Power Mac G5 :: USB2 Card Becomes Unresponsive?

Nov 28, 2007

I have a USB2 PCI card in my G4, and any devices plugged into it (mainly my iPod Shuffle) become unresponsive after a few minutes. For instance, I will be copying songs to my iPod, and halfway through, the copying process will drag to a halt. Burning CDs to a USB2 CD-RW often fail because the burn cannot complete. I have tried two different brands of USB2 cards with the same result.

Information:
PowerMac G4 350 MHz AGP
Mac OS X (10.3.9)

PowerPC :: External USB2.0 Drive Won't Eject From G5?

Aug 12, 2007

Anyone have suggestions? I have a single 1.8ghz g5, 1gb ram, 10.4.10. I have a maxtor OneTouch III USB 2.0 200gb drive attached to it.

I can not seem to eject/unmount this drive. Every time i hook it up I just have to end up pulling the USB plug or turning the drive off suddenly to get it to "eject" but then i get the improper device removal error/warning message.

I have tried dragging to trash, I have tried apple E (which is what I usually do to any device) and I have tried going into disk utility and ejecting/unmounting from there as well. no dice.

OS X :: Firewire 800 External Drive Is Slower Than USB2.0?

Feb 5, 2010

I recently bought a VANTEC NexStar 3 NST-360FBSU-BK. In the exclosure, I have a SATA drive capable of 3.0Gb/second. It's attached to my Late 2009 Mac Mini via FireWire 800. Based upon my understanding and in this situation, the FireWire should be the bottleneck. Therefore, I should be enjoying bandwidth somewhere shy of 800Mb/second. nfortunately, I'm not getting any where near that speed. I can transfer a 726MB file in 18.6 seconds. According to my math, that's ~5808Mb/18.6 seconds = ~312 Mb/second. This is not even FireWire 400 or USB 2.0 speed.For completeness sake, I also just upgraded from 2GB of ram to 4GB (both PC8500) but nothing seems negatively affected (in fact the computer is much, much more snappy!).

MacBook Pro :: USB Ports Will Only Recognise USB2 Devices?

Apr 26, 2012

This is a weird one.. My USB ports will only recognise USB2 devices now and only if they are powered (my back up drive for instance). I've talked to Apple who believe it's the motherboard but shouldn't the ports have failed completely if that's so? Machine is a Macbook Pro 15" Intel Core i5  2.4 GHz running Snow Leopard (tried Lion but lost too many good apps under that system). Also if I unmount my external back up drive, it's not recognised again unless I restart or interrupt power to the external USB 2 drive. Almost like the old serial devices!

Did a total erase and reinstall of Snow Leopard 10.6.8, tried a powered hub and Apple had me do all the usual key combo resets all to no avail so it looks like I'm going to need a muthaboard. It just nags me that it still sees USB 2 only. How can it fail just a bit and then stay that way??

Info:
MacBook Pro (15-inch Mid 2010), Mac OS X (10.6.8)

Hardware :: Possible To Just Run The Mini Off The External Drive Via Firewire Or USB2

Jun 5, 2009

I have the 2007 intel mini and I am looking for hard drive options. Was thinking of installing a 320 gig 7200 drive in it but they are about the same price point as an external 1 TB 7200 3.5 drive. Is it possible to just run the mini off the external drive via firewire or USB2? Would that be slower than using the internal drive?

Mac Pro :: External Hard Disk No Longer Operates At USB2 Speeds?

May 6, 2012

I have an external Lacie 1 TB hard disk which used to operate at USB2 speeds, but ever since I upgraded to my my Intel Mac Pro (from a G5) it only operates at USB1 speeds regardless of which USB port I plug it into. When I open up System Profiler, it reports "speed up to 12 Mb/sec" which of course is only USB1.1. It used to show "speed up to 480 Mb/sec". Do I need to reformat it something?  Can I force it to connect at USB2 speeds?

Mac Pro, Mac OS X (10.6.8), 2 x 2.66 Dual Core

Mac Mini :: Unable To Burn DMG Files To CDs On External USB2 Disc Burners?

Jul 5, 2012

I am having difficulties burning 88.x MB DMG files to CDs (new CD-Rs and an old CD-RW) onto two different external USB2 disc burner drives (both have power AC connected: HP and LG Super brands). The new Mac Mini (no disc slot drive)'s updated 64-bit Mac OS X 10.7.4's Disk Utilities tries to burn and then fail right away or after a few seconds. The error says "Unable to burn 'whatever.dmg' (The disc drive did not respond properly and can't recover or retry." Nothing interesting in dmesg, but Disk Utility's logs had details:[URL]. 

I do see my drives' lights on during the burn. I can quick erase the old CD-RW fine. I can burn 538 MB from an 64-bit Windows 8 on my Acer AM3800 PC with the same discs and external burner drives without any problems. Also, I thought it was my USB cable extension, but it wasn't it. I don't use any USB hubs either. DMG files are fine too. I did notice copying from a CD to Mac Mini's local HDD was slow, but no failures.

PowerPC :: PowerBook G4 Will Not Reboot

Jul 10, 2008

I recently restarted my computer and it will not re-boot. Up to that point before I restarted I had no problems with my laptop or did the laptop show any signs of a problem beginning or persisting on my comp. When I am booting up OS X I get to the Grey screen where I normally get to before the system fully boots up. That's where I get stuck, all i get is the thing spinning around under the apple logo ( not the color pinwheel) and it just sits there forever. I hear the quiet sound of the fan blowing or what ever it is and a click here or there from the hard drive maybe trying to boot up.

Windows On Mac :: Reboot Into OS From Bootcamp?

Jun 20, 2009

I setup a bootcamp partition on my macbook pro, and tonight I had a weird issue happen. Now first off let me say that I am running custom video drivers instead of the supplied bootcamp ones (figured I would say that now, just in case).

I was in vista for a while playing kotor, and I finished up and right clicked on the bootcamp icon and rebooted into Mac OS. The screen went blank, but the laptop stayed on. I didn't hear the system bong either, just stayed blank screen, keyboard lit up. I finally had to press and hold the power button, and start it back up. Then it started up fine.

When I went back into Mac OS, I noticed the clock was messed up and had the wrong time. When I unchecked maintain the time it setup perfectly.

I don't know if something may be wrong, or if this kind of thing is normal. Should I perhaps take it back to apple? Or am I just being overly paranoid.
