SanDisk is the name on a huge share of the world’s flash storage — SD and microSD cards in cameras and phones, Cruzer and Ultra USB sticks, and the Extreme portable SSDs. Recovering flash is a specialist job quite unlike a hard drive, and one SanDisk product line has had well-publicised reliability trouble. Here’s what’s recoverable, and how.
SanDisk means flash: memory cards, USB sticks and portable SSDs. Card and USB recovery is often done at chip level, and the failed Extreme portable SSDs are an SSD recovery — send the whole unit.
SanDisk (now owned by Western Digital) is overwhelmingly a flash brand, which matters for recovery because flash behaves nothing like a spinning disk. The line-up covers SD and microSD cards — the Ultra and Extreme ranges in cameras, drones, dashcams and phones — Cruzer and Ultra USB sticks, and the Extreme and Extreme Pro portable SSDs. Each fails differently, and each is recovered differently, so it’s worth taking them in turn.
Modern memory cards and many USB sticks are monoliths: the controller and flash memory are fused into a single moulded block rather than separate components on a little board. That changes recovery entirely. When a card or stick is physically dead or not detected, there’s no board to repair — recovery is done by reading the flash memory directly and reconstructing the data using the controller’s logic, which is delicate, specialist work. If the card still mounts but reads as corrupt, software may carve the files off; if it’s dead, it’s a chip-level job. Either way it’s the same territory as recovering any corrupt memory card or formatted media. A card or USB stick is from £250 +VAT.
One SanDisk line deserves a straight word. Certain Extreme and Extreme Pro portable SSDs (from around 2023) suffered well-documented failures, with drives abruptly disconnecting and losing their contents — a genuinely widespread problem that made the news. If you own one that’s failed this way, you’re not alone and it’s not something you did. Recovery treats it as an SSD-level job: reading the flash and reassembling the data through the controller, with the same SSD caveats around TRIM and encryption. Because these are sealed, encrypted units, send the whole drive rather than trying to open it. A failed portable SSD is from £300 +VAT.
Flash recovery is genuinely possible even when a card or stick looks destroyed — snapped connectors, cards through the wash, sticks that aren’t detected at all — because the data lives in the flash chip, which often survives what wrecks the packaging. The work is done at the chip level and is precise, but the results are frequently good. A SanDisk card or USB stick is from £250 +VAT, and a failed Extreme portable SSD from £300 +VAT. As always there’s a free diagnostic and a fixed written quote up front, with no fix, no fee on most jobs — so a dead card full of irreplaceable photos is well worth having looked at before you write it off.
Often, yes, even when it looks destroyed. Modern cards and sticks are monoliths, with the controller and flash fused together, so a dead one is recovered by reading the flash chip directly and reconstructing the data, delicate but frequently successful. A card that reads as corrupt may be recovered with software. A card or USB stick is from 250 pounds plus VAT.
No, not if you need the files. A card asking to be formatted can often still be recovered, but formatting it wipes that chance. Set the card aside, do not keep reinserting it, and get it recovered, the files are frequently retrievable from a card that will not mount normally. Recovery is from 250 pounds plus VAT after a free diagnostic.
Possibly. Certain Extreme and Extreme Pro portable SSDs had a well-documented fault where they abruptly disconnected and lost data, so this is not something you did. Recovery treats it as an SSD-level job, reading the flash and reassembling the data. Send the whole sealed unit rather than opening it; a portable SSD is from 300 pounds plus VAT.
Frequently, yes. The data lives in the flash memory chip, which often survives what destroys the outer packaging, a snapped connector or water damage. Recovery is done at chip level by reading the flash directly. Do not try to dry and reuse it repeatedly; set it aside and send it in. A card or stick is from 250 pounds plus VAT.
A SanDisk SD card, microSD card or USB stick is from 250 pounds plus VAT, and a failed Extreme portable SSD is from 300 pounds plus VAT. The exact figure depends on the fault and is confirmed in a fixed written quote after a free diagnostic, with no fix, no fee on most jobs.
Dead card, snapped stick, or a failed Extreme SSD? Don’t format or keep reinserting it. Send it in — SSDs whole — and we’ll tell you what’s recoverable. Free diagnostic, fixed quote first.
