WD 1tb portable 2.5" failure to initialise

seth.nz,

This is most unfortunate.

If the drive is spinning and shows up in Disk Management, but cannot be accessed, then the drive’s partition table is most likely damaged or corrupted. It may be possible to still extract the data utilizing data recovery software. Western Digital does not provide data recovery software. However, 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.

If all troubleshooting options and data recovery applications relevant to your drive do not result in a positive outcome, then you will need to contact a data recovery company to retrieve your data.  We have a list of recommended preferred data recovery partners that you can use for data recovery services.
