Try the website of who made the drive & see if they have a test tool, they normally contain a low level format tool that scrubs the disk overwriting everything and not just the clusters that link the data together. this will put the drive back to 'as new' with no partition information. In other words you have to FDisk it before it is recognised as a drive again.
lol what are you trying to hide??? ....... and from who? if its just from your mother lolol dont worry a format will do unless she is CIA...... otherwise it will need to be done with EE5 if I remember right it needs to be filled with 1,s and 0,s something like 35 times and wiped over and over the same method national security uses .......if your in deep dodo with the FBI hahaha you better make sure you wipe that sucker real good lol ..............
The formatted data is on the drive in layers ....... even if you formatted 3 -4 -5 times its stilll there ....... there is a way to completly delete it .......its the same method national security uses and EE5 evidence elminator I think has it and its like I said 35 times filled over and over with 1's and 0's and wiped over and over cant remember but I think its something like 35 times written and 7 or 10 wipes ......................
use a mil. spec. 7 format.. this will do all that you want will make all info.gone not even FBI/CIA can recover...the closest program avl. to your reg. user would be evi. elim. but set it to do 20 or more times!!
this will do basicly the same thing that mil.spec. 7 does but it must do it many more times!!
If you want to get rid of data on hd remove platters and then get blow torch (plasma torch better) and begin to destruct platters in circular motion. Be careful and use proper saftey precautions. This is preferred method of disk wipe. You only wipe one time (not 7) and job done! Borris out...
For the non-technical you can follow these easy steps to data deletion:
1. climb tall tree or cliff
2. throw HDD off said tree or cliff
3. climb down, don't jump remember it's onlt the HDD you want to erase
4. collect pieces and attempt reassembly of device
if it doesn' work the first time you can reattempt the procedure
