Question: I ran Seagate’s tools on my hard drive. ?It reports that there are errors and gives the LBA numbers. ?I would like to move the data at these locations to other locations on the drive. ?
How do I find out what files the data at those LBAs belong to?
The disk is 1TB, using NTFS.I’m running Windows 7, 64-bit platform.The drive is connected internally via SATA interface. ?
Due to the size of the drive, I’m having problems finding resources to back it up; so I only want to move the files that are in danger (i.e. residing on the bad LBAs).
Answer: If by LBA you mean the logical sectors:
Convert them to filesystem clusters (e.g. my system has 8 sectors per cluster):
C:>fsutil fsinfo ntfsinfo c:…Bytes Per Sector ?: ?512Bytes Per Cluster : ?4096…C:>set/a 13091568 / (4096 / 512)1636446
Use fsutil volume querycluster:
C:>fsutil volume querycluster c: 1636446Cluster 0x000000000018f85e used by —-D UsersMantasexample.txt::$DATA
Optionally, verify using fsutil file queryextents or fsutil volume filelayout, both of which will show the complete start�Cend ranges of that file.
