How can I recover my data from an unallocated hard disk

Situation: I have a 1TB external hard disk which was partitioned to 3 partitions.

Without knowing what happened, one of my partitions got lost and became unallocated.

All my precious photos are saved on that drive (I’m a photography lover), so please tell

me how can I recover my data from an unallocated hard disk space. I have googled

and was told to use data recovery programs. Nevertheless, recovery apps I found on the

internet are expensive or just allow me to recover limited files, so I desperately want to

know whether there is a free or relatively economical solution.

Solution: since the original partition becomes unallocated, we can say it has been lost. To

recover data from lost partition, actually, users do not need to turn to data recovery

software most of the time. Nowadays, there is free partitioning tool which can help recover

lost partition from unallocated space. After partition recovery, original data can be

accessible again as long as they are not overwritten. Note: any write-in operation may

make lost data overwritten, so users had better stop operations as many as possible once

an existing partition gets unallocated.

Well then, which free partition program should we employ to recover data from an

unallocated hard disk space? Here, MiniTool Partition Wizard is highly recommended. It is

easy to use and provides mighty data protections. Detailed steps are as follows.

unallocated hard disk space, we can choose unallocated space to scan.

Step 4: check all needed partitions (both existing partitions and lost partitions should be

included) and click "Finish".

Letter". Then, to recover data from an unallocated hard disk space is completed.
