USB hard drive not recognized by Mac and by PC

I am using a WD 320GB MyBook external USB hard drive with a MacBook pro (Leopard and - via Parallels - Windows XP Professional). I keep a large picture archive on that external drive, using it for about 6 months from both sides, Mac and PC. Suddenly it doesn't show up on either the Mac not the PC: has power, starts running but seems not to be recognized. What can I do to recover my files?Desperate - Marion

Does the external drive work when connected to some _other_ computer? (Friend? Office? Home?)

It could be a failure either in the "hardware" inside the external-case (the USB adapter & interface)
or in the disk-drive "inside" the external-case.

So, a qualified technician can open the external drive, remove the disk-drive, and connect it directly to a computer, to see if the files can be "directly" read from the disk-drive.

If not, then you should search online for a "data recovery" service -- they are expensive, but they physically repair a damaged disk-drive, just long-enough to copy your data to another disk-drive.

My macbook pro running leopard 10.5.8 will not recognise my hitachi 320gb external hard drive


Find the drive and make sure it is formatted as a FAT32 drive. Mac computers only recognize drives in that format. If it can't be seen at all, try plugging it into a PC and then formatting it as FAT32. It should then be recognized by a Mac computer.

I am using SuperDuper to clone my 160GB MacBook Hard Drive to a 500GB Western Digital Scorpio Blue. My problem is that I cannot determine why neither the SuperDuper program nor the MacBook itself...


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.

Hard Drive not mounting


Check the jumper on each hard-drive.

My guess is that the WD drive has the jumper in the "correct" position, for mounting inside an external case, while the other drives have their jumper set to an "incorrect" position.

Set the jumper to MA(ster), not to SL(ave), nor to C(able)S(elect).

Formatted (on PC) 1TB WD hard drive cannot be altered on Macbook


What OS are you running? What is it formatted as FAT32 or NTFS and how big are the partitions. Various operating systems, hardware and formatting schemes have different limitations. If you want to use the drive in Leopard formatted with NTFS which is the only way to create partitions larger than 20 or 30 GB you may need to install an NTFS file system driver like FUSE.
The other option is to format it as HFS and install Macdrive 7 in Windows to use Mac formatted drives in Windows.

Hope this helps.

Hi-

Chances are these large memory hard drive should be plugin with a USB and adapter of its own since 320Gb is too big and needs power to be able to recognize. But if you find it defective you have a year warranty from the manufacturer, you can call them up for a replacement.

Hope this help. Thanks for using Fixya!

WD MyBook 320 GB Premium - Retrieving Data


You should buy a program called "Partition Table Doctor". I went through the EXACT same thing and it was just a bad partition on my mybook which is the EXACT same as yours is. It cleared up the problem for me. I still have problems with my mybook so i wish that I bought a different hard drive, but oh well.

but try "Partition Table Doctor", it will scan your mybook and fix any partition errors with it.

I was in the same boat as you over a year ago and trust me, "Partition Table Doctor" is a LIFESAVER!
