just got this program as a free giveaway and i wish i had something like this a few weeks ago when my main hard drive was about to go in to meltdown but good news i got a nice new laptop and managed to save a lot of my music 4 t/b and main games 3 T/B but i have just ran this program on my old pc and it picked up in a few minutes what was wrong so great news and it is now running full check as i have 10 T/B of hard drives it will talk a long while but i am sure it will be worth it
MANY THANKS

Très bon logiciel pour scanner le disque dur.
MERCI.What does this program do with SSD?
Does this actually repair or lock out the bad sectors it finds, or just shows you the problem then does nothing about it?
The reviews on the main page are pretty brutal about its value considering the many upvotes its gotten there…

I myself do not like the way S.O.S. does those reviews. If you notice they are 1-2 years old and, more than likely as is most software, this software is the latest edition with improvements.
Macrorit is usually really good HDD/SSD software, so Im downloading it and gonna run it through its paces on a SSD.[@DJ]
Just to add, it looks as thou it marks the bad sectors, for isolation by the operator.[@DJ] Where do you see that it marks bad sectors? The descriptions here and on Macrorit’s web pages only say it “marks them in red”, presumably on the status display, so you can see where they are graphically. “Red” would mean nothing to the operation system or disk controller. The “chkdsk /f” command in Windows (command prompt as admin) looks like it will search for bad sectors AND flag them to prevent future use. “chkdsk /r” does that plus it attempts to recover any data from the bad sectors.
So Macrorit’s program is good if you want a nice display or want to see IF you have bad sectors, and don’t want to fix anything, or if you want to manually do something about any bad sectors found. A comment in another forum (sorry, I don’t remember which one) said it takes a LOT of work to manually block out sectors by creating partitions of good and bad areas. Then you have a bunch of new drive letters and a drive that is failing anyway. Much better to replace the drive if there are many bad sectors. Also, the disk controller should automatically map out bad sectors, replacing them with good sectors from a reserved pool of sectors, so if you see bad sectors at all, it may mean that pool is used up and drive is failing. To check this, look for a tool from your drive manufacturer to read the SMART data the controller writes to the disk.

I don’t know of an application which will do what you’d appear to like Disk Scanner Pro+ to do (force the disk to allocate replacement sectors to replace any unreadable ones without affecting – e.g., wiping – the surrounding data). This is likely because lacking detailed knowledge of the way the file system is using the damaged sectors simply revectoring them elsewhere would leave any files (or, worse, any file system metadata) that had used them corrupted because the file system didn’t know the sectors no longer contained what they should and/or because the user might want to use an application like Unstoppable Copier to make a more thorough attempt to reclaim any missing data than the disk and/or operating system did.
When a 2 TB disk of mine developed some unreadable sectors several years ago I used a similar scanning facility in the free version of MiniTool Partition Wizard to find out where they were, deleted the partition which contained the corrupted area (and later placed a backup copy of the partition elsewhere on the disk), created a small new partition just large enough (4 GB) to isolate them (just in case they were the result of head contact with the disk surface I preferred to keep the heads away from them), and have used the disk without problems ever since (those Samsung HD204UIs made in Korea are almost immortal).
[@Mr.Dave]
By the way, the reasons I gave above are likely also why the disk controller does not do what you suggested it should. What it DOES do is remap an unreadable or unwritable sector when the system attempts to WRITE to it, because in that case the new data is by definition valid and can safely be written to the revectored location.
[@– bill] Hard Disk Sentinal PRO will reallocate any data it finds on a bad or failing sector it scans to a seperate “good” sector on the disk… and then properly mark the failing sector on the hard drive as “BAD” so that Windows won’t ever try to write to the “BAD” marked sector again. And it does so without affecting any of the other data that’s on the disk / partition.
[@Drew]
Aside from a lengthy reply I made which may or may not show up, it looks as if HDS Pro introduced a mechanism in Version 5 which seems to use ‘long reads’ upon encountering bad sectors (sectors which will just return errors if normal reads are attempted) to access whatever may be in those dubious sectors and then write it back, causing the disk to revector the sector without leaving any clue for the user (or file system) that it may contain garbage. HDS might have made the danger of doing this more explicit, but at least provided a list of files which might thereby be corrupted (though doesn’t mention doing anything to alert the file system if it includes possibly corrupt file system metadata).
