Failed external USB drive

r2015

linux live distro or systemrescuecd perhaps ?

I downloaded this and have it on a spare computer but have no idea how to use it to copy the disk, which it does seem to recognise.

As this poster hints at, heat is a BIG problem for external hard drives.

I presume that doesn't apply to SSD drives. Would a 128 GB USB drive be less likely to fail than a spinning HDD? I was considering this to use in a 3.0 port on a Chromebook, remarkable value at £22.95 delivered: https://www.mymemory.co.uk/USB-Flash-Drives/MyMemory/MyMemory-128GB-USB-3.0-Flash-Drive---Red

Good value, but don't store anything on it that you can't afford to lose.

If you are not familiar with using Linux then perhaps you may be better using Testdisk/Photorec under windows.

But if as you say it does seem to recognise the disk then you could then mount the said disk partition(s) and copy the data using the cp command to another disk. But the "seem to" is very vague

you could then mount the said disk partition(s) and copy the data using the cp command to another disk.

That is the part I don't understand.

That doesn't help if the hard drive cannot be read.

I understand that, if the drive is not seen in the BIOS, then that's one thing but you said it was, it may be parts are recoverable by direct access to the drive.


As I said think about the data content, if its critical to you, you may want to bit the bullet and get it professionally looked at, rather than risk damaging it as you try a home recovery.

SSD's can fail too. generally SSD's are more rugged as theres no moving parts, but often they are harder to recover data from in the event of a failure

Drives have two "blocks", the PC interface, and the bit that does the actual storage.

In a spinner, the interface and the storage are separate, if the electronics go its possible to swap the electronics with a exact like for like and recover. If the platter fails it can be dismantled, the damaged sections removed, or otherwise fixed (say smoothing over if its a scratched platter) and some data recovered. Both are possible, neither are cheap.

In a SSD the same two blocks exist, but they are typically integrated onto one circuit board. Its just as possible to transplant chips (interface or storage) but a lot harder due to component sizes.

Which is likely to fail, hard to say, I've had spinning drives last years and SSD's fail in months, like anything better quality control as you pay more tends to give a better quality, but even the best quality devices can and do fail.

[FONT=&quot]Such situation is extremely serious. [/FONT][FONT=&quot] I personally suggest you try some professional data recovery software like [FONT=&quot]xxxxxxxxxxxxxxxxxxxxxxxxx[/FONT] to see if it can read your drive and recover data for you. it is completely free, jus have a try. [/FONT]
