Sandisk Extreme 64GB - Slower write speeds after system format

Hey Ed thanks for levelling with me :wink:

I did learn something today, and I’m the type that remembers stuff so i guess thank you for teaching an old dog some new tricks. Oh how i treasure old memories of playing some of my first pc games on this 286. Duke nukem 1, Golden axe, Alleycat etc D:

I think my device is broken now tho (sandisk extreme 64gb). My computer gets very slow and somewhat unresponsive when it’s plugged in. It was very bad after the unsafe removal, so i just formated and turned of cahing. It’s much better now but still leaves much to be desired concerning transfer speed. But at least it stopped doing that fast burst and then stall. Right now it’s runing at a pathetic 30-40mb/sec. I also have a transcend usb 3.0 stick and that one is working just fine…

Would a low-level format be able to help in any way? getting it back to factory settings or close. Stumbled upon this HDD-LLF-Low-Level-Format-Tool
