The Problem:

 

I have a three year old Dell Inspiron 14R.
 

The Flash Drive is a simple Sandisk Ultra USB 3.0.

 

When I plug it in, it constantly disconnects and reconnects, sometimes more than two or three times a second.

 

When it does  manage to remain connected for more than a few seconds, as soon as a start a file transfer it will disconnect immediately.

 

Also there is a popup saying "(G:\) There is a problem with this drive. Scan the drive now and find it."

 

If I click scan, immediate disconnect and failure to scan.

 

I have three USBSS ports on my laptop, all with the same problem (with this USB drive). 

 

It works flawlessly on my Xbox, another laptop, and at multiple computers at work, but it has never worked on this one. Other USB devices and flash drives work  perfectly.

 

What I've tried:

 

Power Options>Change Plan Settings>Change Advanced power settings>USB settings>USB selective suspend  

 

I disabled both options. This worked for many people with this problem.

 

 

BIOS Disable Legacy USB

 

This didn't help.

 

 

Disable the USB controllers in the Device Panel.

 

Also didn't help.

 

 

Updated all my drivers for motherboard, USB, etc.

 

Still nothing,

 

 

What else can I try?

Check the USB Flash Drive for errors by opening Command Prompt as a administrator and type Chkdsk X: /r command and press Enter key. Replace the X: letter with USB flash drive assigned drive letter.

It isn't able to complete because of it disconnecting. It has about half a second before it disconnects.

I understand but have you try the Chkdsk command maybe this time it will work as no GUI is involved.

Right, I'm saying I tried, I either get 

 

Cannot open volume for direct access.

 

or, on the off chance I push enter on the .2 seconds it's connected, I get:

 

The type of the file system is FAT32.

Cannot read boot sector.
 
then back to 
 
Cannot open volume for direct access.

Well looks like USB is malfunctioning or file system is damage try Chkdsk  X:  /r  /x   command this command  forces the volume to dismount first if necessary.

It started again, but this time I was prompted with a choice to try again. I clicked try again, looked like it was working but it didn't do anything after the prompt.

It's been stuck here at 0% for almost 20 minutes now (no more prompts or anything).

 

 

C:\WINDOWS\system32>chkdsk g: /r /x
The type of the file system is FAT32.
Volume Serial Number is DB83-25C9
Windows is verifying files and folders...
0 percent completed.

Don't interrupt the repair process time limit for repair to finnish is impossible scan and repair process can take long as half an hour or days it depends on size of the scanned device and how much files are store on it as well how bad is the device damage.

Have you tried this flash drive on another computer?  Does it exhibit this behavior there?

Have you tried other ports on the computer?  Does it exhibit this behavior there?

Have you tried another flash drive that works without problems on another computer?  Does it exhibit the same behavior?

Chkdsk never got past 0% (and I left it ton all night) 

 

I went to work today, the USB works perfect on every computer there.

 

Bought a new USB 3.0 sandisk (different model) and it works perfect.

 

My problem wasn't solved, but I live in Taiwan and a new 128GB drive was only about ~US$5, so it's no big deal.

 

Thanks again for everyone's help!
