I'm posting this as I believe there's still hope to recover my hard disk.
Currently I'm using a 120GB SSD as my OS. My old OS hard drive carked it, making me buy an SSD.
Anyways, the BIOS detects the hard drive it's a Seagate Momentus 500GB. No scrambled letters or numbers seems normal. But when I have the hard drive in as a secondary drive, Windows refused to start up or even set up when I was installing Windows 7. So I had to remove the hard drive while I was installing the SSD windows and even starting the pc after BIOS.
Anyway Once installed, I put the hard drive in a external hdd enclosure to see if that would help just so I could back it up. The hard drive is semi detectable. Coming up with the drive Letter but unclickable and says I need to format before I can use it.
Should I format it and then just try to scavenge what I desperately need or is there another solution?
Is this a SATA drive? If it is try different SATA cables, the cable could have gone bad. Also try a different sata port if one is available. If none of that works, try putting it back in the external case and run scandisk on it(right click the drive, select properties, click on tools tab, select "Check now").
If none of that works, drive could be bad. You could leave it in the external case and reformat it and see if it stabilizes out.
I should have elaborated more, it's for my laptop and is a Sata drive, so no Sata cables are nessecary. I tried clicking check now and it says "Disk check cannot be performed Windows cannot access the disk"
Well, if Windows can't access the disk it won't be able to format it either.
I assume you're connecting it to your laptop via USB? How did you connect the drive as a "secondary drive"?
If Windows can 'see' the drive but not access it, try using SeaTools to run a scan on the drive. You can try running the software from Windows with the drive connected to USB, but you may need to re-connect the hdd to your laptop's SATA and run SeaTools from a boot cd: www.seagate.com/gb/en/support/downloads/seatools/
Like DIsk Management Tools
Or Windows Lite Boot Cd
And Check For Hard Disk Errors And Try to Solve It..
May You'r Drive Cause By Virus.. Try To Scan With Emergency Disk..
There Are Many Emergency CD's Free By Antivirus Programs...
Scan With Emergency Cd's
And Check The Errors With Disk Management tools
"Disk check cannot be performed Windows cannot access the disk"
At this point you can't recover any data unless you send the drive to a data recovery service.
Does not necessarily mean the drive is dead however.
If the partition is corrupted this is windows' way of going home to cry to mama.
Go into Control Panel > Admin Tools > Computer Management > Storage > Disk Management
Right click your drive, delete volume(this will erase the drive!)
Let it do its thing.
Right click your drive, new volume, right click again format.
If you are successful creating a new volume, then the hard drive is ok.
