USB Stick Recovery Aberdeen

The dissertation. The payroll run. The only copy of a drawing set that took three weeks. All of this on a stick that either hit the edge of the desk or stopped somewhere in the middle of a copy. Small parcel work, which suits a region of long roads: an envelope posted from anywhere in Aberdeenshire today will be at the bench by tomorrow morning. Broken necks, dead controllers, deleted folders: all have a way back, and all ways back start with someone laying the stick down rather than looking for another socket.

Each and every single USB stick/flash drive job is diagnosed free. The fixed price reaches you in writing before any tools are used on your device.

In most cases you only pay if we recover your data. The exceptions are electronic/mechanical failures, chip level work, DVR and forensic jobs. All pricing information can be found on the data recovery cost page.

// twenty-five faults this bench knows cold

The twenty-five ways they quit

The first job on any USB stick / flash drive is to determine the cause of the problem by matching the symptoms to the fault. After twenty-odd years at this workbench, these twenty-five cover nearly every problem we've seen.

Snapped off at the plug

Leverage always wins, whether it's knees, a bag strap or a chair shoved in without looking. Where there is enough circuit board left intact, it will be rebuilt using a microscope. When there isn't enough circuit board left intact, we immediately move on to the memory.

Windows can hear it but cannot name it

It shows up when plugged in, then talks rubbish. This means that either the controller or its firmware failed, and none of your files have gone anywhere. Something just needs to talk for the memory again.

0MB, or a request to insert a disk

The controller woke up with no knowledge of how to address its own memory. We read the packages directly and recreate the mapping in our software, so that the controller can once again know where its memory exists.

An offer to format it

File table torn over good files. Refuse the prompt, remove the stick, get a quote first, and then post it to us exactly as it is. Anything written to it from now on will sit atop the files we would otherwise return to you.

Files deleted

It is still recoverable until the freed space gets claimed by something new, but just until then. It's much safer for that stick to go into a drawer rather than remain plugged into a port.

Warm to the touch, silent to the computer

Something inside has short-circuited; the stick is now burning itself out gradually. Remove it from the port immediately. Each additional minute connected to a live socket eats into whatever margin the memory has left (and nobody can put that back).

Joints cracked by flexing in the socket

If you leave a stick standing upright in a port for some time, it becomes a lever with a long arm and endless patience. The solder joints crack. Typically the memory packages do not even realise this occurred.

A one-piece monolith gone quiet

There is nothing on these which may be lifted off. Mapped test points are probed manually under magnification instead. This is a slower route, but produces identical files at the end of it.

Round the washing machine

Twice, in one memorable case. Provided they are dried and properly cleaned on a workbench, laundered sticks perform beyond their owners' expectations. However, plugging in a wet stick to see if it works is what ruins it.

Shortcut virus leftovers

After a spell in a shared machine, all the files on the stick appear as lookalike links. All of your true folder structures will almost always still exist under this illusion, intact and unscathed.

A terabyte printed on 16GB of flash

Classic marketplace item. When the real memory package reaches its maximum capacity, file writing folds back over the original contents. All content written before the fold can be carved out cleanly. All content after folding is never written down and therefore does not exist.

Cruzer Blades doing what Cruzer Blades do

There are two well-known types of failures on the SDCZ50. One is when the neck shears at the root of the plug. The other is when the capacity falls to zero without notice. Both have a standing routine here, and nobody is surprised by either failure.

DataTravelers gone catatonic

The Exodia DTX (and the previous model DT100 G3) will enter a controller state where it does not answer. Spending a whole day trying to get an Exodia DTX to respond to commands is pointless, so we go straight to the chip to address the memory directly.

Ultra Fits cooked where they sit

The SDCZ430 is designed to live permanently in a socket, but leaving it in a hot laptop port for three years isn't a great way to treat a piece of hardware. Eventually, the controller will fail, and monolith probing takes over the job.

Ultra Flairs shedding their jackets

Over time, the metal case of the SDCZ73 becomes loose and a track or two may come away with it. If this happens, we rework the board under a microscope first and then create a full image of the repaired stick.

Store 'n' Go worn out by office duty

Verbatim's "office staple" product would be used to move data between computers, but it ends up carrying live work instead, which it never had enough endurance for. After years of that writing it starts to decline gradually until it suddenly stops working.

Integral Couriers and Neons giving out

Grit can eventually find its way into the Courier's retractable slider, and the Neon just plain wears out. Far more often than not, if there is a problem, it is with the controller, not the memory, which is the good half of that news.

Verdigris across the contacts

Salt air off the North Sea, pocket damp and years of handling oxidise the contacts, and then the stick randomly appears and disappears. First, properly clean/dress the contacts, and then take one single continuous image instead of a dozen half-attempts.

Spiked through a front port

A storm, or a power supply going out, pushes a surge through a tower's front sockets, and whatever is plugged in takes the hit. Controller cremated (memory generally unharmed behind it).

Five years in a drawer

Old flash left in a drawer bleeds its charge away, so an old archive reads back weak. Image it slowly and allow time for ECC to do its job, and a great deal survives that would have been thrown out by one brisk pass.

Repaired into a folder of numbers

Clicking accept on the prompt given by the Windows repair tool generates a folder of numbered fragments with no filenames. These are completely ignored, and the real layout is rebuilt from a raw image of the memory.

The controller die cracked by leverage

Bending a stick far enough can crack the silicon inside while the board still looks straight and the solder looks fine. It will never enumerate again because the component responsible for enumeration is in pieces. Chip-off, then a software rebuild of the memory mapping.

Worn out as a boot stick

Running a live operating system from a stick, or rewriting an installer onto it every few months, is a workload a promotional flash drive wasn't made to support. First wear-levelling will fail and then entire sections of memory will cease to respond. Earlier writes will generally still be available.

Jammed into permanent write-protect

If a controller hits an error during a write operation it can flip its protection flag and remain in that state permanently. Each utility (disk management tool) that you run will report that the disk is write protected, and the many edits to the Windows registry found online change nothing, as the flag exists in the controller's own tables.

Wiped by a mass-production tool

The owner obtains the manufacturer's low level formatting tool (a "low level" format completely rebuilds the tables in the controller from scratch) with hopes of repairing an error. The low level format destroys all records of how files were laid out on the stick. The recovery process involves reassembling data using the raw memory; thus the function of this bench.

Snapped necks, and micro-soldering scoped honestly

The weakest link in all these "memory sticks", pen drives, thumb drives, whatever you call them, is always in the same place. The weakness lies at the joint of the metal connection and the thin circuit board. That will be broken when one knee presses against your laptop bag. Repair takes place with the aid of a stereo microscope. Where pads are torn they are rebuilt. Lifted copper tracks are repaired by adding bridges. A new connector is fitted. If the board itself cannot be salvaged then the NAND chips come off the stick (or card) and go onto an engineer's programmer. Thus, no part of the memory stick or card's own electronic circuits need to work again. Anyone looking for a microsoldering specialist Aberdeen can post to is seeking specifically: pad/track repairs on flash boards, ROM transplantations onto matched donor PCBs, chip-off reads from loose flash sticks/cards. This service does stop at this point and it is important to state the boundaries clearly. Flash storage soldered to a motherboard cannot be recovered here using micro-soldering techniques nor can it be recovered here using any other technique. Smartphones/tablets do also fall outside this service. Loose flash, yes. Any type of storage welded into a motherboard, no.

Controllers, and what they decide

A few different types of controllers can be found in most sticks: Phison, Silicon Motion, Alcor Micro, Chipsbank, Innostor, SMI. What type is contained within each drive is no trivial matter as the controller determines the page mapping method, error correction code (ECC) methodology and XOR patterns that will convert a raw dump to an actual file system. If this conversion is done incorrectly then you could have a perfectly good image of nothing. Most commonly used drives are just what most consumers purchase; examples include the SanDisk Cruzer Blade, Ultra Flair and ultra small Ultra Fit. Then there are the Kingston DataTraveler DT100 G3, the metal DTSE9 G2 and the newer Kyson. Additionally, there are the Samsung BAR Plus and FIT Plus, along with the Verbatim Store 'n' Go, Integral Courier, PNY Attaché, Lexar JumpDrive. There are monolithic style designs which contain both the controller and memory in one piece. Designs such as these require test points rather than a soldering iron. This work takes longer to complete compared to other methods, and the assessment will tell you if your drive contains a monolithic design well before you are asked to decide anything.

Deleted, infected, or dead one morning

Deleted the incorrect folder? Or came home from the print shop and found that every single document was shown as an icon for shortcuts? That second issue is a nuisance rather than a calamity; this type of contamination is going to hide far more than it is going to destroy. Deleting is essentially the same situation: the space will be flagged as empty, but nothing will be cleaned. So, the instruction is both uninteresting and very effective. Drawer. Disconnected. Leave alone. Here, a complete copy of the stick is made (end to end), and then the documents are cut from that copy. Never taken out of the originals. And sticks which just died in the morning without any fanfare whatsoever follow the same route, going directly to the chips.

// the kit behind the work

Engineering kit, not downloaded software and hope

Stick work is chip work throughout; therefore, each process performed with your stick (from booking it in to sending it home) takes place on the flash bench:

PC-3000 Flash

This software talks directly with memory packages and replicates all arithmetic operations that were previously performed by a dead controller. When a stick or card doesn't respond, work starts here again.

Chip-off station

The infrared and hot air profiles are tuned such that a memory package can be removed from a scrapped board with its stored charge undisturbed. The temperature control is the entire skill and rushing it will cost you your data.

Monolith spider-board adapters

Many cards store all of the data in one chip (slab) with no individual packages to remove. The test points have to be individually identified against pinouts and manually wired out. This process is slow. In fact, this is the only way to access and read the information contained within these cards.

NAND reconstruction suite

Until an actual raw dump returns as identifiable folders with their original date stamps, the XOR, ECC, and wear-levelling schemes are unpacked. Once this has been done ordinary arithmetic can be applied stubbornly until they turn into recognisable files.

Micro-soldering bench

Tracks torn off a board; pads lifted from a board; plugs sheared from a board; all can be rebuilt under magnification; also, if necessary, ROM chips can be transplanted into a new board if the existing board is beyond repair. Many dead sticks require only this service. However, this type of service does not extend to storage soldered onto a motherboard, as we do not take that type of work on.

Hardware write-blockers

Cards/sticks are accessed through a blocked interface. When your original memory leaves here it carries exactly the same data it had when it arrived.

What people actually carry in a jacket pocket

Many types of documents (payroll runs, site reports, inspection photos, dissertations, quotes etc.) exist in abundance on four models: Cruzer Blade, Ultra Flair, Exodia and Attaché. The majority of this documentation does not have a backup. Each one fails in its own typical way. The slim metal SanDisk bodies get extremely warm, and often work loose from their shells. At times an SDCZ50 will break at the neck, and other times report zero capacity on a given morning. Long budget Kingstons lever themselves against tight front ports until they eventually crack at the joint. A Store 'n' Go usually gets used as "live" storage until the wear levelling gives up. Couriers and Neons fill office drawers and will generally operate for many years past reasonable before the controller quits. Conference gifts are a gamble, and there's just one sound rule about these items: never store anything important on one device alone. All jobs done here are read at the chip level. Micro-soldering earns its keep in that, fixing torn tracks, lifted pads and sheared plug connections so that a stick can be read at all, as well as doing ROM transplants where a board is finished. It doesn't apply to storage soldered onto a motherboard, which is outside our service. Deciding which method best applies to your situation is part of the free diagnostic, and takes two working days once we receive your item.

// getting your device to us

Getting it to the bench — plainly done

Get a quote first by telephone or use our free online diagnostic. Most of what you see on this bench will then be delivered via tracked, insured post. This is one of the safest ways to move a failing drive and packages handed in at a North-East post office are normally delivered here the next working day.

Still attached to a laptop, desktop, MacBook, iMac, server or CCTV/DVR unit? Remove the hard drive or SSD first. The bare drive travels on its own; when removing disks from a server remove all the disks and label each disk by its bay. This lab does not take machines apart. Any storage that has been soldered onto a motherboard (as in T2 and Apple Silicon Macs and a couple of thin laptops) will not be worked on: if it will not unbolt, we cannot work on it. If you're not sure what type of machine you have, ring us first. Phones and tablets are also not taken on.

  • Place bubble wrap around the drive then place inside of a rigid box or padded envelope. Pack as tightly as possible so that there are no loose objects within the container. Leave all cables, caddies and power supplies behind except for when sending an individual external drive. When posting an individual external drive, send it whole, in its housing along with its own cable and power supply.
  • Print off the shipping & booking-in form (PDF). Write down your name, mobile number, and a brief description of what occurred. Place this document into the same package as the drive.
  • The Royal Mail Special Delivery service offers both tracking and insurance from door-to-door. Using your own courier service will achieve the same results.
  • Want to hand it over yourself instead? After receiving your quote, reception will accept drop-offs at the address below, Monday to Friday, 9am to 5:30pm, with no appointment needed.

// usb stick / flash drive recovery questions

Common questions

Seldom. Does the memory come back from the bend? It usually does. Most get put right at the connector, and where the board is beyond saving the chips can be read on their own. Get a quote first. Then send everything you've got. If possible take out the stub that was stuck in your laptop and send that too.
Because the file table tore and there is no longer a usable read map. That does not indicate anything about what is in the underlying files. Don't take the offer. Pull it out. Get a quote first, then post it or drop it off at our lab in Edinburgh, Monday to Friday, 9am to 5:30pm, no appointment required. Stacking formatting onto your existing problem creates an additional issue to investigate rather than just dealing with one.
Yes, so long as nothing has been written over that freed space. Each time the stick is plugged in somewhere new, the likelihood of recovery decreases a little bit; therefore the safe place for it in the meantime is a drawer. Then, after the free assessment, you will know specifically which files remain, prior to deciding to do anything else.
Nothing to look. Then there is just a single written number, to accept or decline. Deleted/corrupted files are counted as a form of logical recovery, where in most cases you only pay if we recover your data. A connector rebuild and/or chip-off read are forms of physical recovery: priced at levels higher than that band, and a 50% deposit is taken against your quote. Nothing ticks over in the background.
