Windows 10: sandisk cruzer 32G

It may depend on the size of the drive what shows as primary, but when I put the drive on the 8.1 system it showed Fat32 and default and NTFS and exFAT along with FAT, after I switched the port it was plugged into.

I have just done the same procedure with a Patriot 32 GB USB 3.0 drive and that drives seems to behave the way I would expect. So far no problems in Windows 10 or 8.1.

I probably need to clean several of my USB drives, so I will check each one as I clean it. Maybe the original 4 GB drive (Verbatim) is not compatible although the Microsoft listing shows it is with 8.1.

 

I had Classic start on windows 10. It disappeared.
On he regular windows start is found the administrator and the cmd prompt.
Got to Clean and it died there.

 

You might try to clean it in Windows 7 or Windows 8. I have now tested two Verbatim flash drives and they both have the error. The two 32 GB drives, one a SanDisk, seem to be OK.

 

In Windows 10 I finally got all the way thru Diskpart. The Sandisk drive is now ntfs.
BUT, I am unable to move anything to the drive.

The Sandisk no longer works on Windows 7 pro 64-bit. Unable to do anything there.

 

Look at the drive in Disk Management and see if it actually shows a healthy partition. When I was using Diskpart in Windows 10 it would, on occasion, show as successful but the drive had not been configured.

It may also be you need to add a drive letter, as was mentioned earlier. If you are not using the assign command after you create the partition, it may not pick up a letter automatically.

 

My Sandisk Cruzer finally bit the dust on my Windows 7 pro 64-bit computer. But Wait there is
more..... I went online and started reading about Flash Drives. It seems that different flash
drives can only beformatted the way the mfg lets it be formatted. For EX: PHY can only be
formatted "exfat". I don't know the way Verbatim disks can be formatted. The Sandisk seems
to work for "Fat32".

So I trotted over to wiffies computer (running Windows 7 pro 32-bit) and formatted the
Sandisk drive to Fat 32. Copied and Pasted several programs from her computer to the
Sandisk and it WORKED!!!!
Went back to my computer running Windows 7 pro 64-bit and the Sandisk worked there.
Haven't tried it on Windows 10 which I guess will not work. At least I know that I don't
have tojunk the Sandisk.
Nothing is ever easy....

 

I have a dozen or more thumb drives of varying sizes. Mostly Kingston but some Sandisk too. I've formatted them as FAT and NTFS with no issues. At least non that I am aware of.

 

I just tested the Sandisk drive on Windows 10 on the 64-bit computer. Nothing showed
that I created on the Windows 7 pro 32-bit computer. I would gather from that, that the
windows 10 OS doesn't like Fat 32. If I right click on the drive and click in properties,
the disk shows it contains 40,000+ bytes. I'm dead in my tracks.....

 

I have a sandisk cruzer 32gb formatted ntfs and it works fine. I also have a 16gb pny usb formatted FAT and it is OK too.

I was reading sometime back that cruzers that had some bit setting flipped which made them show as fixed rather than removable media. You could try flipping it back with this lexar "bootit" utility and see if it works http://www.computrogeek.com/2013/06/...load-2013.html - the comments say it works with sandisk but I've not tried it...

 

In Windows 10 on the 64-bit puter I finally got it to format as NTFS.
But Ready boost is not cooperating. I click on "do not use this device".
Set the space reserved for system speed to as low as I can set it.
Click Apply and Ok.
Makes no difference as the next time I look at it is back to where it
was the 1st time (30364).
So "readyboost" is eating up 71,647,232 bytes of my Sandisk.
When I click on "properties" Windows 10 says that the Sandisk is working properly.

 

Did you use Diskpart to clean the drive from your wiffie's Windows 7 computer?

Windows 10 does fine with Fat32. But there does appear to be some difference between 8.1 and Windows 10 regarding these types of drives. I wonder if the new build does the same thing....

 

Success but oh my.....
From the trouble I had, I can only assume there are many errors in "partdisk and Readyboost".
I had to use "MiniTool partition wizard" to activate the Sandisk.
I never could get all the way thru Partdisk without some kind of error.
At this point I have a working Sandisk but Readyboost has gobbled up 117,166,080 bytes.
This is unacceptable.......
I have to admit that my knowledge of Partdisk is almost nil.

 

If you formatted in NTFS a small amount of space is lost to the file system. My 64 gig Kingston thumb drive shows 1,458.778,112 bytes used. That's 1.45 Gigabytes. 117,166,080 bytes is .177 Gigabytes. If I got the math right.

 

Could you do something for us? Open the Administrative Command prompt again and start Diskpart with the drive installed.

Use Diskpart to select the drive and then list the partitions. Maybe we can see something from that. You can copy from the command prompt and quote the response on the page, as seen below. Again, make sure you select the correct drive.

If you decide to try and clean the drive again, copy that response also, maybe we will see why it isn't working. I have never used Ready Boost but I suppose I will try and see if my system will work. I would then possibly be able to see how it is configured.

What model is your Sandisk?

 

Hi there

If you use the CMD PROMPT to create a pratition on the drive you should also include the ACTIVE command in the list after you've created and formatted the partition . Run the sequence again and add these two commands

......

ACTIVE
ASSIGN

now exit
