I have a 40 (or 80) GB, USB, external, Toshiba hard drive that use for file back-up and to move files back and forth between work and home. The HHD model is MK4018GAP. I'm using Windows XP Media Edition on a Toshiba Satallite laptop that has always run perfectly. It's about 3 years old. The external drive may be 4-5 years old.
Last week it began cycling on very slowly. I was still getting the auto-prompt that you get when it cycles on, asking if I want to open the drive with such and such program.
This weekend the drive began screwing up. I no longer get the auto-prompt to open the drive, and I believe it's causing my laptop to hang-up. The light cycles from red (when you plug it in) to green, just as if would if were operating correctly. However, the drive doesn't show in "My Computer" as it always has.
Looking in the Device Manager, it shows as a "Mass Storage Drive" where it's always shown as a Toshiba MK4018GAP. In looking through the properties of the device, sometimes it's listed correctly, sometimes it's listed as a Mass Storage Device but I have no access to the files on the drive. As well, within the device manager on the device properties tab, sometimes it tells me the device is working properly and has a driver, other times it tells me there are no drivers installed.
I've done about everything I know how to do except swap out the USB cable. I was told, which is obviously wrong, that "they" don't make USB to USB connectors such as that which is on my external drive. I have two standards sized connectors, one on either end of the cable. Not sure of the defintion of "A" and "B" connectors, I assume the "B" is the little small USB connectiion with the hexagonal-shaped plug. I have two large USB connections on my drive, with no cages around the tongue of the USB connection. Nothing at Best Buy, nothing at Radio Shack. All they carry are the USB with the large connection at one end, and the smaller connection at the other end.
Also - when the drive is plugged in, sometimes it seems to be interfering with my celluar modem. At times, I cannot get my cell modem opening screen to come up. When I remove the USB HDD, the cell modem screen comes right up. The cell modem is also a USB device. I have no other USB devices plugged in, I have no yellow question marks or problems indicated in the device manager.
So - I'm at a loss, and I have 20-GB of law enforcement cases, 5 years of college work and pictures from my travels around the world that I cannot get off this HDD. I bought a new HDD today but I NEED the only to come up JUST ONCE so I can get my stuff off that drive.

Re: External Hard drive doesn't want to work
Have you tried a system restore incase some system files have become corrupted other the past couple of weeks.
If not try it first, Click on Start>all programs>accessories>system Tools>system restore and restore your system to a date and time when you know that your drive was being read with no problems. Once you choose the date and time, the computer will restore and reboot. The restore program will then reopen to tell you if the restore was succesful or not.
Once the screen has been displayed click okay and then plug your hard drive back in.
Hopefully this will help if not let me know by posting a comment.

Use MySafe to back up the files stored on the Ethernet Disk mini Home to
an attached USB storage device. This way, if files on the Ethernet Disk
mini are damaged or accidentally deleted, you can restore them to their
original locations. There are three main steps to using MySafe,Connecting an external USB hard drive,Backing up files to the external USB hard drive,Restoring files to the Ethernet Disk mini (if necessary) Before you can back up files, you need to connect a hard drive to your
Ethernet Disk mini via the USB port on the back. Use a hard drive that is USB 2.0 compatible. While connecting an external hard drive make sure your Ethernet Disk mini is turned on and connected to your network.Turn on the external USB hard drive.Connect the external hard drive's USB cable to the USB port on the back
of the Ethernet Disk mini, just like you would connect the external
hard drive to your computer.Confirm that the drive is
properly connected. Log in and click on the Administer HipServ link.
Click on USB External Storage under System. To back up files, navigate to the file or folder you want to back up to
the external hard drive and click on the disk icon in the "Backup"
column of the file list.When you back up files to MySafe, the
Ethernet Disk mini duplicates the file path in MySafe so that everything
you back up is organized in MySafe just as in its original location.
So, if you copy a file from MyLibrary, a MyLibrary folder will appear in
MySafe, with all folders leading to the backed up file.
Always click the Safely Remove Drive button on the USB External Storage
before unplugging your MySafe external hard drive. Wait for the
interface to change and for the Use Drive button to appear before
disconnecting the USB cable from the Ethernet Disk mini. Failure to safely remove your external hard drive before
disconnecting the USB cable can cause data loss and/or damage the drive.
Always use the Safely Remove Drive feature when disconnecting an
external hard drive.
It sounds as though your issue is one of in adequate power. Do both the external HDD have their own power source, or are they powered through USB? if they are powered through USB it may be that as soon as the second drive spins up to transfer the files, it overwhelms the limited power of the laptop. You can try it with the laptop plugged in (though this may not provide it with more power than the battery) or by purchasing a usb hub with its own external power source so that it is not drawing power from the laptop, or purchase an external hard drive with its own power source
The other option is simpler and free, and its to copy the files first to your laptops own HDD, then unplug the source external hard drive, and then plug in the drive you want to copy to, then transfer the files from your laptops hard drive. This will of course take twice as long, but will cost you nothing.
yes you could simply format the harddrive in Fat32 using your macos that would be the best solution but don`t forget to backup your data by copy pasting the files on your mac or something else and after that to move them on the external hdd again to be available on the windows machine
I think I know which limit you have hit then. The maximum size for any single file on a FAT32 system is 2^32-1 bytes which is 1 byte less than 4GB (binary version of the number, not decimal) or 4,294,967,295 bytes.
I would suggest you find a backup program to do all this for you. I use EZBackItUp (http://www.rdcomp.net/ezbackitup/) a nice freeware program that is easy to set up. Once the files are backed up, though, you should not delete them from your C: drive, as the program will them delete them from the backup too. What you should try to do is move big files (movies, music, etc) to the external drive, which will give you more space on your C: drive. And, as always, make sure you run a good cleaning program (http://www.ccleaner.com for a great one, download and install) to reclaim some disk space.
