I already wrote what happened to my Maxtor hard drive, it has bad sectors. At first I thought that I only have bad sectors in first out of two partitions, but it turned out that I was wrong and that my other partition (which has only 3GB free space out of 40GB size) also has bad sectors. I found out about it when I saw that Windows reported my partition as RAW instead of NTFS.
NTFS to RAW file system change happened by itself, I think from bad sectors because I didn’t delete partition or change anything on that partition. We all know that when you have problems with your hard drive you should NOT write anything to it and also if you have bad sectors they can spread. Because of that, I disconnected the drive until I could find another drive with enough space to backup my data.
When I freed up some space on my 200GB HD, I connected hard drive with bad sectors to my computer again.
This is what I did to solve my RAW file system problem:
- go to Control Panel>Administrative Tools>Computer Management>Storage>Disk Management
- right click on problematic partition and chose option Change Drive Letter and Paths
- click Add (if your partition is not already mounted) and select drive letter you want, I used letter Z so I could easily distinguish it from other partitions
NOTE: If you try to open that Z: partition from My Computer, Windows will report that it’s not formatted and ask if you would like it that he formats it… since you really, really dont want that to happen (under any circumstances) you allways select NO to this question :)
- go to Start>Run (or just press Ctrl+R)
- type cmd to open command prompt
- then in command prompt type “chkdsk Z: /f “ (Z: is drive letter under which you mounted your partition, /f option is to make chkdsk fix errors, maybe I needed to use /r but it would probably take very long time – locates bad sectors and recovers readable information)
Chkdsk utility reported and fixed some errors. And finally now my Z: partition was once again in NTFS file system and readable (me very happy :)). If you have bad sectors like I did, you should backup your data ASAP.
I started to copy files from that partition to my 200GB and managed to save almost all of my data. There were only ten or so small pictures which I was unable to recover because of bad sectors. So the total size of lost files is approximately about 5MB which was nothing compared to about 35GB of data I was able to save.
