Bad Blocks solved by running Wn 10 CMD CHKDSK but loose data

Post by RedArrow »

Hi.
I have an AS3304T with 3 by 4tb drives in Raid 5 with an empty slot. I had Bad Sectors on slot 2 which showed as 2 Current Pending Sector (197) SMART info. A Bad Block Scan showed Bad Blocks so I replaced the disk. I did several things to the removed disk including running AOMEI bad sector scan and formatting the disk in NTFS and running a Command Line scan with the disk G:(chkdsk /f /r /x G:); both of which showed no errors. I put the disk into the spare AS3304T slot and it still showed bad sector but the SMART info was clear so I ran a Bad Block Scan and this now showed no Bad Blocks. The disk is now working fine as a single disk volume and has been filled to capacity as a test with reading the majority of the disk as well.

There was presumably a glitch in the disk but was cleared, presumably by command line relocating the Bad Block/Sector.

Is there no other way to recover a disk by relocating the bad block/sector like this except by going to Command Line CHKDSK scan in Win 10 which clears the data and obviously degrades the Raid 5.

Thanks
