On some external USB hard drives, mounting can fail if "lshw" is executed during the process. This occurs because data sent to the device's output endpoint in certain abnormal scenarios does not receive a response, leading to a mount timeout. [ Description of "use_192_bytes_for_3f" in the kernel code: ] /* * Many disks only accept MODE SENSE transfer lengths of * 192 bytes (that's what Windows uses). */ sdev->use_192_bytes_for_3f = 1; The kernel's SCSI driver, when handling devices with this attribute, sends commands with a length of 192 bytes like this: if (sdp->use_192_bytes_for_3f) res = sd_do_mode_sense(sdp, 0, 0x3F, buffer, 192, &data, NULL); However, "lshw" disregards the "use_192_bytes_for_3f" attribute and transmits data with a length of 0xff bytes via ioctl, which can cause some hard drives to hang and become unusable. To resolve this issue, prevent commands with a length of 0xff bytes from being queued via ioctl when it detects the "use_192_bytes_for_3f" attribute on the device. The hard drive device identified with the issue is Lenovo USB 17ef:4531. Tested on HONOR NBLK-WAX9X (C234) Notebook with AMD Ryzen 7 3700U.
