My SD Card is not being recognised by my Linux machine nor my Android phone. I also tested different SD card readers and the laptop internal.
In disk manager it shows device with an Unknown volume.
Last time I used it was on this very Linux laptop. I pulled it out after the light on the reader went out and the laptop was sleeping.
What should I do, it would be a tragedy to lose this data as I am not able to back it up all the time…
Honestly? SD card reliability is kinda garbage. Never rely on them, and always make sure you have a secondary copy or better yet, a full backup somewhere.
That said, try cleaning the connectors with alcohol, if you are lucky that is the ticket.
If the card is actually damaged, it’s a matter of how important data you have there, how much you are willing to spend to try to recover the data.
If the data is very important and you have a very big budget, then send the card to https://rossmanngroup.com, they also do data recovery from sd cards, but it won’t be cheap.
SDcards/microSD cards
$200 for basic data recovery, $900 for breakout board data recovery
Theoretically, it should be able to recover as much data as is still physically on the card, ignoring damaged lost places.
You can experiment yourself, but if the data is very important you can do more damage!
When you say the SD card isn’t recognized, do you mean the volume will not mount? Or do you mean the SD card doesn’t even show up as a block device? If the data is absolutely critical, and you’re not comfortable with the chance of losing it I would suggest letting a pro perform data recovery.
Otherwise, I’ve used and have had some luck with ddrescue in the past but I would highly suggest trying to make a block by block copy of the card just incase it is a hardware instability and not corruption that is causing the problem. Plus if it messes up, you’re not taking the chance of nuking the only copy you have.
Treat an SD card like an 8 inch floppy rolling down a stairwell. Your data may or may not be there.
I dump my camera cards and reformat, for example.
Specifically related to this, there’s a possibility it’ll randomly work for like an hour. If it does, get a tool called PhotoRec and dump the sucker. There’s a way to get filenames back from a PhotoRec dump but idr how. Look that up.
It would be something to mail it to Rossman, although he is in the US and I’m in Europe and I’d be more worried for the postage to lose it, as I’m still waiting for three packages that were sent last year in July.
Many of the suggestions were Windows, I don’t have any use of that, I think.
My issue is, last time I sent something to repair, they didn’t repair and broke my screen.
I’ll try some manual troubleshooting but it probably be a case for anyone in Europe that can handle it.
Also the SD Card is about 1 year old from purchase, I still have like unknown years old ones that work fine, slow but they serve their purpose. PNY 64GB, I have no idea why it says 69GB, looks like a troll wiped it.
Since Europe, look for a company near you, you will probably find something within the country.
Never send such parcels by regular mail, only courier companies, much better chance of delivery.
Be careful with this card if you do have very, very important data on it, trying to do it yourself can make things worse pretty quickly.
Theoretically, if it’s a damaged file system on the card, it should be repairable/recoverable, but if the card is physically damaged, you’re unlikely to do it yourself at home.
Most of the stuff is for windows because it represents the % of the market where the users are.
