I have some trouble with my external USB 3.0 drive with 1Tb HDD. I had formatted it wrong way: I wrote /dev/sdb instead /dev/sdb1, and now I have no ability to use this drive.

fdisk /dev/sdb
fdisk: unable to read /dev/sdb: Input/output error

Last saturday I have used dd command for writing sdb device with zeros. Today the process has been finished (my second PC run this command for a week). But I found one interesting thing with dd. If I set count = 1 I see next:

bs=512 - Input/Output error
bs=1024 - Input/Output error
bs=4096 - Okay!

But all what I try had no success. sfdisk also says that he has IO error.

The HDD is connected to SATA with no USB adapter.


What I did...

  1. I removed all partitions using gparted
  2. I created a new partition table but gparted creashed
  3. I recreated partitions using fdisk
  4. Something happend in my head and I decided to fill device with zeros using dd
  5. When I started dd and calculated how many days I need to finish the process I pressed Ctrl+C and... After that fdisk says that block 0 is unreadable/unwritable

I have tried sfdisk, wait till dd fill all disk and many other...


dmesg says:

[573000.557900] Buffer I/O error on device sdb, logical block 244187588
[573000.558550] lost page write due to I/O error on sdb

    Input/output error - this isn't caused by formatting /dev/sdb instead of /dev/sdb1. Either your disk is damaged or your USB adapter doesn't work properly. Try to connect the disk directly via SATA, without the USB adapter. – Martin von Wittich Sep 10 '16 at 9:47
  • Yes, I already did it. My bad, forgot to clarify: the HDD is connected to SATA with no USB adapter – Макс Торгунаков Sep 10 '16 at 9:52

    So, can you edit the post to tell how you formatted the drive (which command), if that's what caused the problem? Also, what does dmesg show? (assuming this was on Linux) – ilkkachu Sep 10 '16 at 10:14
  • Then the disk is probably broken. Could you post the output of smartctl -a /dev/sdb? – Martin von Wittich Sep 10 '16 at 10:29
  • Updated post with output of "smartctl -a /dev/sdb" – Макс Торгунаков Sep 10 '16 at 10:40

If 4k sectors are possible to write and the HDD runs fine, it might mean that this is a native 4k HDD (sometimes called advanced format) without the possibility to emulate 512 byte sectors. I haven't seen such drives, yet. Every drive I used could emulate 512 sectors, it just ran a bit slower, because of unaligned access.

You need to check with dd if=/dev/sdb of=/dev/null bs=1m if the HDD would start to read and not abort instantly (1m is multiple of 4k). If the dd command runs fine then it seems it is a 4k drive. If you want to access such HDD, you need tools that are capable to align accesses to 4k sectors.

  • plex@ubuntu-server:/dev$ sudo dd if=/dev/zero of=/dev/sdb count=1 bs=1M 1+0 records in 1+0 records out 1048576 bytes (1.0 MB) copied, 0.0117557 s, 89.2 MB/s – Макс Торгунаков Sep 10 '16 at 10:50
  • It might also be the USB chipset in the enclosure. I formatted drives in my PC implicitly using 512 sectors, then put it in my enclosure and my partitions were unreadable. I discovered the enclosure only supported 4k sectors and the partitions weren't properly aligned for it. – Hoov Sep 10 '16 at 10:51
  • No difference in behavior between connecting via USB and SATA – Макс Торгунаков Sep 10 '16 at 10:55

From the looks of it, I'd guess the disk's dead, dying (or was faulty from the beginning maybe). Formatting the device instead of partition shouldn't be able to do this, happened to me a few times as well, without any damage to device (unlike the data... :)

I have a similar disk, 2TB external USB3 Seagate, I'll post my smartctl output for comparison. For the moment, I'd try running the extended self-test (using either the gui GSmartControl or smartctl. It takes time, for my drive about 6 hrs, yours should be roughly half that tme.)

IMHOAFAIK, it's a hw error and the disk's done for, I'm afraid , but I'd do the extended offline self-test nevertheless. Is it still under warranty, by chance?

  • No the disk is in perfect condition. The high Load_Cycle_Count is something he should take care of, yes. This is a bug in the HDD firmware (powersaving is too Windows-specific). There might be a workaround for Linux, I don't know. Otherwise there are no problems. – Martin Sugioarto Sep 10 '16 at 16:04
  • No, warranty has expired. That is a reason why I try to fix it... – Макс Торгунаков Sep 10 '16 at 18:42
  • @MartinSugioarto - the drive APM and AAM can be adjusted in Linux as well, at least with most HDD. Snce I don't know how to do it in terminal, I use the Gnome Disks app for the task - menu - Drive Settings <C-e> and from there you can disable/adjust APM,AAM,standby and writecache. – Jan Stavěl Sep 10 '16 at 21:36
  • As for the hw/fw failure - I had a HDD once, that was in perfect health according to SMART and other test, seemed to be writing data, but wasn't able to read a single bit from them - The sounds he started to make (and which intensified gradually) however betrayed him..The heads crashed on the platters in a matter of days. Doesn't need to be the case here, just sayin'... – Jan Stavěl Sep 10 '16 at 21:50
