Uupd.bin Sd Card
Argenta Sugden
My phone crashed (several times) and managed to corrupt my microSD card. It no longer appears to have partitions and shows as 32MB rather than 2GB. That's using testdisk. dd and ddrescue only pulled 30.6MB of null off of it.
Now plug in your disk and run the command again. You will see an entry that wasn't there before. That entry is your device. Write down that device path. If you haven't unplugged all other devices, DO NOT MIX THIS UP WITH ANOTHER ONE.
After creating a dos disk label, you will need to create a partition. Choose make a partition from the menu. Just hit enter and it will give you the defaults. The defaults will make the partition the maximum size of your usb.
I've run across cards in that condition a couple of times. I'm sorry to report that I've not been able to fix any of them. I'm thinking it's probably due to a hardware failure as no software tricks I could think of could get them going again.
I took a ear bud (the little thingys with cotton on one end.. cotton swab).. and wet it with nail polish remover. Then I cleaned the contacts (which were looking very neat and clean to begin with!!) and then wiped it off with a restaurant napkin.. the one that they keep on your table to wipe your mustache.. and then did it again. This time DID NOT wipe it but let that thing dry (does not take long.. about 30 secs).. then poped it in viola.. it was as good as new. (And all that after following all the steps above including trying to write zeros).. and all those started showing 0 bytes. I could recover even old data.
Every time I've seen this exact failure mode, close examination of the micro SD card concerned has shown that I've actually managed to crack it - that is, physically break it - just behind the contact strip, with the crack on the opposite side of the card from the contacts.
The kind of simple micro SD socket that HardKernel uses on its ODroid development boards, which doesn't fully enclose the inserted cards, leaves them particularly susceptible to this kind of damage and SanDisk cards in particular do seem quite physically fragile in this spot.
If you were very very lucky you might be able to restore operation by chemically welding the crack back together with an aggressive solvent like nail polish remover while holding the card slightly flexed in the exact manner needed to reconnect whatever internal trackwork has become separated.
You might even be able to do this by accident while convincing yourself that what you were actually doing with your nail polish remover was cleaning the contact pads. But the card would never be reliable again; if you do manage to fix one this way, your best option would be to image it immediately to a fresh card and then turf it.
I had this problem. First I tried various formatting methods. Ended up using windows diskpart to 'format quick fs=ntfs' just to see if it would resize properly. It didn't. Then I used this SD card formatting utility recommended on the Raspberry Pi site and it did the trick.
A couple of days ago I received a new 32 GB SD card from Sandisk. Upon arrival, I flashed the Retropie 4.1 image for the Pi Zero onto it. I then put the card into my Pi, and plugged it in. Nothing. It would not boot.
I then took it out, and plugged it back into my laptop. The only thing Windows was able to discover was an unknown device, saying that it must be formatted to be used. Upon further inspection, I realized that Windows was seeing 32 MB of raw unallocated space.
I then tried some of the methods that I could find. A normal format does not work, diskpart does not work, and using SD Formatter 4 does not work. Upon doing some research, I realized that when you flash a Raspberry Pi OS onto a microSD card, it creates two partitions, one of which windows can't recognize, and the other Linux can (this however is weird, as in previous times where I flashed an OS, Windows saw two separate devices.
I figured this was because I was using a newer version of Retropie, and it somehow needed to be partitioned in a different way than older versions). So, I booted up Linux Mint on a Virtual Machine, and connected my card in hopes that using GParted I could format my card and start over. However, upon opening GParted and looking at the drive, I am greeted with what is shown below. As you can see, GParted only sees 32 MB device, instead of the two separate partitions which I was hoping to see. I could not interact with the space at all, as it said there was no partition table.
I then attempted to create a partition table, and it completes with no errors, but nothing is actually created. Am I screwed and I need to get a new card? Am I doing something stupid? I'm seriously at an absolute loss at what to do, and any help is greatly appreciated.
I found the issue : the strength of the card was broken and micro power cuts broke the links and create circuit breakages. I only saw it after returning the SD card black side and pressing lightly on both sides. Transformation of the card into a double card ... but not from 32 GB to 64 GB.Fragility of the current cards hoping that they are not even finer in 10 years!
Windows has great difficulty reading a SD card after the raspberry Pi installed files on it. My SD Card had 2 partitions, the first one only being 61 MB, the second one was 26 GB. Next to that, there was almost 1 GB unallocated.
I have same problem with an 16GB SD card of Samsung. After trying all the software solutions available on internet i moved onto hardware issues and figured out there is very small crack on the SD card that can not be observed easily. i observed it with flashlight.
Its cause was the SD slot of raspberry pi. I put the PI in my backpack where he received some kind of force on it that resulted in crack. After this crack the SD Card shows on the windows disk Management as 13MB RAW Disk and noting else.
Windows has a hard time with Linux partitions. If you have access to an android phone with an SD slot just pop it in and format it there. When finished try it out in you windows machine and see if you have it back.
A simial thing happened to me with my 16 GB big SD card that'd only been used in a Raspberry Pi, but hadn't been used for over 2 years. My Windows laptop saw it as 42 MB and even a partitioning tool showed it as 42 MB.
Thanks Martin. Luckily I did have a spare uSD 32GB (Kingston make) card lying around. Also it is already formatted as FAT.
So I deleted all the files from it, then put it in the TInySA Ultra. Phew! It seems to function normally again. I saved a test capture and can view it on PC as expected. So it looks like the original card is simply faulty.
Unfortunately, this problem is common in our time, but not everyone knows how to fix a corrupted micro SD card. Someone calls his fellow programmers, someone runs to a service center, and someone throws a micro SD card into the bin at all. But you be smarter, do not rush. You can fix corrupted micro SD card quickly, easily and without leaving your home.
The easiest way to recover data is to use special software. DiskInternals Uneraser is the best choice for recovering files, even from damaged micro SD cards. This software recovers all types of files (.docx, .ppt, .jpeg, .png, .avi, .mp4 and a lot more), in addition, there are no limitations on the amount of recoverable lost data.
Took a ton of pictures today on vacation. I was able to view them on the camera itself after taking them. Got home, put memory card in my computer, pictures weren't there. Put memory card back in camera, pictures were gone from there too. What the heck?!
I tried running a data recovery tool to no avail. The files it found for me were all old pics. Nothing from today's date so I did not pay the money to recover them. All pictures from yesterday and before are still there.
My brother tried multiple recovery programs and had success with ZAR v. 9.2 (they have newer versions...this is just the one he happened to have from a recovery attempt on his phone a year or so ago). ZAR is the only one that was able to search deeper into the memory card and found all the pics.
Interestingly enough, there were 172 pics that were lost and when he checked them all for recovery and began the process, a progress bar showed on the screen. The first 171 pictures took just a few minutes and only about 1/3 of the progress bar. When it got to picture 172, it took another 10-15 minutes and the remaining 2/3 of the progress bar. Things that make you go hmmm...right?
So, after having them all saved to a folder on his desktop he went to transfer them to a flash drive for me to move them over to my computer and when it got to picture 172, the flash drive balked and said "no room..." This prompted him to investigate further and he discovered that that 172nd picture was 8 GIGS which explains why that last picture took so long during the recovery process! Don't know if that weirdness happened when the recovery was being done or if the memory card is the one that did that and which caused this whole mess in the first place.
Either way, I can't trust the card anymore and now don't trust the brand either. Without knowing what caused the problem in the first place, I'm going back to Transcend and hoping that sticking with a more well known brand will prevent this from happening again.
Be very careful where you buy your cards because the popular brands are frequently the subject of counterfeit producers. A few years ago I bought a couple of Sandisk SD cards from the extremely large online retailer and they were clearly not real Sandisk cards. I had no problem returning them and purchased replacements from B&H which is a reliable source.
Lately even lithium coin cell batteries have become a major target of counterfeit producers and I bought a pair of replacements for my Corvette key fobs from the same place I got the counterfeit SD cards and received a pair of counterfeit batteries. Now I get my replacement batteries from my favorite industrial electronic components supplier, Mouser.
