SIM Card No longer Accessible
File Directory Damage
Files can also be lost if the directory structure has been damage.
You MUST STOP using the storage media that holds the lost files.
In this case you will need to send your Storage media to a
Data Recovery company so that they can use their specialised Software/hardware needed to recompile the directory structure to allow for DATA Recovery.
Access to files can be lost if the Storage Media has suffered a soldered joint failure "most common"and becomes invisible to the device it is attached to.
You MUST STOP trying to use the device as you could be making things worse and cause damage to the faulty device to the point of the DATA being totally unrecoverable.
The Faulty media will need to be sent to a Data recovery Company to see if the Fault can be fixed or bypassed to allow for DATA Recovery.
Severely Damaged Storage Media
Files Access Will be lost if the Storage Media has been badly damaged and can not be physically attached connected or inserted as it would normally be.
You will need to send the Damaged Media to a
Data Recovery Company so that we can examine the badly damaged media to see what is needed to correct the faults or bypass them to allow the specialised Software- -hardware to be used to extract your Lost Data, from the Damaged Storage Media.
Also the cost of Data recovery will be Higher if the faulty media has been opened before it is sent to us.
Access to files can be lost if the Storage Media has suffered Internal physical damage to the hardware and it becomes unresponsive.
STOP trying to use the storage media NOW. If the storage device is a Hard Drive there could be damage to the reading heads and you will need to send the media to a Data Recovery company so that they can examine it to see if they can replace the heads with identical donor parts to make possible Data Recovery from the faulty Media.
Recovering Lost Files
From a Faulty SIM Card
There are several ways that files can become inaccessible to the user.
If the files have been automatically sent to the wast bin then the user can get them undeleted. But if the files are no longer in the Bin, and there was no auto save or backup on the system Then the user could use a undelete software to recover the lost files.
"BUT" If the files are Vital YOU MUST STOP using the Storage Media that Holds the Deleted Files "NOW"
Because The space that holds the lost Files Will be overwritten With new data by the operating system,if you keep using the device that the storage media is on, and when that happens the Files will be lost forever.
You will need to send the storage media to a
Data Recovery company to safely recover your files.
