Hello,

I have a 128GB SD card that was used as auxiliary storage on my smartphone, which was working very well until yesterday.

But today, I can't open it.

I took it out of the smartphone and connected it to my computer, and it appears as CARD (F:), whereas before it was under SDHC (F:).

There is now only one file on it, uupd.bin, which I can't open.

The card now indicates a storage capacity of 1.86 GB.

I tried to repair the card with CHKDSK in the command prompt, but it didn't work.

Do you know of any way to repair the card or recover the files?

Thank you in advance...

Hello

Nothing is guaranteed in this area unfortunately, but it's worth a try.
If nothing works, it means the content is lost, and perhaps the card is damaged.

Best regards

Hello,

Have you solved your problem?

I have exactly the same issue. It's nothing important so I formatted it. Despite this formatting, it remains at 1.86Gb instead of 64Gb with this uupd.bin file. And it remains unusable.

Have a nice day.

I'm having the same thing happen to me, I've tried everything, safe mode doesn't change anything, I think the file is dead, we need to throw the SD card out.

Out of curiosity, what card was it? (brand and type?)

Hello,

The issue has been reported with many SD cards and eMMC Flash drives, so it is likely more or less independent of the brand and occurs more readily during an improper disconnection or when transferring between two heterogeneous devices (phone/PC...) resulting in the infamous system image bin being written to the card, which is FAT16, explaining why we only see 1.86 Go.

If the card is corrupted, losses and gains, the only hope, which I do not believe in, is that this partition has not been formatted for this system image, in which case we might still be able to access the others via a partition manager.

it's not even a brand name but I bought it at Boulanger so it's weird and it was a 128GB

We cannot unless, and I do not believe, there were other partitions that would be accessible by a partition manager (Aomei Partition Assistant, Gparted...).

The partitions of a USB key have the peculiar characteristic, if they exist, of not being directly accessible by a disk manager but often through, which is not the case here, only a multiboot manager that allowed them to be created.

Hello,

So if I understood correctly, if, like in your example, you make the F partition bootable, it is then no longer possible to go back? Is this partition doomed for life to remain a bootable MsDos partition? Is that right?

Hello,

No: the corruption of the card means that a bin image was written to it, we didn't make it bootable on purpose and just because an image is bin does not mean it is DOS.

You can only, if you have time to waste and for the fun of it, try to see if a third-party utility (Aomei or Gparted as I suggested, but also, for example, HP Format Tool or mkbt) allows you to view the contents of the key as a partition and format this key, but it is likely that it is corrupted and that you won't succeed.
