@Jermofoot:
Is this USB?
Are you using it with the same system you used to?
Could be a lot of things. Sounds more like a power issue. Try a different USB port, or USB cable. I’ve had systems that would not operate USB peripherals from the front ports but would from the back. If you have other USB items that are working fine, try using that port. Potentially could be a driver issue. Try another computer as well. We want to eliminate the possibility that it is the driver, port, cable, HD that has the issue.
You could also open the case and try to mount it internally and see if that changes anything.
Same system (laptop) as previously used on and the USB ports are good at the PC as other USB devices (wireless mouse, flash drives) are working in them. This does not rule out the USB cable as bad and I have one I can borrow for the weekend so I’ll try that too.
The external drive has an AC adaptor so I don’t think power is the issue.
I did not try plugging it into another computer.
I could not find this – http://www.seagate.com/www/en-us/support/downloads/seatools – last night having come upon this at more or less bedtime so I was a bit done. I was going to re-format the drive to FAT32 overnight so I could do the backup of the PS3 tonight and the drive swap tomorrow morning.
I’m hoping it is some sort of software issue with the drive and not a mechanical failure. I’ll try the Seagate programs and see what happens.
I’m not out any data for losing the drive just the hardware but having it would have allowed me to put off getting an additional drive for a bit of time yet.
