MSD card Crashed on 436HP

[Heidi750]

My MSD card in my 436HP crashed a few weeks ago. I bought a new card and tried to format it to work in my scanner. But, it didn't work.
So I bought another card and got the same results.

Format Info: 16 GB card
Fat 32 (Default)
Allocation unit size: 64 kilobytes ... format (should I be using a special setting here?)
Option=Quick Format ...
Am I missing a step?
Is a 16GB card too big?
Suggestions???

Did you use "Sentinel" to clear user data?
That also wrights files to the card so the scanner can see it...
Other wise the scanner doesn't know what to do with it....

16Gig is fine... It can use up to a 32Gig card...

16gb is not "too big". Larger than what the scanner needs, unless you plan to do one heck of a lot of recording, but it's still a size that the scanner can handle without an issue.

Instead of formatting the card using Windows, use the SD Card formatting software:
SD Card Formatter - SD Association

You do want to format it as Fat 32.

After formatting the card, use the "Clear User Data" option in Sentinel, under the drop-down Scanner menu.

That sets the card up to be used by the scanner, creating the folders that will be needed.

Once you've dome that, then use Sentinel to write your Favorites lists to the card. Now, your replacement card has the database & Favorites lists, as well as other files it needs to operate correctly.

To add to above... Don't do a "Quick format"... Let it go thru the whole card...
Quick format just does the allocation table... Full format will check the card for errors and wright any bad sectors out...
It can take several min to do a full format...

Yep

I forgot to mention that. I also use the full (overwrite) format when trying to do a little COR on a questionable card.

SD cards use only the allocation table when doing format. When you select non-quick it just writes data to each cell, exactly as you do when you normally use the card, and it will handle bad and slow cells in the exact same way regardless when the writes are done. So no need to fill the card with dummy data, but it wont hurt it either, just one write cycle extra of the 100.000 or millions available. Any errors will be detected and handled during normal use.
