Having had hair-pulling troubles with every brand of "name-brand" external drive that goes on sale every weekend, I now buy external drives only from Other World Computing. (US$100-150): Dump the flaky WD enclosure entirely and get a known good external unit. It has it own dedicated power supply (power "brick") and thus provides power the computer cannot (example: Sabrent HB-MC7B Premium 7-port Aluminum USB 3.0 Hub. It gets power from two USB ports that can help.ģ) Medium cost (under about US$40): Get a POWERED USB hub. Get a "Y" USB cable (example: 1.0 Meter (39") USB 2.0 A to USB 2.0 Mini B 5-Pin Cable - Auxiliary USB "Y" Power Design ).

There is strong evidence in reports here that dumping the Windows formatting helps with the drive being recognized reliably.Ģ) Low cost: (under US$10) if you have two free USB ports. Disk Utility will make it look just like your computer sees its internal drive. The drives come formatted for Windows or, if a "Mac Edition," often have an odd proprietary WD formatting scheme. Use Disk Utility to erase and reformat the drive as Macintosh Extended (HFS+) Journaled. There are four possible actions that can help ranging from free to expensive:ġ) Free (if you do not need to share the drive with a Windows computer, and have a way to back up date already on the drive). Sometimes with age the drive starts to demand more power than the computer can supply.

They have to get all their power from the computer's USB ports.

Passport drives show up in a lot of problems reports here, as do many "bus-powered" USB drives.
