Windows 10: sandisk cruzer 32G

There is no need to delete those items from your PC. ReadyBoost is a feature built into Windows 7 8 and 10. That drive must have been setup as a readyboost drive either by accident or by somebody else.

 

Some success. Using that tech Windows 7 pro 64-bit now works with the Sandisk.
Windows 10 does not work......

 

I bought an 8GB Sandisk Cruzer recently and it would not recognize it until I assigned it a letter via disk management.

 

I would think, if this drive had been used for ReadyBoost it would need to be cleaned with Diskpart since boot has some specific settings. Just reformatting does not access this area.

You would need to move any data you want to save off the drive, but if you need the Diskpart commands, let us know.

 

That "should" be automatic, but I have seen that happen every once in a while. One thing is the newer Sandisk thumb drives show up as fixed disks instead of removable media. I don't know why Sandisk did this or what the ramifications are. On the plus side it makes it easy to use those drives for Windows To Go. Assuming you have one large enough.

 

I'm not sure what Readyboost does to the drive. You will have to use diskpart though, as disk management won't let you delete the partition on a thumb drive. It's greyed out for me. I would think clean all should do it.

 

Hi there

Trouble is people are afraid to use the command line these days.

1) Stick your USB into the W10 machine
2) ensure there's no messages or format requests.

Now use the CMD PROMPT in administrator mode and type the following.

DISKPART
LIST DISK (say the USB stick is drive 5)
SELECT DISK 5
CLEAN
CREATE PARTITION PRIMARY
FORMAT FS=NTFS QUICK
ACTIVE
ASSIGN

EXIT.

If you get an error at CLEAN simply ensure you don't have file explorer or control panel open and try again.

Cheers

It's an 8GB and edited my post to reflect that. One would think it to be automatic, but for the life of me it wouldn't show up. I bought it specifically for my 10 ISO install and wasn't sure to format it or not to prep for ISO install. I haven't for DVDs. Basically right click and direct to burn to optical drive D:. I used the Windows 7 USB/DVD Download Tool for the thumb, but it could not see the drive. I scrapped that and burned to DVD in which I had trouble. It turned out that my PSU was on it's way out, so at that time I accredited it to the bad PSU.

Anywho, after up and running again, I saw it in 8.1 Disk Management, but with no letter assigned. After assigning a letter it worked fine.

 

Just make sure you select the correct drive. The clean command will wipe that drive of all data.

 

Thanks everyone for responding.
I'm in a new ballpark.... Can't find Cmd Mode or Administrator...
Will keep looking. Maybe I'll get lucky...

Also my Sandisk drive is a letter and not a number.

 

Right click on the Start menu, select Command Prompt (Admin).

 

In diskpart its a number not a letter.

 

You may be on to something regarding the flash drive in Windows 10.

I took a 4 GB flash drive and went through the Diskpart commands on Windows 7, 8.1 and 10. The commands on Windows 7 and 8.1 worked fine, but this is what I got on Windows 10.

After I got the indications below, I removed the drive and reinserted in another USB port. The commands were successful this time as shown below..Edit: It turns out the partition created, even though successful, was not valid on an 8.1 system.

The Event Viewer shows this:

The source is the VDS Basic Provider.

Since I do not know exactly what this means, I will have to do some checking. As far as I know, nothing was open that was accessing the drive, not even Explorer. I do notice in Explorer the drive shows under "This PC" and as a separate entry on the same level as Network and This PC. Whether the "This PC" listing is expanded to show this drive does seem to make a difference as to whether the drive is accessible.....

 

More info on my previous post. After I tried to use the drive after Diskpart appears to have succeeded, I got a message about inserting a drive, so it was not accessible. When I went into Disk Management, the drive showed as unallocated.

When I tried to add a partition in Disk Management, I got the options below. I don't think the NTFS option should be missing, or FAT should be the default format type.... Sorry the snipping tool will not allow me to show the options for formatting, but FAT and FAT32 are the only options.

 

I'm pretty sure FAT is the default for any blank thumb drive I've used. It should default to FAT32 for larger drives. NTFS should be listed though, it is for me?
