Is there a way to read ext4 partitions from Windows? If so, what can I do?
Best Answer
Ext2Read works well. It can also open & read disk images ( eg: Wubi disk images)
Ext2Read is an explorer like utility
to explore ext2/ext3/ext4 files. It
now supports LVM2 and EXT4 extents. It
can be used to view and copy files and
folders. It can recursively copy
entire folders. It can also be used to
view and copy disk and file
Although claiming a smart resize/move wizard, I have no idea how smart it is on moving ext4 from its beginning, but being one of the best partition managers around it is certainly worth a try.
Please note that when resizing partitions, nobody can guarantee the results. The world's best products are always capable of destroying the disk. I always counsel taking an image of a disk before doing any partition work (using a 3rd-party product - use the problematic Windows Backup only if you have to).
What is 6G mainly used for, for journal, for redundancy, or for indexing?
(Not known yet.)
Why the remaining space 393G not 415G? There is a 22G hole which is rather big.
It's 5% reserved blocks for superuser, which is used to avoid fragmentation. You can adjust it to 1% by mkfs.ext4 -m 1.
What parameters would you advice if this ext4 partition is used to store movie/music files?
You can specify a usage option to mkfs.ext4, e.g., mkfs.ext4 -T large_file, this will let mkfs.ext4 to decide parameters for partitions containing large files.
