or use CHKDSK /F /R (i don't know if '/f/r' it's correct in my case ,please tell me which i should type in this case for best resultĤ. If using windows check disk tool ,should we use which way ?Ģ. (such as when we format the disk,is the marked bad sector still isolated/marked ? (not included new bad sectors appear after scanning) i read some similar topic and found HDAT2 and windows check disk tools ,but i'm not sure if them can isolate/mark the bad sector permanently is there anyway to know if the data is on the bad sector - when copying ,accessing ? (is there any error noticed ? )ģ. I wonder is it needed to isolate/mark the bad sector (without formatting/recreating partition the disk ), sothat we can protect the bad data copied/writed (in my case the reallocate sector count has not reached thresold, is it needed ?)Ģ. when i copying the data from this disk to other hdd , I want to use this hdd for a short time more (And to copy data to other disk ) ,and i have some problems which i'm not sure about ,please help :ġ. When i check with crystal disk info it notices me reallocate sector count (12/36)

(supports 28/48-bits LBA addressing modes)

resize ATA/SATA hard drives which supports SET MAX ADDRESS/EXT.

many different test-functions for hard drives.

test and repair device for bad sectors (so far version 4.5.3 only).With ASPI drivers you will get more information about SCSI devices other SCSI devices are detected via ASPI drivers only (must be loaded before).Wait for Windows 10/8 scan and repair the hard drive bad sectors. Review the scan result, then click Scan and repair drive. Vdetects SCSI hard drives via BIOS interrupt 13h or ASPI drivers Open This PC, right-click on System drive and choose Properties. detects USB devices via USB ASPI driver or BIOS (if supported).detects devices on AHCI and some RAID controllers.detects ATA/ATAPI/SATA devices with on-board and add-on controllers.device access with interrupt 13h, direct via ATA ports, with ASPI drivers.fully implemented commands: SET MAX, SET SECURITY, Device Configuration Overlay (DCO).check/remove (regenerates) bad sectors records, flags in FAT table. read/find/check items (MBR, boot, directories, etc.) of file system FAT12/16/32

you get much information about detected devices main function is testing and repair (to regenerate) bad sectors for detected devices You should make a DOS boot floppy disk or CD/DVD and boot your system for it and execute this program from that floppy disk or CD-ROM. It will not execute in a DOS session under Windows. HDAT2 is program for test or diagnostics of ATA/ATAPI/SATA, SSD and SCSI/USB devices.
