Unmounted second hard drive in OS X Tiger

Hello there:
Suddenly the second hard drive in one of my computers, a G4, it's no longer available. This is not the main HD, just a back up drive. Any ideas?
Best wishes, as always,
Federico (aka euskir)

OK, I'll assume you've rebooted already..
As a test, not that we'll actually try to recover anything yet, but there are a few Apps that can adddress a Drive that isn't seen in DU, so try some of these to see what happens.

This one would require another HD with plenty of space to recover to.
You should use another Boot Disk or other Mac with this one in Target mode to do the recovery.
They have a free demo to see what it could recover.

They have a trial version, so I guess you can see if your data can be recovered...

FileSalvage is an extremely powerful Macintosh application for exploring and recovering deleted files from a drive or volume. FileSalvage is designed to restore files that have:
    * been accidentally deleted.
    * become unreadable due to media faults.
    * been stored on a drive before it was re-initialized/formatted.

Adding and configuring a second hard drive in a Power Mac G4

I am using a Power Mac G4 with the original 20GB hard drive and running OS 9.2.2.
I would like to upgrade to 10.4 (Tiger) installing it on a 80 GB Seagate Ultra/ATA 100 which I need to install as a second hard drive.
This is where my problem arises. From what I have read I cannot install OS 10 on a drive configured as SLAVE. On top of this Apple article ID 106728 has a note not to “change your Apple –installed disc drive to ATA ID-1 (slave) when adding other ATA devices.”
Is this article correct or am I misunderstanding it? I was hoping I could just install the new drive on top of the original and switch the configurations of the drives making my original drive the SLAVE and the new drive MASTER and just install OS X on the new 80GB drive.
Or can I put the new drive in the position of my original drive configure it as MASTER and put my original 20GB drive above it and configure it as slave?
I am hoping someone can let me know if these configurations will work.
Another question is: If I switch the position of my original drive will I lose access to the data on it?
I would like to keep the OS systems on separate drives because I need to continue to run my old software and Heidelberg scanner (SCSI, running on LinoColor Elite 5.1 for which updated drivers are not available). This will not be possible in classic. I want OS X on the larger drive as I will be loading updated software eventually and it will become my main OS system.

Hi, Thelisa -
Welcome to Apple's Discussions.
Is this article correct or am I misunderstanding it?
Yes, to both - the article is correct, and yes, you seem to be misunderstanding it.
In the context of the article, "Disc drive" does not mean a hard drive. Earlier in the article it states -
Solution
"Disc drive" refers to CD, CD-R, CD-RW, DVD, DVD-RAM, DVD-R, Combo drives, SuperDrives.
The reason is that on most (if not all) G4s, an optical drive must be jumpered as Master in order for it to be a bootable drive. So, if an optical drive has been jumpered as Slave, it can not then be used to boot from the OSX Install disk.
You will need to place the drive to be jumpered as Slave in the top position of the bracket (the drive sled), and the one jumpered as Master in the bottom position of the sled.
The reason for this is the location of the connectors on the IDE ribbon cable (the data cable) - the one jumpered as Master needs to be attached to the end connector of the cable, and the one jumpered as Slave to the middle connector of the cable.
Because of the physical limits of the cable itself, the one jumpered as Slave must be on top, else the connectors won't reach to the proper drive.
Which drive is jumpered as which is your choice, but the one jumpered as Slave must be on top.
If I switch the position of my original drive will I lose access to the data on it?
No.
The designation of Master or Slave is, for the most part, simply to allow the Mac to have a unique physical address for each drive, so it can tell one from the other (this is separate from the pathname addressing that the OS uses). Re-jumpering a drive nor changing its physical location will not affect its contents nor their usability.
One result that may be important sometime is when the machine in question is set up as the Target machine in a firewire Target Disk Mode arrangement - only the drive jumpered as Master will be visible on the Host machine.

Using the second hard drive in my G5

I bought my Mac about 14 months ago with twin 250GB hard drives fitted. I wanted to use the second hard drive to store my CD collection through itunes.
I have tried to install itunes on the second hard drive but the software installer says it has to go on the startup volume. I have also tried copying my itunes folder and pasting it to the second hard drive as a backup but it won't allow this either. It says that the drive cannot be modified.
How do I use the second hard drive as intended? I upgraded to Tiger so do I need to install that on the second hard drive?
Thank you.

Hi Mike;
I have a 250 GB and a 160 GB hard drive in my Quad. A long time ago when I had much smaller drives, I did move Users to another disk because I was running out of space on my system drive. One of the problems I ran into with this was when my second drive with Users on it didn't start quickly enough for OS X. OS X created a new Users for me with nothing in it. It was a royal pain getting my system pointed back to the Users on the second drive.
What I do now is leave Users where OS X installs. I now move just my project files, music, photos and web pages. I find that this is largest part of Users. It is also the part of Users that I am the most concerned about. With all of my project files on another drive, the system is able to access data from both drives very quickly. It also makes backup simpler.

Second Hard Drive & Insufficient Privileges

Hey everybody...
I installed a second hard drive in my lower drive bay and am now trying to erase it (in order to format it for use). It shows up in Disk Utility, but when I try to erase it (with Mac OS Extended (Journaled), and after I enter my admin password, I get the following error message:
Disk erase failed with the error: insufficient privileges.
I have verified permissions on my first drive, which I am booted up on. I've also tried booting up from the Tiger DVD and running Disk Utility from there, and I get the same error.
The new drive is a Maxtor 250gb DiamondMax, and I can find no instance online of anyone having problems with this drive on a Mac.
Otherwise, here are the system basics:
PowerMac G5
Dual 2ghz
2GB RAM
Thanks for any help you might have!
PowerMac G5 Mac OS X (10.4.8)

Thanks yet again.
Interesting stuff, but since the new Maxtor is not yet recognized as a volume (outside of Disk Utility), those terminal commands didn't work. It kept returning the error that there was no such volume. I tried every different spelling (with/without spaces, underscores, caps) that I could think of of what appears in Disk Utility as "Maxtor SABRE."
Just to be clear - the only place I see any reference to the new drive is in Disk Utility. It's not on the Desktop or in Finder, and I couldn't find any reference to it in the Terminal.
And I also just noticed that the drive capacity is listed at 0 bytes in Disk Utility.
Perhaps this is simply a bad drive?
I also have a question in to the support site at Maxtor, and when I hear back from them, I'll post what they say.

Problems with second hard drive

I bought my PowerMac G5 new in 2005 and about two years after I got it, I installed a second internal hard drive. I didn't have any problems with the drive until about six months ago (which was when I moved, but I'm not sure if that has anything to do with it). Around that point, I started hearing a single, loud click followed by a slight winding down noise. Then, my computer would almost completely freeze. After a few moments, I would hear a bunch of soft clicks and my computer would go back to normal. I figured that it was a problem with one of the hard drives, but I wasn't sure what to do.
Later on, the problem got more severe, lasting more like 30 seconds. When my second drive unmounted during one of these episodes, I shut my computer down, opened the case, took both plugs out of the second hard drive, put them back in, and started up my computer again. After that, my computer was running great again. But, a few weeks later, the symptoms started up again.
So, I've gone through the same cable un-plug and re-plug process whenever the drive unmounts. Sometimes it helps and sometimes it doesn't seem to help at all. Altogether, I think that the second drive has unmounted about five or six times. I haven't had this problem at all with the original hard drive and I haven't noticed any other problems with my computer. (Well, okay, there's the rare occasion when, instead of going to sleep, it turns the screen black and puts the fans on full blast.)
Could the drive itself be going bad and it has nothing to do with the cables? I have a utility installed that always monitors the SMART status and it hasn't reported any problems. Are there any other troubleshooting steps I should take? Any advice would be appreciated. Thanks!

Before I bought DiskWarrior, I thought I'd try some troubleshooting with the software I have on hand. But while I was doing that, the problem got worse. Now, I'm having major problems just getting the computer to boot. I'll give you the rundown on what's happened. It goes through a few boneheaded twists and turns and goes on at great length, but I thought I'd relate it all in the hopes that someone can see a likely pattern.
My first thought was the Apple hardware test, which I had thought was on the Mac OS 10.5 install DVD. So naturally, I didn't see the hardware test listed under Utilities. But while I had it up, I used Disk Utility to do repairs on both hard drives (checking both the disk and permissions). It found no problems on the 2nd hard drive, but found a few errors with "leaves" on the booting drive. It also found a bunch of issues with the permissions, but I don't think it was anything out of the ordinary.
Just for the heck of it, I asked it to run the repairs again. Not long into that, I got what I think is a kernel panic (overlaid message saying I needed to restart my computer in a few languages). It also sped up the fans.
I pushed the power button to shut it down, then started it up again. I heard the startup chime, then nothing but a black screen and the ol' hyperactive fans. I went through that several times before I was finally able to boot from the DVD again. Then, I changed the startup disk back to my usual boot volume and restarted. I had to go through the black screen and insane fans several more times before I could boot normally.
Next, I thought I'd try OnyX to see what it could do. Which might not be much, but I had it repair the disks again and also had it run the daily, weekly, and monthly maintenance scripts.
I checked into the black screen & hyperactive fans booting problem elsewhere in the forums, and saw that it was recommended to run the Apple hardware test and also found the correct procedure for doing so, which was to insert the PowerMac G5 install disc (not the Mac OS X upgrade DVD) and press Option when booting. I loaded the disc, restarted, and held down the Option key, but before I could get anything to actually load, I had several more sessions with the black screen of fans.
Regarding that boot problem, I've sometimes seen the red light inside the case turn on almost immediately after I turn on the computer. Other times, it will not light up by itself. But, when I hold the power button in to shut it down, the red light briefly turns on before the unit shuts down. I've also noticed that the light on the Caps Lock button is coming on and staying on when I'm trying to start the computer.
So, after several tries, I checked my G5 User's Guide and it said to disconnect any external devices before trying the hardware test. I had a USB thumb drive plugged in and a FireWire drive hooked up for Time Machine backups, so I took both of them out. Once again, I tried starting up with Option held down and this time, it worked. The fans started running at full blast after I selected the hardware test, which I hoped was normal. So, I asked it to run the extended test and it found no problems. I restarted my computer without reconnecting anything and, at least for now, it's working normally.
Any new thoughts?

Pavilon 500-319na can I install a second hard drive

Operating System: Windows 8.1
I bought an HP Pavilion 500 - 319na desktop in summer and want to install a 2nd hard drive. There are spare connections on the board and the power cable to the internal hard drive has a spare connection. From what I read it needs to be SATA 3. I have read conflicting advice on this board. Some say yes, some say no.
OK, there seems to be only one bay (a poor oversight by HP) but provided I find a way of securing another drive is there any reason why it should not work.
From what I read it should be max 2Tb's.
I want a definitive answer please!

This is the hard drive I plan to buy. The spec says XP, Vista, Win 7, but am I right in thinking it should work with win 8.1

As I said to you in the other cross posting (desktop hardware):
You can obtain 3.5" hard drive cage from here for $11 shipped. Granted it has a 120mm fan and space for 4 drives, but for the price, you can mod/cut all you want.
Now your other issue/question: You will want a SataIII 6GB/sec drive 2TB, 7200 RPM.

Hello, I have a G5 PPC. I want to install a copy of Entourage on the second hard drive. Can I do that or will it create problems for the processor?

Hi everyone
I had a very old intel iMac from late 2006 which was dying now dead. I just managed to copy the Entourage folder onto an external hard drive before the iMac gave up the ghost. But I could not open the Entourage copy on the G5 PPC. each time i tried to do so the PPC copy of Entourage would open instead.I have emails on the PPC copy and do not want to lose them. I was wondering if it would be possible to install another copy of Entourage on the second hard drive? I was hoping that by doing that I could access the information from the iMac which has been copied to an external hard drive.
Any help would be very very welcome.

I don't think MS lets you install Entourage outside of an active system folder. However, you can install a fresh copy of Entourage on the G5's hard drive (if you have Office 2008 or lower), then use Entrouge's Import command to move the data files from the old hard drive.
We're done this several times as we've upgraded either computers or Entourage.
However, I think that, before you act, you should also ask in Microsoft's user forums here:

Cannot find a mounting to install a second hard drive in my Qosmio x70-A

I have looked all over the internet and have gotten no where in my search for a mounting for the secondary hard drive bay in my laptop. Anybody know where I can get one?

I have the same issue, and have found Toshiba support to be completely unacceptable on this.
After getting bumped around from sales to tech to sales because "we don't answer that question, you have to talk to the other guy", I finally got a "straight" answer from sales:
"Sir, we DO NOT sell that part, and therefore I CANNOT tell you a part or model number for the part you may need to install that second hard drive. The only thing you can do is talk to our parts supplier over at National Parts (1 800 524 8338) and ask them to provide you with the model numer or sell you the part."
At this point, I was annoyed, but thought that at least with a straight answer I could proceed.
After a very short hold time with National Parts, a very kind associate answered the phone and listened to my tale of woe. Unfortunately, she was unable to help and said:
"Unfortunately, sir, I have listed that while there is no caddy for the second hard drive slot on you X70-A specific model, there is supposed to be a mounting bracket. Unfortunately, we have been trying for MONTHS to have Toshiba give us the part number, spec, or any other information other than 'mounting bracket', and therefore I'm afraid we have neither a part to sell you nor a part number for you to go looking for one".
At this point annoyance is full-blown anger. How is it possible for Toshiba to make something that should be SO SIMPLE so VERY VERY VERY complicated and impossible.
"Sorry, if you didn't want to spring for the dual drives when you bought it, you're hosed forever sucker." Does not seem like an excellent customer service strategy.
This was the FIRST Toshiba I'd ever decided to spend my hard-earned money on, and now it's a machine I can't upgrade because they can't get their act together with their parts supplier or in-house over a 3 dollar bracket?
UNACCEPTABLE.
The pictures the original poster shows are exactly what I have, no need to add more o fthe same.
ANY help, Toshiba?

Can anyone recommend a second hard drive for my PowerPC G5

Hi,
Sorry if this question has been asked before but I need the answer in a hurry.
I need to fit a second hard drive into my PowerPC G5 - and I have never done this before. I phoned a company to buy a drive and they said that there can be compatibility problems with certian drives and Macs. A friend at work also confirmed this and pointed me to the site www.xlr8yourmac.com which has a database of drives and their associated problems.
Unfortunately I don't have time to digest all of the info. I am letting a friend use my Mac for a project that they are working on and they need the space urgently. They are working to a strict deadline.
So basically what I would like to know is if anyone can recommend a drive that I can fit without it causing any problems. I need a high quality, fast and very quiet drive for audio and video production. The drive should be 250GB, 7200RPM, 16MB cache. The Mac support pages say it must be a serial ATA drive but I have no idea if you can use ATAII or ATA300 (or any other number???).
Also - as I have never done this before - I have heard 'jumpers' mentioned - will I need to set the jumpers to a particular configuration?
Thanks in advance, Byron.
