Question about Toshiba MK4034GSX 40 GB SATA Hard Drive

2 Answers

For some reason it keeps disappearing from the hardware list when I open My Computer. It won't read any disk in this state. This has happened 4 times now and I can't seem to find a better driver for it. In the past, I have simply uninstalled it and restarted, and it's been recognized and restored to it's place, but this time it won't show up even though it shows in the hardware list in the device manager.

This can be either the controller having a problem or the drive. If you can put the drive in a differant computer and it behaves that would let you know if the problem is the motherboard or the drive.

If it is the drive the next time you get it working back up everything you want. The drive controller is intermittant so it may stop working pernanently. If it is the drive then you really don't want to trust it as a main drive or store anything that you don't want to lose. This is a small drive and you can get a much larger replacement for under $100. If you don't want to spend money you may find one for next to nothing or free just by asking around ie firends doing upgrades or computer shops.

If it is the motherboard then all you can do is switch to the other drive controller and boot using that one (if your bios allows this) or replace the motherboard.

Checked your RAM chips? Remove them and boot up and see if it will beep. If you have another DVD drive, swap it and try again. The board battery rarely goes, and only change it when it is not keeping the date/time etc, it won't help in outputting video.

If you if does not fix the problem they you could have a Windows/driver problem or a hardware problem. I would try to connect the drive to another port on your computer and/or try the drive in another computer. If it works then you may have a motherboard or Windows problem.

My External Hard Drive isn't working anymore, to say the just of it. It's on, lights on(not flashing, it flashes when it's being written to or accessed), usually has a regular clicking noise from it...

When a hard drive makes a clicking noise, this indicates the hard drive has failed and if the BIOS and the Computer Management does not detect it, then this confirm a hard disk failure.
To get the computer operating again, replace the hard disk, then install Windows on the hard disk using the Windows installation CD and the Windows product installation code that is on the label on the computer then install the device drivers and your programs.

Unknown device.

First what you need to do is go to the coby website and download the driver for your player and then follow these instrustion to force install the driver:
1. Look for the icon named "Computer" or "My Computer" and right click on it and select properties, this will open a window named "System Properties".
2. In the system properties windows click on the tab named "Hardware", and Select "Device Manager".
3. On this window you will see all the devices installed on your computer, look for the device not working properly (printer, dvd rom, keyboard, camera, mp3 player, etc), if there is a bigger problem, more likely you will see a cross by it, or an alert stating there is an issue with it.
4. Right click on the device you where having problems with and select uninstall, it will give you a confirmation, press OK
5. Once the device disappeared from the list, click on the menu bar icon that looks like a computer with a magnifying glass this will cause for the system to scan for any devices not registered and will force the re installation of the device.

Dvd740 not reading DVD+R disk

It sounds like the drive has failed but before you rip it out and trash it you should check that it is listed in your hardware via control panel , system. If it shows up as fine then try burn somthin simple like a regular CD not dvd. if that works the problem may be with your burning software.

if its not listed in hardware or has an exclamation mark by it the its time to open the computer case and check the connections to the drive. remove each connection one at a time and re-connect before moving onto the next one. switch the computer back on and see if it finds new hardware or shows up fine in your hardware list. If not then it is probably pooched.
