i 've been using fedora 14,15 for like few months and i still have a 4GB NTFS partition win XP pro.
i have installed fedora in about like 20gb for root and home ext4.i rarely use win xp nowadays (once in a week) considering i was using windows for like years.i have a common data partition of about 130GB NTFS.

i now dont want to use the windows and i want to convert the 130GB NTFS to ext4, but i am worried that if somehow at some point i crash my partition tables and i was using ext4 i wouldn't be able to recover the data as easily as i would in a windows.

i want to know whether there is a reliable ext4 data recovery tool for fedora?

i googled and i found this link .. if any of you guys have used these tools can you share the experiences ?

Mondo Rescue
TestDisk
safecopy
PhotoRec

I made some very positve experiences with testdisk in recovering lost files and folders, recovering lost partitions and recreating partition tables. It has its unique proceeding and you have to get accustomed to it, but i would recommend it. Here is a nice walk-through, that fellow forum user atipico found the other day http://members.iinet.net.au/~herman546/p21.html#Recovering_a_Lost_Partition_With_
But i would never ever again use photorec, which comes with testdisk! Because with less important data like mine, it is just a time waste, trying to put the pieces together photorec finds.

hi michaaa62 ,
thanks for the link and your comments on testdisk. looks promising.the link has lot of info too. i can handle shell to some extent but still i would prefer an GUI based app.

Or, if it's just for storage, you could just leave the partition ntfs. Linux will mount/read/write an ntfs partition. I have a 250 GB partition I've used for storage for 4 years and haven't had any lost or corrupted data yet.

i kinda feel, NTFS to ext4 transfer speed is slow.and every time i use (copy,cut) NTFS partition the memory usage and CPU usage hits around 30-40% and then usage drops down following that.That's one of the reasons why i want to move to ext4.

A hard disk drive (hdd) can be split into many smaller logical hard disks called partition. A partition is a defined storage area on a hard drives which useful to store data & helpful to running many operating systems on the same hard drive.

In windows operating system partitions information store in partition table but when partition table infect by virus attack or any other corruption reasons, partitions could not be located by the windows system hence, user can not access the partitions and data loss situation occurs.
When a partition is deleted, in general, only its partition table entry is removed from a table; and although the data is no longer accessible, some still remains on the disk until being overwritten. Specialized recovery utilities, (such as TestDisk and gpart), can locate lost file systems and recreate a partition table which includes entries for these recovered file systems. However, some disk utilities may also overwrite a number of beginning sectors of a partition they delete. For example, if Windows Disk Management (Windows 2000- XP, etc.) is used to delete a partition, it will overwrite the first sector (relative sector 0) of the partition before removing it. It may be possible to restore a FAT32 or NTFS partition if a backup boot sector is available.

When you format a disk, the operating system erases all bookkeeping information of the internal address table which helps system to locates, read & display particular files & folders in front of you, but do not panic.

After you accidentally format a disk that has contain your useful data, it can be easily recovered. Reformatting a disk does not erase the data on the disk, only the internal address tables its means your data still on the hard drive. Hence, in the above data lost situations a computer specialist should be able to recover your most vital information from reformatted disk & you can also use formatted data recovery software & formatted data recovery tool to visible & access files/folders again in front of you.

Recover Data for FAT & NTFS is advanced formatted partition recovery software which helps users to recover windows data from crashed hard drives & any other storage media who supported windows os. Formatted data recovery tool is cost effective windows partition data recovery software to recover deleted data or to recover formatted data from fat and ntfs drives visit recoversdata. com
