Remove exfat-fuse dependency. Log: Remove exfat-fuse dependency
Remove support for FAT32 format. Log: Fix fail to format disk to FAT32 Bug: https://pms.uniontech.com/bug-view-299499.html
cannot obtain model info from either smartctl nor lshw commands, try with udevadm command to obtain ID_MODEL field. Log: fix block model missing. Bug: https://pms.uniontech.com/bug-view-322579.html
Changes: 1. Reserved space handling - Now counts reserved blocks as used space for ext2/3/4 filesystems - Matches behavior of standard tools like df 2. Mounted device detection - Uses stat-based calculation for accurate free space on mounted devices - Falls back to previous method for unmounted devices Technical Impact: - Fixes discrepancy between displayed and actual available space - Provides more consistent behavior with system utilities Log: Improved ext* filesystem space calculation accuracy Bug: https://pms.uniontech.com/bug-view-323359.html
-- In the special platform, the stroage interface show error.
Reviewer's GuideRefactors ext* filesystem usage calculation to rely purely on dumpe2fs output and statvfs, adjusts device model/interface detection, introduces Qt5/Qt6‑aware build and translation setup plus an optional DBus auth bypass, and makes small logging/formatting and include tweaks.

There was a problem hiding this comment.
Hey there - I've reviewed your changes - here's some feedback:
- In getDiskInfoInterface(), the sysfs path is hard-coded to
/sys/block/sdd/device/spec_version; consider deriving the block device name fromdevicePathso the UFS interface detection works for arbitrary devices instead of onlysdd. - The new udevadm model fallback in getDiskInfoModel() builds a shell command with an unquoted
devicePathand greps the output; usingudevadm info --query=property --name=<device>and parsing key/value lines directly (with proper quoting) would be more robust and safer. - Replacing
Qt::endlwith"\n"in logging changes flushing behavior; if immediate flush after each log line is still desired, consider callingts.flush()explicitly.

Please address the comments from this code review:
## Overall Comments
- In getDiskInfoInterface(), the sysfs path is hard-coded to `/sys/block/sdd/device/spec_version`; consider deriving the block device name from `devicePath` so the UFS interface detection works for arbitrary devices instead of only `sdd`.
- The new udevadm model fallback in getDiskInfoModel() builds a shell command with an unquoted `devicePath` and greps the output; using `udevadm info --query=property --name=<device>` and parsing key/value lines directly (with proper quoting) would be more robust and safer.
- Replacing `Qt::endl` with `"\n"` in logging changes flushing behavior; if immediate flush after each log line is still desired, consider calling `ts.flush()` explicitly.

**issue (bug_risk):** Subtracting `reservedBlocks` from `freeBlocks` likely underestimates user-available space for ext*.
On ext2/3/4, `dumpe2fs` typically reports `Free blocks:` with reserved space already excluded, and also exposes `Reserved block count:` separately. Assuming `freeBlocks` includes reserved blocks and subtracting `reservedBlocks` again can double‑count the reservation and under‑report available space. Please confirm the semantics against real `dumpe2fs -h` output and adjust the computation accordingly (e.g., use `freeBlocks` as‑is and keep `reservedBlocks` only as metadata, or derive used space from `blockCount - freeBlocks` while tracking reserved separately).

**suggestion (bug_risk):** Using `f_bsize` for filesystem size may be less correct than `f_frsize`.
`statvfs` typically defines total size as `f_blocks * f_frsize`, while `f_bsize` is only the optimal transfer block size and may differ. The previous use of `f_frsize` for total size followed that convention. I’d keep `fileSystemSize = f_blocks * f_frsize` and only switch free space to `f_bavail * f_bsize` to avoid incorrect total size on filesystems where these fields differ.
```suggestion
if (ret == 0) {
fileSystemSize = static_cast<Byte_Value>(sfs.f_blocks) * sfs.f_frsize;
fileSystemFree = static_cast<Byte_Value>(sfs.f_bavail) * sfs.f_bsize;
} else {
