Hard Drive Won't Format after Improper Shutdown.

It's not what you think based on the title. :)

(Running Windows 7 Home Premium)

I was in the middle of doing a full format of a new 1TB HDD using a SATA to USB adapter, when I stupidly hit he sleep button half way through.

I have tried everything to get the HDD to format since then and I just get errors.
I tried Wiping the drive with Active Kill Disk, but it just hangs up in the middle.
I re-initialized the drive. No change.
Used disk manager, didn't work.
I haven't been able to find a solution thru Google.

I don't know if this is meaningful info, but out of desperation, I tried cloning the drive which usually overwrites anything. The cloning software told me it could not start the clone since the "block sizes are different". The source HDD is 953,870MB and the messed up destination HDD is 953,877MB (7MB more). I checked every 1TB HDD I have, and they are all 953,870MB.

So that's the background. I have 2 questions:

1) Did I damage the HDD?

2) If not, is there something I haven't tried to get it operating properly?

Thanks very much. (sorry for the long post)

Try changing the format, maybe from NTFS to exFAT, before initiating the formatting.

Thank you both. I'll try these.

I wasn't aware of the Clean All command in Windows 7. Good to know.

Thank you! Can I diagnose a HDD connected thru a USB port?
