I have a WD external hard drive USB 2.0 750 GB. It was working just fine for many months, and suddenly, my laptop won't "read" it -- it's not listed/detected in "my computer." I thought there was something...


If the device is recognized and not listed as a driver in the Explorer, then the disk is not recognized as having been partitioned and formatted. You can use the Disk Manager to see if there is anything listed on the disk.
Start - > right-click My Computer -> Properties
In the management console, go to disk management and check your disks. The external disk should be there and then you can see the partitions and drives assigned to it.
If there is nothing on it, your MBR could be damaged, which needs to be restored.

Alternatively you could partition and format it, but then you'd loose the data on it, so that is a last resort.

I think a program called Acronis Disk Director Suite can restore MBR's. Have a look at this external hard disk troubleshooting article.
