It crashed, and then i 'uncrashed' it by hitting it hard a couple of times, and now when i try to copy stuff onto it in disk mode, i get a crc error (cyclic redundancy check) and i cant write anything over about 1MB to it.

sounds like your hard drive is getting ready to crash when that starts to happen you see that alot on smaller hard drives 20 to 40 gig and not enough memory installed. the hard drive han only handle so much data. try starting off in sfe mode by hitting your f8 key bunch of times when your pc starts up, then click on safe mode then copy all your important data on to another external drive or disk, then do a full format of your pc.meaning wipe it and install windows again.now same goes with laptop but laptops have a little button on the mouse pad that easily hit by accident to stop your laptop mouse pad

It's time to purchase a replacement disk-drive, and then to install Windows Vista onto it, and then connect the "old" drive as a 'SLAVE' disk-drive, to see if you can copy any files onto the "new" disk-drive.
If by "restore" you mean that you are reinstalling Windows onto the disk-drive, to restore Windows to the "as-shipped-from-the-factory" condition, then a failure of that operation can be caused by either of three conditions:
* I/O errors reading files from the CD/DVD disks (due to dust/fingerprints on the bottom of the disks),
* I/O errors writing files to the disk-drive,
* an intermittent problem with the computer's motherboard or RAM, causing "random" failures when using the computer.
So, on another computer, take the CD/DVD disks, and try to copy the entire contents (namely up to 4.7 GB) onto the 'C:' drive, watching for any "I/O errors" during the file-copy operation.
If the file-copy completes successfully, then the copy of the files can be deleted.
If no errors occur, then it's time to suspect that the disk-drive itself is failing.
Buy a new disk-drive, and disconnect the old disk-drive, and connect the new disk-drive,
and restart the "restore" operation. If the "restore" fails on the new disk-drive,
then it's time to suspect that the motherboard has a problem.
However, an external hard-drive should _ONLY_ be used to make an _ADDITIONAL_ copy of your important files. It should _NOT_ be used to store the _ONLY_ copy of some files -- if/when the drive fails, the _ONLY_ copy of those files will be _GONE_. Not good!
Instead, it's time to purchase an additional "internal" disk-drive, which will be _NEWER_ and _LARGER_ and _WARRANTIED_ and to use software to "clone" your old hard-drive onto your new hard-drive.
Then, disconnect the old, out-of-warranty, disk-drive, and boot Windows from the new disk-drive.
Then, purchase an EMPTY disk-drive enclosure, for about $30,
install your old disk-drive into the enclosure, to build your own external storage device. Once you're satisfied that your new "clone" disk-drive is working 100% correctly, delete all the files from the OLD disk-drive, and then make a backup of your files onto the now-empty disk-drive.
It could be possible if the hard drive isnt too far gone, are you able to use it at all? have you tried to hook it up to a different laptop and see if you can access it from that? You'll probably be better off getting a list of anything that you can re-download and storing the irreplaceable stuff such as sensitive documents onto a disk. If you can do this then just reformat the hard disk and get it over with. You stand to be in for quite a headache trying to copy all your files off your hard disk and making sure all the files arent corrupted. This stands especially true if your hard disk has malware or a virus.
The disk-drive inside the casing has a probably-fatal problem.
Search online for a professional "Data Recovery Service";
ship them your disk-drive, they repair it, just long-enough to copy
all your files onto a brand-new disk-drive, or to burn to DVD-recordable media. Their services are _EXPENSIVE_ -- but "invaluable".
extremely difficult because of copy write protection. Requires special software and not all of it works all the time. Look for software on the internet. You will find some free programs to try. The illegal guys have made it hard for those who buy legitimate and just want to copy their own stuff.
Try using the boot disk to boot the system and then enter fdisk /mbr to fix the master boot record. It doesn't destroy any data on a computer.
There is a professional data recovery businesses that could probably recover that data - but at a cost. They are expensive and advertise in PC Magazines.
Take care because there could be a lot of rip-off merchants in this business.
In future, buy two hard drives ans use the free XXCopy from http://www.xxcopy.com/ to clone your system from one drive to the other.
A good way to back-up your system is to get a second hard disk of the same or greater capacity, and use the free XXCopy from http://www.xxcopy.com/ to make a clone of your system. If the BIOS allows it, you can then set the BIOS to boot to the alternative drive to run the cloned system, format the drive containing the defective system, clone the cloned system back to the main drive, set the BIOS to boot from the main drive, and you are back in business. You can keep the spare hard disk drive stored in a safe place ready to be reinstalled in an emergency, or to update the cloned system.
You install XXCopy according to the instructions that come with it. To clone the C: drive to a D: drive enter the following command in the Start => Run box
xxcopy c:\*.* d:\ /clone
It is as simple as that XXCopy will open a DOS window and clone the c: drive to the other drive specified in the command.
