Hard Drive

I have 2 hard drives. Main as C: and 2ndary as D:
I use D: to store large files. Today when I tried to open D drive, I got a warning that says my D drive is not formatted . But it is formatted, and already has large amount of files in it. The hard drive is only a year old too.
What is happening to my D drive?
If there is no solution, I guess I can just format again and lose all files which I hope to avoid.
Please help me with your advise
Thanks for your time

Don't feel so bad I had to get a new power supply.

Are the 'C:' and 'D:' physically different disks, or just partitions on one physical disk?

In any case, I'd say the disk where 'D:' resides is failing. If it's Maxtor, I can just say that I'm not suprised

Get one of the diagnostic tools and run them:

Maxtor's PowerMax 4
Hitachi/IBM's Drive Fitness Tool
Seagate's Seatools
Samsung's shdiag
Western Digital's diagnosticproggy

There's a few, all manufacturers have their own, and I think I listed most, and they should point out if there are any physical damage (just need to download and run one, I'm only familiar with IBM's and Maxtor's tools tho)

this will at least give you a look at whatever is left and the chance of recovering it

Hi =)
Thanks for the advises.
It is two physically different disks.
And somehow, you guessed it correctly...it is from maxtor
Are maxtor hard drives known for this kind of problems? Your answer would help me greatly for my next hard drive purchase.
Unfortunately, I was not able to run the Maxtor's PowerMax 4 diagnostics tool, because my computer doesn't have an A: Drive(floppy drive)

Oh well...looks like I really have only one option left which I was hope not to do...recover whatever I can and reformat

Since I can't run diagnostic tools, I know it is hard to pinpoint the cause of this problem; but knowing that the hard drive is from maxtor, any close guesses(poor craftsmanship, compatibility issue or etc)?

Again, thanks everyone for great advises ^^

Ohh, well here's a CD rom version of the diagnostic proggy, should be able to use that. (If you have a CD-ROM burner )

And for the cause of the problem, probably poor craftmanship. One of my old-old HDDs died, and it was in kinda urgency so I got whatever disk I could get, and it was a Maxtor. Had 3 years warranty, and I joked about the disk lasting 1 year. After 13 months, the disk was broken. Replaced with Hitachi/IBM drive

I'm not sure of the current Maxtor drives, but there's some series of disks that won't last much longer than a year, bit like IBM's DeathStar line was few years ago.

Another excellent utility to check over your drives is HDTune. In fact, it's one I prefer over the majority of others. :P

Hi everyone =D
Thanks for great advises...it was very helpful.
Found out that my hardware is operational(fortunately not dead yet )....so something inside must be corrupted or something.

Again, thanks for all the advises and suggestions =D
Wish everyone the best ^^

You can post the results of HDTune if you like.
