SanDisk Flash Drive Not recognized Freezes - Is it repairable ? 

Bruh it's just Alex being Alex. He's just straight forward and don't really care much about feelings.

This him is better businessman. Two years ago him was a better person.

It just adds to the clutter around. Put as much detail as you can in the ticket and be done with it. However; I understand wanting to add notes. As a former mechanic it was cool having a note from the vehicle owner because you get the description of the problem from the person themselves rather than some service writer that's only half paying attention and pretending to be in a hurry and leaves out half the stuff or doesn't word it properly.

...maybe because he might lose time, he has to read both notes and compare since they can have different or additional information. From that point of view I can understand ;)

He can never loose the note if he has it stored in his system on the computer.

I noticed the same thing

I was about to say that too haha good thing I'm not posting also

That's not how leds work

Was going to say this.

Yeah I would say put it in a non conductive fluid or try thermal paste and a decent heat sink.

Like the idea

@@manickn6819 I think thermal pad + heat sink is enough to cool a removable drive

@@sihamhamda47 probably is. Forced cooling of the heat sink may or may not be necessary depending on the size.

my idea to

The controller does all power management and often fails

I use sandisk flare and yes it's very hot because it's very fast

definitely working on a virtual machine so that the system and its file contents are accessible at all times. i just assume by how the file explorer looks anyways-

@@austist he isnt working on virtual.

I mean they do have his info

I think win 10 devender is good enough

@@pavloss3119 its not always intentional, the customer's computer may have a rootkit on it that he's unaware of himself, have some mercy 😂

huh, what a vague description, use canned air, hold upsite down???????????? uhhhhhhh ok............

@@budgetking2591 Canned "air" is basically R134a refrigerant. When you hold it upright, it dispenses gas, when you hold it upside down, it dispenses liquid refrigerant which basically works as a freeze spray.

@@budgetking2591 Anyone who works with electronics in any capacity knows what he means. Although there is a first time for everything, for everyone, and hearing about canned air and its uses might be yours.

So you won't be buying anything that goes to a repair shop? You're not gonna buy anything cuz everything break at one point and that's normal Nothing in this video stated that it died prematurely or anything like that

All flash drives can fail. Do not use them as your main drive. Do REGULAR backups of your critical files

Basically all flash drives are terrible for random catastrophic failures. Especially if you leave them plugged in. They overheat easily and will lose everything on them. Only use them for transporting files or as a backup (of a backup, preferably), or some other task where data loss is acceptable.

These devices seem to fail often but only because they are so popular... buy a good brand and stay away from Chinese cheapo things

My first thought exactly. You could even quickly salvage some data by doing dd

@@crylune was that operator error or linux error.

Don't use flash for backups! It's not reliable!

That would not help at all. There's a short, not a data protocol problem

Don't use flash for backups! It's not reliable!

When I deal with these devices I have a old soldering iron and melt the plastic

no way sherlock

Doesn't help you in this case, as the handshake and power negotiation fails. Usb 2.0 usually allows 100mA pre device negotiation and 500mA if successful, that is important. If a device has problems and fails the handshake due to electrical problems, it is auto setback. That is the reason why you get an infinite device detect, device not recognized loop. If the defect on a usb device is heavy enough or the handshake loop has been retried one to many times, it could happen that the used usb ports power polymere fuse goes open and you can't retry a connection for quite some time. Anyway, if the device is not stably connected to host system, no software will be able to reach through the memory controller down to the nand or nor chip itself. This is probably a case of a defective memory controller. Only data forensics whith grinding down the storage, hooking it to a donor controller or some hidden spi pins and hoping it does not scramble the contents will yield a possible success.

Nope You can hear the beep detection then a second after it get unpluged

Recovery software wouldn't work in this case because the chip is getting hot.

@Vlado T but if the chip is shorted inside it will not work.

There is a short inside the Chip, i have the same problem with a Sandisc usb drive. When the ice melt, what your cooling spray generate, u get another short of all usb pins.

The heat is not the problem. The heat is a symptom.

@@toolsarecool this drive don't make light (i have one),and the one in the bluetooth reciver have no voltage drop.

after some searching, i think you're right on this one but i don't understand the point of having a led here because the light is blocked by the houssing. i just have a small magnifier and it's difficult to see so clearly what is the component in the bluetooth reciver.

My conclusion after watching this channel. If there is heat on a spot, then it's most likely due to short I could be wrong but cooling is most likely not the answer

just pore IPA over it or Aceton.

Turn off autorun. But there could still be a firmware-based attack.

Don't use flash for backups! It's not reliable!

@@mrtechie6810 Nonsense. It's as reliable as any other electronic component. What are you using for backup, floppy disks?

He doesn't have PC3000 - not a data recovery specialist, just having a go.

The problems start when you start using them because they just aren't very reliable (all brands, as far as I'm concerned).

I'm more interested on Fix percentage for devices that hasn't and has been tampered, either total or per week or per month Maybe we can quantify something interesting like for example Alex's success drops (by how many %) for tampered devices.

he often says 50/50 for most things.

exactly what I was thinking

This is the first time i hear such a technique. can it really work?

I dont think so the instant when you pluged it in it get hot imediately because of the short inside

Those Sandisk drives are total crap it seems. I have one and it has never worked properly. Slow as hell and fails to detect occasionally.

@@generalbutz8477 Things generally work better in the cold. I have tried this on other devices and it works.

Ultrasonically welded I think

LED is flashing and working fine.

@@NorthridgeFix it would be just a test if this LED is having a too high internal energie consumption by a defect.

@@pidhsome i don't think so, he is a person like me everytime interested in the solution for a problem. during the long time he is fixing stuff he has adapted many things from the comments of his videos, like the use of fixing damaged pads with strips instead of using wires for everything. he is watching at the comments and trying stuff mentiond here often because he is a real technician.

@@pidhsome why exactly do you care? He clearly states there is a no fix fee in his terms and conditions. People either accept that or take their services elsewhere. He's entitled to charge for his time in investigating a problem regardless of whether he fixes it or not.

@@pidhsome ignorant

Did you watch the entire video. Thermal camera shows overheating chip

It is disconnecting as soon as it was connecting no way he would have been able to see it in disk manager.

if it appear in Device Manager as not recognized then it will not appear at all in disk manager...

Yep, I have a Kingston usb 3.1 with metal shell that gets super hot & can even burn your skin.

True that , mine overheats to the extent it lost the smd components on top . Any one has their values , please help

Are these surely glued, not welded?

@@elmariachi5133 I had to open the same drive yesterday with the same issues as in the video. From the outside it looks like it's 2 pieces but from the inside it looks like one solid piece. I had to cut it open as well.

@@Joey-ir3lk Thanks!

are they ultrasonic weld

@@jackiemay9471 idk man, I do electronics, not plastics 🤣 All I can say is that it looked like one solid piece from the inside and that cutting it open is probably the only way. But just like Alex said, let me know if you know a better way.

Nope, drive is dead. Just copy your files off and use something else, and keep backups.

Yeah

Of course he will. He has to make a living from something.

@@pidhsome its a business!! and the customer understands the costs involved before work begins
