It could be that it's formatted with an HFS+ filesystem, which is not natively recognized in windows. Open up the disk management and check the filesystem on the device. If it is HFS+, you can get it to be recognized by getting all the data off, formatting it with another filesystem (FAT32 or NTFS are recommended), then putting the data back on.
Here are some options to try:
- Purchase an alternate enclosure for your hard disk enclosure in case the circuit board in the WD case has gone bad.
- Try accessing the drive via MS DOS window and use CHKDSK command to repair the drive (if you can get it to be recognized).
- Try connecting the drive to an alternate PC or even a Mac to see if the drive can be recognized (perform disk repair if recognized).
The Western Digital Scorpio Blue 500GB hard drive is formatted for PC, not Mac. The simplest way to get your MacBook to recognize this new drive--and therefore copy the files from your old drive--is to plug it in to a PC and format the drive. I was advised to format with FAT 16, as this would be recognized by my MacBook. Fortunately, the process was not that involved, since the Vista-driven PC found the drivers for the WD Scorpio Blue automatically. Once formatted, I safely removed the drive and plugged it into my MacBook via a USB port using a BYTECC Drive Mate. Magically, it now appeared on my MacBook Desktop and was recognized by the cloning software I was using, SuperDuper. Three hours later, the files on my old hard drive were successfully cloned onto the Scorpio Blue--except now I had an additional 364GB of storage space. Swapping out the old drive and replacing it with the new was not a big deal at all--just make sure you have the right screwdriver for the last task--a Torx #6. Mission accomplished.
I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)
A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.
1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability
2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)
3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.
4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.
5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port
If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further
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.
load the driver for mac use, the external hard drive comes with cd, the mac driver should be inside, load it to your mac computer. if you donot have the cd go online to western digital and download it. just load the driver and u will be fine, make sure u connect the cable in right places.
