This bug report seems to be a little confused.

The u flag means not to use the uas driver, which the system wasn't doing anyway. The w flag means to skip testing whether the drive is write-protected, which doesn't seem to be relevant in your case (judging by the log messages). The t flag means to disallow ATA commands, and it used only by the uas driver (not by usb-storage). So it isn't relevant in your case either. > Since then the drive works without any issues: This contradicts what you just said about these quirk flags resulting in sector 0 errors. > dmesg: > 87955.810319] usbcore: deregistering interface driver usb-storage > [87955.817949] Check proc_name[usb-storage]. > [87955.836434] Check proc_name[usb-storage]. > [88077.114724] usb-storage 1-5:1.0: USB Mass Storage device detected > [88077.121004] scsi host7: usb-storage 1-5:1.0 > [88077.125558] usbcore: registered new interface driver usb-storage > [88078.125454] Check proc_name[usb-storage]. > [88078.129499] scsi 7:0:0:0: Direct-Access USB DISK > MODULE PMAP PQ: 0 ANSI: 0 CCS > [88078.139018] Check proc_name[usb-storage]. > [88078.143076] Check proc_name[usb-storage]. > [88078.147121] Check proc_name[usb-storage]. > [88078.151230] Check proc_name[usb-storage]. > [88078.155366] Check proc_name[usb-storage]. > [88078.155800] sd 7:0:0:0: [sdb] 1007616 512-byte logical blocks: (515 > MB/492 MiB) > [88078.159485] sd 7:0:0:0: [sdb] Write Protect is off > [88078.159490] sd 7:0:0:0: [sdb] Mode Sense: 23 00 00 00 > [88078.166791] sd 7:0:0:0: [sdb] No Caching mode page found > [88078.166794] sd 7:0:0:0: [sdb] Assuming drive cache: write through > [88078.183745] sd 7:0:0:0: Attached scsi generic sg1 type 0 > [88078.184349] sdb: sdb1 sdb2 sdb3 sdb4 < sdb5 sdb6 > > [88078.196597] Check proc_name[usb-storage]. > [88078.207147] sd 7:0:0:0: [sdb] Attached SCSI removable disk > [88078.215229] Check proc_name[usb-storage]. > [88176.094207] xhci_hcd 0000:00:14.0: Command completion event does > not match command > [88176.101804] xhci_hcd 0000:00:14.0: Timeout while waiting for setup > device command > [88181.326070] xhci_hcd 0000:00:14.0: Timeout while waiting for setup > device command > [88181.534044] usb 2-1: device not accepting address 9, error -62 > [88183.336151] usb 2-1: new SuperSpeed USB device number 11 using xhci_hcd > [88183.357090] usb-storage 2-1:1.0: USB Mass Storage device detected > [88183.363355] usb-storage 2-1:1.0: Quirks match for vid 0bc2 pid 3332: 800200 > [88183.370500] scsi host8: usb-storage 2-1:1.0 > [88183.666134] [usb.002.011] > /sys/devices/pci0000:00/0000:00:14.0/usb2/2-1 added.
