Solution: USB Memory stick not showing in File explorer

No Comments

Problem

I have some USB Flash Memory drives that I had used on a non-Windows system (ie a TV) so it is using another file system than Windows’ NTFS, FAT or FAT32. When I insert them into my Windows 10 laptop they are connected, ie they are found by Windows and show up under “Safely Remove Hardware and Eject Media” and in the Device Manager. But they are not assigned a drive letter and do not show up as a drive in the File Explorer (aka My Computer in earlier Windows versions) or command prompt.

At first, I just thought that the USB Memory stick was not working but after having the same problem with several USB Memories I realized it probably had something to do with the format on them. I tried to download the HP USB Disk Storage Format Tool, but the USB drive did not show up there either.

So how can I reformat the USB memory stick if it does not show up in the Windows File Explorer?

Solution

I found a solution that works for me from Mosely5165.

WARNING: Make sure you know what you’re doing before trying this. If you select the wrong disk you may loose your data or entire system.

1. Open a Windows Command Prompt as Administrator

cmd.exe

2. Run Diskpart

diskpart.exe

This should launch Diskpart and give you the DISKPART> prompt.

3. List available disks

list disk

4. From the list of disks select the one that is your USB drive, make sure to identify the right one.
WARNING: If you select the wrong disk you may loose your data or entire system

select disk x

5. Create a primary partition

create partition primary

If this gives you an error saying there is not enough space, give the Clean command, then try to create the partition again.

clean
create partition primary

6. Give the following commands.

select partition 1
active
format fs=ntfs quick 
assign
exit

Windows cannot connect to iPhone Personal Hotspot

25 Comments

I have ran into this a few times so I thougt I’d write down the solution as I seem to keep forgetting it. There are probably tons of other problems you can have with iPhone Personal Hotspot and Windows Wifi but this is the solution to one I keep running into.

Problem

I turn on the Personal Hotspot on my iPhone and it shows up fine as an available Wifi network in Windows only the Wifi name looks a little off in Windows compared to the iPhone. My iPhone name is “Max’s iPhone” but in Windows the apostrophe looks “scrambled” and is replaced by two “trash” characters, something like this: “Max¿Ǝ iPhone”.

When I try to connect my Windows laptop over Wifi it just keeps trying to connect – showing message “Checking network requirements” – before I finally get “Can’t connect to this network“. On the iPhone I get the blue Personal Hotspot field on top of the screen flashing on and off while Windows tries to connect.

Solution

Solution is to change the name of your iPhone to remove or replace the apostrophe.

To change name of your iPhone in iOS: Settings – General – About – Name

More info

I just fixed this and unfortunately cannot recreate or remember exact what the scrambled or trash characters in my iPhone name looked like but I think one of the characters was an upside down letter E and/or question mark. So it looks something like this “Max¿Ǝ iPhone”.

So this seems to be what messes things up for Windows.

For me it has worked both to remove the apostrophe or replace it, ie delete it and then type it again. The name will look the same in your iPhone but after this it will also look ok in Windows Wifi selection and Windows should be able to connect to your iPhone Personal Hotspot without any problem.

It seems this problem keeps reoccuring for me. I do not use Personal Hotspot that often so I’m not sure when or why this reoccurence happens but my best guess is that an iOS upgrade or switching to a new device and installing from backup may be the cause.

Currently running iOS 9.0.2 on an iPhone 6 and Windows 10 but I have had this problem in previous versions of both iOS and Windows.

Did this solution work for you?

Please let me and others know by commenting, provide what version of Windows and iOS you are using if you know it.

Windows 10 international support lacking

No Comments

I have noticed a couple of things where Windows 10 does not support international the way I would expect a 2015 operating system to do. I have not found any solutions yet so any more info on these issues would be appreciated.

Compressed (zipped) folder

I tried to zip a folder in Windows 10 by right clicking and then selecting Send to – Compressed (zipped) folder but got this error:

xxx cannot be compressed because it includes characters that cannot be used in a compressed folder, such as ". You should rename this file or directory. 

The folder contains files with Swedish characters åäö in it. I cannot remember having any problems with this in Windows 7?

Calculator

The calculator (calc.exe) only accepts the period sign (.) as decimal delimiter. In Sweden we have comma (,) as decimal delimiter and this has always worked in all Windows programs for as long as I can remember. Of course any properly written Windows app would know to take such settings from Windows regional settings but apparently the decimal separator is hardcoded in the Windows 10 version of the calculator.

Batch rename files in Windows from Command Line

1 Comment

This is an easy way to add a prefix to any set of files in a Windows folder, from a command prompt type this

for %a in (*.*) do ren "%a" "prefix - %a"

 

Tried in Windows 10. Thanks to ofer.sheffer in this Stackoverflow post where there is also an example on how to do this in PowerShell.

Solution: Windows 10 upgrade: “Couldn’t update the system reserved partition”

1 Comment

Problem

When trying to update my Windows 7 Home Premium 64-bit to Windows 10 the other day using Windows Update I got this error “Something went wrong” and “We couldn’t update the system reserved partition”.

After some searching it seems this is related to not enough disk space on update partition, needs to be 50MB (thanks for the informative error message Microsoft…)

Solution

Thanks to Mister_Kurtz who in this post describes a solution when upgrading Windows 8.1. I’m on Windows 7 and upgrading to Windows 10 RTM (Release to Manufacturing) but with some slight changes it worked for me. The trick is to free up 50MB space on the Data partition, which is used for the upgrade, by truncating the NTFS log to 5MB. The original post includes steps to delete language files but I did not have any such files on my computer.

These are the steps that worked for me:

  1. Your user need to have administrator rights (full access)
  2. Go in to Disk Management – Start button, in search box (or Win+R) type
    diskmgmt.msc
  3. On the same disk as your C: drive the first partition will be Data of size 100MB. Right click on the Data partition and select Change Drive Letters and Paths. Then click Add an choose Y: as drive letter (or any other that is available)
  4. Open a Admin Command Prompt – Start button, in search box and type
    cmd.exe

    Right click the cmd.exe program and choose ‘Run as Administrator’.

  5. In the Admin Command Prompt goto Y:
    Run these commands:

    takeown /f . /r /d y
    icacls . /grant administrators:F /t 
    attrib -h -s -r bootmgr
    chkdsk Y: /F /X /L:5000
  6. Output from chkdsk should tell you that you now have at least 50MB free space.
    Retry running the Windows 10 upgrade, i did not need to reboot.
