Hi!
First of all sorry if this is the wrong place to ask, if it is, please point me to a better suited channel!
Anyway I’ve got this old 2TB HDD attached to a rpi 4b, it worked flawlessly until now, the last few days it started disconnecting randomly…
If i reboot it mounts back again.
This is the df
output:
/dev/sdb1 1.8T 535G 1.2T 31% /mnt/2tb
And this is sudo dmesg | grep sdb
(the device is sdb ofc).
[ 14.970908] sd 1:0:0:0: [sdb] 3907029168 512-byte logical blocks: (2.00 TB/1.82 TiB)
[ 14.978857] sd 1:0:0:0: [sdb] 4096-byte physical blocks

[ 15.051196] sd 1:0:0:0: [sdb] Optimal transfer size 33553920 bytes not a multiple of preferred minimum block size (4096 bytes)
[ 15.065585] sdb: sdb1
[ 15.068403] sd 1:0:0:0: [sdb] Attached SCSI disk
[ 22.631983] EXT4-fs (sdb1): recovery complete
[ 22.660922] EXT4-fs (sdb1): mounted filesystem with ordered data mode. Quota mode: none.
The device has an external power supply of its own, so it’s not a power issue… This setup worked for a couple of years.
I cannot see anything wrong here, pheraps is the HDD which is going bad?
Please post a full dmesg and a full list of specs
