SSD Data Removal Question

[Rambo3456]

Hello Every i had a question regarding SSD Data Removal so to give you a sort of back story i am a big security freak and allways want to be able just delete my partions and all my data on my hardrive if something ever goes wrong like a virus or some sort of windows error any ways my friend at school told me that it is impossible to fully delete all data unless you use a jumper and the SSD i have never heard of this and am not familia rwith SSDs is this true please tell me all comments are appreciated

No... This is not true. On SSDs you just have to erase the data and it's impossible to retrieve it as long as you're using an operating system that supports TRIM and the SSD support TRIM too. Whoever this is from your school has no idea what they're talking about.

if its a new ssd just use it, you won't have any problem. getting back deleted data from fat 32 is not a easy task, unless someone is determined to get your data its not easy thing to do.

the easy way is to encrypt your data, and  just dont give the next guy the key.
 or you can use the secure earse function on most ssds.

You can use secure erase software to completely clear an SSD, in regular use they don't delete their data they just remove the pointer files and when new data is added writes over the old stuff, meaning if you just reformat a drive you can potentially recover all the data from it since it's just had the pointer files removed.

Isn't that not necessary as long as TRIM is supported, or am I wrong?

due to the way the ssds do wear leveling, you can write over a file, and the old file will still be there as its using different blocks

Its pretty easy to get data back, but depends on what happens.

most people won't just get a completely erased ssds data back.

but if you delete a file, its very easy to get back, secure earse is hard to get back.

Not too sure actually I was always under the impression that it did that to prevent excessive writes on the flash, but if TRIM just clears it then that data at that point would be close to irrecoverable.

i didn't mean a single file. i was thinking the ssd as a whole.

TRIM will only clear sufficiently large segments. I believe most use 256KB-2MB blocks. Once TRIM sees the block is [fully] marked, the block is deleted and reused.
