If you have problems with the file system on your Gmini you can try to fix it using the DOS utility, check disk (chkdsk).
Do the following;
? Make sure external AC adapter is powering the Gmini.
? Quit all running applications.
? Properly connect the Gmini to your computer
? Wait patiently (up to 5 minutes) for Windows XP to show the local drive as mounted.
? Open a DOS window. Programs > Accessories > Command Prompt.
? At the prompt, type chkdsk e: /f. Use e: or f: or whatever drive letter is representing your Gmini. The /f argument tells the program to automatically fix errors.
? Be patient, this may take a while.
? When it is finished, exit the DOS Window and properly disconnect the Gmini from your computer.
Try using the device now and see if makes any difference. If not you could try formatting it using a DOS prompt.

It's possible that your disk-drive is "failing", and it's about to "die".
Buy a new disk-drive, connect it, and try to install to it.
* bad RAM in your computer is messing-up the file-copy operations, and the CD-reading operations
* dying motherboard is malfunctioning,
* scratched Windows CD-ROM media
* malfunctioning CD-reader device.
Test the disc by using the command prompt to copy
Try to copy files from the disc to the hard disk.
If the hard disk cannot copy files, the disc might be damaged. If the
files are copied successfully, there may be file types on the disc that
the hard disk cannot read, or there may be a problem with the CD or DVD
To test the disc by using a command prompt to copy files,
follow these steps:
Create a test folder on the hard disk, and then give the folder
a folder name such as "cdtest." This is the folder to which you will
try to copy files.
and then click Run.
paste (or type) cmd in the Open box, and then press ENTER.
the files from the CD or DVD drive to the test folder on the hard disk.
To do this, type xcopy DiscDrive:\*.*
HardDiskDrive:\cdtest /v /e at the command prompt,
and then press ENTER. Make sure that you replace “cdtest” with the name
of your test folder.
Note In this step, DiscDrive is the drive
letter of the CD or DVD drive with which you have problems. HardDiskDrive
is the drive letter of the hard disk drive to which you want to copy
If you are asked whether cdtest specifies a
file name or a directory name, press F.
If you successfully
copied the files from the disc to the hard disk, the disc is not
damaged. To remove the copied files, type rd /s
cdtest at the command prompt, and then press ENTER.
cannot copy the files, the disc may be damaged. Contact the
manufacturer of the damaged disc to obtain a replacement.
best way to solve it and recover your data is to take it to the vendor else you can use dos to copy it to your pen drive...lets understand 1st why a vendor can only work with it because its a laptop and the hard disk can not be accessed externally like with a desktop...so dont play with your critical data hope this will help u a lot...
If your drive is making whining and clicking sounds, then you have a mechanically damaged drive which had what we called a 'head crash' due to the drop! If you can read/access the disk partitions/drives, I strongly suggest that you perform a full disk backup (with track error skipping) to another device. Also try a file by file copy to another drive (slow but you know exactly what is accessible). You may want to try to use 'Spinrite' (Google and read about it first) to attempt to repair some of the issues but unfortunately, a disk 'head crash' is usually fatal physical condition and data recovery requires specialized equipment and is VERY expensive! Hope it helps: let me know ho you go!
Unless the hard disk itself is damaged, data should be perfectly recoverable. This does not mean that any USB device will be able to read the unit. Some external attachments I found were not capable of reading large disks, or required those disks to be formatted while in the attachment, meaning that the disk addressing mode wasn't autodetected at all.
On the other hand, the disk MIGHT be damaged. Sorry to mention it but it's a possibility. Were those damaged IC on the board connected to the disk I/O system? (Or, maybe, the ICs only seemed to be damaged, but were actually working - it was the HD which was damaged all the time, and the system rebooted as soon as it tried to access the disk).
I'd suggest having the disk connected with a 2.5"-to-3.5" adapter to a Linux machine as secondary hard disk. This will allow direct talk to the disk unit, bypassing external devices and the like, and allowing direct access to the partition, with a much more informative error logging than Windows systems are generally equipped with.
What the computer is trying to tell you is that the hard drive has gone faulty somehow... hard Drives can and do spontaneously fail all the time..
It probably shut down because it detected a serious fault with the hard drive.
I think that at least you are going to have to try a new hard drive to see...
