It happens a lot of time that data gets deleted from the system and in the worst case it will even remove from the trash. I have faced this situation a lot of time, so in spite of loosing the data I found out the solution to it.
Firstly lets see what happens once we delete the data from the system. When ever we delete the data it does not get deleted but the data is moved from the directory and stored else where that's the reason we are not able to locate the data on the current location we have deleted data from.
The different location where the data gets stored is different for every operating system, like if you are a Mac user it gets stored in Trash, If you are Windows user it gets stored in the Recycle bin and if you are a Linux user than the data gets stored in the KDE that's the waste bin. So the first step should be to look, for these places once you've deleted the data.
As I've talked about the worst case scenario that means you deleted the data from the waste bin too then also the data is not deleted. The data then also is recoverable. The data remains in the system till the time the data is not made available for another set of data to get stored in the system. So there is no need to worry about the data just the right steps to follow to get the data back.
The data can be recovered from the system. The operating system not right away allocates the free space to the other data, you can undelete the data for a considerable amount of time. The case in which the data recovery is next to impossible is if you have recently de-fragmented the hard drive. What happens in this case is all the free space is being utilized or defragmented so the free space made recently is made available for the data to get stored.
Another situation when there are chances of the data not getting recovered is, if the hard drive is full in this case also as the free space is not available, so as soon as the operating system finds the free space it allocates it to the new data and your deleted data gets overwritten.
For situation like these when the data recovery is next to impossible Mac data recovery software is there and these software claim the recovery of the data. The process is quite simple just in five steps the data will be recovered.
In the next window you will find several media/sections from which the software supports recovery. From those sections you need to choose Recover Hard Drive.It will take us to another window which will ask for another set of selections as you are in search of mac data recovery from trash you need to choose Deleted File Recovery
Finally the list for the hard drives will display so choose the drive from for which you want the recovery to be done, and upon selecting one press next.
Once done with this it will show the list of all the file s deleted from the hard drive select the file you want to recover and save it to the specified safe location
