it and leave the 120g ide drive. Is it a simple matter of unplugging the scsi drive and taking it out of the machine? I use a scsi external scanner and cd writer so need to continue that connectivity. Once I pull the scsi drive, do I need to do anything with the cables so that the external peripherals still work?
Do I need to press the cuda switch when I remove the drive or is that done only when adding hardware?
Thanks for your help

I put a mechanics stethoscope on both the ide and scsi drives after hearing some unusual noise. The ide was quiet as a mouse. The scsi was screeching like crazy. I suspect the bearing or some other mechanical component was going out and it was suggested to get it out of there before it blew and caused problems with the good drive (ide). The sound the scsi drive was making sounded like a dry bushing that has lost its lubrication so I'm assuming the central bearing is on it's last leg. That particular scsi drive is probably 10 years old. The ide drive is around 4 years old.

SOS!! SOS!! HELP ME!!! The mobo won't load/boot windows from the SCSI Drive!!! HELP!!!

Ok so i got the board and the crucial RAM with a new enermax 450W power supply. I am running the 1MB A64 3400+ CG on this board.
I am using the Seagate cheetah 15.3K SCSI drive with a LSI 21320 SCSI controller
(http://www.lsilogic.com/products/ultra320_host_bus_adapters/lsi21320.html )
I am also running a IDE drive on the primary IDE channel set as slave.
I went to the bios and changed the boot order to use the SCSI HD as the first boot device and proceed to intall windows XP. I pressed F6 to install the SCSI drivers and everything went fine until the reboot after all the files has been copied. I would get an error message saying something like:
"NTLDR cannot find boot drive etc"
I have no idea what to do...i tried everything and i am 100% sure that its not my SCSI HD or SCSI card.
PLZZZZ HELP ME!!!!!!! PLZZZ HELP!!!!!

Found it set your boot order to bootable add in card first in the screen shown here courtesy of HardOCP : http://www.hardocp.com/image.html?image=MTA4MjM1MDg3NWxrOFNyWHJRcTNfMl8yNl9sLmdpZg==
That should do ya.
Also be sure that the LSI controller is configured to use the Seagate drive to boot from. There is usually an option of which channel to boot from in the HBA BIOS.

Choosing the SCSI drive

Hay,
I have narrowed down to purchasing a Mac Pro with the following configuration. Can someone help me chose the right SCSI disk(How many GB's? is ideal for working with 4-5 hours of uncompressed Digibeta footage).
I will have the Internal Hard Disk that comes along with Mac Pro, which is 320 GB. PLus I should go for a SCSI disk of how many GB's? See i am a bit confused here...
I can't at this moment afford a RAID and stuff...
Please help....
I am buying the 3.2Ghz 8 Core Mac Pro, FCP, 4 GB RAM, Blackmagic HD Extreme Decklink...
Can someone tell me what should I ask the dealer for while buying the SCSI disk...I mean I need to buy a SCIS card too right? And how much would let's say 500GB SCSI disk cost me?
Please help urgently

There are some performance tests of SAS vs SATA. I use to be die-hard SCSI on my G4s. Then 10K Raptor. Today, either 10K Raptor which is going EOL or any high density SATA drive.
http://www.barefeats.com
Then look at PCI Express SATA RAID controllers.
There are exceptional 640GB up to 1TB drives.
4GB RAM is almost minimum and mandatory on Mac Pro and actually 8GB or filling all 8 DIMMs gives best performance.
http://www.macsales.com has SATA drives, enclosures and controllers.
http://www.amug.com has lots of reviews of the above.
ATTO is almost the only game in town for SCSI, there are others that handle SAS, but those really add $699 and up for controller before you look into drives themselves.

My 2008 MacBook Pro logic board died and I'm pulling the hard drive out. What Apple computers have room for a 2nd 2 inch hard drive?

The logic board on my 2008 MacBook Pro died. But the hard drive is fine. What Apple computer has room for me to insert my old drive as a 2nd hard drive?

You can add it to any unibody MacBook Pro in the optical drive bay, if you can get along without an optical drive and you aren't worried about voiding the warranty (or if the machine you buy isn't under warranty). You can't add it to a Macbook Air, Mac Mini, or iMac, but you can easily put it into a Mac Pro. And of course with any Mac you can put it into an external enclosure and use it as an external drive.
See my second post in this thread for a couple of enclosure recommendations:

Why do I get a blue screen when I use the NIDAQ driver.

I get IRQL_NOT_LESS_OR_EQUAL.
Address fc792324 has base at fc6f8000 Nidaq32.sys and Address fc7028e3 has base at fc6f8000 Nidaq32.sys.
The system is running on Windows NT 4.0. The application is built using Application Builder and LabView 5.1.1. The NIDAQ 6.9.0 is used.
Please help me.

uffe:
You seek...Yoda...Help you...I...will..
This is a kernel mode problem with your NIDAQ32.SYS driver. I believe
that you can pretty much rule out problems with LV5.1.1 or app
builder. Your problem
You have run into a classic BSOD message. It may not always occur so
it can be really frustrating to diagnose. There may be some
workarounds you can implement at the application level but it still
needs to be fixed at the kernel (O/S) level so you're going to need to
contact NI.
I've had this same problem error message in the past but not with DAQ
cards. As I recall, in one case there was a problem with a spinlock
in the SCSI driver (.sys) file which protected access to the hardware
I was using.
What is a spin lock? A spin lock is a special synchronization
construct used by device driver developers to protect access to
critical sections of their code usually for hardware access. It is
the kernel mode equivalent to a VISA resource lock or a semaphore in
LabVIEW.
For more on spin locks see:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/kmarch/hh/kmarch/k101_97hu.asp
Work-around Possibility #1: Do you have two different parts of your
code trying to access the DAQ card simultaneously? If so, providing
your own VISA resource locks or semaphores at the application level
may cure the problem even if the kernel mode driver is failing to
protect access to the card like it should.
Even if this fixes the problem PLEASE report it to NI so that they can
fix it properly in the .sys file and let other users know that the
workaround I suggested works.
See:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/network/hh/network/103ndisx_7mk2.asp
Work-around Possibility #2: I don't know the details of setting up
your DAQ card so if this question doesn't make any sense don't worry
about it. Are you setting up the card with some empty array, zero
memory size, or empty string value or something? I had this problem
with a reflective memory card driver.
Sometimes this can screw up a driver that isn't checking for this sort
of thing with the result of it trying to reference a null ptr or
something. Again, even if you fix the problem by error checking the
values before you give them to the DAQ driver VI, make sure you tell
NI about it.
This explanation also jibes with what Microsoft has to say on
IRQL_NOT_LESS_OR_EQUAL. See:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/w2kmsgs/6077.asp
3) There may be other explanations for your problem but these are two
that I've run into personally. Try going to www.microsoft.com and
doing a search on IRQL_NOT_LESS_OR_EQUAL if my two possibilities
aren't the cause of your problem.
4) Make sure you have the latest driver from NI for the NIDAQ. NI may
have already fixed your problem in a later version of the NIDAQ
driver.
5) Also I would recommend making sure that you have the latest service
pack (SP6A) installed or that you go ahead and upgrade to Win2000. As
I recall when I had my one of my driver problems it was with an
earlier SP release and upgrading SP's helped.
6) If none of these suggestions help, you need to call NI help line
(800-IEE-E488) and report this to see if they know about it so that
they can give you a work around and see if they can recreate the
problem and then fix it.

Adding 2nd hard drive(IDE 40gig) to B&W G3 w/ 9gig SCSI drive

Recently got a 450 B&W G3 with a 9gig SCSI ultra something drive in it already and i would like to add a 40gig IDE drive as a second. the scsi drive is hooked through a scsi card and is the main drive. i want to just add the second drive for more storage. when i plug up the drive and start up, it does not see the drive. I know i'm missing something little to get this to work, but I don't know alot of the techincal terms and meanings to ask the right questions. any help or if someone can direct me to an older article that might help would be great!!! Thanks!!

Hi, Papa -
Welcome to Apple's Discussions.
Make sure the drive is jumpered correctly. There is a block of exposed pins at the same end of the drive where the power cable and data cable are attached. On those exposed pins will be one or more little plastic-looking things bridging pin pairs - these are the jumpers.
There should be a label affixed to the drive in the vicinity of the jumper pin block; this label depicts the various configurations of where jumpers should be placed for various settings.
For your model Mac, you should use the jumper setting for "Master". Exception - if the drive is a Western Digital brand, it may have a setting named "Single" - if so, you should use that when the drive is the only device on the bus.
If you have not yet initialized (formatted) the drive, do so. Most drives are not usable until they have been prepared for a Mac by initializing the drive; initializing a drive places Mac drivers on it, and structures the platter for use by the OS.
You can use OSX's Disk Utility to initialize the drive. There should be sufficient info in OSX's Help section to use Disk Utility to do that. Some items of note -
• If you want that drive to be accessible when the machine is booted to OS 9 at some time, be sure to select the option to install OS 9 drivers.
• Select "Mac OS Extended" as the format for the drive.

Quicksilver scsi drive size limit ?

Hello all.
The original 37gig SCSI drive on my Quicksilver (NOT mirror door) is beginning to sing a sad song so I am looking into replacement.
I know there is a 128gig size limit for ATA drives in this model but is there any size limit for internal SCSI ????
I have already added a 120gig ATA with my original 80gig ATA so I think I'm pretty well maxed out (heat and power wise) on internal ATA drives.
Due to the cost of SCSI drives I'm thinking what I may do is buy an external LARGE firewire dive, transfer the contents of my internal SCSI drive to that firewire drive and then just use the SCSI drive as a dedicated "video capture" drive until it finally dies.
So, besides the original question about SCSI drive size limits does anyone have anythoughts on going external firewire vs. additional internal drives?
Thanks.

933mhz PowerPC G4 Mac OS X (10.2.x)

Hello! If speed is an issue get a sata Raptor drive (most 36 or 80 gigs). The access time is as fast as a 10,000 rpm scsi drive. Just add a sata card to use the sata drive. Tom

Which drive is the boot drive?

I installed a 2nd hard drive in my G4 dual 1ghz sometime around 2001. I'm now on a G5 and would like to pull the 2nd drive from the G4 and put it in a firewire enclosure to use with the G5. How can I tell which drive is the boot drive and which is the secondary drive? I kind of remember that the 2nd drive went in the lower bay but I'm not 100% sure. Any other caveats to pulling out this drive? Thanks in advance.
Power Mac dual 1ghz

The system profiler should tell you the serial number of the hard drive, or type of hard drive when you select it in the IDE bus. Compare that with the label on the drive itself.
Both bays can have boot drives, though typically master jumper drives are better able to boot than slaves on certain operating systems.
You can tell the existing boot drive, because it is the first drive that appears in the upper right hand corner of the desktop if you view and arrange the desktop by kind.
If you just want to transfer data over from a G4 to a G5, you may want to use Target Disk Mode:
http://docs.info.apple.com/article.html?artnum=58583
Note, if the G4 is the kind that can boot into Mac OS 9, set it as the Target machine. In addition, if it is running 10.2.2 or earlier it should be the target machine, because 10.2.2 and earlier don't understand the Journaled operating system which may be installed on your G5.

Ultra 10 OBP can't see SCSI drives

I'm trying to get my Ultra 10 to boot off a SCSI drive. I've tried several controllers (SYM21002, SYM21003, and another 53c896 card) and several drives, but probe-scsi-all returns nothing. If I boot off an install CD (the CD drive is still IDE), I can see the drives and install an OS on them, but when I reboot it still can't see the drives at the ok prompt. I've tried OBP 3.31 and 3.29 with the same results in both. Any idea how I can get it to boot off a SCSI drive? Or, failing that, is it possible to boot a bootloader on an IDE drive, which then boots off the SCSI drive?

you say you can install with scsi drives, but on restart it won't boot? what is the U10 looking for? did you try boot disk ? the U10 may be looking to boot off the network or somewhere off..
I don't recognize the chip numbers... are they supported by Sun? I have only used Sun-branded scsi cards--- 375-0005 comes to mind...

Internal scsi drives on mac pro?

I have just received my Mac Pro, which will soon be put into use as the center of a commercial audio recording facility. I was under the impression that the SCSI drives I had been using in my aging MDD dual 1 GHZ would be port-able to the new box. But, after snooping around a little bit on the boards here, and looking into the machine itself, this appears not to be possible.
Is it true that ONLY SATA drives are compatible as internal drives in the new Macs?
If so, then I need to sort out my new drive configuration for the studio machine. For better or worse, my studio uses ProTools, which does not support RAID of any sort. So I'm left looking at sharing the internal SATA bus with the system drive, going with an external FW800 drive, or investing in an external SCSI drive (ugh).
Any thoughts would be welcome.
Thanks,
Nick
mp 8-core 3ghz Mac OS X (10.4.9) 8gb RAM

following up on this thread -
I purchased the external chassis recommended above and have compared transfer rates with the somewhat unscientific copy time test, from the desktop of the apple SATA boot drive to and between various other drives. It appears that the internal SATA 7200RPM drive I bought from OWC is outperforming the external (10000RPM) SCSI drives I have mounted in the enclosure. This seems odd to me. I'm not sure if the bus speed is being ratcheted down to accommodate the cabling (SCSI 3) or what. I appear to be getting roughly one third of the 160MB/S limit on the Ultra160 drive (the buffer size is 8MB on this drive as opposed to 16MB on the 7200 drive).
Theoretically, the bus throughput is higher on the SATA bus, but I thought that would be outweighed by the drive performance - that appears not to be true. It also appears that the SATA drive is FASTER on the duplication process than the SCSI drive, which leads me to believe that the rotation speed is being trumped by something else - buffer size perhaps?
Any thoughts would be welcome. Here are the results of my testing.
Copying 1.27GB .zip archive:
desktop to 2nd internal SATA drive: 19 seconds (68MB/S or .53Gb/S)
desktop to external SCSI drive: 25 seconds (52MB/S)
2nd internal SATA to desktop: 19 seconds (68MB/S)
Duplicating 1.27GB .zip archive on the same drive:
internal SATA: 50 seconds
external SCSI drive #2: 58 seconds

Why can't I boot from an external scsi drive?

In a previous post, I mentioned that my hard drive died. While trying to find ways to work around it, I dug out an old 4 GB SCSI drive I used to use with my old Mac, and hooked it up. When I booted from the OS 10.3 install disk, I was aboe to install the OS on the external drive, and choose it as the startup drive before rebooting. When I rebooted, however, the Mac could not see the SCSI drive as a startup drive. I tried it several times, changed the SCSI ID, erased the drive and reloaded the OS, repaired the directory with Disk Warrior, all with the same results.
What am I doing wrong?
Dave

What model SCSI card do you have installed? Some cards are driver-based, like the Adaptec 2906. Its driver is loaded from the boot drive, as the extensions are displayed across the screen during the startup process. As such, drives connected to that type of card can't be designated as the boot device. A newer SCSI card that's firmware-based, like the Adaptec 2930, can be used for booting the computer. If you have a card that's firmware-based, then you may need to update the firmware with a newer (Mac OS X) compatible version.

I just tried to copy a folder to a pen drive from my mac. It transferred fine. I then ejected the pen drive then pulled it out. When I pulled it out it said it had not ejected correctly despite me just Doing this. The folder is now missing from both! Help

I just copied a folder from my desktop to my pen drive. It transferred fine. I then ejected the pen drive then pulled it out. On doing so it said it had not been ejected properly!!!!! The folder is now missing from my computer and the pen drive. Pulling my hair out please help!

When youi say Eject, the RAM copy of the Directory is written back to the drive. On a pen drive, this can take several seconds.
If you get too excited and don't wait those few seconds, the directory write will be incomplete, and the drive will lose its integrity or lose files or both.

Can I connect an external DLT Tape drive to the SCSI connector on an E450

Hi... totally new to SPARC. I have inherited an E450. It appears to have the 8 bay option. I have 6 scsi disk drives installed in slots 0 through 5. Internally, there is one ultra scsi controller in slot 2 and two internal cables running from the top of the card, one for each channel. I do have an extra ultra pci scsi card, but when I plugged it into a pci slot, the system would not boot. Bottom line, can I connect an external DLT drive to either Channel A or Channel B at the rear of the Unit and not intefere with other SCSI devices (i.e. the disk drives). Currently, the DLT is set to SCSI ID 8. If this isn't recommended, how do I install the secondary ultra scsi card and have the system recognize it ? Note that the Hard drives have been wiped and I WILL be loading Solaris 10, but have not yet. I wanted to make sure all of the hardware worked first. The second PCI Scsi controller I have is an Adaptec 39160, and I'm assumming it will work IF needed. I'd prefer not to use it if necessary.... ANY HELP is sincerely appreciated ! Thanks, Randy

I suggest you leave the current internal connections just as they are.
You never know when you'll need to add more disks.
That Adaptec card is for PC's.
It won't work in a Sun SPARC-based system.
What sort of SCSI interface is required for that tape device?
Single-Ended? High Voltage Differential? Low Voltage Differential?
You need a card that matches that interface type if you hope it to "drive" the tape.
One quick way to tell, is to examine the chassis of the tape peripheral
and find the small icon that should be at the port for the SCSI cable.
For example, Sun's 375-0005 card is Single-ended and is what you already have inside your E450.
Sun's 375-0006 is a HVD card and would be correct for A1000 and D1000 arrays or L7 or L25 tape libraries.
Sun's 375-3057 card is LVD and would be appropriate for Sun's D2 array.
The manual for that 375-3057 card happens to have pictures of the SCSI icons I just mentioned.
See page 35 in that manual.
http://192.18.109.11/816-2156-11/816-2156-11.pdf
Once you confirm what's needed by the tape peripheral, we may be able to suggest how to connect it properly.

My hard drive failed. My applications were on the drive including Excel, Word, and Powerpoint. Apple told me I could pull everything from the failed drive. I tried that but the drive is bad so I can't get to anything. Do you think Apple will reinstall?

Thank you!

Thank you everyone. I apologize to confusing all but I am up to date and running OS X 10.8.2. It's possible I purchased the key for Office but I don't think so although it was 3-4 years ago. I guess I will stop in the Apple Store and just ask. I may just buy the new bundle anyway to get the most updated.
I have read there are issues with the MS Office bundle running on our latest OS, is that true?
Thank you all!!! You've been great!
