Remapped Bad sectors

October 10th, 2007, 10:38

Hi,

I vaguely understand how and why MHDD can remap bad sectors, but I have a question.
After I have remapped a bad sector, any further run of MHDD shows no bad sectors as does any other surface scan software.
Is there a way within MHDD to find out how many bad sectors have been remapped, or is there any software I could use, I would prefer a DOS/bootable piece of software than one within Windows.
Any help would be appreciated
Thanks
Ste

Check Reallocated sector count in Smart parameters use Victoria or MHDD .

Thanks for pointing me in the right direction.
Now I have another question.
I have a drive that I vaguely remember having to remap some bad sectors.
After using the SMART ATT command on the drive, I was given a list of information, with Name, Val, Worst, Raw
For Re-allocated Sector count, Val is 100, worst is 100, and Raw is 0
For Re-allocated Event Count Val is 100, worst is 100 and raw is 7
Which if either of these tells me if there are been any sectors allocated, also what do the Val, Worst and Raw Values mean. If there is a document that has information on these, a link would help :D, I had a quick look but couldn't see any.
Any help would be appreciated.

In short, the drive does not have any reallocated sectors (reallocation wasn't needed). This means that those bads were just soft-bads (like weak write and similar stuff).

I remembered doing a scan of MHDD previously on this drive which found several UNC errors, after which I ran a second scan with remap enabled and they were fixed, and subsequently didnt show up again.
Is this what is indicated by the Re-allocated Event Count Value 7 Raw?
