Usually a sign of a dead card. There are now numerous pages about this on the web so it's unlikely there is any new ways to get what you didn't backup back short of recovery houses. But do try this in other PCs and especially ones that run Linux.

Once in a while a client/person will push back against this advice and all I can say is they are not helping themselves (in respect to trying and no backups.)

-> Face it folk. We only lose what we don't backup.



I've been facing this issue since today, whereby my TwinMOS Micro SD HC Card is not being detected by my Samsung phone, and when placed in the adapter and inserted on PC, again the latter is not detecting it at all, although in the Device Manager I can see my adapter being recognised.

I've tried Google, but the supposed methods shown, like using EaseUS Recovery software and others are not working in my case as am not able to see the card as a USB drive.

Any other methods to deal with this would be most welcome, as I have all photos and other important files on the Micro SD Card.

Thanks in advance.


Not knowing the generation or laptop/desktop configuriation, as has already been suggested above, the motherboard LED on(desktop)
would suggest that it is getting power yet the power supply may not be providing other needed voltages to start the system. Test the power supply. RAM is ususally a suspect but a beep code is common. Try swapping out or reseating the RAM one chip at a time - memory dance. Laptops may not be so obvious. Any connections you can reseat may help the situation. Remove the battey and plug it in to see if it boots. If it is a desktop - as stated above - take it apart and put it back together. Remove different components and see if that makes a difference. If it is an older PC it may have an overheating issue with solidified/inadequate thermal paste connection on the CPU. A non-working fan can fumble the boot.
If all else fails a defective motherboard is not usually a difficult fix. If you can get a POST that may give you more info.


Okay let's say:

SELECT username, password FROM Users WHERE Id=$id by
injecting the following-
Id value: $id=1 UNION ALL SELECT username, passsword
FROM Othertable

We will have the following query: -

SELECT username, password FROM Users WHERE Id=1
UNION ALL SELECT username, password FROM

Now what's the point of using UNION Query for the attacker since you don't know what is in Othertable ?


How to prevent Illegel/ Logically Incorrect Queries?

Illegal/Logically Incorrect Queries

3) Error message showed:
SELECT name FROM Employee WHERE id =8864\' from
the message error we can find out name of table and fields:
name; Employee; id. By the gained information attacker can
arrange more strict attacks

Should I hide the error message into 404 - Error instead of showing all of them? or is there any other method to prevent this?



I am trying to understand prepared statement and what it does.


"Prepared statements ensure that an attacker is not able to change the intent of a query, even if SQL commands are inserted by an attacker. In the safe example below, if an attacker were to enter the userID of tom' or '1'='1, the parameterized query would not be vulnerable and would instead look for a username which literally matched the entire string tom' or '1'='1. "

If an attacker input: userID of tom' or '1'='1

what will prepared statement detect as a userID?

userID: tom

Is that true? If all of them userID: tom' or '1'='1
then the SQLIA will be successful correct ?


The computer's death is generally the following three cases:
There is no response to the failure of the main board. Most of the main board after the power supply, even if there is no boot, the main board on the indicator light will rise, if not bright, first check whether it is a power connection or the problem of power itself. In particular, the motherboard 24Pin interface and CPU power supply line interface must be firmly inserted.
The main board lights but can not start. One of the situation is the main board light, indicating that the power has output, but still can not start, this need to check more things, but first did not enter the main board to start self inspection, it is possible to open the key and the BIOS problem.
Check the memory before the start and the beep. Normal boot players will hear a "drop", but if the sound of a buzzing or always "dropping..." is usually caused by a bad contact between the memory bar and the main board memory slot. As long as you rub it back and forth with the gold finger part, you can solve the problem. Of course, the memory slot on the motherboard is broken, which is also possible.


Reverend Jim is correct. It may help if you say the relationship out loud; if it's a 'has many' or 'belongs to' relationship (with a foreign key) you'd typically use a join:

  • A person has zero, one or many credit cards
  • A credit card belongs to a person

If it's a 'is very much like a' or a 'is a kind of' relationship, you probably want a set operation, like union, intersect or minus (aka except)

  • A debit card is very much like a credit card (ie. they both have numbers, expiry dates and security numbers)
  • A Visa is a kind of credit card

These aren't hard rules but a useful guideline.


They look highly suspicious to me. If that were on my computer I would

  1. export HKCU to a file
  2. take an image of the partition

Delete the keys and see if anything stops working. If it does and the things that stop working are legitimate you can import HKCU to get them back.

Have you tried Google Translate to see what the keys translate as?



One type of SQLIA is UNION Query and I still do not completely understand what is the point.

SELECT Name, Address FROM Users WHERE Id=$id by
injecting the following-
Id value: $id=1 UNION ALL SELECT creditCardNumber,1
FROM CreditCarTable.

We will have the following query: -
SELECT Name, Address FROM Users WHERE Id=1
UNION ALL SELECT creditCardNumber, 1 FROM

What is the point of uniting the sqlia with another table which values are being kept secret?

Are main point is to be able to login to the admin for example.


Hello Community,
I've been looking around my computers registry and have found a few weird keys under Computer\HKEY_CURRENT_USER\
The keys are:

I'll put them here too in case you want to copy and paste them or something:

Could anyone tell me what the heck these are about.
