Despite easy accessibility of data provided by Mac however sometimes user might have to encounter some erroneous situations. Error-10000: could not unmount disk is such an error which means that you could not unmount the Mac volume. In general this error would appear during unmount the partition using disk utility. The most common cause behind this is that when same partition has been in used and at the same time trying to unmount it. Fortunately you can unmount partition, for doing so use finder icon in Dock then relaunching the option. After that unmount the volume by selecting it in disk utility and click the unmount option. However this steps required sound technical knowledge and ultimately the problem would not be resolved after unmount the volume. So eventually this is resolved through formatting the hard drive. But before you accomplish the format it is better to take the backup of data because formatting cause deletion of stored data. In the absence of updated backup third party Mac Data Recovery Software is an ultimate option for restoring the missing data effectively. To know more on that please visit at mac fixz.
