I need a new manual for my 80G dual option usb hard drive.

You can find a user manual here: http://www.freecom.com/

You will have to install the correct "Driver" for your Ethernet (Network) card. go to the link below and download what you need.

yea you got a bargain

put the sata drive in the new ps3, then offload the information onto an external discdrive through the settings menu. it is the back up option. then put the new drive back into the ps3, reconect the external drive, and go to settings, and i beleive it is called something like restore, and you can retreive the saved data from the external drive and put it on the new ps3 drive. hope that helped. please tell me if it did or not.

Go here and follow the instructions

Please rate this a fixya

1. Download this tool:

2. Format

(WARNING: After running this low level format tool,
the whole USB flash disk surface will be fully erased.
Therefore, data restoration will be impossible after using this utility!)

You can use an external hard drive with an USB hard drive case and and connect it to your USB port

Sounds like the boot record of the drive may be corrupt. When you runs the XP installation, you'll be given an option to start the Recovery Console. Go ahead and open that, should bring up a command prompt. At the prompt, type "fix mbr" (With the quotes removed). Select Yes or Continue when asked, and go through the repair process, then reboot the system and try installing Windows again.

*Note*
You might want to check first, make sure the jumpers on the hard drive are set to Master, or Cable Select, and make sure the drive is connected as Drive 0 on the Primary IDE channel.

Hope this helps!

This is mostly a power issue, but if you use a hub it may be latency as well. Some USB ports limit power to 400-500ma per port, the Passport Essential needs a bit more than 1000ma and won't work at all with these computers. Other USB ports/hubs limit the total power available for all devices combined... this is why, in your case, you can use one drive, but not both.

FYI, higher speed devices also tend to need shorter cables due to latency. (Light & electricity travels about 1 foot, or 30 cm, in a billionth of a second; this limits the size of high speed devices. In layman's terms, latency is the Brontosaurus effect, since the head takes a while to talk to the tail.)

To boost power, Western Digital recommends using a 22" USB 2.0 Power Booster Cable (WDCA029RNN) to combine the power of two USB ports into the one Passport Essential USB port--it is also a bit longer than the original 18 inch cable. For all EXCEPT the black Passport Essential drive, you may also the WD Passport™ Power Supply Adapter (WDPS021 for the US voltage version). See Western Digital knowledge base ID 1296 for more on this issue.

Hope this helps!

A quick thing to try Is
remove the 80gb from ide cable and power plug and set the 20gb back as master.
boot into windows from 20gb 1 time ,
then shut down hook the 20gb as a slave and the 80 back up as master
Allow windows to find new hardware , "watch closely down by clock ". It will tell you when windows has finished and will say you might need to reboot before new hardware will work properly
After rebooting Both should show inside My computer
Good Luck I hope this helps
