I am in the process of replacing my first Sandisk Extreme 64 GB due to speed issues. I was tinkering with Parted Magic but I cannot make the flash drive appear on the list. The notice "This routine can only run for disks supporting the Security Mode feature set" keeps showing up. I managed to have my external USB HDD shown in the list, but not anymore.
How did you manage to make the flashdrive appear on the ATA Secure Erase list?
Thanks in advanced

Nevermind, I was running Parted Magic on a Virtual Machine. I burnt the iso on a Usb stick and booted my laptop to a true non-virtual Parted Magic session. My internal HDD was recognized and thus I could ATA secure erase my Sandisk Extreme.
Writing speeds went from 10 mb/s to 190. Could not be happier.
Again, thank you for the tips on bringing this flash drive back to life.

I've just bought a Sandisk Extreme 64 gb and wait for it... I'd like to format it to extFat, even before the first write/read. Reason: need/want larger files than just 4gb. So today I said to myself let's a bit of reaseach and I was really afraid to find this thread and well here we are. I mainly bought this flash drive because its well promoted speed and don't wanna lose this feature.
So for those who were able to recover original speeds (e.g with parted magic), have you guys formatted to fat32 or got the original speed with other formats?

I'm a huge fan of Western Digital and WAS a fan of SanDisk but after owning this stick it will be my last SanDisk purchase.

Or just make sure you don't blindly format it cause that's what you always do. New flash drive = new technology = new use proceedure. If you've been in IT for any period of time you should have seen other equipment and processes change, flash drives are no different.
" i didn't think twice about formatting this stick"
If you want to make sure this is your last Sandisk drive you will have to think twice before buying another drive. Sure you're up to it?
Important files = Backed up files

Sure, technology changes but there was no warning that came with the stick about formatting and worse than that SanDisk have zero tools to format or restore it to its former glory. Really the only way someone would learn not to format these sticks is by formatting them and then searching for a solution when it goes belly up. Otherwise there no way of knowing this specific issue (and it is an issue).

This is exactly what the issue is about. Formatting the factory filesystem has absolutely nothing to do with the slowing speeds and I don't know why it's being said that causes the problem. I've got 2 of these drives and one I formatted to NTFS and the other is still exFAT and both have slowed down in write and reads.
Using SecureErase in PartedMagic has restored it back to normal but surely the flash drive controller should be doing this automatically. I've already contacted the retailer I bought it from and requested to return them. You shouldn't have to manually maintain the drive yourself to keep it working fast. It would have been a great USB drive if it weren't for this issue.
