I have a 1 TB HDD so I want to test for bad sectors or bad blocks but badblocks takes a LOT of time in Linux (barely 4.66% done in 6 hours 3 minutes). In Windows however chkdsk scans in a few seconds and it couldn't find any errors.
What is the difference between bad sectors and bad blocks? Also, what is the difference between chkdsk in Windows and badblocks in Linux when it comes to testing bad sectors?
Answer
The short answer is NO, there is no free candy.
Obviously the reason why chkdsk runs so fast is because it doesn't check for bad sectors by default. You have to run it with /r switch to scan for bad sectors, at which point it will get slow as well.
As for the difference between badblocks and chkdsk, the first one is a dedicated tool which discovers bad sectors, while the latter is a general-purpose disk check utility shipped with Windows which happens to have the bad sector recovery feature.
