A few days ago I purchased a Lexar 16Gb UDMA card. I put the card into my Canon Pro Camera and selected 'Format'. All seemed to go OK & I used the card for just over 1Gb of loading....

I was about to 'Format' it again in the camera and noticed it was showing as a 8Gb not 16Gb. I checked it in the computer with the File Explorer --> Properties & it reported 8Gb also.

At first I thought I had been ripped off with a forgery but when I checked it under 'Control Panel --> | -->Disk Management the card showed up as 16Gb with two partitions of 8Gb each. One partition was 'Active & healthy' but the other partition was 'Unallocated'

I was unable to delete a partition, expand a partition etc (the commands were greyed out).

Can anyone advise how I can restore the card to one partition of 16Gb please. Will it have to be done in DOS?
