Memories & SSD drives

  • All types of cards: CompactFlash, SD, MultiMedia, Memory Stick, xD Picture, SmartMedia,...
  • All types of SDD discs: the most common SerialATA (SATA) and other: IDE = ParallelIATA (PATA), USB, Serial attached SCSI (SAS), Fibra Channel,...
  • Memory cards and SDD discs use the same principle while storing and writing data
  • Data is recorded to memory, NAND chips. The only difference is in size/capacity and type of connection between the memory/SSD disc and the device it attaches to.
  • Internal or external discs from servers, desktop computers, laptops and other devices
  • All types of mechanical or electrical malfunctions

Types of possible malfunctions (which can help you determine what type of failure you are facing):

Logical - As well as with hard discs, these are some of the easiest and most common problems you can face. In that case, the memory by itself is ok but the information stored on it are not readable/recognizable although the space on the memory is occupied.
Your data may be lost due to viruses, malware and other unwanted software and/or due to formating, partitioning or repartitioning of the memory, other errors, deleted by mistake, errors in partition reading, etc.

Electrical - Damage to electrical components on the printed board (PCB=Printed Circuit Board) is very common after power failures/strikes (electrical shocks) or short circuits during inserting/removing of the USB memories, after which the BIOS or operating system does not recognize the memory anymore. These malfunctions can occur on all types of memories no matter its model, quality, size or production.
In such cases, data recovery is possible only if NAND chip which records and stores data is not damaged. In case of the damage tp control chip or some other electronic component on the printed board, data recovery is successful.

Mechanical - Тhe most serious and most complexed type of malfunction with the highest probability of data loss or unsuccessful recovery. It can lead to temporary or permanent loss of data stored on the memory if the NAND chip is physically damaged or broken. This can be caused by mechanical blows or physical destruction.

Most common causes of "data loss":

  • Errors within the electrical grid/power source, fluctuation/peaks of the power/voltage
  • Re-writing and/or deleting
  • Mechanical malfunction/damage
  • Accidents (fire, floods, etc.)
  • Computer viruses/malware
  • Human errors

Memory symptoms:

  • LED light is on but the memory is not detected
  • Reading/writing lasts too long (or even "forever")
  • Memory is "visible" on the computer but there are no data on it

SSD disc symptoms:

  • Errors within the operating system
  • Reading/Writing lasts too long (or even "forever")
  • BIOS and operating system can not ecognize the HDD
