Sandisk Extreme 64GB - Slower write speeds after system format

playing some of my first pc games on this 286. Duke nukem 1

 

Oh yes, I remember Duke Nukem.  Many, many hrs of it.  I wonder if I still have that on a floppy upstairs?  :smileyvery-happy:

 

Would a low-level format be able to help in any way?

 

I honestly don’t know.  But if it doesn’t work you can always reformat.  GD&R  :smileyvery-happy:

 

But before trying the low-level format try reformatting using different blocksizes.  If you’re currently using 8 MB try 4 MB.  If that doesn’t help try 16 MB.  I don’t know what the initial size was, maybe someone with more knowledge than I can step in and give a clue.  And try diskpart rather than the standard Windows format option.  Let us know what you try and how things turn out.

-update-

Checked out that link you posted.  It appears to be for hard drives only.

HDD Low Level Format Tool is a utility for low-level hard disk drive formatting.

So I don’t think it will help with the SanDisk drive.
