I have a ST1000DM003-1CH162 drive (4K physical blocks, 512B logical = "Advanced Format"):
Code:
ata2.00: ATA-9: ST1000DM003-1CH162, CC47, max UDMA/133
ata2.00: 1953525168 sectors, multi 16: LBA48 NCQ (depth 0/32)
sd 1:0:0:0: [sdb] 1953525168 512-byte logical blocks: (1.00 TB/932 GiB)
sd 1:0:0:0: [sdb] 4096-byte physical blocks
It apparently has the partial access problem - I can read the first 15GB (with one bad sector at 3.2GB) but nothing after that:
Code:
# dd if=/dev/sdb of=/dev/null bs=1M status=progress conv=noerror
3216535552 bytes (3.2 GB, 3.0 GiB) copied, 25 s, 129 MB/s
dd: error reading '/dev/sdb': Input/output error
3067+1 records in
3067+1 records out
3216535552 bytes (3.2 GB, 3.0 GiB) copied, 28.7733 s, 112 MB/s
15072272384 bytes (15 GB, 14 GiB) copied, 108 s, 139 MB/s
dd: error reading '/dev/sdb': Input/output error
14373+2 records in
14373+2 records out
This is the lone bad sector:
Code:
I/O error, dev sdb, sector 6282296 op 0x0:(READ) flags 0x80700 phys_seg 18 prio class 2
and this is the first unreadable sector due to partial access problem:
Code:
I/O error, dev sdb, sector 29439000 op 0x0:(READ) flags 0x0 phys_seg 1 prio class 2
Corresponding messages from terminal:

LBA 147D6Ch = 1342828d. I wonder how does that relate to LBA number 6282296 as seen from ATA.
Code:
ProcessRWError -Read- at LBA 000040A868 Sense Code=40000087

Same here: LBA 40A868h = 4237416d but it's 29439000 as seen from the ATA side.

The list contains LBA 40A868 which is the first inaccessible sector! Can this entry be deleted somehow?
