Kioxia · Toshiba · Exceria · Exceria Plus · Exceria Pro · High Endurance · FlashAir · 2019 rename

Kioxia and Toshiba memory card recovery. The flash maker's own cards, under the old name and the new.

Toshiba invented NAND flash and sold cards under its own name for decades, and in 2019 its memory business became Kioxia and the cards followed; the two names are on the same lines, Exceria, Exceria Plus and Exceria Pro SD and microSD cards, and Exceria High Endurance cards for dashcams and home cameras, with Toshiba's name still on the older cards in bags and drawers and on the FlashAir cards, the SD cards with a Wi-Fi radio inside that sent photographs from the camera to a phone. Kioxia makes its own flash and the cards carry its own, which the recovery trade has documented along with the controllers it pairs them with, and a Kioxia microSD no reader sees is read through its test pads as routinely as any. The warranty, like every maker's, replaces the card. The faults are the common ones, and FlashAir adds one of its own: a card whose radio has stopped is still a card, and reads in any reader. A Kioxia or Toshiba card a reader still sees is £149 + VAT after the free look, fixed in writing; one no reader sees, or one snapped, locked or counterfeit, is £299 + VAT.

Take the card out and leave it out. Do not format it, however politely the computer or the camera asks. Do not run chkdsk, First Aid, a repair tool or a recovery program that offers to fix the card. Do not keep trying it in reader after reader, and do not put it back in the camera to see. A card that reads a little tonight may not read at all tomorrow; whatever is on it is recovered from an image, and the image comes first.

What tends to go wrong on Kioxia and Toshiba cards.

One maker, two namesA card marked Toshiba and a card marked Kioxia from the same line are the same card inside; the rename of 2019 changed the label. The bench reads the card's identity at the free look and matches it to the scheme that generation uses.
Kioxia's own flashKioxia makes the flash in its own cards, and the recovery trade's tools know its flash and the controllers it pairs with it. A card whose controller has stopped is read through its test pads, descrambled and rebuilt as routinely as any brand's.
FlashAirThe FlashAir cards put a Wi-Fi radio and a small web server inside an SD card so that a camera without wireless could send its photographs to a phone. The radio and the server can fail with age; the card beneath them is an ordinary SD card and reads in any reader. A FlashAir that no longer appears on the phone has not lost its photographs.
High EnduranceKioxia's endurance cards last longer in a dashcam's loop than ordinary ones, and they still wear out in the end, locking themselves read-only. They are read while they still read.

Packing it and posting it: take the card out of the device and leave it out; do not format, do not run a repair, and do not keep trying readers. Put the card in a small anti-static bag or a card case, tape that to a piece of card so it cannot shake loose, and post it in a padded envelope or a small box; a snapped microSD travels with every piece. Send the adapter or the reader only if the card has never worked without it. Use a tracked service and insure it for what the pictures are worth, and know that the posting address is not printed anywhere on this site; it arrives by email in reply to the form, with a booking sheet to print; the sheet inside the envelope is what matches it to your enquiry when it is opened. Or hand the envelope in at one of ten drop-off points, your name on the outside and the sheet inside. We pay the postage home either way. The whole of it is written up on the guide to packing and posting.

01

Logged the day it lands, and the first look costs nothing Free

A case number goes on the envelope and a number on the card the day it is opened, with both sides photographed. The card goes into a reader on a hardware imager that controls how long each read may take, never a laptop slot, and what it presents is read first: its capacity, its identity registers, its file system. That decides whether it is a card a reader can see with a fault in the data, or a card whose controller has stopped, and which band it falls in. The first look is free, and you can stop there owing nothing.

Nothing to pay for lookingA single figure, put in writingNo formats, no repairs, nothing written
02

Imaged, sector by sector, before anything else

A card that answers at all is imaged in full on hardware that limits every read and retries on its own terms, weak areas last, with a map kept of what could not be read. A card that is slow, that drops out, or that has locked itself read-only is imaged the same way, in short passes with the power cycled between them. Nothing is written to the card at any stage, and every later step happens on the image.

Sector by sector, weak areas lastNothing written to the card
03

The flash read through the test pads when the controller has stopped

A card no reader sees is a monolith job. The coating is removed to expose the internal test pads, the pinout is matched against a database or mapped by hand, a needle adapter is fitted, and the raw flash is read out around the dead controller. The scrambling, the error-correction layout and the page and block order are then solved in software, and a virtual image of the card assembled from the raw dump.

Pinout, needles, raw dumpDescrambled and reassembled in software
04

The file system rebuilt, or the files carved, on the image

On the image, the FAT or exFAT tables are rebuilt where they are damaged and read where they are not, deleted entries are brought back, and where the tables are gone the photographs and video are carved out by their own signatures. Video files cut short by a dead battery are rebuilt from a reference clip from the same camera. Every photograph is opened before it goes on the list; a file that will not open is not counted.

Tables rebuilt, or files carvedEvery file opened before it is listed
05

You see the file list before you pay

What was recovered is listed for you first, and only then does a bill exist. Approve the list and it is invoiced; turn it down and it is not, and where nothing has come back, most jobs carry no charge at all. The files go home on fresh media with the card, tracked, with the postage paid here, and your case stays open until you have opened them yourself.

From the bench

  • Say the line and the name on the card, Toshiba or Kioxia; it dates the card.
  • A FlashAir reads as a plain SD card. Put it in a reader before worrying about the radio.
  • Say what it served in.
  • The warranty replaces the card and does not touch the data. Claim it after the recovery, not before; the maker will not send the card back.
  • Say where the card was bought. The big names are the counterfeited ones, and a marketplace card under this label may not be this brand inside.
  • The free recovery software is a fair first step on a card that reads cleanly, and the wrong one on a card that does not.

One job, followed all the way through.

A Toshiba FlashAir W-04 32GB from an Olympus body, which stopped appearing on the owner's phone and was assumed dead, with a year of a retired engineer's bird photographs that had only ever been transferred by Wi-Fi

The card's radio had failed; the card itself read in a reader on the bench at full speed with its FAT32 volume intact. Nothing needed rebuilding. The photographs were copied out and every one opened, and the card went back with a note that a reader would do what the radio no longer could.

What helps, and what harms.

Do this much first

  • Take the card out and leave it out
  • Say no to every format and repair
  • Note the line, the capacity and where it was bought
  • Send it tracked; the first look is free

What sets us back

  • Formatting to get the device working again
  • Claiming the warranty before the data is off
  • Running the maker's format tool
  • Forcing a read-only lock off

Questions answered before you commit.

Is Kioxia the same as Toshiba?

Yes. Toshiba's memory business became Kioxia in 2019 and the cards kept their lines under the new name. A Toshiba-marked card is the same card inside.

My FlashAir card no longer connects to my phone. Are the photographs gone?

No. The radio has failed; the card beneath it is an ordinary SD card. Put it in a reader.

What does it cost?

£149 + VAT if a reader still sees the card after the free look; £299 + VAT if none does, or if it is snapped, locked or counterfeit. Fixed in writing.

Nothing gets worse while the card is out of the device.

Looking at it is free. Back comes a list of what opened and what did not, together with a single price to finish, set down in writing while you are still free to say no. On most jobs an invoice only follows the data. Until that list reaches you, leave the card in its bag and format nothing.
