Question about Computers & Internet

2 Answers

I recently bought a 640GB drive for my G5 mac running leopard. I plugged it in, and the drive began working immediately. I ejected the drive, and then I unplugged the drive from the wall. When I plugged the power chord back in and tried to mount the drive, the power light indicator flashed slowly for a minute, and then the power light went out completely. I checked the wall outlet for power and the USB port to make sure both were in working order. Then I checked both the power chord and the USB cable to make sure they were both plugged in correctly to the wall, computer, and the drive itself, and they were all connected. Yet, I still have no power to the drive, and it will not mount.

    Yes. I have power to my entire computer. I even try unplugging another USB port that was in use by another piece of hardware to make sure I was using a working port.

    I'm not sure what program you are talking about. There was no install software required to run this hard drive on a mac. Only setup software for dealing with a PC.

    I'm not sure what you mean. There is no software required for running this hard drive on a Mac. There is only install software for setup when using it on a PC.

    Are you able to run any other USB device on your Mac using the same ports the drive was plugged into?

    If you can then the USB ports are fine, if you can't run any other device from the same USB ports that is where I would start to find the issue.

    If it turns out you can run other USB devices, do you have another hard drive you can put into the external enclosure to see if that hard drive can be mounted?

It sounds like the drive is defective. It happens if the resistors are not soldered properly and the drive gets blown out. This drive should be covered under warranty and should be RMA'ed ASAP. This is a common problem with External drives.

    sometimes too much memory can freeze it

    can you remove one of the memory and then try again

    inappropriate rating would be okay if i gave a solution or asked you to try something that had nothing to do with your problem.

    You quit conversing with me which is okay but in that case it should have been a thanks for tryin

Rev 35GB Firewire suddenly began ejecting any inserted disk after about a minute of blinking light. connected to Mac G5 - os 10.5.8 Replaced power supply about a year ago.

So any disk produces this result? You may have a bad drive, but without further explanation, it's really impossible to say.

I Have a MAC OSX 101.5 can I install leopard

Here are the minimum specs your Mac will need to run Leopard, from Apple:
  • Intel, G5, or 867MHz+ G4 processor
  • 512 megs of RAM (though if you only have 512 megs of RAM you should get some more. Trust me, I'm a pundit)
  • DVD drive (Leopard is shipping on a DVD, and your Mac needs to read it to be able to install it)
  • 9GB of free disk space (though I bet if you customize the install and leave out all those printer drivers and extra languages you can save lots of space)
Go to your apple menu, and look on the "about this mac" If your machine doesn't have the mhz's you are out of luck. If you don't have a DVD drive, you are not going to be able to install either...

Leopard OS

Is the hard drive SATA or IDE. On IDE, I know you can use delpart. Locate a SATA tool to wipe the partition of SATA drives. Install LEOPARD as usual then after rebooting.

No Power to new 640 My Book Drive

John, Ejected or unmounted may be the difference.  Have you added the drive?  If you only power it up occasionally for back-ups you would leave it off, but for everyday use once it is added you can just leave it on and after you power down then turn it off.  randy320sgi

Installing new system software on G4 imac where system removed

Well the flashing question mark means its not finding a bootable device meaning the hard drive has no OS on it. You should be able to put jaguar on it if its a retail version and not one from another mac product. Let me know how this works for you

Leopard won't install

Found this on the net:

Those upgrade cards always have given me a problem with migrating to Leopard. If you can upgrade to a used G5 or even Intel basd mac you might be more happier with less hassle.
