Re: SanDisk Extreme USB 3.0 (64GB) Flash Drive not working

So I have the same exact problem.  I received a 64GB extreme USB drive and as soon as I tried to copy files the copy failed and the system froze up.  I could read the files on the drive just fine.  So I tried to format the drive using the exFAT file system but the format fails every time.  It almost appears like the drive is write protected or the drive shuts off and stops communicating after a few seconds.  This is the second drive that I have, and both have resulted in the same issue.

Re: SanDisk Extreme USB 3.0 (64GB) Flash Drive not working

I had the same problem.

 

My mac hangs when I plugin the flash disk

 

It was detected in XP... but when I tried to reformat using HP format tool, it fails to format... using FAT32 and FATex

 

solution:

 

I used Easus Partition Manager.... deleted the partition and created a 32gb primary partition... formatted... now it's usable in windows and mac... but using 32gb... at least I was able to use it.

Re: SanDisk Extreme USB 3.0 (64GB) Flash Drive not working

Just received my nice new Extreme 64GB flash drive in the Mail from TigerDirect.com...  Plugged it into my Windows 7 Pro PC (USB 2.0) and I can't do anything with it.   I can see the files that were already loaded on from the Factory but I can't even create a new folder.   I've tried several things including restarting the computer but Not formating.    Why do they sell a product that doesn't work???  I guess the "EXTREME" stands for EXTREME measures need to be taken to get it to work....    I guess I'll have to send it back to TigerDirect - After I give it a BAD Review...   

 

My PC is:

 

Toshiba Satellite L755D-S5104

Windows 7 upgraded to Professional SP1 - 64bit of course

AMD A6 Quad core processor

4GB Ram

 

If anyone who is more computer savy then me can figure out how to get this to work - I really would appreciate a heads-up!

Easeus worked for me too, apparently windows can't recognize more than the first partition on a removable drive, there are three partitions on 64gb drive, I deleted them all and then formatted with ntfs, works great now

All of SanDisk Extreme's USB flash drive's problems FIXED

I was looking online for solutions because my SanDisk Extreme 64GB USB 3.0 Flashdrive had the following problems

 

-SanDisk Extreme wasn't being detected as "SanDisk Extreme" in Device manager. Instead, it was being detected as various different Disk Drives.

 

-SanDisk Extreme couldn't be given a driver label in Computer Management under "Disk Management".

 

-SanDisk Extreme would be detected in the Computer, but wouldn't appear as a removable storage device in the "My Computer" window

 

-SanDisk Extreme was detected and usable when inserted into 2.0 USB ports but not in USB 3.0 ports.

 

-SanDisk Extreme's LED when inserted to the drive will stay on and the USB flashdrive will not be detected by the Computer

 

-SanDisk Extreme's LED will turn on once inserted into the USB 3.0 Port but then turn off approximately one second later and will not be detected by the Computer

 

I'm running Windows 7 64 Bit.

 

After running tedious and unsuccesful solutions and procedures found online e.g deleting registries from the SanDisk Extreme, trying to assign it a Drive letter, resetting computer to factory settings, I found a solution.

 

IF YOU HAVE TRIED TO FACTORY RESET YOUR COMPUTER AND THE SANDISK EXTREME DOESN'T WORK, THIS HAS A VERY HIGH CHANCE OF WORKING FOR YOU!

 

-FIX-

1) grab your SanDisk Extreme and slowly, but not completely, instert it into the USB 3.0 Port.

 

2) Make sure the USB stick is NOT COMPLETELY INSIDE THE PORT.

 

3) As you're inserting the stick into the port, the LED in the USB drive should turn on. From here a couple of things can happen

 

4) option 1: The LED will begin to blink. This means that the USB drive has been detected by your computer and is fully functional

 

option 2: The LED of the drive will stay on and not blink: try re-doing steps 1-3.

 

If the LED of the Flashdrive remains on once halfway inserted to the USB port, try inserting it completely into the USB port.

 

------------------------------------

 

This has worked on me all the time.  I don't know if it's a software or hardware issue, but the solution above has worked on all devices that couldn't get this device to function properly in. 

 

If a video is needed to provide a solution to this porblem to be credible I will do it. (:

 

Have a good day everyone!!

Re: SanDisk Extreme USB 3.0 (64GB) Flash Drive not working

Search for "Mini Partition Tool" and delete the current partition and again choose the partition and after that format it.

may be Current/ Primary Partition.
