Windows 7: Data recovered but HDD corrupt, how delete files before sending to HP?

Data recovered but HDD corrupt, how delete files before sending to HP?

My HP Pavilion's HDD is under warranty & I have to send in the old drive. I want to delete sensitive text and data files. I mounted the drive as external to another Windows 7 laptop and used TestDisk to recover partitions and then recover my data, which I've already safely copied. TestDisk says that my System and Recovery partitions have bad MFT and MFT Mirror that can't be fixed. So I doubt I can access the files at all if I put the HDD back in the notebook, with a bad file system.

I want to delete the old user files in the C: partition and use CCleaner to write the space over with 0's and 1's. But Windows 7 in my new laptop can't "see" the C: drive - it shows 2 partitions on the external (Recovery & HP Tools), but 2 don't show up -- System and C: are hidden in a general "F:" disk. I can't access the drive/partition from Windows 7. I don't know why Recovery partition shows when it has corrupt MFT and C: won't show when it has good MFT.

The files can be individually listed within TestDisk application and a partition can be wiped but I don't want to screw up my warranty so need to just delete folders and files and then clean up. How can I do that?
Thanks.
(C and E are the new laptop; local disk F is the part of the external corrupt HDD that is not accessible but contains that HDD's System and C: partitions and G and H are on the external as well)

Hello Kwdall, and welcome to Seven Forums.

You might see if you may be able to use the "clean all" command on the HDD to wipe it out and do a secure delete on it.

Disk - Clean and Clean All with Diskpart Command

Hope this helps,
Shawn

Thanks to both of you, BUT, from another forum post here, it seems wiping the disk completely may void my warranty. HP has my credit card # and could then charge me for the new HDD they sent. So I want to selectively DELETE rather than wipe.

Why don't you give HP a call and clarify the situation. You do not want them to have your data.

Unless I misunderstood you, you already seem to have the choice of wiping select partitions rather than the entire disk - so you should be fine just wiping everything except the recovery partition. I don't think there would be a warranty issue with that.

Still, it's probably a good idea to call HP first as whs suggests.

I will try. I did call them and the particular rep I got said anything to do with the drive as an external was outside what they would discuss because outside of warranty coverage as a notebook drive. I'll try this specific question. They of course gave me the party line that it will be securely destroyed.

If you wipe it clean, I'm not aware of how they can tell if it was done inside or outside. I don't know how HP works, but I have had 2 Dell drives go out and was able to wipe them with the clean all command that Brink suggested. They never complained either time. Besides, If my personal info was on it, I would not send it back.

I just completed a Live Chat with HP and was given green light to wipe the drive and I have it in writing.

Smart to have it in writing.
