PowerPC :: No External Drives Recognized?

Aug 1, 2010

My G5 PowerPC will not recognize any external drive, on the desktop or Disk Utility. One showed up briefly, but the computer locked up . I've tried each drive on my Imac and they all show up and work perfectly.

PowerPC :: External Hard Drive Not Recognized By Computer

Sep 19, 2010

My WD firewire 800 drive has stopped working, I can hear it spinning when I plug it in but the light doesn't come on and my computer doesn't recognize it. I've tried both the firewire and usb connections.

PowerPC :: Hard To Read / Write To External Drives With G5

Sep 17, 2007

This issue has been killing my work flow for quite awhile. I have a G5 dual 2.0. I can barely read or write files to an external hard drive. Say I try and copy 1.56GB of audio (12 files) from my external drive it will start to copy then stop at 500mb for minutes then start moving as normal and stop again around 900 for minutes.. then again at 1.4. This also happens when writing.

Here is the confusing part. This happens with two external drives (different models) with firewire 400, 800 and USB. I have reinstall OSx. I have repaired permissions and ran repair disc on everything. These hard drives work FLAWLESS with my Macbook Pro as well. Gr what can this be? It takes forever to copy data to or from a drive which is often how I transfer audio between my desktop and laptop. I should soon have Mac Pro money and this crappy G5 can go out the window. I am on 10.4..

OS X :: USB Drives Not Recognized / Mounting?

May 25, 2009

This just started happening within the past month or so. None of my USB drives are being recognized or mounted. They appear within Disk Utilities and I can verify and run checks on them, but they do not mount. This isn't limited to one device or any specific port. It happens with USB memory sticks, external Maxtor drives (two different ones) and now my Canon PowerShot camera. Basically anything the Mac would mount as an external drive has this issue, so I know it's not specific to any hardware.

I do have a work around that I found on [URL] -- If I reboot with the device plugged in and hold the 'command' key the drive gets mounted. Next time I try the device though (in the case of my camera plugging it into another computer) it's not recognized again. I basically have to do this reboot procedure any time I want to use any device.

MacBook Pro :: Old And New Hard Drives Not Recognized?

Aug 4, 2010

Last week, my Macbook Pro (13", Mid-2009 model) froze. I held the power button to shut it down, and when I tried to start it back up, it gave me the blinking folder of death. I tried to boot using my Snow Leopard disk to try and repair the disk, but there was no drive except my DVD drive found.

So, I brought it into a local Apple store, and the "geniuses" told me my hard drive had failed and that they could replace it for $300 (I'm 1 month out of warranty, no AppleCare). I declined the offer and bought myself a hard drive off NewEgg for $50 (Western Digital Scorpio Blue 500GB).

I opened the computer up, took out the old hd and put in the new one. I booted to my Snow Leopard disk to install it, and again there was no hard drive found. I tried to go through Disk Utility as well and there was no listed hd.

Software :: USB Flash Drives Not Recognized

Aug 8, 2009

I have a 2008 (2/2008) 24" aluminum imac that is not recognizing certain USB flash drives now. The drive (Sony 8gb) worked before but does not now. When started up with the drive in a USB port, system profiler will find it but disk utilities will not (nor does it appear on my desktop). I have tried all other USB ports in this computer with no results. This drive still works fine on all other macs in the house. This problem is isolated only to flash drives since all other USB accessories still function fine. I recently added a Sandisk imagemate all-in-one card reader to this system and suspect that this might have caused the problem since oddly enough, my Sandisk flash drive still works fine. The only driver I installed with this reader was the application start up button (to launch iphoto).

Mac Pro :: Upgraded To OSX Lion 10.7.4 & Optical Drives Are No Longer Recognized

May 24, 2012

I have a MacPro 1,1 with a 2 x 2.66GHz Dual-Core Intel Xeon and I just upgraded to OSX Lion 10.7.4. Upon upgrading my system stopped recognizing the two optical drives I had installed. Is there a patch or are there drivers that I can download to fix this? Has this happened to anyone else? I was prepared to lose access to some older software but not my optical drives!!!  

When I do a "system report" through "About this mac" both of the drives are listed but they dont show up on my deskop. I have an Optiarc DVD RW AD-7170A and a TSSTcorp CDDVDW SH-S202N

Info:
Mac Pro, Mac OS X (10.7.4), 2 x 2.66 GHz Dual-Core Intel Xeon

Mac Pro :: Remove Mac Raid Card From System / Drives Are Not Recognized At Boot Up

Oct 15, 2009

So I have followed a bunch of the 'MacPro with mac raid card users wanting to do bootcamp' threads. I have attempted all the hacking required but have not been successful. I heard that bootcamp 3.1 will fix this problem possibly... so in the mean time I would like to remove my SAS drives and raid card and just use the sata drives that I have to do Mac OS and Windows.

I have removed the card but when I plug the drives in and boot up the machine, the drives are not recognized. Is there some plug that I need to reconnect somewheres?

PowerPC :: New PowerBook G4 RAM Not Being Recognized?

Sep 7, 2006

This is ridiculous. After I went out and got a new screwdriver to install my 1GB stick of RAM, which I got off of Newegg, it is now not recognized by my computer. So now I'm running with 256MBs of RAM. Beautiful, thank you Apple.

[URL]
This is what I ordered...Crucial Technology 1GB 200-Pin DDR SO-DIMM DDR 333 (PC 2700) Notebook Memory - OEM

I thoroughly made sure this was the right RAM, and even people with my same type of computer have said it works on their posting thing.. 1.5 GHz PowerBook G4 15". Anyone know how I can get this to work?

PowerPC :: Blank Discs Not Recognized On G5

Apr 24, 2007

i have a powermac g5 dual 1.8 tower. the dvd burner is a pioneer dvd-rw dvr-107d. according to the system profiler, this should be able to burn either - or +R discs and cds. also, the computer belonged to a friend who was using it to burn dvds up until the day she delivered it to me.

i switched out the harddrive and reinstalled everything fresh (in case that matters.)

now when i put in a blank dvd or cd (different brands, different formats) it comes up with an error message that says: This disc cannot be used because it is not recognized.

PowerPC :: Audio CD Recognized But Not Played

Jun 30, 2007

I own a PowerMac G5 but for my anniversary my girlfriend got me a G4 Cube because she knew how much I loved 'em. I just found out that you need USB speakers.

1. (Even though I don't have speakers) When I put an audio cd in the CUBE.. it recognizes it, but when I hit the play button on iTunes, the swirling beach-ball will just sit there. What's up with that?
2. Can I upgrade the processor and boost the memory up to 1GB?

G4 Cube

512MB Memory

PowerPC :: RAM No Longer Recognized By IBook

Oct 13, 2007

I hope I can get some help for a bizarre problem I'm having with my iBook G4 (1.2ghz). When I first got the machine (2004) I put in a 256mb Crucial stick and never had a problem. Recently (last 2 months?) I've noticed that a big slowdown so on a whim I checked my "About this Mac" and sure enough it only lists the stock 256mb. Is it possible for the added RAM to have just plopped out?

PowerPC :: New Internal Drive Not Recognized?

Mar 10, 2008

I recently went through the very arduous process of replacing the harddrive in my aluminum G4 12" PowerBook. The process was a complete pain in the rear, and I ended up ripping a socket off the motherboard.

PowerPC :: Hard Drive Not Recognized?

Apr 16, 2009

I have tried troubleshooting, searching this forum, & googling to no avail. I'm hoping someone smarter than me can figure this out.

Short Version:

Purchased this hard drive:

[URL]

and purchased this external enclosure:

[URL]

when I plug it into my macbook, PC, or a powerbook, the disk is not recgonized, I can not get Disk Utility to even recognize that the hard drive exists. I thought it may be a bad drive, so I sent it in to Seagate Warrenty, they sent me a new one and I'm still having the same problem. Does anyone know how I can format the drive or any way I can get it to be recognized?

Longer Version:

My powerbook crashed, so I purchased this HD to replace it. I installed the 1st seagate and when i went to install OSX and said select destination drive, there was none there to select. I was able to repair the original HD so I reinstalled it and went to install OSX and it DID show the drive to install it on, so I don't think that it is the computer/motherboard. Then I sent in for the 2nd seagate, tried getting it to work with the external enclosure and installing internally in the powerbook, etc. nothing seemed to work.

I am wanting to install the new drive in the powerbook as the old drive is on its last leg (but currently works). Every thread i have searched for that was similar, there was no solution that I could use.

Hardware :: External HD Not Recognized?

Jan 29, 2008

I am a newbie and I have searched for my answer but can't seem to locate it. I know this is probably the most asked question by newbies so I really appreciate anyone who will take the time to walk me through this!

I have a western digital external hard drive with tons of wedding images on it. I just switched from pc to mac.

I plug the drive in and nothing happens. I checked to see if it shows up in disc utility or sys profiler and it is not in either spot.

Now what?

Mac Pro :: External DVD Burner Not Recognized?

Jun 4, 2014

February 2014 Mac Pro  

Final Cut Pro X 

A DVD burner and an LG BluRay burner. 

I believe the reason why I can't seem to burn either type of disc anymore is because I have plugged them into different USB ports over the many days I've been using these devices. They work fine on other computers and were working fine on this one, but Final Cut Pro uses a "Create Disc" program that I believe gets confused by which disc drive is to be used.  

Final Cut Pro X completes the transcoding and goes to burn the DVD or BluRay disc (depending on which I selected in the Share menu) but nothing happens anymore. 

How do I flush the hardware cache (if there is one) and restart with these external devices. The Mac Pro only has 4 USB ports but I needed more so I swap out the cables from time to time as I sync iPhones or upload memory cards to iPhoto.

Info:
Mac Pro, Mac OS X (10.6.6), iPhone4 4.2.1

PowerPC :: Powerbook DVD Burner No Longer Recognized?

Jan 7, 2008

I've got a 1.5Ghz PB G4 (128MB Radeon 9700 model), and it would appear that the DVD burner is no longer being recognized. It's out of warranty. I've opened it up and verified that the cables are all connected. I know it is receiving power, because it spins up when I tell the computer to shut down. Symptoms: disc in the drive does not mount, eject key does nothing, Disc Burning in System Profiler says "No burning device was found. If you are using an external device please make sure that it is connected and powered properly.", disc in drive is not seen by Disk Utility, ATA in System Profiler only shows my hard drive.

PowerPC :: IBook G3 Firewire Device Not Recognized?

Jun 19, 2008

I'm attempting to upgrade a family member 800mhz iBook G3 from 10.2 to 10.4 using my old iPod as the install drive. (Restored a DMG, etc) Only problem is that (other than being an ancient computer, I guess) is that said iBook doesn't see the iPod until after OSX loads (white spinny guy).

Tried holding Alt at bootup (not listed), setting it as the default boot device (just skips it and goes right to the HD), and just running it from OSX (reboots, straight back to OSX desktop).

Is there something I'm missing? Does this model G3 not allow detecting boot devices at start up? I'm kind of at a brick wall here. Should I just bite the bullet and do a target disk install?

Hardware :: USB External Drive Not Recognized

Dec 27, 2006

I'm having some troubles with an external enclosure and my sister's new imac. The enclosure I'm using is a Tao Tec 2500 (2.5" drive) IDE --> USB device with the Y-cable. The drive has been formatted to NTFS and has some files on it. As far as I can tell though the version of OSX the new imac is running should support read capability with the file system though. The computer is a latest generation imac (purchased about 12/20/2006) and running a new revision of OSX (about 1.0.4.7 I believe). My problem seems to be the computer simply does not recognize the drive. Disk utility doesn't see it nor the usb manager in system tools. The LED indicator on the drive indicates that it's receiving power and I've tried swapping the usb ports around just to be sure I don't have a bumed port. It simply seems like OSX just doesn't know the drive's there.

PowerPC :: EMac Airport Extreme Card Not Recognized

Dec 22, 2009

I just installed the Airport extreme wireless card on my emac, but I have run into some problems:

1)after installing the card, the mac took a very long time to start up, I tested to make sure it was the card: everytime I started it up without the card, it did the normal thing, but with the card, it took a long time

2)after finally starting up, nowhere can i find where/how to configure the wireless. When I go to configure the network, it has all options, but the airport card option is not usable.

So: how can i access the airport card settings to get wireless connectivity?

Power Mac G5 :: External Hard Drive Not Recognized

Oct 9, 2007

I am a photographer. I use 4 X 1TB LaCie external hard drives to store my digital images. 2 as masters for different business segments and 2 as their back-ups. They are daisy-chained using Firewire 800. Recently my G5 has stopped recognizing one of the drives. Is there any way to get my machine to re-recognize the missing drive? I have rewired the four drives to see if there was a problem with the cabling, but this does not appear to be the case. I am coming up to the 1 year warranty period on this drive and need to get it back to LaCie if there is no other solution.

Hardware :: Iomega Desktop/External HD Not Recognized?

Dec 15, 2007

This may a well beaten subject, but I must get an answer.

I have used an Iomega External HD (black series/800/firewire) for about 6 months, using it to load up with important files.

Now all of a sudden, it does get recognized by either my Mac G5 (OS X 10.4) or my MacBook Pro. In fact, I get the Disk Insertion (initialize/ignore/eject) window.

Why initialize, that will only wipe out all of my files on the HD.
