good day.!

I am having problem with my Hitachi HDD..Every time i format it, the format session will not complete because of bad sectors on it.Is there any other way to bypass/repair this bad sectors via a bootable dos base software or in any other way.?

Thank you for giving time.

As reports, the Hitachi disk fails partway through format and rightly pointed to filesystem checks. Filesystem tools can clear logical corruption but cannot reliably fix failing media. The next step is to determine whether those sectors are logical (fixable) or physical (sign of hardware failure).

Run a SMART inspection from a boot environment (Linux live USB or WinPE with smartmontools) and check Reallocated_Sector_Ct, Current_Pending_Sector and Offline_Uncorrectable. These attributes show whether the drive has remapped sectors or is awaiting remap. Example SMART query (from a Linux shell):

smartctl -a /dev/sdX

If data matters, make an image before any surface-writing test; writes can force remapping but also destroy recoverable data. A common cloning workflow uses GNU ddrescue to capture as much as possible before attempting repairs:

ddrescue -n /dev/sdX /path/to/image.img /path/to/rescue.log

For surface diagnostics and forced remapping, use manufacturer diagnostics first (Hitachi/HGST Drive Fitness Test) or well-known utilities such as MHDD, HDAT2, Victoria or Seagate SeaTools. Run non-destructive tests first; only use write/zero-fill passes if data is already secured and a remap is acceptable. If SMART counts increase, short/long self-tests fail, or surface tools report many unremappable sectors, the drive is failing and replacement is the safest option. If the drive is under warranty, arrange RMA rather than extended repairs.

Hello,

Try using chkdsk at command prompt. Try typing chkdsk volume:/r were volume is the drive letter, the /r should scan for bad sectors and fix them.

- Let us know how it goes.

I cant even use the cdrom to format it. I am using my usb stick(windows xp usb stick edition) for formatting. but it stops right there. If i use the chkdsk /r which would i start please..

I can boot any dos base software on my usb but i dont know whats the best dos base software to repair bad sectors.

Thnak you for your time & help guys
