Question about Computers & Internet
Hi! Just bought 320GB My Passport Hard Drive and it won't work on my mac. Can you please help? Do I need to download anything? I have just copied pics from a PC so I can transfer them to my mac....and it won't work! Thanks Cxx
This could be a formatting issue, a power issue, or, if you use a hub, it may be a latency issue as well.
Mac's, in general, do not recognize NTFS formatted hard drives. Check the drive properties to see how it is formatted. If this is the case, you can try to reformat the drive as FAT32 (using the MAC) and start over. Keep in mind that you may run into partition size limitations, depending on how current your computers are set up.
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!

Tips for a great answer:
Can't you just delete the posts you dragged? You can always format the drive and start over again. You can find some guidelines in the link below.
http://support.apple.com/kb/HT3509 - Format external drives to Mac OS - this will delete all data on the file.
Hope this helps
