Re: semaphone time out period has expired

I don't think that has anything to do with the USB HDD. That is the name of a font or a software company!

It would be nearly impossible to find a 12GB hard drive today.

My Pleomax external hard drive stopped working on my MacBook (OS Maverick). It worked for one day and that was it. It flashes green and red when connected.

Probably not an issue with the MacBook but with the Pleomax drive. Be sure the drive is getting enough power to begin with. If it came with a 2 headed USB cable be sure to connect BOTH USB connectors to the Mac. You may also want to try the drive while your COMPUTER is plugged in and charging. Laptops and external drives don't always get along due to power differences and specifically laptops who do not want to waste their battery power on an external drive. If all else fails, try the drive on another computer just to make sure it is a drive problem and then contact the manufacturer for a repalcement drive.

Boot certificate expired.

Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup usually the delete or F2 key

Press and hold that key during the boot up process to enter BIOS using the arrow keys load failsafe defaults or load optimized defaults press escape then press f10 to save to cmos to restart if this fails to fix the problem

During the boot process tap the f8 button three times this will boot into safe mode where the only things working will be your mouse and keyboard enabling you to attempt to repair your computer

you could select the option start at last known configuration that worked this will tell what file has been corrupted or missing you might be able to work your way through problem if you are unable to find a solution

restart back into safe mode you might need to select your operating system to load into safe mode

click start control panel administration tools computer management in the left panel events + to expand then system you will see all errors in right panel right click select properties this will tell you what has occurred and the time it occurred

you might use the system restore to restore your system to an earlier time
click start all programs accessories system tools you should see your system restore option

hope this helps you

I have transcend 320 gB J25c external hardisk.I bought this recently.I pluged this to linux and window systems six or eight times and all of systems detect transcend disk.But the next day morning,I pluged...

Try checking your connections. Make sure the usb cable is firmly in the hard drive as well as the pc. Unplug the hard drive, restart the computer and plug it back in. If that does not work I would suggest trying some sort of file recovery/back up software and then calling in the warranty.

My kingston 8GB cannot open ( Message Show- The semaphore timeout period has expired) please help me. TQ

It sounds as if you have a faulty USB drive, depending on your Operating System, MS Windows / Linux, uninstall the USB drivers under device manager which could be found in the control panel on Windows XP/Vista/7, restart the computer and reinstall the driver's if they don't install back by themselves. But before you start try using your thumb drive on another computer. If you get the same problem, try to reformat the thumb drive, but before you do, be aware that all your information will be lost, and will not be able to be recovered without the appropriate recovery tools.

I have an 8GB Pleomax usb key and cannot access the files on it. My computer is not recognizing the usb.

I have the SAME problem, and SAMSUNG does NOT care ONE bit about helping customers. THE Only thing you can try is sending a REQUEST for HELP at Samsung Semiconductors

"Contact us"

THEY probably will NOT even respond... but hopefully Samsung will STOP selling their JUNK to US Consumers. FOR SURE do not waste another DIME on any SAMSUNG "junk" in the future. WE HAVE BOTH LEARNED OUR LESSON!!
You may look for a Samsung distributor in YOUR state at all US locations

BEST OF LUCK to Samsung customers. NOTHING WORKS and Samsung does NOT care!!

My external hard drive is not working. It makes a short, periodic buzzing sound and the power supply has a very high pitched but quiet ring to it... any thoughts?

If it still is under warranty, exercise the warranty, and get a replacement.
If the warranty has expired, disassemble the case, and extract the disk-drive. Connect that disk-drive as a "slave" disk-drive in some desktop computer, and see if the disk-drive is still functioning, and if the files on the disk-drive are still readable.

PLEOMAX 5GB Thumbdrive

Do you see a message on your system tray when it is plugged in? If you don't see any message, it means that the drive is not being detected. You can't retrieve any data or files on the thumb drive if it is not detected. Things you can try to isolate the problem:

1. Try a different USB port on your computer. Check if your thumb drive will be detected.

2. Try a different USB device like mouse on your USB port. If it is detected, it means that the problem is the thumb drive. If not, it means that the USB port is not working or is disabled.

3. Try the thumb drive on a different computer.

Hope this helps. ;-)

Pleomax problem

Try clicking on the icon in the taskbar and if it's like SanDisk flash drives there is a program you need to install from the Pleomax itself, that enables it and several tools as well. When you see that window, there will more than likely be an eject button as well.
