Ok so my harddrive has decided to half break itself. I did try googling and got loads of product sales pages...


Basically the computer reads that the drive is connected and displays it in My Computer, but each time I try to access it it asks me to format the drive before it will open. Now I assume if I format the drive all the data links will be lost and that I'll then have to shell out for a recovery software option to restore them. I can't try connecting it to another computer as I don't have one - furthermore the data on the drive is larger than I've got spare backup space for so I can't do any fancy drive mirroring or anything.

And finally - yes its one-time copies of info on the drive - I've backups of much of the older stuff, but some of the newer isn't backed up so there is data on the drive I want to access.


Soo erm - help please :)
Is there any way to access it without formatting? Or have I got to get one of these software recovery programs (I should have some Sandisk restoration software around here which comes with their memory cards - though I'm unsure if that is suitable for harddrives).

It's an external hard drive, connected via USB?

Try a different cable and USB port. Mine did the same thing (it's a Maxtor). The cable carries power to the drive as well. In my case, I would get the error you have, but sometimes it would connect. Tried a new cable and it worked. If you use a different cable, make sure it's the type that can supply enough power to the drive as well.

Can you hear it spin when you plug it in?

Hmm the drive has its own mains power supply as well as the USB. I've tried changing to a different cable, and also pulled out both cables from the drive before putting them back in. I can hear the drive spinning up, but sadly the computer still wants to format it.

Try running chkdsk from the command prompt and see if it reads it. There is a /r and /f switch you can try to recover and fix errors, but just try chkdsk first to see if it's healthy.

What he said. There are normally two copies of the FAT (file allocation table) so that when / if one becomes corrupted it can be replaced with the other. Give CHKDSK a try.

If CHKDSK does not fix it, find a friend with a Mac. OSX reads fat files a bit differently. If it is NTFS then it will be read only but they should be able to copy the files you want onto another media. I would do this as the last resort but it is worth the try if nothing else works.

When you're done using it, do you just unplug it or do you right click it and select 'safely remove drive'? Sometimes stuff like this can happen if you remove it while it's still working. You should always right click it and safely remove it to ensure that whatever it is doing is done before you unplug it. Same goes for thumb drives and stuff like that.
