 +</WRAP>
 +

 +
 +===== Mount/Repair NTFS =====
 +
 +If an NTFS volume mounts as read-only, it is usually due to an unclean shutdown or filesystem inconsistency.
 +
 +Attempt repair:
 +
 +<code bash>
 +sudo ntfsfix /dev/sdX#
 +</code>
 +
 +Create mount point if needed:
 +
 +<code bash>
 +sudo mkdir -p /mnt/ntfs
 +</code>
 +
 +Then remount:
 +
 +<code bash>
 +sudo mount -t ntfs3 /dev/sdX# /mnt/ntfs
 +</code>
 +
 +<WRAP info>
 +**Notes:**
 +
 +  * ''ntfsfix'' performs basic repairs and clears the "dirty" flag
 +  * Full repair should be done from Windows using ''chkdsk''
 +  * If the issue persists, ensure Windows Fast Startup is disabled
 +</WRAP>
 +
 +===== Repair FAT32 filesystem errors =====
 +
 +If a FAT32 filesystem mounts as read-only, it is often due to detected corruption.
 +
 +Check kernel logs:
 +
 +<code bash>
 +dmesg
 +</code>
 +
 +Typical errors:
 +
 +<code bash>
 +FAT-fs (sdb1): error, corrupted directory (invalid entries)
 +FAT-fs (sdb1): Filesystem has been set read-only
 +FAT-fs (sdb1): error, invalid access to FAT
 +</code>
 +
 +Repair the filesystem:
 +
 +<code bash>
 +sudo umount /dev/sdX#
 +sudo fsck.vfat -a -w /dev/sdX#
 +</code>
 +
 +  * ''-a'' automatically repair filesystem
 +  * ''-w'' write changes to disk
 +
 +Note: Ensure the correct device is targeted before running ''fsck''.
 +
 +
 +====== File & Data Operations ======
 +
 +===== Shell toolbox =====
 +
 +==== File operations ====
 +
 +=== Mass renaming ===
 +
 +__**Changing an extension:**__
 +
 +<code bash>
 +for i in *.JPG; do mv "$i" "${i/.JPG/.jpg}"; done
 +</code>
 +
 +__**Changing a prefix:**__
 +
 +<code bash>
 +for i in "prefix"*.png; do
 +  mv -n -- "$i" "${i/#prefix/another prefix}"
 +done
 +</code>
 +
 +  * ''"prefix"*.png'' targets only files beginning with the selected prefix, so unrelated files in the folder are ignored.
 +  * ''${i/#prefix/another prefix}'' replaces only the prefix at the beginning of the filename. If the same text appears later in the filename, it is left untouched.
 +  * In Bash parameter expansion, the ''#'' before ''prefix'' means “match only at the start of the variable value”. Without ''#'', Bash would replace the first matching occurrence anywhere in the filename.
 +  * ''mv -n'' prevents overwriting an existing file if the renamed target already exists.
 +  * ''--'' tells ''mv'' that everything after it is a filename, not an option. This protects against unusual filenames starting with ''-''.
 +  * ''"$i"'' keeps the original filename safely quoted, so spaces and special characters in filenames are preserved.
 +
 +__**Alternative (rename tool):**__
 +
 +<code bash>
 +rename 's/\.JPG$/.jpg/' *.JPG
 +</code>
 +
 +  * Use the ''for ... done'' + ''mv -n --'' loop for safe, explicit prefix renaming.
 +  * Use ''rename'' for concise regex-based changes, especially extension changes such as ''.JPG'' to ''.jpg''.
 +  * On Linux Mint / Ubuntu, ''rename 's/\.JPG$/.jpg/' *.JPG'' usually works because the available ''rename'' is the Perl-style tool.
 +  * On Ubuntu / Mint the Perl-style ''rename'' is a separate package and is not always preinstalled: ''sudo apt install rename''.
 +  * The ''rename'' command is not fully portable across all Linux distributions, because different systems may ship different versions with different syntax.
 +  * For safety, preview first with ''rename -n 's/\.JPG$/.jpg/' *.JPG''.

 +
 +=== Empty a file ===

-===== Data recovery ===== 
- 
-Use **TestDisk** / **PhotoRec** as a first recovery tool. 
- 
-  * **TestDisk** attempts partition repair and file undelete when filesystem metadata is still usable. 
-  * **PhotoRec** performs file carving by signature. It can recover files from damaged filesystems, but filenames and folder structure are usually lost. 
- 
-Do not write recovered files to the source disk. 
- 
-==== PhotoRec: recovered MOV files ==== 
- 
-For some recovered ''.mov'' files, PhotoRec may split the video into separate ''ftyp'' and ''mdat'' parts. 
- 
-In PhotoRec ''FileOpts'', enable: 
- 
-<code> 
-[X] mov/mdat Recover mdat atom as a separate file 
-</code> 
- 
-Sort recovered files by name, then try concatenating matching parts: 
- 
-<code bash> 
-cat f123_ftyp.mov f456_mdat.mov > recovered_1.mov 
-cat f456_mdat.mov f123_ftyp.mov > recovered_2.mov 
-</code> 
- 
-One order may produce a usable file. 
- 
-Sometimes the header/container part may be ''.mp4'' while the media data part is ''.mov'': 
- 
-<code bash> 
-cat f54114560.mp4 f51781632_mdat.mov > recovered.mov 
-</code> 
- 
-Note: This is a recovery attempt, not a guaranteed repair method. For valuable data, stop using the disk immediately and clone/image it before experimenting.
