PowerMac G4 "Mirrored Drive Doors" 2x1GHz Hard Drive Upgrade

I have a PowerMac G4 "Mirrored Drive Doors" 2x1GHz with one 75 GB PATA hard drive.
I want to install two 500 GB PATA drives.
1) How is this done while transferring all the data from the 75 GB drive to the new drives?
2) Is a master/slave configuration the only option for two PATA drives?
Regards,
David

I prefer not to cut pin 28 wire so I’ll go with the master/slave (device 0/device1) configuration.
I do not know to what you refer. I have two 300 gig drives in my MDD, connected without modification to the cable (to which the original 80 gig was connected). The drive jumpers are set as cable select. Repeat - no modification of the cable was ever done. In fact, but this is from memory, I believe I could not boot from drives that were jumpered as "master" / "slave".
Can anyone confirm the number of PATA drives that will fit in a MDD?
As shipped, the MDD is wired for up to four hard drives. There are two cables and each will let you connect two drives. One of the buses is slower than the other - the faster one is where the original drive is located.
Are the bays under the CD/DVD drive set-up for SCSI drives?
No. You need a scsi card to use scsi drives.

PowerMac G4 (Mirror door drive) shuts down automatically when starting up.

I use a PowerMac G4 (Mirror door drive) 1.25 Ghz processor with1.25 GB ram, 80GB HDD. OS 10.2.7
Recently I could not start the machine as it automaticallyshuts down during starting when the log in dialog box appears. It also creates excessivesounds (hopefully from the processor fan) during starting up.
What is the possible cause for it? Upgrading the OS (10.5.8) could solve it? Or suggestions from exparts like you? Plz Help.

Thanks BDAqua. Sorry, no actionsworked. I think, the possible cause might be, the processor heats up more andthe fan start rotate more to cool down the processors and it makes the sound.But processor becomes hotter and the CPU automatically shuts down.
Apple service center in my townseparated, cleaned and reinstalled the processor & motherboard from thecase but NO IMPROVEMENT. They are trying to suggest (with confusion) changingthe processor. Do the diagnosis going right path? They do not have any G4 1.25 GHzprocessor, where will I get it? Anysuggestions from the experts of this forum?

Upgrading OS 10.2.8 to 10.4 in a Mirrored Drive Door PowerMac G4

Hello,
I'm trying to upgrade the OS from 10.28. to 1.4 in my Mirrored Drive Door Power Mac G4. All the system requirements are met, the firmware is current, and there should be no problem, but I get a message saying "The system can't be installed in this machine" ... any idea of what may be going on?
I upgraded the system in a external drive without any problem from a PoweBook G4, so the installer seems to be OK ...
Thanks!
B

If you have a "full retail" 10.4.0 disc (black with Silver-White 'X') it should install in a Mirrored Drive Doors G4 without issue. A 10.4.7 disc may not install on G3 systems. The Mirrored Drive Doors G4 has certain unique Hardware not found in earlier Macs such as the PowerBook G4.
A gray or orange disc for a different Mac will not contain all you need, and will probably not install. A G5 disc contains special version for the G5 only.
An "Upgrade" disc requires the previous system installed and mostly functional, and just adds the changes.

G4 PowerMac mirrored drives won't boot after software update

This IS NOT about my PB but a PowerMac tower, G4, mirrored drive....running 10.5 (I think).
After some month of neglect, did software update yesterday.... 7 programs including a security update, iTurnes, QT, and I'm not sure what else.
Now it won't boot.
I have a Disk Warrior CD, but I can't get the SuperDrive door open to try to boot from it.
Help GREATLY appreciated.
Thanks,
TD

Updating
Certain steps appear to minimize the risk of an update producing problems.
Number one is to make sure you have a bootable clone backup of your computer in case you do need to back out of it again. This is the only guaranteed way of not having to worry about the results of an update.
Some like to boot from their installer discs or an external backup and verify (and if necessary repair) their internal drives as well as drive permissions. This is done with Disk Utility. You can verify a drive while booted from the same drive but sometimes this produces spurious errors. Repairing a drive (if necessary) has to be done while booted from another disk. Permissions repair can, and is probably best, done when booted from your internal drive.

You can also go to the step of booting into safe mode to do the install.

[Safe Boot takes longer than normal startup|http://docs.info.apple.com/article.html?artnum=107394]
I like to download the update onto my computer and install it from there rather than let Software Update do it. I know a few people who had problems with doing the update via software updater found a manual install to work.
Repair permissions again afterward.
It helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
The more cautious even like to unplug third party peripherals (see [comment by BDaqua|http://discussions.apple.com/message.jspa?messageID=9040746#9040746]).
Almost all of the above steps (except backup) have been questioned as to necessity because probably many people have done successful updates without doing them. I say they can't hurt, they can very likely do good (especially if your computer isn't regularly maintained), so why not do them to be safe.

Fit and usage problems with second DVD burner on Mirror Drive Door

I got a Mirror Drive Door Dual 1.25 GHz (Firewire 400 only) to replace my dead Digital Audio model. It has been working fine for the past week, so today I was trying to transplant all my compatible upgrades over from the Digital Audio, but I am having problems with using 2 DVD burners.
I left the original Apple Super Drive in the top optical bay and put my LaCie Lightscribe burner in the bottom bay.
My first problem is that the opening in the lower bezel is too small from side-to-side for the LaCie tray to come out. It hits the bezel and goes back in. It looks like it is off by about 1-1.5mm on each side. I don't know if the drives will fit if I reverse their positions or not.
Secondly, I don't think the jumpers are set correctly, and I am not 100% sure how to set them. I am guessing that they both need to be "Cable Select" like the hard disks in this model? I think I would prefer that the Apple drive stays the main drive. Right now, when I press the eject button on the keyboard, all I get is an endless cycle of the lower drive trying to eject its tray. I'm not finding the procedure for ejecting the the top Apple drive. Is there a key combination to select the upper drive? So far there is only Tiger 10.4.11 on this computer, though I will be installing Leopard shortly.

I am guessing that they both need to be "Cable Select" like the hard disks in this model?
Depends on the IDE cable, Master & Slave may be a better option.
Might try this...
On your main hard drive, dig down into System > Library > CoreServices > Menu Extras. Inside that window, double-click on the icon called Eject.menu.

If two drives are properly recognized it'll allow you to choose which one.

How do I get my Mirror Drive Door G4 to start up in 9.2.2? Retail disk doesn't work.

So my boss came in with a Mirror Drive Door G4 running 10.3.x and told me to get OS9 running on it. "Piece of cake," I told him.
Just as the curmudgeon at the used PC store assured me, my retail copy of OS9 will NOT install onto it. One MUST use the restore disks specific to this machine, he said. Seemed counter-intuitive, that a retail copy of OS9 somebody had paid for would not install 9 onto a mac that can run 9. But he was right. So I bought CDR copies of the restore disks that came with the MDD. Whether these pertain to the exact MDD I'm using is another question.
After much headache, I was able to get run the OS9 system restore package cuncluded by a window that reported success. The startup disk preference window in OSX could see the 9.2.2 system folder. I selected it and restarted. It tried, but then stopped, made another unreasonably loud JONG noise and presented me with a flashing "no OS folder" icon. I was only able to start back up using a 10.3 install disk to select the 10.3 system folder on the HD.
This machine is able to start up in OS9 if I install an old HD from my ancient snow iMac into it. What's that about? It can start up using that non-MDD-specific system folder but not the one specific to this machine?
The drive I'm having trouble starting up from was erased with OS9 drivers installed before 10.3 was installed, followed by 9.2.2 from the restore disks.
What am I doing wrong?
Thanks folks.

Yes, there is.
OS 9 can not boot when installed on a volume larger than 200GB.
The good news is that this is a volume size limitation, not a drive size limitation. This means that you can partition a drive larger than 200GB such that the volume used for OS 9 booting is not larger than 200GB; to allow for formatting wiggle room, using a max volume size of about 190GB is safer.
When reforatting the drive, remember to make sure tha OS 9 drivers are installed.

Help Regarding Hard Drive Upgrade (Method, Model, Raid)

Hello,
I have a W520 with two 500GB drives in stripped RAID configuration. One of the two drives has been making a crunching noise, followed by a beep.
I called tech support, and it was not very helpful. I have the next business day at your door warranty, and they are sending me a new hard drive to install myself, in about 5 business days (not sure how this is, given the warranty I've had, and never used until now...).
In any event, my drives are nearly full, and if I'm going to go through the trouble of changing one anyway, I'd rather just replace them both with larger drives.
My goal is to have the largest drives possible, and do the upgrade as easily as possible. I don't really care if RAID is in effect or not, as I don't feel I've noticed any real performence increase anyway.
I have in the past upgraded Thinkpad drives to larger drives, but these were in single drive systems. I'm "handy" with computers, in a do it yourself kind of way, but really just an amateur with this stuff. I'm concered about the dual drive aspect and the RAID aspect with this one. The tech support guy said they have no information to share about how to do a drive upgrade, that they just ship the drive (which I'm probably not going to use now anyway).
So these are my questions, and thanks to anyone who takes the time to share any advice...
1) What is the best, largest compatible replacement drives to get? I don't care about speed of the drive as much as size.
2) What is the best way to copy off/clone/mirror the existing content on my existing drives? I bought a device off Amazon to do this a few times - one of the times, the device literally started smoking... I'm not sure where I put the last one I used (where you connect to the new, bare drive).
3) Can I just disable RAID in the bios once I've copied the old drives to the new drives (or to an external backp-up drive)? If it is easier to just disable it and have two separate drives on my system, I'm fine with that.
Again, thanks for any help with this.
Jason

Hi, Denny.
...and when I took it apart and proceeded to
load in the new hard drive I noticed that the new one
did not have connector pins to hook up to the flex
cable on the hard drive.
So you removed the old drive, you detached the short flex cable from it, and now you find nothing on the new drive to connect the cable to? Am I understanding correctly?
If so, is it possible that the connector on the new drive is covered with some sort of temporary shield to protect it during packing, shipping and handling? If it is, the shield should come off if you pull it in the same direction you pulled the flex cable to detach it from your old drive.
I'm tempted to say you are surely missing something. For Hitachi to have shipped a drive that has no cable connector seems about as likely as for Toyota to have shipped a car with no tires installed, but I suppose anything is (barely) possible.

How to reinstall bootable system 9 in a PowerPC G4/1.25 DP (Mirrored Drive)

Hi all, I have two machines bootable with OSX and OS9
PowerPC G4/1.25 DP (Mirrored Drive Doors) dual 1.25 GHz PowerPC 7455 (G4)
and
iBook G3/900 900 MHz PowerPC 750fx (G3)
I have some MACOS9 software which just doesn't work in classic mode with any OSX
I got the system disks stolen while travelling. Any Panther or Tiger will install easily in the OSXC partitions I have, the machines, there is some kind of soft lock preventing the regular OS9 system Software disks to install in the OS9 parts of the my drives- So I am now unable to reinstal and booth from system 9.
I tried it all partioning the HD, leaving it as is .... but nothing happens. As soon as I insert any System 9 install disk the computer rejects it telling me is not for that machine, and booting from CD is not happening either with a similar message.
I am unable to locate reploacement disks anywhere and Apple here in Taiwan is silent on this matter, what to do?
Thanks

Hi, Dante!
I have no idea what your unpublished comment was concerning ethics, support, or whatever, but this is a user forum which largely consists of people from all around the world who are citizens of many countries. As such, it's really not a soap box for attacking the ethics or morality of fellow members, their countries, their backgrounds, or their beliefs. The folks who responded to your inquiry did so both voluntarily and for your benefit, while trying to consider your best interests. Responding by inferring that the people who earnestly offered to assist you lack ethics in their standard view of things indeed strikes me as an undeserved insult of them.
That being said, perhaps one of the following approaches might work better for you, while sparing you from having to deal with any allegedly unethical peoples of one nation or another:
You might just file a police report and wait for your local police to find and return the missing discs.
Alternately, you might consider publishing a public appeal to the morality of person that took them, particularly if they were stolen in an "ethical" country during your travels.
You could also file a claim with your insurance company and use your reimbursement to buy replacement discs or maybe even flags to burn.

MIRROR DRIVES

We are running SBS 2008R2 on a HP Proliant ML150 G6. We had 2 Mirrored WD 500 GB Hard drives, and 1 drive failed. We are running very low on HD space. I ask hp support if I could add a 1TB hd and mirrow it to the known good 500gb hd they said yes.
It did not work properly. Here are the steps I did.
1 - Removed the mirror and volume
2- Installed the new drive
3- Went to Computer maintenance storage
4- Right click on the 500gb drive and selected add mirror. It gave me error that the sectors are not the same.
5- I right click on the 500gb drive and selected new mirror. Selected the new 1TB drive and it formatted the drive to 500gb leaving
500 gb not formated. It created the mirror and says the 500gb is not fault tolerance, but the 1TB drive is. I though it would mirror the OS too, so that I could boot from either drive. When I look at the storage it has nothing in it it say its 100% free.
What am I doing wrong, Please Help and Please detail answer. I am not a tech. Due to cut backs I inherited this job. Please Help.
We are running on the 500gb drive now but with only 5 gb free space.
Thank you very much poppy

Please contact HP support for quesiotns on hw to work with HP RAID. This is a scripting forum andnot the correct place to ask this quesiton.
You cannot mirror 1Tb to 500Gb because the volume or drive topology must match. You can create a 500Gb volume ont he drive and mirror that on some RAID controllers. Each has specific vendor issues so contact HP.
(the default sector size for a full 1Tb volume is larger that for a 500Gb volume. You must prep the drive to do this. HP support will step you through it.)

How can I browse T.M. backups made BEFORE internal hard drive upgrade?

Hi, all. I have googled and googled with no info on my particular situation. Maybe one of you can help. Here's hoping...
I have a MacBook Pro and use Time Machine to back up to a Firewire hard drive. I do not back up my System and Applications, just files. Consequently, when I recently upgraded my internal hard drive I restored all my data and settings from the original internal hard drive (not the Time Machine).
From there Time Machine began making NEW backups of the NEW hard drive, no problem, but I cannot browse the backups of the previous internal hard drive. Is there any way I can get Time Machine to recognize all of these backups as existing from the same machine and let me browse back beyond the internal hard drive upgrade?
Any help is greatly appreciated!

I think you have to browse them separately, but you should be able to do so by right-clicking (control+click) on the Time Machine icon in the dock or by holding the option key when clicking the icon in the menu bar.
Choose "Browse other Time Machine Disks" and you should see the old series of backups.

Retrieving data from a mirrored drive

Hello,
Can anyone advise how to retrieve/access the data on a mirrored drive? Both the primary drive and the mirrored drive do not load onto the desktop, and in Disk Utility only the mirrored drive shows up in the list of drives, unhighlighted. The only option given in Disk Utility is to delete drive, or "other options", which does not really offer any options.
The drives are definitely mirrored. It is a 10 terabyte system, with 5 separate drives mirroring the other 5. The files are not split between the drives. The primary drive not mounting is the one with all the media on it. The media is totally off-line in Final Cut Pro, so the mirrored drive is not automatically backing up the data/media.
How do I access that media on the mirrored drive?
Thanks in advance for any help.

Without actually knowing what the actual arrays are I can't tell you. I'm still not clear whether there are two striped arrays mirroring one another or five separate drives in each enclosure with one drive mirrored to another in the other enclosure or if you have ten drives with ever other pair in a mirrored RAID or something altogether different. I don't even know if these RAIS (whatever they are) were set up using Disk Utility or some other hardware or software.
Let's assume for the sake of argument that there are two boxes - A and B - each with five drives. Box A consists of drives A1, A2, A3, A4, and A5 while Box B has drives B1, B2, B3, B4, and B5. I can conceive of some basic configurations:
1. Drives A1-A5 are configured as a striped RAID and drives B1-B5 as an identical striped RAID. Box A and Box B are configured in a mirrored RAID.
2. Drives A1 and B1, A2 and B2, A3 and B3, A4 and B4, and A5 and B5 are each configured as mirrored RAIS.
3. A1 and A2 are mirrored, A3 and A4 are mirrored, A5 and B1 are mirrored, B2 and B3 and B4 and B5 are each mirrored.
With the first configuration your data will be lost if one drive goes bad in one of the striped arrays, but may be intact on the mirrored array. The RAID software will need to be used to first "break" the mirrored RAID but leave the striped arrays alone.
In the second configuration use the RAID software to "break" the mirrored RAID with the bad drive. The data should be intact on the other drive used in the mirrored array.
In the third setup you would do the same as in the second, but just have different drives involved.

Very slow reads from Mirrored drives

Hi all -
I'm running a Tiger G5 Xserve with mirrored 80Gig SATA drives as the primary HD, and a standalone 250Gig SATA drive in the third bay. At the end of each workday, SuperDuper does a smart update from the mirrored drive to the standalone drive as a backup, and it takes about 40 minutes to run through 40Gigs of data.
I also backup via SuperDuper directly from the mirrored drive to an external 2.5" 80Gig firewire drive once a day for offsite backup, and that takes 40 minutes.
That means I'm getting nearly identical performance to an onboard SATA 3.5" and an external Firewire 400 2.5" - strongly suggesting that it's something in the RAID mirror, rather than in the interface or SATA channel of the receiving drive.
Last week, for some reason, I selected the standalone drive as the source for the backup, and it took 8 minutes. After a bit testing, it seems clear that doing the same backup takes roughly 5x longer when the source is the mirrored drive. The server load is quite light at backup time - under 20% before the backup, under 50% during the backup, even though smart update has a LOT of files to sift.
My understanding is that mirrors are often slower to write than other configurations, as they have to sync, but this is almost entirely a reading transaction, and I've never seen anything about mirrors being so slow to read relative to a standalone.
It this normal? an artifact of the software RAID? Something misconfigured?
It's not a huge problem for me, but since I run this procedure twice a day, it'd sure be nice to have it be one that I come back to in 10 minutes, instead of an hour.
Thanks in advance!

Hi Dean Larue-
This may all be logical, but I would double-check the SuperDuper settings just to make sure that you aren't doing different backup types.
The two 80GB are doing a lot of other stuff whilst you are backing them up and the 250GB just had to read and push files.
I would also imagine that the 2X80GB drives are fuller percentage-wise than the 250GB drive as this too would impact performance.
As it has no files to compare while backing up, SuperDuper is often faster doing the initial backup. Comparing the files on the source drive to the many files on the backup drive takes time.

Hard Drive upgrade

I'm considering a hard drive upgrade but i dont know crap about them. I went over to newegg because i heard it was a good site and found this one......
"Western Digital Scorpio Blue WD5000LPVT 500GB 5400 RPM 8MB Cache 2.5" SATA 3.0Gb/s Internal Notebook Hard Drive -Bare Drive"
The only problem is, I dont know wheter it is compatible with my Early 2009 13 inch macbook pro..... Should I go with this one or are there better ones out there? I'm not really worried about price. I was aiming to get a 500gb. Thanks.

It is compatilbe if it's a 2.5" notebook SATA II 3.0 Gb/s model. Take Csound1's advice. If you buy a WD drive or any other makers' drives do not purchase any "green" drives as they don't work well in Macs.
If you want better performance get a drive rated for 7200 RPM with as large a cache as possible (typically 16 MBs.) Other makers to consider include Hitachi, Seagate, and SamSung.
If you want faster speed consider the Seagate XT500 hybrid. Or visit OWC and look into their DataDoubler that enables you to replace the optical drive with an SSD (or another HDD.)

Hard Drive Upgrade - Incorrect Capacity Shown In Disk Utility After Installation

I have an older model Macbook Version 2.1 that had an 80GB hard drive installed. I have just installed a Western Digital Scorpio Black 500GB internal hard drive upgrade and successfully cloned my data over using Carbon Copy Cloner. The problem I have encountered is that only 98.1GB of capacity is shown in Disk Utility for the new hard drive. After starting the computer using my bootable copy via an external USB drive, I formatted the newly installed 500GB drive with the appropriate Apple formatting (e.g. GUID and Mac OS Extended Journaled) but it only shows 98.1GB of space available on the new drive. I was able to successfully clone the information from my bootable back-up of the old drive to the new drive but I just don't have the full 500GB capacity available to me.
What should I do? Is this a problem with the new hard drive or is there something I need to change on my Macbook to "see" the whole capacity of my new drive?
Thanks for your advice,
Dave

Hi Andrew,
When I formatted the new drive did it with 1 partition and it displays a TOTAL of 98.1GB free space (both in Disk Utility and About This Drive). As far as I can tell, the Macbook is treating the new WD drive as if it is only a 98.1GB drive rather than the 500GB drive that it is.
Thoughts?
Dave

How do I reinstall my operating system after hard drive upgrade on MacBook pro? I have Snow Leopard install disc

How do I reinstall my operating system (Snow Leopard) after a hard drive upgrade. I did a Time Machine backup before the new hard drive was installed. I put in the Snow Leopard install disc and don't get the icon I'm supposed to double click to install Snow Leopard and then the backup.
HELP PLEASE!!

Is the new HHD in the MBP?
Is the new HDD formatted Mac OS Extended (Journaled)?
Where is the old HDD? In an enclosure? What is on the old HDD, your user data? Is the Snow Leopard System on it?
Do you have a separate Time Machine Disk with your user data?
Answers to these questions should give an exact status of your situation so that one can proceed in the right direction.
Ciao.
