Low on space on internal hard drive

Hello - I hope this is the correct forum to post to. My iMac G5 came w/the standard 80GB (74.41GB) hard drive. It is now down to only 3.87GB of free space. All of my video media is on my external Lacie Drive, but since I have such little space left on the computer, I'm not able to use my system to burn videos, etc... I have tried clearing out all of the unnecessary Applications and files that I'm not using, and emptied the Trash and that doesn't seem to free up much space. I did download Onyx but am unsure as to if/how that might clear up space - would anyone recommend this? Also, short of buying more RAM (I have 1GB of RAM), might there be any suggestions as to how I can free up more space? Thanks so much for any suggestions!

Hi Kristina: I just checked my HD to find "log" files. They are located in your User Folder > Library > Logs. Mine are under 1mB, which I believe would be about the norm. They also show up within WhatSize. I checked the Onyx program and below is what it says about its function:
"OnyX is a maintenance, optimization and personalization utility for Mac OS X (PowerPC and Intel). It also makes it possible to configure some hidden parameters of the Finder, Dock, Dashboard, Exposé, Safari, Login window and of some of Apple's own applications, to remove some files and folders that may become cumbersome, to preview various logs and CrashReporter-reports, and more."

How to free up space on internal hard drive

How do I free up space on my internal hard disc?
I have only about 40 gig of information on my macbook however it says I don't have space while I'm working on photoshop. I have deleted a lot of files on my mac that are already saved in my external hard disc but when I check my memory it says I have only 1.3gig space available out of a 120gig memory. This data is distributed between audio, apps, movies, pictures and other. I don't understand what 'other' is and it says I have about 76gig worth of data in the other part. Please I would need help on how to delete files from this 'other'. Cheers!

All Mac operating systems use any free space on your hard drive as virtual memory, and this virtual memory plays a part in how well your computer performs. Because of this, the more data you have on your hard drive, the less virtual memory becomes available. Therefore, in order to help increase your Mac boot time, and keep your computer running smoothly, periodically cleaning your hard drive is necessary. To clean it up you want to get rid of any old or unnecessary files. You can do this manually by removing unused applications, emptying your trash etc.,

Clearing up space in internal hard drive

So my macbook has been notifying me that my hard drive is full. So I bought a Passport 1T external hard drive. I had Time Machine do a back up on it already. So now can I delete things in my internal hard drive to make space on it. Will my backed up data in the external hard drive be safe and I will be able to retrieve it? I'm not a computer person so I see the external hard drive like a USB.

Files only in a Time Machine backup on that drive may be deleted if it runs out of space, and the drive can fail at any time. Put your documents on a second external drive and set Time Machine to back it up as well.

Lost 14 gig of space on internal hard drive after backing up photos to dvd's

good Morning, I'm running pse 6 and yesterday I did a full back up of my pics which is about 14 gig onto dvd's. This morning when I checked my free space available on my hard drive I was missing about 14 gig. I normally only have about 20 gig of free space left on my hard drive so I can't afford to lose 14 gig. Did backing up my pics on dvds also eat 14 gig of space on my hard drive? Help!
Bill III

well probably you have told PSE to back up your entire hard disk , first check out the disk space usage and all by downloading any disk space usage analysis software..probably that will give you some help.

How can I find out how much free space on my hard drive?

I recently upgraded to Lion but still a newbie to Mac OS X. I need to be able to check available space on internal hard drive.

Hi ...
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure there's a minimum of 15% free disk space.
You'll see Capacity and Available from the Get Info panel.

I'm running Final Cut Express 2. How can I move entire project and application from one internal hard drive to another? Ran out of space on one drive. Thanks.

I'm running Final Cut Express 2. My video project is 95% done and I've run out of space on my 500g internal hard drive. How can I (1) move the complete FCE program and video to my unused 250g internal hard drive and operate it from there and (2) how do I then purge all the FCE info from the 500g drive without losing anything from the 250 drive?
Also, is it possible to change the aspect ratio from 4:3 to 16:9 when the project is finished? If so, how? I now know this all should have been done before I started. Thanks for the help.

1. You can't move the application. It must remain on the system drive. Move your capture scratch folder to the external FireWire drive and use the reconnect function in the project.
2. What's the media 16:9 or 4:3?

Internal Hard Drive Free Space Issue

Hey,
I recently upgraded my 17" MacBook Pro from Tiger to Snow Leopard but the upgrade seems to have created a number of problems, the most notable being the lack of free space now available on my internal hard drive.
I also had to install a trial version of Aperture 3.0.3 in order to access my aperture library as the older version of Aperture is not compatible with Snow Leopard.
At this point the free space available on my internal hard drive was 36GB and my aperture library was 39GB. I had to uninstall Photoshop Elements 9 in order to create enough free space to open this library.
I bought an external hard drive and after some organising (importing and exporting to and from external hard drive), I eventually moved all photo files/folders, projects and libraries onto this external drive, leaving only one in-progress project (about 3GB) left on the internal volume.
I also exported my iTunes library and any other files to this external drive.
All trashes have been emptied.
The problem is that, despite all this clear-out, I now only have 2GB of free space on the internal hard drive.
I ran Disk Inventory X and it shows that my home folder is using 155GB of space, which seems ridiculous considering there is in effect nothing left on my laptop save for the application programs and the one remaining project.
I have manually checked through this folder and all its subfolders and have found nothing that would accumulate to this amount of space.
I have repaired an issue with the internal volume, but it is now showing a “minor” problem with the volume header.
If someone can provide and explanation/solution to this I would be very grateful as it is severely slowing my workflow at the moment.
Thanks

Baresi:
I suggest that you begin with Repair Disk
Insert Installer disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu (Panther and earlier) or Utilities menu (Tiger) and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
(Check S.M.A.R.T Status of HDD at the bottom of right panel, and report if it says anything but Verified)
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
If DU reports errors it cannot repair you will need to use a utility like Tech Tool Pro or Disk Warrior
I recommend that you make sure that you make a bootable clone of your entire volume using a utility like SuperDuper or Carbon Copy Cloner.
You should also seriously consider installing a larger capacity drive.

Making space on my internal hard drive.

I have already been using Time Machine to back up everything on my Imac using an external hard drive.
I have now purchased a second 1TB hard drive that I want to use to back up only my photos on Iphoto & film on iMovie.
The intention is then to delete them from my internal hard drive to create more space.
Can I use Time Machine for this 2nd hard drive as well, ie. to selectively copy files (photos & movies).
If not - what's the easiest way to move photos & movies from iLife to a second hard drive?

Make sure the drive is formatted Mac OS Extended (Journaled)
1. Quit iPhoto
2. Copy the iPhoto Library from your Pictures Folder to the External Disk.
3. Hold down the option (or alt) key while launching iPhoto. From the resulting menu select 'Choose Library' and navigate to the new location. From that point on this will be the default location of your library.
4. Test the library and when you're sure all is well, trash the one on your internal HD to free up space.

Can anyone give step-by-step instructions for moving my iPhoto library to my external hard drive to free up space on my internal hard drive?

I want to move my iPhoto from my internal hard drive to an external hard drive to free up space. Can it be moved entirely and function the same as before with all features and the software itself on the hard drive? Also, can anyone give step by step instructions on how to do this? I'm having a difficult time figuring this out on my own by trying to search through Apple support.

My MacPro says the startup disk is too full. I have 4 internal hard drives that have 2T each so there is plenty of space, but all start up programs, libraries, iTunes and application folder are on the '1st' hard drive. Can I move any to 2nd drive?

Your system will likely fit just fine on a small fast 250GB SSD
What you have is lots of stuff that should not be on the boot drive, data and graphics or media files and libraries that should be moved to another drive.
If you are getting a message like this, STOP, off load files, make room, and make sure to have 15% free or more.
Do not try to move anything from system and its library and sub folders. Move your home user account and just leave the essential home library but move all the rest.
A full drive can have trouble finding free space segments and writing out updates to files and to the directory. And loss of directory means loss of where files are located and their segments.

How do you move or can I move Itune folders (Movies), (TV Shows) and (Home Videos) to other internal hard drives (running out of space) on my computer's main hard drive and have Itunes recongize where they are?

I built my own computer which has 4 internal hard drives with 3 internal hard drives that are 3tb. With my movies and tv shows, I need to know if I can move the Itunes folders (Movies, TV shows and Home Video's) and move each one of them to 3 seperate internal hard drives while Itunes can still find them to play with my apple tv. Does anyone know how I can do it?

While you can do that, it is not a feature of iTunes. Put your movies on the external drive, then add them to iTunes by dragging the files to iTunes while holding the option (alt) key down so it leaves the files where they are located. There are other ways to move them if they are already added but they can be more involved and tricky. If it's just one or two try: http://dougscripts.com/itunes/scripts/ss.php?sp=relocateselected

What brands and type can I use for my iMac 20" internal Hard Drive?

what brands and type can I use for my iMac 20" aluminium internal Hard Drive?
can I use WD caviar black?
is it too hot?

If you are replacing the drive because the existing one is faulty, that's one thing. If you just want more space, you should take advantage of having a decently fast and relatively small capacity drive in there now (instead of a huge drive). Get an external FireWire drive and off-load most of your user data there. Make your internal drive dedicated to mostly your OS and app files, with plenty of free space. That setup will make your iMac run more efficiently. I won't go into more detail, because I'm not answered your specific question... You can post back with any questions, if interested...
To answer your questions...
You should be able to use any SATA 3.5-inch drive internally, but you should probably keep it at or under 1TB. The main concerns are power usage and heat dissipation. A drive like the WD Caviar Green would be ideal in terms of power and heat, but they do have slower (or variable) spin rate. I have one as an external drive (750GB) and it is amazingly quiet and cool. If I had to replace the internal drive because the current drive failed, I'd put it inside. I'll trade a bit of pure performance for the efficiency (including low noise), and these drives are more advanced with higher data density and larger cache, so the trade-off from slower spin rate may not be so bad.
You can check your current drive's model number (which is shown in System Profiler) to get the specs online. The stock drive in my old +Late 2006+ iMac is a 7200 RPM drive. The Caviar Black is a 7200 RPM drive, with a newer design. So if you want to use a Caviar Black in there, I think it would be OK.

How to move an iTunes library from the internal hard drive to another bootable disk.

         I got two Mac OS X installations on my i Mac system. One on the internal hard drive (320 Gb), that has been there since the iMac was bought 3 years ago, upgraded to Lion on 2 August. (call that INT) . I have a USB external drive, and recently bought a firewire Lacie external drive (2Tb), so to boot from there when I can, with hard drive space getting tight this year. I successfully installed another copy of Lion on LACIE.
         Then I went to work to transfer my iTunes library, which the media files were optioned to store on the USB drive. Intending to transfer both the music and video files, and the megadata ( playlists, ratings, playcounts ) I found the media files and the iTunes library file and the .xml document in my iTunes folder from INT. I made a new folder in the USB drive, and copied the contents from the old iTunes folder to that new folder. I re-started in LACIE, and found my empty iTunes folder. I copied over to the new iTunes folder, then opened iTunes. My eyes saw the music library to the same number of items, with the playlists etc showing.
        However, I tried to sync an iPod Nano, and a window came up saying 100 songs could not be copied to the iPod because they could not be found. After ejecting the iPod I tried to play a song from iTunes, and the screen filled with exclamation points. A small window came up, asking for a password to open "sparsebundle" and my name. I entered my password for the administrator's log-in and it said try again with the password. Without knowing what password to put in, I clicked Cancel, and got another small window asking to locate the file. Then clicked Cancel again, not knowing where to search. All the media folders were showing after quitting iTunes and opening Finder .
      I re-booted into INT, and opened iTunes. The library was still there. I synced my iPod again, ejected it, played 3 songs on the iPod, synced again, ejected it again, and opened the playlist "Recently Played". It showed up okay with no problems. So my iTunes library in INT is alright.
      Has anyone got any idea how to make the transfer into LACIE and get it running alright, or what went wrong with what I did ?
      In the meantime I will empty my LACIE iTunes library folder's contents to the trash, and securily empty the trash .

Solved the issue without using the trash . I tried to consolidate the library in LACIE, then clicked on any exclamation-mark song and tried to locate the file. Repeating those steps 3 or 4 times cleared it up. That was confirmed when I synced the entire library on a iPod Classic, and showed up no problems after syncing the Nano.
     What went wrong was perhaps to fail to consolidate the library at first .

Internal Hard Drives Disappeared, Finder Memory Problem

Hello Helpful Folks,
I recently installed an addional internal Hard Drive, and an additional 1GB SDRAM. This worked great for a day, but the next morning, after powering up, system was extremely sluggish, and after much deadline-induced impatient problem solving, has gone from bad to worse (system refuses to acknowledge existence of internal Hard Drives). I apologize in advance for the length of this post, but as
the devil is in the details, I figure too much info is better than not enough.
Following is a breakdown of my system: AS IT LAST WORKED; RECENT UPGRADES; and MY LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE. Please don't interpret my all caps as shouting, just trying to organize this post for better clarity.
System is dedicated to Video Editing with FCP 3, running under OS 9.2.2. System is "off the Grid", i.e. no network, no internet, no printer, no gaming devices. System was purchased new in July 2001, by a friend. At one point I know this system had an Airport card, which was removed prior to my purchase in 2003. I can't remember what else it may have had installed in its history, but here's what it has now:
SYSTEM AS IT LAST WORKED:
**bold items are upgrades Original Owner or I installed with no apparent problems**
Power Mac G4 "Quicksilver" 2001
867 PowerPC G4, 256 L2, 2MB L3
-1 Stick "ValueRAM - KVR 133 x 64 C3/512" in PC 133 DIMM slot **
- "Virtual Memory" was turned off years ago due to conflict with FCP 3
-2 empty DIMM slots
-1 60 GB internal HD (Maxtor Ultra ATA/100), 1 partition, formatted HFS+, jumpered as "Master" on Internal ATA 2 ID=0 (which as I understand it is ATA/66 speed)
-1 Pioneer "Superdrive" DVD-R/W/CD-R/W on Internal ATA 0 ID=0
-NVIDIA GeForce2 MX with 32MB SDRAM in AGP Slot, feeding a 17" Apple Studio Display.
-PCI Display Card "formacGA7" - not attached to any external device, not sure what its intended purpose is.**
-3 Empty PCI Slots
-OEM Keyboard attached to Monitor's rear USB port.
-Microsoft 3 Button Wheel mouse with "IntelliEye" (wheel is 3rd Button) connected to Keyboard USB port (right side).**
-2 OEM FireWire (400) ports
-2 OEM USB (1) ports
Peripherals that have worked in various configurations with this system over the past 3 years:
-3 OWC Mercury Elite ("Oxford Chipset") Externally powered, External FireWire(400) 200GB Hard Drives, 1 partition each, formatted HFS+, daisy-chained to either of the FireWire ports.
-1 Canon GL1 MiniDV camera, attached either to the other FireWire port, or to the last drive in the chain, depending on my urgency/laziness factor. BTW, FCP 3 has worked flawlessly controlling this Cam for logging and Batch Capturing.
Applications on System Hard Drive that I have OEM CDs for:
-OS 9.2 - (I think I remember that OS X was removed from system due to conflicts shortly after original purchase)
-FCP 3
-DiskWarrior (version unknown, purchased from Alsoft in 2003)
-OWC Intech Hard Disk SpeedTools ver 3.5
Other CDs I have:
OEM CDs for Power Mac G4:
-Software Install, OS 9.2, CD vers 1
-Software Install, OS 10.0.4, CD vers 1
-Software Restore, OS 9.2 & 10.0.4 CDs vers 1, Discs 1-4 of 4.
-OEM Apple Hardware Test; Power Mac G4, SW vers 1.2.1
Applications on system Hard Drive that I don't have CDs for, that I rarely use, but I'd like to keep:
-After Effects 5.0
-QuickTime Player 6.0.2
-Toast Audio Extractor 1.1
-Toast Titanium 5.0.2
Applications on system Hard Drive I use if my wife is busy on our Windows XP machine:
-Photshop 6.0
-Microsoft Word & Excel
# of other Applications on System Hard Drive I either don't use or may be integral to the system: 260
# of Control Panels:
-Enabled: 34
-Disabled: 0
# of Extensions:
-Enabled: 174
-Disabled: 0
note: a number of the applications and extensions are for AOL, Quickbooks, Microsoft Money and the like, as well as other things I don't use (Airport, USB printers, Networking, etc.)
Smart things I did:
-Regularly made backup copies of my FCP projects to the external drives.
-Bought a copy of MacDrive so I can see what's on my External Drives on the XP machine.
-Printed out System Profile before I installed upgrades.
-Thoroughly searched this discussion board for and gathered as much info as I could before upgrading.
Dumb things I did:
-Made a copy, but not a clone, of my System Folder to one of the external drives when I first got it.
-Didn't keep any sort of separate log of what's on the External Drives.
-Never ran any sort of Disk Maintenance, even after one of the Externals crashed (DiskWarrior saved my butt on that).
-Ignored some of the advice on this discussion board.
Really dumb thing I did without even realizing it:
Captured all media for a rush job onto my internal system Hard Drive, as well as storing and using massive jpgs for the same job on that same drive...
Which led to painfully slow rendering times, and crashes caused by "Error: Out of Memory", which I interpreted as "Must buy more memory" and not "must make sure I'm not trying to edit media stored on system drive, especially with massive jpgs that I should reduce"
RECENT UPGRADES:
Here's what I did, and how I did it:
Turned off system, disconnected all External FireWire Devices, disconnected Monitor, opened case, touched various metal parts of case and power supply to discharge any Static, unplugged power cable.
-Installed 2 512MB sticks of "Lifetime" PC 133 SDRAM; total System RAM is now 1.5GB, all 3 DIMM slots now occupied.
-Installed 1 Maxtor "DiamondMax" Ultra ATA/133 100GB Hard Drive (8 MB buffer) as "Slave" (no jumper) in top of U-Carrier above System Hard Drive; attached to middle of original Apple ribbon cable, attached available power plug.
Taped spare jumper to inside of empty drive bay, noting origin and date. Did NOT push PMU button. Carefully closed case. Reconnected Monitor, did NOT reconnect any FireWire devices. Powered System on, but did NOT perform PRAM reset.
I don't remember the exact order of what happened next, but I think: System booted up normally, a window popped up saying a new drive had been found, would I like to intitialize it?, which I did as Mac OS extended, and then named. If I was instructed to restart, I did so, otherwise did not. Clicked on "about this Mac" and saw that it now showed 1.5GB RAM. I then went about moving Media/Render files off the System drive (and one of the Externals) onto the Internal Drive, with a combination of FCP's Media Manager, and dragging from the Finder. After files had copied, dragged Media/Render files from System Drive to Trash. Opened FCP project, had FCP re-link to new locations of missing files. Saved, closed, and re-opened project, set Capture/Scratch disc to new internal Drive. At some point I changed FCP's Memory Allocation from whatever it was to 512000KB Minimum, and 900000KB Prefered (and I hope I got all those zeroes right). Did NOT restart after changing Memory Allocation, unless a window popped up instructing me to do so, in which case I did. Re-opened my project, rendered a few thing at a noticeably increased speed, saved everything, emptied the Trash, shut everything down, and called it a night as it was 4:30 am.
A few hours later, I plugged the MiniDV and an External Drive into the FW ports and powered up the System. It was behaving extremely sluggishly. I would click on something, the pointer would turn into a wristwatch (sometimes with the minute-hand moving, sometimes not) and like an actual minute later, what I'd clicked on would open. All three drives were on the desktop, still had their files, and "About this Mac" still showed 1.5GB total Memory. So I powered down, disconnected the FW devices, waited a bit, and powered back up. Same sluggish response. I tried to open my FCP project file, and instead got a Window that said something to the effect of "The Application associated with this document could not be found". I think I tried to open FCP from the Applications folder on the System Drive and got the same message (I'd only had 3 hours sleep, no coffee, my client had died, and his family was coming for whatever I had in a few hours).
LAME ATTEMPTS AT PROBLEM SOLVING THAT HAVE MADE THINGS WORSE
Panic had set in, which never solves anything, so I don't remember what order I performed which tasks, between searching for clues in this forum, and convincing myself that that would be faster than trying to compose a question, waiting for a response, etc.
The first two things I did, and I can't remember which I did first (both from Keyboard Commands during Restart):
Rebuild Desktop
PRAM Reset
Neither of those solved the problem, so I continued.
I tried restarting without extensions.
I would get errors that said something like "Not Enough Memory to Open Finder".
I tried booting from Disc 1 of the Software Restore Disk, which only wanted to destroy my data.
I tried booting from the OS 10 disk, with the same result.
I was finally able to boot from the OS 9.2 Software Install Disk, and actually saw both internal drives on the desktop, and the 1.5GB RAM in About this Mac. I tried to allocate more memory to Finder, but was informed that "Cannot Perform Requested Operation. This operation requires versions above 8.0".
I think at this point I decided that I must have too many extensions, and started disabling ones I thought irrelevent to my cause (mostly anything that said "AOL", "Airport", "Ethernet", "Printer", "Modem", "Speakable", and a couple things called "Open TPT".
It gets worse. Then I decided to turn off some "unnecessary" things via the control panels, but somehow managed to disable the control panels themselves: AppleTalk, DialAssist, File Sharing, Modem, Mouse (as I saw that Microsoft Mouse was among the others), Remote Access, Speech, USB Printer Sharing, and possibly TCP/IP.
That certainly didn't help anything (though upon restarting from the OS 9.2 Disc I was able to see the extensions and control panels in their respective "Disabled" folders in the System Folder). But I still wasn't able to get more Memory to Finder.
So, I decided a few more PRAM resets might help, which succeeded in making both Internal Hard Drives disappear. I tried booting up from the DiskWarrior disc, but even the Mighty DiskWarrior couldn't find the drives. I performed the longer, in depth version of the Apple Hardware Tools tests, which reported that everything's fine (including the new RAM), but made no mention of the Hard Drives at all. The deadline having long passed, I shut the system down. I read through more posts and tech articles, etc.
I searched my External drives with MacDrive on my XP, and found the drive that has the copy of my System Folder (which shows all extensions and control panels as enabled); not sure if the Quicksilver will boot from that, I don't know what the Keyboard command for booting from a FireWire drive is (if there is one) and the drive itself only has 900MB of free space.
I can't find any reference to Internal ATA drives anywhere in the MacDrive documentation; if it was possible I'd put them into the XP, get the files off the Mac drives, reformat them and install OS9 from the Discs.
This is where I am now:
The Quick Silver is still powered down. I removed the Microsft mouse and replaced it with the OEM Apple mouse. I opened the case, and removed the PRAM/Backup battery (manufacture date: July 2001). Couldn't find my voltmeter, so took the bat to Radio Shack and bought a new one. Had the Radio Shack guy test the old one: it showed 3.69 volts still. Have not installed the new battery yet. The case is still open, waiting for any advice any of you might have to offer.
Thank you all so much for your patience in perusing and pursuing this.
Sincerely,
Patterson

Thank you Rodney and John,
The jumpers are correct for both Maxtor Drives.
Rodney, you are correct in that the initial problem (slow rendering/"out of Memory" crashes) was caused by my not realizing I'd stupidly captured several GBs of media to my system drive, and not checking which drives those files were on (as I'd assumed I'd put them on one of my external media drives) once that problem presented itself.
Before I'd determined what I'd done, I bought the extra RAM. After I'd found the media files on the System Drive, and saw that my dedicated media drives were too full to easily move them, I decided to buy an additional Internal drive so that I could:
-Move the Media onto it relatively quickly and finish my urgent project.
-Juggle all my media into a more organized fashion for archiving (as most of my projects are on-going long-term affairs)
-Wipe it, Partition it, and clone my System Drive onto it, as a spare bootable drive in case my OEM System Drive failed.
Copying the Media files onto the New Drive and moving the System Drive's Media files into the Trash worked great: huge improvement in Rendering, etc.
Before shutting down for the night I Emptied the Trash, and was pleased with the amount of space I'd freed up on the System Drive.
My guess is that the System Drive was terribly fragmented, having been subjected to intense use over the past 5 years without any sort of Drive Maintainence, and deleting that massive amount from it in one shot caused my extreme system sluggishness upon Startup the next day.
My subsequent lame attempts to solve the sluggishnes ultimately resulted in my losing access to both drives.
Today, I replaced the Backup Battery, pushed the PMU, re-attached the AC, and Powered Up with the case open as per your suggestion.
It was trying for a few minutes (the gray screen went black at one point, and then returned to gray) before presenting me with the flashing question mark.
There was, however, a quiet but distinct "buzzing" sound that would alternate: 1 sec "buzz", one second silence, one second "buzz", one second silence, etc. coming from the drives, even after the "?" appeared.
I powered down, removed the Ribbon and Power Cables from the new "Slave" drive, and powered up again, with the exact same results.
I powered down, removed the Ribbon and Power cables from the original "Master" drive, reinstalled the Jumper on the New Drive as "Master", plugged the End of the Ribbon and the Power cables into the New "Master" drive and powered up. The screen went to the "?" within 20 seconds instead of 4+ minutes, and no more "buzzing".
I put the Apple Hardware Tools Disk in, ran the "long" test, and everything came out fine.
I have to abandon this for now, but thanks again for your previous advice, and any more you may have!
Cheers,
Patterson
