Samsung EVO 32GB card currupted[Got into Raw format] Please help

[sudheerkdty]

While I was using the device I got a pop up showing, SD card is corrupt.

• I tried formatting with windows and got error message windos was unable to complete format

• I tried with chkdisk and got error saying the partition is RAW format

• I tried using Minitools Partition recovery wizard. It showed that there is no partition. So I created a partition, and applied. After finishing all the operation, It showed bad disk

• I tried to format with ubuntu and got the following error.
  

  Error creating file system: Command-line `mkntfs -f -F -L "" "/dev/sdb"' exited with non-zero exit status 1:
  stdout: `Cluster size has been automatically set to 4096 bytes.
  Creating NTFS volume structures.
  '
  stderr: `/dev/sdb is entire device, not just one partition.
  mkntfs forced anyway.
  Failed to sync device /dev/sdb: Input/output error
  Syncing device. FAILEDFailed to fsync device /dev/sdb: Input/output error
  Warning: Could not close /dev/sdb: Input/output error
  ' (udisks-error-quark, 0)

• I tried with gparted. Same like minitools, It showed my disk as unallocated partition.
  I tried to create a partition and got this error
  

  No partition table found on device /dev/sdb

  Then I tried to create a partition table and got the errors
  

  Input/output error during write on /dev/sdb

  Error fsyncing/closing /dev/sdb: Input/output error

  Error opening /dev/sdb: No medium found

If there is no way to fix my card, Samsung may provide replacement. But I am concerned about possibilities of Data Recovery and Misuse if I give my card to them.

Try with this with gparted:
Device>Create partition table...

Then try to format your sdcard

I had the same issue once with the same card. Thank god I made a backup earlier. I am not sure if this is a Moto problem or the card's but I did found out something. When Marshmallow asks to format the card as internet or portable, it doesn't quite reads the type. But once you format it as internal in order to move all the apps and then decide to format it as portable later, the phone acts weird and ultimately, the card starts having problems. If you ask me personally, I always hated this "format as internal" ****ty feature in Marshmallow. I really hope Nougat will fix this ridiculous issue.

I had bought my Evo from Amazon and they always have an amazing return policy. My card got corrupted within a month and I called them immediately to initiate a refund process. But the fact is the card was never corrupted. The phone made it that way! Now I am using a Sandisk Ultra 16 gb but I only inserted it after formatting it in my pc as FAT32. And then made it portable in my Moto of course. These memory cards usually have a very low life. It gets corrupted quite easily if proper care is not taken.

I suggest you return your card or get it fixed under your warranty asap man. And always remember, do not format it as internal memory. You dont wanna risk all your private stuffs by doing that. SD cards are always better as portable. After all, they were made for that purpose!

Good luck and Good day!

As someone who's had bad luck with failing flash drives a few times, specially ones which were crucial to work, can really understand how frustrating it can be of you're stuck with a bad disk.

Before going further, based on my own experience, I'd say given chance that the drive could be failing, it's advisable not do anything that might write on the drive. Any OEM or vendor tests or repair utilities, are likely to cause more harm than fix things back up. This obviously, is if you've data on there you'd not want to lose. Second step from here would be looking for VID captured through SMART to ascertain exact manufacturer, this could be important consider the flash storage within the card is from a vendor other than the company that sells the card. Depending on how much, possible data loss, could cost, you could consider getting professional services specially if the device your disk was tied to is enterprise managed. If not so, then cost of recovery could be several (hundred) times more than cost of the disk.

Using software available online, even ones which are paid, could offer only a brute force level hit and trial data recovery, with their very limited functionality. Most, even ones such as icare or easus have mostly been built around standard SATA drives, which are far more notorious with retaining data after several rewrite cycles. Even SMART is still largely in the ide/sata domain. But if your data isn't life or death crucial you could give it a shot. On lucky days I've recovered entire partition with tools as basic as Recuva, though of course after the format has been fixed.

Fixing the raw error ideally should get dealt with by the wonder tool Rufus, but as you obviously would have figured it that would happen at cost of data loss. Though Rufus can be counted on last ditch efforts to salvage the disk by fixing bad sectors. Being available across platforms I've found it to be my GO TO tool for all things related to flash drives, specially when I have to try a new distro or mount an old one out of the blue. The only catch I can think of is the disk not being read via USB adapter, which I've found getting fixed with using a standard SD adapter and connecting via MTP.

The ideal flow of data recovery: copy image, mount as virtual partition, followed by Sector level scan for recoverable fragments is going to depend on your disk not having physical failure, as the last user pointed out too. In which case, it would be a case of coat vs risk assessment. Most vendors are happy to return the disk or give a replacement, but that being the worst case scenario, so perhaps it would boil down to deciding between bearing cost of a new memory card or risking compromising private data, that should be the clincher. And the experience and the knowledge gained in the experience as the silver lining.

TL;DR: buy a new one in favor of safeguards personal data, be severely critical of Manufacturer, seller, Amazon et al and get a free replacement without return citing privacy issues by giving hell to the call center kid
OR format to a readable version with chance of permanent data loss by Googling for RAW error fix, and torrenting a suitable program for 'evaluation' and get done with it.

Fix Corrupted RAW Samsung EVO 32GB card

While formatting the Windows system, if your Samsung EVO 32GB card corrupted then do not worry, just try some easy ways to fix raw SD card and recover data from your raw SD card. First of all, I think you try use the Disk Management Tool which is an inbuilt tool present in Windows system. Also, you try to use CHKDSK command. After trying these ways, you can try to ix corrupted raw SD card and then recover the data from SD card.
