content: Yesterday a collegue gave me her Windows XP laptop and asked me to backup the whole harddrive because she wants to migrate to a new laptop with Windows 10On her XP laptop I found three partitions, and I checked each of them for any badblock#1 NTFS 60GB: all ok#2 NTFS 50GB: all ok#3 NTFS 50GB: found several badblocksI wonder if there is a way to understand which file is affected by the badblock? Data is for sure corrupted there at the physical layer, but how to know about the filesystem layer?Sorry for the silly question.

content: I checked the three partitions with Linux, which reports a list of damaged sectors.But what I'd like to know if there is a way to know which file is mapped on that sectors.

content: Quote from: magic on July 18, 2020, 06:41:11 amThis didn't report anything. Can I assume there are no corrupted files?20 minutes ago I completely copied all the files in the damaged partition into an external harddrive.Again, no warning/error message.It's a bit weird, becasue the physical analysis of the harddrive reports more than 5000 damaged blocks.

content: Yes, try either the find or cp on some files you don't have permission to access or something like that, it will throw errors at you (the find invocation simply reads all files and prints them to /dev/null).If there were no errors, it must have worked. It seems that you / your friend were lucky and the bad blocks fell within some unused area.

content: Quote from: 0db on July 18, 2020, 08:29:43 pmmaybe once, the laptop got slight bump while write/read progress if its HDD. or psu problem if its SDD of just near the drive lifetimehttps://www.crucial.com/support/articles-faq-ssd/my-ssd-has-bad-sectorsQuote from: 0db on July 18, 2020, 08:29:43 pmreading your OP the total volume is 150GB, i thought its SDD. but if its HDD it must be really really old HDD. but still, the plates is a nice decorative mirror.Quote from: tunk on July 18, 2020, 08:56:09 pmif you have free time to spend... wiping the whole area takes time, not really an issue for 100GB+ data, for TB data/volume? only worth for some sensitive data imho like business/IP/government secret or sex/scandal/affair or self naked pictures. faster way is open it up, dismantle the disc plates and grind the surfaces (HDD). or simply smash with hammer or burn if its SDD.Quote from: magic on July 18, 2020, 09:18:16 pmif its HDD is new or less than 10 years, its probably still can function properly if bad sectors are marked. but if its SDD, its a sign of end of lifetime. if its new and power disruption occurs during operation resuting corrupted files or bad sectors, maybe reformat can fix it?for hardcorer who want to get closer to their data from SW/OS level...http://www.cse.scu.edu/~tschwarz/coen252_07Fall/Lectures/NTFS.htmlbut i think the structure only accessible from disk cloner file output, not directly from the drive/OS. fwiw.

It's something like 12 years ago!Quote from: Mechatrommer on July 19, 2020, 03:43:25 amThat's probably the cause, in my opinion. I mean, in real life, sooner or later it happens

content: Quote from: 0db on July 19, 2020, 10:24:42 amthats the age when PATA is still a common thing. recently i got one dated 2007 giving up. i have another one stripped from a DSO manufacturer's date 2003 thats still readable with lots of bad sectors, maybe it had see less working hours inside the DSO. that HDD is going to die soon anyway even without a bump, continue to use it is hoping for disaster. bin it, its useless except its disk plate is an unusually smooth and flat high quality steel alloy mirror (i keep lots of them still inside the damaged HDD compartments) and some fancy neomydium magnets that can hold a utility compartment or something and lid intact together.

content: Just for my curiosity, I tested a second old hard driveCode:Checking for bad blocks, From block 0 to 156290903Writing pattern 0xaa, Reading and comparing: done, all OKWriting pattern 0x55, Reading and comparing: done, all OKWriting pattern 0xff, Reading and comparing: done, all OKWriting pattern 0x00, Reading and comparing: ...block 137614712: not equal to pattern 0x00block 137614713: not equal to pattern 0x00block 137614714: not equal to pattern 0x00block 137614715: not equal to pattern 0x00block 137616756: not equal to pattern 0x00block 137616757: not equal to pattern 0x00block 137616758: not equal to pattern 0x00block 137616759: not equal to pattern 0x008 bad blocks found!Results are weird. The tests wrote different patterns 0xaa, 0x55, 0xff, 0x00 and compared reads.How can it be possible that patterns 0xaa, 0x55, 0xff do pass the test, but pattern 0x00 does not?0xaa = bx101010100x55 = bx010101010xff = bx111111110x00 = bx00000000Weird also that dd if=/dev/sdb of=/dev/null doesn't produce any warning in the dmesg of Linux.it seems we have a definition of "bad cluster" like a block that doesn't exactly keep the exact information you write, but something approximated.Basically hidden and silent corruption

goes as it should go, and the testing software fails as expected at the first try.Now it makes sense, and psychologically it is reassuring.Code:Checking for bad blocks, From block 0 to 156290903Writing pattern 0xaa, Reading and comparing: ...block 33649053: not equal to pattern 0xaaJust, there are many more badblocks. More than what reported on the previous computer.I am going to trash both these two piece of garbage, both hard drives (already wiped) and the old laptop.Just, it's amazing how electronic devices behave when they age.

content: Hard drives have moving parts. They are all going to fail, one day of another. Sometimes they go poof without warnings, SMART errors (if you look at those up regularly) or Windows CHKDSK messages. Always keep important files backed up regularly.For HDD surface test tools I recommend the one provided by your drive manufacturer (they all provide a free utility, just go at their websites) or HD Tune.
