Problem with my 16 GB Sandisk OTG

Problem with my 16 GB Sandisk OTG


I tried all USB ports with no success. Computer does make the sound suggesting that the device is connected but nothing shows up on screen.My pendrive shows as ... (3 dots) in " Safely Remove hardware and eject media" and when I click these 3 dots - nothing happens.

I tried to connect other Pendrives in my desktop pc and laptop and they all work fine.

I tried to plug this 16GB Sandisk OTG drive to another Laptop and it does not show up there as well. It is reocgnized in computer management but not in Disk drivers but in USB controllers as Mass Storage but it does not show an exclamation mark. I tried to klick on drivers update but it says that the driver installed is most update .

I am having one Desktop PC and Laptop both running Windows 10.


Although this OTG Sandisk 16GB Pendrive works on my Mobile. When I insert it - it said the drive is damaged and then asked me to proceed for formatting, which I did. After the formatting on the Mobile itself, it started working but does not work on my Laptop as well as on my Desktop PC.
I have so far tried various methods like formatting, wiping, assigning drive labels, assigning drive letters through Different Partitioning Tools but of no avail. Also tried through bootable Partitioning Software to format, assigning drive letters etc but without any success.
Any help will be highly appreciated,
Thanks in advance

Sounds like the drive might be defective.

Does it show up in disk management with a drive letter ? 3 dots in Safely Remove meaning it's not being recognized, as 3 dots are normal if nothing is plugged in, FYI.Since has dual port micro and regular USB, possible one is bad, since on mobile device it's using Micro port.

Thanks Mr Ram1220 and Jds63 for your response. In the meantime I have fixed my problem and my Sandisk 16 GB OTG is now working fine. I have taken the following steps:
1 Deleted the partition.
2 Recreated the MBR partition
3 Converted the partition into NTFS assigning Drive Letter and Label.
4 Opened Device Manager and removed drivers at two places - first at storage devices and second at portable devices.
5 Booted my Laptop and I found my USB drive showing on My Computer. For trial i loaded few files and everything was working to my satisfaction.
Thanks for taking interest

Your welcome ! Strange part is, yes the partition style should be MBR, but the format should be FAT32 (Default) not NTFS. This would be for USB flash drives.

See a flash drive on mine.

You can choose to format a flash drive as NTFS. Especially if you want to put a file >4gb on it.

I see choices when you do Format, just wondering how this did fix it. I put large files on a USB Flash before and never changed the default of FAT32. Maybe there is a difference, i did not know as only used this for External Hard drives NTFS.

FAT32-formatted drives do have a limit of 4GB minus 1Byte for a single file size, NTFS gets around that but there may be other issues in using NTFS, one is if the drive is also used on a Mac OS X computer, Linux doesn't seem to have much trouble with them. Another limit of Windows is in formatting FAT32 partitions of 64GB, have to go with NTFS. But I recently got a SanDisk 64GB MicroSDXC card for my Win10 Notebook and it is formatted as exFAT, seems to be okay.
A couple of caveats:
1. 64-bit computing for using/needing more than about 3.0-3.5GB RAM
2. Use NTFS if needing to store files at 4GB and larger
3. 32-bit computing for some older programs
4. 64-bit drivers for devices on 64-bit computers
5. 64-bit hardware can run a 32-bit Operating System but not the other way around
6. 64-bit Windows can run many 32-bit programs but not the other way around
7. 64-bit seldom can run 16-bit programs although I have one program that the installer wouldn't work but copying the program from a 32-bit computer did let the .exe file work
Okay, it was more than a couple.

Mr Berton, Mr Jds63 and Mr NavyLCDR, after setting the pendrive workable for Laptop and Desktop PC, it stopped working for my Micromax Mobile owing to incompatible file format. I had to reformat the same to Fat32 and make it
workable on all devices. Now it works on all 3. Thanks for taking interest.

So assuming it was always formatted to FAT32 when it wasn't working, till you changed it to NTFS to get it to work, then it didn't again. Guessing it had errors on it.
