"Diskpart clean" just puts zeros in first megabyte of physical drive.
Sometimes (not always) partitions are aligned to the MB border so not in that area. Don't know where win7 starts the first partition by default. My partition starts at block 63.... so is unrecoverable after "clean"

You PW screenshot showed a LBA start 2048 (first partition). So it starts at 2048*512 bytes=2048*0.5kB=1024kB=1MB

I think win7 starts partitions at 1MB boundary by default(?) In my case it has probably changed due to some partition resizing software.

once again... recovery software can rebuild partition tabel very easy. And refresh mbr code as well.
It doesn't touch the partitions themself!

But "diskpart clean" didn't clean the partition table/mbr code only (first 512 bytes on disk). It cleared the first MB. Luckily there was no partition there.

You could have recovered D and E anyway even in that situation!! And then use Macrium to restore.

But ALWAYS Backup! Human errors or software failures happen everyday

guys, Im having hard disk error warning from windows. Ran file system checks with PW on every partition, just had a 1 error and it was corrected. And now ran bios hard drive self test, and it came up with the SMART CHECK ERROR.

I saw what to do when i searched the forum, but my case is little different here cuz you guys know what happened exactly.

Is this due to recent recoveries or is my hard drive failing?
I have planned out to do a full hard drive wipe with a help of my friend's note for backup purposes.

So, should I worry or is this normal after such a rough ride to file systems im planing on delete all my partitions and do a full wipe clean and start from scratch of the scratch.

I wil post a screen shot below and tell me should I worry? And would rebuilding everything work?

EDIT : More info.

*ran check file system on PW in every partition. C and sys reserved didnt had any errors. D and E had 1 eror per each and corected.

*restarted. And so checked C.

*again checked 2 times per partition and 0 errors.
*ran windows check, no errors.

* but hard error message keep appearing, so ran from bios,
1. memory test and its ok, then
2. Hard drive self test - gave smart error. So now note isn't in use. i have shut down it.

why did you run file system check within PW? Normally you simply do:
chkdsk/f c:
from elevated command prompt. Anyway what kind error did it find? Now no more errors, so corrected?

added more info on privious comment.
I forgot chkdsk/f. I can't remembes what was the error exactly, as far as I thnk, it was just a bad sector found.

Now, no more errors in file system. But bios hard disk self test gave above picture.
Repeat, had restarted 2 times, C, D, E or sys reserved has no eror showing in PW or windows checking tool.

Ah, no, I didnt run it two times.
Isn't that red lines of text and numbers means any error??

Edit : I never had smart check error before. Not even in desktops. So im not sure how it looks. Thats the screen snap of bios hard drive test.

All abou SMART
S.M.A.R.T. - Wikipedia, the free encyclopedia.
Visibility to host systems
Depending on the type of interface being used, some S.M.A.R.T.-enabled motherboards and related software may not communicate with certain S.M.A.R.T.-capable drives. For example, few external drives connected via USB and Firewire correctly send S.M.A.R.T. data over those interfaces. With so many ways to connect a hard drive (SCSI, Fibre Channel, ATA, SATA, SAS, SSA, and so on), it is difficult to predict whether S.M.A.R.T. reports will function correctly in a given system.
Even with a hard drive and interface that implements the specification, the computer's operating system may not see the S.M.A.R.T. information because the drive and interface are encapsulated in a lower layer. For example, they may be part of a RAID subsystem in which the RAID controller sees the S.M.A.R.T.-capable drive, but the main computer sees only a logical volume generated by the RAID controller.
On the Windows platform, many programs designed to monitor and report S.M.A.R.T. information will function only under an administrator account. At present, S.M.A.R.T. is implemented individually by manufacturers, and while some aspects are standardized for compatibility, others are not.

BIOS can talk to the disk directly and asked to SMART firmware on harddrive... "What are the failure statistics" . You never did that before I assume? If not ... I do neither ... maybe this is the case a long time
