G5 won't recognize 2nd hard drive

Installed a 2nd drive, Hitachi SATA Deskstar HDS721010CLA332. It powers up but is not recognized by Disk Utility nor in Serial-ATA Device Tree. Data cable is set properly; seems to be set in motherboard. Makes alot of noise during OS startup, then quiets down after I login. Any ideas why it's not recognized? My G5 is PowerMac 7,3.

Great info as always ocg, fo keep us posted if you find out more!
I am due to swap the drive in the lower bay with an offsite drive in a day or two, and I will be curious to see what they other drive reports for a model number, as I believe it was purchased at the same time as the seemingly SATA-3 drive. The model number for the lower-slot drive is for the new higher-capacity drives that are 3TB, 2TB or 1.5TB. Veerrry eenteresting, as Arte Johnson would have said. (As an aside, Hitachi doesn't seem to put the actual model number on the retail packaging.
It does seem that it's supposed to auto-negotiate at least SATA 2 to SATA 1, so it does seem like a bad drive so far.
If truly the cable swap that the OP reported was such that the boot drive was now connected through the second cable to the second SATA plug, then I would say the smart money is gonna bet on a bum drive. The K2 chip could be the problem, but that seems to have been eliminated by the drive swap on the cables. Since the drive should work but it doesn't, the boot drive works on both interfaces, the OP should take it back and try another one. Infant mortality is not an impossible event.

Hi, since i put some mp4 video or DVD files on my external hard drives final cut prox won't recognize my hard drives, i move all the video files and the problem still exist. somebody have the solution

Did the back and forth between PC and Mac file systems screw up my files somehow?
Yes. Unfortunately the move has almost certainly caused the loss of the resource data that would have been (invisibly) attached to those files.
By adding a specific .mov extension after the fact you will have helped the Mac correctly identify the file type / asscoiations but also significantly you will have physically changed the filename eg from "clip" to "clip.mov". This means that when you come to reconnect the media in FCP , then FCP will be looking for files that no longer exist at the given path eg when specifically looking for our example clip called "clip" of course it won't find it.
Try this as a test... first remove the ".mov" extension from one or more of the clips, select those clips and press Cmd-Opt-I to open an Info window for the selection. You'll see an "Open with:" popup and in that popup you should choose QuickTime Player (if its a Unix Executable then it will initially list Terminal as the appropriate app, you have to choose Other... then in the open dialog choose Enable > All Applications and then navigate to and select the Quicktime Player app as the appropriate app). After you've done that restart FCP and see if you can now reconnect to those clips.

Os9 not recognize 2nd Hard drive

Hi there,
I work under OS9 and put a second Hard dive in it
On startup I dont see it in the main screen,
Can anyone tell me whats wrong or can tell me how OS9 will recognize the hard drive,
I formatted it as OS9 extended
regards
John

Hi, Musicman40 -
Try connecting the Master drive to the end connector of the ATA cable, and the Slave drive to the middle connector of that cable. Although this should not be necessary, it sometimes works better.
Isn'there a way to copy the systemfile of os9 to the other Hd on startup??
There is no system file as such (there is a file named System, but by itself it is not usable for anything); perhaps you mean the System Folder? OS 9's System Folder can be copied to another volume via drag-and-drop and still retain its functionality.
I don't know of a way to cause that copying to occur automatically at startup. In all probability doing that to a drive which is not visible to OS 9 won't change anything - it will still be not visible.
There is a restriction applicable to your model for drives 8GB or larger, as described in this Apple KBase article -
Article #25249 - Gray or White Screen After Hard Drive Upgrade
That restriction applies to using such a drive as a boot volume; in order to do so, it must be partitioned such that the first partition is slightly less than 8GB, and all OS's for that drive then placed in that partition.
Although that restriction should apply only when using the drive as a boot drive, it would not hurt to test your situation by partitioning it to see if that makes a difference. Be sure to install OS 9 drivers.

Disk Utility won't recognize new hard drive

Hello,
Thanks for taking the time to read this.
The original hard drive (80 GB) went bad, so I replaced with a new 160 GB Western Digital one. I formatted the hard drive using Disk Utility from the Mac OS X Disk. It worked the first time I booted into Leopard (I just booted up to make sure the OS loaded...didn't install any new software and/or hardware).
Then I shut it down and started it back up, and the computer didn't recognize the hard drive. I inserted the Mac OS X disk and ran Disk Utility, but the hard drive was not recognized.
So now I'm thinking the new hard drive was also bad. So, I ordered another one (Seagate 160 GB) and it to was not recognized when I ran Disk Utility from the Mac OS X disk.
When replacing all of them, I followed directions I found here and other websites. They all said to do it the same way, so I'm assuming the directions for replacing a hard drive in a laptop were correct.
I searched Google and found several posts suggesting using an application called Disk Warrior, but from my understanding, you cannot run it from a disk, it needs to be installed, which is obviously impossible since the hard drive isn't recognized.
Then I ran Open Firmware and did "devalias" from the prompt. From what I can tell in the list of hardware, the hard drive is recognized, but I am not sure. I took a picture of the screen printout but do not see an option to attached it to this post. Therefore, I'll just tell what it said for now and will create an image hosting account so I can add a URL for it later.
In the list, "hd" is in the left column and in the right column of the same line is "/pci@f4000000/ata-6@d/disk@0" (without quotes).
If anybody has any suggestions, they would be greatly appreciated.

Welcome to the Apple discussions.
I've replaced a few hard drives, and in instances where it's not recognized, it's either been a cable connection issue or I've seen others with a jumper issue. Either the hard drive to logic board cable isn't properly set, typically on the logic board side, or a jumper was left on the drive, where typically you can just remove it. I haven't personally had the cable fail, however, that's possible too.
When you pulled the large plug from the back of the original hard drive, did you do it very carefully? It's not like a desktop hard drive plug that you can just pull out ... it needs to be wiggled out, gently. I have a hard time believing two new drives would be essentially DOA, although the first one worked for a bit, which leads me to wonder about the physical connections.
Since you have your original OS X disks, you could try running the Apple hardware test to see if it gives you any error message(s).

Migration Assistant Won't Recognize External Hard Drive

I have a PowerPC G5 and made a bootable backup of the computer's content to an external firewire hard drive. I tested the backup to make sure that it booted and everything was fine. So, I then did a clean install of Leopard to the machine. After the computer restarted, I reconnected my external drive and it mounted fine. However, when I went to use Migration Assistant to bring over all of my applications, it would not recognize the hard drive as an option to migrate files from.
The hard drive is formatted as Apple Partition Map, and works fine as a bootable copy. Does anyone know why Migration Assistant will not recognize it?
I recently did a clean install of Leopard on my Macbook this weekend using a different external drive with a bootable backup of the drive (GUID formatted) and then used the migration assistant to move all of my files and everything worked just fine.
I can't find any reason that I shouldn't be able to get my applications through migration assistant from the external hard drive but maybe someone knows how to fix this or of a workaround.

Very curious, indeed.
Welcome to the Apple forums where we do try to sort things out
Your delineation of the problem and comparison to your MBP is perfect.
I migrated my G5 from a second internal disk, but actually used the setup assistant when Leopard came alive.
You might see what happens if you eject your external HD and then do what you need to to connect it back (turn off/on - unplug/plug, etc.)
Are there any errors when Migration assistant runs?
It is perhaps that Spotlight is doing its thing and the drive is not available until it is indexed?
I would remove the external HD temporarily from the SpotLight indexing list and then see what happens.
I recall that there were some odd issues with external drives taking up to 1/2 hour to be recognized by Leopard, but I don't recall why.
I am not sure these things will help, but they will eliminate some of the possibilities, and when we have eliminated the probable, what is left is where the answer lies
I wonder if Leopard is confused by the external drive not being GUID?
Try this - - connect the GUID external drive to your G5 and see if Migration assistant sees it. Obviously do not migrate anything, but if you can see that one, we may have a solution.
Keep us posted.

Macbook won't recognize external Hard Drive and issues with Time Machine

Hello everyone,
I have just bought a new Macbook Pro with Mountain Lion and I am currently having problems with Time Machine.
The issue begun in Snow Leopard: Time Machine was taking too long to backup, and would often not finish the backup because the external hard drive would be unwillingly ejected.
Now with Mountain Lion I have reformated the drive (Mac OS Journaled) and about a third of the way through had the same issue: the drive was ejected before the backup could be finished. I restarted the machine and it happened again. However, now the computer won't even recognize the external drive when I plug it in. I have also tried to power off/on the drive itself to no progress.
I have tested the USB port with another drive and the port is fine. I have also tested the usb cable and it is fine. And Disk Utility does not recognize the drive (even when I try the >diskutil list command in terminal).
Now, I can hear the drive humming normally when I turn it on, and it is not usb-powered (my electricity current does fluctuate).
Could the interrupted backup procedures have damaged the drive? And if so, wouldn't the computer recognize it anyway?
It is a 4 year old WD 1 TB that is used exclusively for TM and has never left the house.
Thank you for your time reading this and let me know if you need any more information that could help out.
Cheers!

From your description, I'd suspect a failing drive. Maybe time for a new external, especially as you've already re-formatted and it's still playing up.
I had a similar problem with one of my clone backups a few weeks ago - it failed, I erased it, re-cloned, worked a couple of times and then it failed again. Disk Utility didn't throw up any errors after re-formatting. I guess all disks die at some point.

IMAC won't recognize external hard drive anymore

I am running snow leopard on my IMAC with all the latest software updates. I've been using a LaCie Quadra external hard drive with time machine for backups for awhile with no problems. From the beginning is was plug in the hard drive and go, the mac recognized it. Now, suddenly, it won't. When I turn on the LaCie to back up, the icon no longer pops on the desktop. It is also not listed in the Time Machine preferences anymore. I tried to open the LaCie from Mac systems preferences and get a message with something like "64 bit cannot recognize 32 bit" I am asked to close and reopen system preferences, which would change to 32 bit. I tried that and it did not work,and a report was sent to Apple. Has anyone else been experiencing this? Thanks

Thanks. I don't disconnect the drive, only turn it off with it's own power switch. According to LaCie, this should not be a problem.
No, it's not a problem for the drive, but neither is leaving it (and Time Machine) on. Most externals will "spin down" after a few minutes of activity, but even if they don't, modern drives are built to run 24/7.
Time Machine was designed to do quick hourly backups of changes, and will protect you best that way. Just leave both Time Machine and the drive on; they'll be fine.

Satellite A135-S2356 - BIOS won't recognize SATA Hard Drive

Hello everyone, hope you can help me out.
Got a used Satellite A135-2356, everything looks fine but BIOS won't recognize SATA HDD, shows no disk, downgraded BIOS to 1.30, no good, upgraded to 1.40, no good. BIOS has no options to change/test/detect HDD/SATA settings. Tested hard drive in another laptop and reads it fine. Got restore CD (Vista Basic 32) from Toshiba but since BIOS won't read HDD, can't do anything. Cleaned contacts, no good. This HDD must be too large or something for the board.
*Hitachi HTS541612J9SA00, 120GB SATA, 5400 RPM*
Thanks for the help!!!

Hello Richie
To be honest I do not believe the HDD is too large for your notebook. I can imagine your notebook can handle with 160 GB HDDs too. Unfortunately there is no public document about HDD upgrade possibilities. I can imagine that ASP in your country has info about this stuff.
It is also pretty strange that HDD is not recognized properly. Long time ago I have had the same problem. Every time when I have used F12 at the start up HDD were not listed as bootable device. Solution in my case was to set BIOS to default settings. I believe your BIOS has already default settings but try to do this again.

Time Machine Won't Recognize External Hard Drive

Hi there,
My father has a 2009 iMac running Mac OS X 10.8.3. Recently, Time Machine stopped recognizing his external Maxtor OneTouch backup hard drive.
I've tried the whole litany of ideas and tips listed in this forum and other websites:
Rebooting both the desktop and the external hard drive
Changing USB ports
Checking Disk Utility (won't even display)
Can you offer any solutions? He hasn't had an issue before, so it seems to be an isolated incident. This desktop is for his business, so it's very important for the files to be backed up.
Thanks.
Update: After submitting this, I received a dialogue box that said the computer cannot read the external hard drive.

If the drive has more than one interface (USB, FireWire, Thunderbolt, eSATA), try one of the other interfaces.
Check that the data cable is securely inserted at both ends.
Try a different cable.
If you're connecting the drive through a hub, connect it directly to a built-in port on the Mac.
If you're connecting it directly, try a different port.
Disconnect all other devices on the bus, or as many as possible.
Test the drive with another Mac. Test another drive with this Mac.
If the drive is bus-powered, but has an AC adapter, connect the adapter.
Boot into Recovery and launch Disk Utility. Is the drive recognized?
Start up in Safe Mode and test.
Reset the System Management Controller
If the drive doesn't work under any of the above conditions, and if another drive does work with the same Mac, then the drive has failed. You may be able to salvage the mechanism by removing it from the enclosure and installing it in another one, or in a drive dock.

Macbook Won't Recognize Internal Hard Drive

When my Macbook starts up I either get a grey screen or a flashing folder with question mark. It will not recognize the internal hard drive. After researching, I'ved tried everything out there. Opening in safe mode, reseting NVRAM, booting from Lion install USB flash drive. The internal hard drive just will not show up anywhere, even in disk utility. Answers I've found:
1. A key is stuck pressed down
Slap the keyboard a bit to dislogde any keys
2. Test Internal HD
Test by taking to genius bar and they will test HD for you
or test yourself by getting SATA cable to USB and connect to another Macbook. (Make sure you get the right cable, mine is SATA3 to USB 2.0).
3. If Internal HD is Dead
Buy new Internal HD (Solid State or SATA) - Crucial seems to be the best website. Note, you'll most likely have to do a fresh install of your operating system.
Installation tutorials are online, it's really easy.
4. If internal hard drive is not dead, then it could be a bad SATA cable.
I recomend getting someone else to replace this although there are tutorials online.
5. Top Case may need replacing (see #1) Not very likely, but very easy to do yourself, you can find them online around $120
I'll have an update tomorrow. Oh, and a screw is also stripped so it may take awhile to get out.
My specs: Macbook 2.16Ghz Part No.MB158LL/A (Black)

When a hard drive fails to appear in Disk Utility that usually means the drive has failed. I really don't understand the purpose of the rest of your post. I don't even know what the question is, but I'm guessing you want to know if the drive should be replaced. The answer would be, "Yes."

IMovie Won't Recognize External Hard Drive...?

Hello,
Yesterday, I upgraded to a new Macbook Pro using OSX 10.9.4 (Mavericks) and I'm working with iMovie 10.0.2.
On my old Macbook, I had an external hard drive which held all of my raw video footage, and instead of filling my hard drive with iMovie Projects and videos, I just kept them saved on the hard drive and edited projects from that.
Theoretically, this should be possible with this newest version of iMovie, right? However, when I open iMovie, I cannot find the hard drive. It is connected to my computer, and I can see and access it on the desktop, but there is no "Devices" icon listed in iMovie. Isn't it supposed to automatically display? I have two external hard drives, both formatted as Mac OS Extended (Journaled), and I tried both of them, but why don't they display in iMovie?
Is this a strange problem or am I just completely missing something really basic........? I've looked online, and it seems like they should display automatically.
I'm stumped and am totally unfamiliar with this version of iMovie.
Thanks so much for your help!

It might be really basic, but what was the solution? It eludes me....
== ==
Okay, quick edit, the answer is to double click on the .imovielibrary file you want to import. I still think that is not obvious, you'd think there was something you could do inside iMovie that would work, or, that it should simply recognize it automatically...

G5 won't recognize external hard drive

I own two iMac G5's using Tiger OS X 10.4.11. One (iMac #1) refused to recognize outside info but everything else worked fine. I replaced the PRAM battery, reset the PRAM and it went on-line (DSL) without a problem. But it still will not recognize my LaCie hard drive with the clones on it. The other G5 recognizes the same hard drive and will do a clone. What could be the problem with iMac #1 with the new PRAM battery as it always did recognize the LaCie? I do have the original install DVD to iMac #1 and use the disk utility on it at times.

Have you tried using another peripheral and connecting it to Mac #1 to make sure the ports are functioning properly?

Suddenly won't recognize external hard drive

Hi,
Yesterday, while my 3- or 4-year-old external hard drive was plugged into my MacBook Pro but not being actively used by me, I heard a faint "click" come from the external drive. Since I was done with it, I tried to drag the icon to the trash to eject it, but the icon turned a faded grey color, and a message popped up saying something like "The disk was not ejected properly, etc."
Now when I turn the external drive on, I can hear it starting up and the lights come on as always...but the icon won't show up on my desktop.
I can find the external drive in Disk Utility, but that's it. I clicked "Repair Disk" and "Verify Disk", but the icon still won't show up on the desktop.
My buddy tried connecting it to his PC laptop, and the same thing happened -- his computer knew it was there, but he couldn't open it and actually USE it.
-It's not the power supply, because it turns on.
-It's not my laptop's USB slots, because both of them detect other devices.
-It's not the USB cable itself, because the computer detects the hard drive via the cable.
-I opened up the enclosure, which is made by a brand name called "Anvesome" or something (The icon itself is called Afterthemac, and the sticker inside the case says Western Digital, and it was manufactured in 2005. The hard drive came in a box with less-than-perfect English grammar, if that means anything.
I had been using this external drive on my eMac for a few years, and about 7 months on my MacBook Pro with no problems. If anyone knows what's wrong with it, or how I can recover the data, that'd be great!
Thanks!
-Andrew

The enclosure should come with its own set of instructions. One end of the hard drive will have some pins, and it will just plug into a cable or connector. I personally like OWC enclosures, and here is a link for installation instructions for their external enclosures:
http://eshop.macsales.com/tech_center/basictrob.cfm
Not knowing exactly which drive you have, I can't make a specific recommendation. I'm guessing that it may be a 3.5 inch SATA drive if it was bought to be used with an eMac, but you would probably have to find out for sure from the serial number. However, if you look at a set of installation instructions, you should be able to gain some insight as to how to remove the drive from its current enclosure.
You may also want to check with Western Digital, as they do have a link to some data recovery services should you ultimately need them:
http://support.wdc.com/recovery/index.asp?lang=en&selregion=americas
However, professional data recovery can be very expensive, and if you can place the drive in a different enclosure and use one of the links eww gave you, you may be able to recover your data for a fraction of the cost.
Go ahead and get your new 2 TB drive and get your stuff backed up. I don't think it would hurt to let the old drive sit until you figure out what you want to do with it, as long as you don't let it sit for years and years.
At this point, we don't really know if the drive has physical damage or not. If not, data recovery costs shouldn't be too bad. If the drive actually has failed, then expect to pay a lot.
Good luck!

AirPort Extreme (MC340AM/A) won't recognize USB hard drive

Hi,
It was working fine (at least that's what I believe) to one point, and then all of a sudden, AirPort utility won't recognize my external HD connected to USB port of my AirPort.
Just to eliminate possible confusion... drive is formatted as Mac OS Extended (Journaled) and I had another one as well, sitting on my desk that's formatted as FAT32. Both of these drives were connecting fine to AirPort utility till last night. All of a sudden, absolutely nothing happens when I connect either one of these two and turn it on. AirPort Utility/Disks pane shows: NO DISKS FOUND.
I even replaced this USB cable just to eliminate this possibility, still nothing.
Could it be that my USB port just died? I have 14 days to return it and I'm on my second day, so I want to know before I run out of my return bonus.
Thanks in advance!

OK, I just tried another external HD. This time it was LaCie 1Tb. As soon as I connected it, it was recognized by AirPort Extreme. What's puzzling is, that same thing happened with my SimpleTech 1Tb one last night. It was easily recognized by AE and then all of a sudden AE would never recognize it again.
At first, I though maybe these HDs are not supported by AE, but that's not the case. One is LaCie with Samsung HD103UJ drive inside purchased at Apple store, another one SimpleTech with WD inside, and other two are both super reliable Sygate HDs (never ever had any problems with them).
Hmm... I just disconnected LaCie one and tried SimpleTech one more time and it worked. AE can see it again. What's going on in here? Something is definitely not right.
Can't test this port through printer since I don't have one available at the moment.

LR 4 wont recognize 2nd hard drive in the source during import??

I run 2 hard drives in my PC. One drive is for programs only. The second and larger is for photos/music. When I go to import the source pane ont he left will not recognize the B: drive, Only the C: drive and it will even recognize my M: drive with is my external. Im not sure what to do at this point to add the B: drive to the souce. Thank you

Sometimes it helps if you put one "dummy" picture on a drive via Win Explorer. So, try this first and see if your drive shows up.
If this doesn't help:
Letter B is not a good choice for a drive on a PC. This is because of ol-old times when drive letters A and B were reserved for the 6.25" disk (A) and floppy drive (B).
That's why the first drive in today's PCs is still named (lettered) C.
And, I don't know maybe Lr does not recognize drive letters A and B. So rename your drive B to drive D.
You do this in Windows Control Panel >System and Security >Administrative Tools >Computer managaement >Disk Management. In the lower window where it shows your drives, highlight the drive in question then go >Action >All Tasks >Change Drive Letter and Path.
For more info open <Help> in your Control Panel and type <drive letter> into the search box.
