does win7 cd reformat on ssd not fully clean it?

post #1 of 5
Thread Starter 
im just curious because im having nothing but problems lately with my computer and i did 3 reformats on the same force 3 ssd in a day (dont ask) so im wondering if using the windows 7 cd reformat method isnt good enough

here are my read write times which look great... but i just feel weird about formating so many times with ssds being the way they are...

naw its just alot of issues but they were partially resolved im just curious if it was not as good as another method such as clean erase or whatever

i dont seem to have any read/write issues just im curious to what the pros and cons are of clean erase compared to windows 7 cd format

I believe Clean Erase goes through the whole disk/SSD and writes 0's to every chip, thereby "cleaning" it and it is quite a lengthy process depending on how big a disk is. It took 4 hours for my 1TB HDD. When you format a disc, all you are doing is killing the sector on the drive that references (points) to the different folders and their structures throughout the disc. Therefore, when you format a disc, you aren't deleting anything and that's why data is still recoverable when you simply Format it. But your OS looks at the drive and doesn't see a File Structure like NTFS or FAT32 and just decides that the drive is Unreadable in its current state.

Both work fine, except in an SSD's case, wiping everything with Clean Erase would give your SSD back its factory performance condition. This is because an SSD's write performance deteriorates the less empty space there is. Read speed is largely unaffected. You shouldn't have any issues, but you may have a slight write speed loss because you formatted.

I wouldn't worry though since 95% of what your computer does is Reads and not Writes.


I hope this clears things up

The format process doesn't touch any of the data on any drive regardless if it's a hard drive or a solid state drive or even a flash drive. When a drive/disk is formatted, the Master File Table is replaced with a fresh (blank) one in the specified format (hence the name "formatting"). The Master File Table is what the OS uses to know what is on the drive. When you delete a file, all you're actually doing is removing its reference from the Master File Table. That's why formatting and deleting is extremely fast.

So if you really want to wipe the data completely clean, then you can use Secure Erase (a.k.a. "HDDErase"):
