Go 60 - MDC has corrupted my satnav's SD card

It would appear that MyDrive Connect has corrupted the SD card I was using in my device. Note that this is the second card it has broken.

ACTION TAKEN
1. Remove SD card from device
2. Insert card into adaptor - make sure adaptor is unlocked
3. Insert adaptor into card reader and insert reader in to computer
4. File explorer recognises a USB device, insists it must be formatted
5. Attempt to format - Windows says device is locked.

ADDITIONAL ACTION
+ In Windows Device Manager, navigate to 'Disk drives', select 'Multiple Card Reader USB'
+ Right click and select 'Uninstall device' (ignore warnings)
+ When complete, 'Scan for hardware changes'
+ Repeat steps 4 and 5 above

I have also performed factory reset on device (I really don't need pre-installed maps of Australia and New Zealand), so I don't know what else I can do. I don't want to try another card and risk corrupting a third one. Has anyone got any sensible ideas?

DETAILS
Device = Go 60
SD card size = 32gb
Purchase date of card = 9 May 2021
OS = Win 10 20H2
MDC = 4.2.11.4200
Location = United Kingdom

    Hi
    @nuffznuff
    Welcome to the site
    I always use the SD Card Association formatting tool....

    Download for Windows.... https://www.sdcard.org/downloads/formatter/sd-memory-card-formatter-for-windows-download/

    Download for Mac... https://www.sdcard.org/downloads/formatter/sd-memory-card-formatter-for-mac-download/

    After you have formatted the Memory card....
    I use the 'Overwrite Format' option....
    (Note the overwrite option can take a while to complete)

    Insert the Memory card into the PND... It should detect the card and offer to format it... Choose the Maps format option....
    Or... Tap 4Dot (.... Menu) --> Setting --> System... Choose 'Format memory card'... Choose the Maps format option....

    Stay Safe... ATB YFM

    In reality, you can't physically lock a Micro SDHC Memory card there is no lock switch....
    But it can be locked (Read only) with a software command....

    Thank you for returning so qucikly.

    Good news: no errors encountered
    Bad news: no further forward

    I followed your very helpful instructions, but the disk is still read only.
    I have tried to set readonly, then clear readonly (you never know...). Removed the SD card, reinserted - same again.

    I put the card into the TomTom device to format it: TomTom doesn't recognise the card.

    Micro SD card showing raw file system
    RAW is a “format” that an SD card acquires when, for various reasons, its file system is damaged. A RAW SD card, unfortunately, becomes unreadable by any operating system. RAW, here, means "raw material"; that is, in order to, say, return to NTFS format on FAT32 SD card, you need to do something with it.

    How do I change my raw SD card to FAT32?
    Right-click to Format RAW SD to NTFS or FAT32
    (1)... Connect your SD card to your PC and go to "This PC".
    (2)... Right-click on the SD card and choose "Format".
    (3)... Click "Restore Device Defaults" in the popup window.
    (4)... Choose the desired file system FAT32, exFAT, or NTFS and click Start to begin the format process.

    Thank you for persevering, but the problem is that Windows says the sd card is write protected, and cannot format it. These cards are not expensive, but the cost adds up.

    It would appear that it is not possible to save the card.

    Please consider the matter closed.
