Clean erase SSD to clean install Windows 7
I think I have a virus or malware and have been unable to get rid of it after many tries, and I am having multiple problems with this home built computer running Windows 7Pro 64bit. I installed a retail version of Windows 7Pro 64bit and I have my original installation disk. I want to do a clean erase of my 480GB SSD and then a clean install of the same Windows 7Pro 64bit. Can you tell me how and provide any cautions etc. Thanks.
We made a suggestion on Eraser software for a user form seven forums, here is another user Joseph from seven forums asked about how to make a clean install of Windows 7 on a clean disk when he thought his SSD might be affected by virus or malware. And the administrator Shawn provides a solution and a link to clean install Windows 7, Shawn is right that a normal clean install on SSD will also wipe the drive.
But what if Joseph is using HDD instead of SSD, will Shawn's proposal still work? Will reinstalling clean out the virus on HDD? Not exactly, unlike SSD has TRIM settings, HDD has different way of storing and deleting data, in HDD, delete or format will not ensure completely deletion of data but make sure read-write efficiency instead.
Then how to clean install Windows 7 on a clean HDD?
Firstly, we should wipe the HDD to make it clean. Download ByebyeData Eraser and create a boot CD in it. here is the guide on how to create a bootable CD.
Secondly, we boot from CD and use the function Erase disks in ByebyeData Eraser to make the disk clean. Don't forget to choose a wiping method from the giving list.
Thirdly, Click Erase Now and confirm this step to make the disk clean again.
Now this HDD is cleaned, we can follow the steps on clean install Windows 7 and make this hard drive work again.
NOTE: the more passes you choose, the more time it will cost and more secure the disk will be. That said, 3 passes is definitely enough for a clean install of Windows 7; And please make sure you have a backup on important files, photos, videos and other documents, once the disk is erased, nothing can be recovered.
