Windows 10: USB Flash Drive Problem... or ?

I picked up a Hama brand 128Gb USB2 drive a couple of weeks ago from a reputable component supplier. The drive was retail packaged and I have no doubts over its authenticity.

When used on my Dell i5 laptop running W10 insider builds I find the drive freezes when transferring normal types of files (music, pictures etc). Not just freezing, it also locks the PC (not responding) and even prevents it shutting down.

The default formatting is exFAT. I tried NTFS and a quick format took 20 minutes after which it reported only some 66 Gb free, in other words around one half.

The drive was exchanged by the retailer, however the replacement is the same.

Next I try it on my W8.1 Acer laptop and find that while it doesn't freeze in quite the same way, the file transfer still stalls and takes ages and ages. It goes in spurts transferring maybe 10 files at a very low speed (kB) and then stops for perhaps 20 seconds before doing a few more.

A Sony Android TV also fails to even recognise the drive when asked to use it for recording, and Sony specifically say in one document that speed is not an important parameter for that application.

All my other drives (SanDisk, Lexar and Peak etc) all work as expected.

Any thoughts. Is there anything intrinsically poor compatibility wise about high capacity flash drives? I've used 64Gb before and had absolutely no issues.

install.wim is 7GB, how to make a bootable USB flash drive


This is a method to make a ntfs flash drive.

The trial and error step will be booting using Legacy BIOS...

Code:

Code:

diskpart  list disk  select disk W  (change W to the disk # for the flash drive)  clean  create partition primary  format fs=ntfs  assign  exit

This is the link:

The link did not use active so that is why it is a trial and error step.

 

USB Flash drive made bootable

Hi Nelson,

Check if there is any slide switch on the side that provides write protection. It show's a closed and open lock on each side. We suggest to follow these steps below:

• Insert the USB flash drive into the USB port.
• Click Start, type devmgmt.msc in the Search textbox and press Enter.
• Find Disk Drives and expand it.
• Find the USB flash drive you want to format, and double-click it. It opens the
  Properties dialog box.
• Click Policies tab.
• By default, the Optimize for quick removal option selected, switch it to Optimize for performance and then press
  OK.
• Now open Computer. Right click on the USB Flash Drive and select Format. The Format dialog box now appears.
• Select NTFS in the File System field.
• Press Start and wait while the process will be completed.

You can also connect the USB drive on a different computer and try formatting.

Let us know how it goes.

 

help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
