![]() ![]() ![]() This is not problem / fault / limitation of the running application of course. So accessing the corresponding sector (or the file which saved on the sector) by any means may result in increasing weak sector count. For example if the drive does not receive enough power, then data recorded - but after some time, the drive may not able to read back. Generally any file operation (even a simple copy, move or system startup) can cause that new pending / weak sectors detected if the operating conditions of the disk drive is not stable. This is completely different attribute and reflects different kind of information. > and increasing the number of RAW read errors Read Error). Sorry for the possible confusion, but I can confirm that of course NOT the test (or a read operation) causes the problem with a sector: it just reveals the problem (the damaged sector) which may not yet known/detected and can otherwise (without the test) remain hidden for very long time (until the sector accessed, read or written). But any file operation targeting the affected sector would detect it. This is exactly the purpose of the complete disk scan: to REVEAL such problems which are ALREADY there on the disk surface, just not yet detected. This is completely normal and in some situations this is even expected. ![]() > sectors (parameter 197) can be increased when attempting to read The disk may be, for example, an unstable sector (but during scanning - the number of logical, unstable Hard Disk Sentinel does not focus on erasing free space but can erase complete drive by using the Disk menu -> Surface test -> Write test (or to perform industry / government standard erase, use the Reinitialise disk surface test). If you prefer to erase the free space - the easiest way is to begin filling the partitions with other files (ideally with zero contents). > unstable sectors are located without having to scan the entire large disk (TB). How to quickly and safely erase only the free space disk on which the This does not speed up the scanning, as this requires to perform complete scan, exactly to reveal such weak / pending sectors. > This will speed up the scanning of huge TB disks and fix problems more quickly with unstable sectors. Hard Disk Sentinel automatically shows this information, exactly to determine which partition, folder, file may suffer from damage. Not only the letter, but also the proper file, folder and position in the file. For example, in my case it will be L:\\ (365 GB) > Can the program determine what exact letter of the disk partition contains unstable sectors. Windows may notice and record problems in the event log (which can be also detected by Hard Disk Sentinel if you enable the Configuration -> Advanced options -> Monitor Windows Event Log for problems related to disks and storage.īut we have no details, information about the actual location, possible sector(s) which are damaged - unless we perform a complete scan. > W urządzeniu \Device\Harddisk2\DR2 wystąpił zły blok. I'm afraid without performing a complete scan, we have no information about the actual sector number(s) which require repairing. ![]() This is exactly what the Disk menu -> Surface test -> Disk Repair test does. Generally scanning the complete disk drive is the only proper way to reveal possible problems and detect the actual location of the sectors which are not readable - and then attempt to repair them. Do you have other ideas about how to detect and reveal problems - without scanning the drive? > issues with area having bad sectors is not only time consuming but cumbersome as well. Checking each sector on hard drive for bad (unstable) sectors and resolving the ![]()
