I can only comment generically:

I would try to uninstall the drive on the OS. Then re-start the computer. After the re-start, connect the drive and see if the drive re-installs itself.

If the error persists, then the drive is indicating failure. To absolutely verify if it has failed, take the drive to a store where there are MAC computers and try the drive on one of their computers to see if it works.

A continuous flashing LED on most devices where the LED does not normally continuously flash is an indication of a failure of the device. Some devices will flash an error code when designed to do so, and if possible.

Testimonial: "thanks. its a device failure. I had connected it through keyboard usb port, and it seems that the power was not flowing properly to run external memory. "

    This can be done in you "about this Mac" under the USB menu, it will show you exactly how the comp see the disk- if it's see fragment Data, the hierarchy etc... If it sees nothing, you need to isolate what is failing, the USB input or the device. So plug it in the other USB port and see if that fixes it. What you're describing sounds most like electric issues, not data issues- if stumped, replace the USB cable and see if that fixes ir

    You can always open your Disk Utility for extra help, if you find you can't get it running place the disk in a feeezer bag and put in your freezer for 24 hours. Get a new cording system and be prepared to get a couple hours tops to pull your data off. This is an old IT trick that works like a gangster!!!! Remember when you face an issue- those of us in IT use "troubleshooting theory" to knock out the easy options first!

SOURCE: My Apple G5 and WD Passport 500Gb don't mount

You need to determine whether the problem is at the disk interface or at the computer interface. Will the drive mount on ANOTHER machine using FireWire? Will your computer mount ANOTHER device using FireWire? This will tell you which machine is at fault. It's not unheard of for the FireWire channels in a Mac to just go bad, and (unless it is a Mac Pro) it typically requires a logic board replacement to address. For a G5, this would not be cost-effective. On the other hand, as I say, it could just be a bad interface in the drive itself. It's up to you to determine which it is.

I have purchased a Seagate free agent Goflex 500gb I want to run it with my Mac Pro note book it dose not work

For a MAC to use an external Hard drive, the hard drive has to be formatted FAT32 file system. That is the only file system MAC sees.

External 500gb hard drive not readable

Check the partition size in Disk Management (if running Win7 - download a free Partition Manager if not) and see if the system is seeing the partition correctly. Seagate has recovery software available on their website but you may just have to repartition and reformat.

Seagate external drive locked in "read only" ,was working fine...

This seems to happen when it's been connected to another computer. Are you running FreeAgent Sync? If so force a sync and the read only problem should go away.

I cannot copy files FROM my Western Digital 500GB

Hi,

Check the file system of your hard drive. If your PC is recognizing it, check if its a FAT or NTFS. If it is NTFS then you have to reformat it using your Mac and choose FAT. Mac OS recognizes NTFS as a read only drive. If you plan using it with your PC and MAC you should format it using your mac and choose MS-DOS in disc Utility. You cannot format the drive using your PC Computer with a FAT file system because of the capacity. Only Mac can format it with a FAT file system.

Seagate 750GB usb HDD asks to format,when opening by double click

The disk is either damaged or the USB interface is damaged.
1) You could try opening the external case and connect the disk to your computer directly (Using IDE/S-ATA cables)
2) Format the HD and use data recovery software/service.

FreeAgent Drive Manager.app does not see drive-Mac

Turned out to be an easy one!! The Seagate tech had me reinstall the drive manager, and it then worked. But he did recommend using Time Machine, which I have, over their software!
