Question about Memory Cards & USB Flash Drives

1 Answer

File system unrecognised by any of the operating system like windows and linux versions

I have a 4 G.B. Flash Disk usb which was working fine,but few days before when i inserted it to my PC it hanged my computer for a while and flashed a message to format the disk.Afterward it seems normal when it is being attached to the computer but while opening the drive it displays the message "please insert the disk into the drive" and in the property window of the disk it shows everything 0 bytes(used as well as free space).From my point of view may be the file system of the disk is being corrupted,please provide me a better solution.

Is this flash drive used souly at home, or do you take it and plug it into other computers? If that is the case, you may want to scan it, before opening it, cause you could be bringing home a virus.

Do i have to program this memory card 4gb


All you need to do is format the card and copy files to it. Windows typical filesystems
  • FAT
  • FAT16
  • FAT32
  • NTFS


Linux typical filesystems
  • ext2
  • ext3
  • ext4


Apple typical filesystems
  • HFS+


Windows really only see's it's own
Linux can see all of them
Apple can see all of them


So formatting in FAT32 or NTFS would be seen by any operating system

Every tym i insert my pendrive it says insert disk into the drive...???removable disk appears..but it doesnt opns...is there any solution...plz do help me


Assumption 1
Flash drive is damaged, the normal operating system.
Solution
If the flash drive is detected (eg; detected the flash drive in drive G), but it says "insert the disk into the drive ..."
1. Download software JetFlash Online Recovery (open link - select type software - select OS Windows - select language English - select product JetFlash All Series - Download).
2. Insert the flash drive
3. Open file OnLineRecovery.exe - Select the volume of the device - Repair the drive & keep data existed - START. If it fails, select Repair the drive & erase all data - START.

If the flash drive is not detected (not detected as drive G),
the above solution can not be used.

Assumption 2
Normal flash drive, the operating sytem is corrupt
Solution
Flash drives do not require drivers (plug and play). Because flash drives plug and play, it should be, when the flash drive inserted detects the operating system without installing drivers. But, if the operating system does not detect, the possibility of operating systems corupt. The cause is a virus corrupt your operating system.

1. Download and install anti-virus Avira or AVG (free).
2. Update anti-virus
3. Scan your computer.
4. Repair the operating system.
5. If no virus is detected, the possibility of operating system is corrupt.

I hope this information helps.

I've had some luck getting this to work again by using the linux ext2 format utility to format it back to the windows fat16 format, then use windows to format it again. There is something that windows doesn't like about the fat table when ext2 does it so you need to do this double format. Doesn't work all the time but does quite a bit.

TRY SOME OF THESE STEPS BEFORE YOU THROW IT

I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and OTHER devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems (mac/ Linux) similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especially true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

USB flash drives can fail for no apparent reason.
Sandisk Cruzers are especially bad for this.

USB hard drives should be treated with extreme care.
This is a real hard drive ! and knocks and bumps can quite literally kill them.

It is possible to remove drives from the enclosures in most cases and connect directly inside a PC to fully check it.

Note that if you hear a drive clicking or pinging this could be the worst thing you would hear.
Known as "The Click Of Death"

If none of the above steps help look at updating the drivers from the manufacturers web site in the support section.

I'm a little confused as you mention both Drive E. which suggests Windows and gnome which suggest linux.

WARNING: Formatting the disk will erase any data on it. Do not format the disk if you are trying to get the data off it that was on it yesterday.

It is possible that the partition table has been corrupted.

If you are using windows. You can either try right clicking on the drive (not double clicking) from Windows Explorer (My Computer) and clicking format. Choose the file system type and go. Alternatively, you could work through the disk management administrative tool. Right Click on My Computer -> Manage -> Disk Management. Right click on the volume and format it.

If you are using linux, see if you have a valid partition table using fdisk for the device. Then, after creating the partition, use mkdosfs to format the drive. If you have formatted the drive as a linux partition, such as ext2, ext3, or reiserfs, it is likely that Windows will not see it as a valid drive.

How to use flash drive


Cruzer Micro is an USB external memory where you can store files.
It is automatically detected and installed on all Windows OS from Windows 2000 onward, same on Mac OS and recent Linux versions.
All you have to do is plugging the device into USB.
After the flash drive had been automatically installed , it will be displayed under Computer as an external disk.
You can copy and transfer files using Cut, Copy and Paste functions, or Send to function in windows, or the file manager, depending on the OS used.
In Windows, before unplugging the memory from USB , it is better to turn off the computer or use the 'safely remove USB' function located near to the clock, on the lower right hand corner.
