Have had this drive for years and it worked perfectly, always detectable. All of a sudden it is undetectable on three different computers. Changing the cord does not help. Light comes on in drive when connected. I get no message that computer cannot access the drive. Any ideas before I spend a small fortune to recover the data.
I recommend you try running a diagnostic on the drive using WD DLG to determine its health.
If the drive is still not seen on the computer but it is seen in Disk Management then it may be possible to still extract the data utilizing data recovery software. There are several kinds of Data Recovery software available. If you do a web search for Data Recovery it will yield plenty of data recovery software options.
