Hi i just tried plugging in my WD 500g Hard Drive when it just shows me the drive with no data. I ran a cksdsk/e and it says Invalid Parameters. It also asks me to format disk.

Can anyone help solve this problem?

You need to format the disk to use it... I'm assuming this is a new disk? – Not Kyle stop stalking me Jun 13 '12 at 16:58
That is not correct (assuming it came formatted which is almost always the case) – soandos Jun 13 '12 at 16:58
I've never seen a preformatted HDD before... How would they even decide what to format it as? – Not Kyle stop stalking me Jun 13 '12 at 17:10

This command will take a while, but try chkdsk I: /r /f /v /x where I: should be replaced with your drive letter.

hey they Soando, just curious i know you said it would take a while but any idea of how long. i have had it running for 6 hours now and it seems to be stuck in stage 4 not sure if it just takes a long time to go thru all the files or if it has froze. also what would happen if i prematurely unpluged the hard disk before it was finished? – Jon Jun 14 '12 at 1:06
ok so i wasn't able to finish yesterday. trying again today but now it says "the type of the file system is RAW. CHKDSK is not available for RAW drives. Do you know of anything else i can do? – Jon Jun 14 '12 at 15:35
At some point you messed up the formating on the drive (between today and yesterday). Now you have to forma – soandos Jun 14 '12 at 16:03
ok couldn't see your last msg lol. stopped at forma... but was looking around and saw something called "diskpart.exe clean" now it sounds to me like this will format my drive. which it looks like i need to do anyways my biggest concern is the photos i have on the drive. I do have Recuva which is suppose to recover data from formatted drives but have never used it before. any more pointers lol! thanks again for your help – Jon Jun 14 '12 at 16:27
