Hi, I've already posted on the help-forum at ntfs-sourceforge about an NTFS b= ad=20 sector problem. My drive (ntfs-volume) seems to freeze and only then when= it=20 reads a cluster it has written on before in a bad way. I don't know what=20 causes this bad writing : a bad physical sector/track, the last breath of= my=20 harddrive, maybe a too fragmented drive ? ... but my problem started when= w2k=20 created some new inodes/files/cluster allocations? with writing on bad=20 sectors this time needed by booting procedure (past my grub bootloader di= sk). Using the ntfsdriver I was able to mount my primary w2k-ntfs-drive from m= y=20 secondary linux-system-drive. But any look into the root directory or the= =20 seeking for other subdirectories with tab or the direct path to the winnt= or=20 programs subdirectories would cause the same read freezing I've experienc= ed=20 under windows. So I thought my only help was a bypass method avoiding the= se=20 fatal clusters before addressing them and allowing the reading of incompl= ete=20 directory structures. After using ntfsinfo and checking out the last crea= ted=20 files I realized that I hadn't touched my personal documents subdirectory= =20 that day and by trying a direct cd c/DOKUME~1/ I had luck and got past th= e=20 damaged directory structures. Now I've saved all my data on that director= y=20 part (100%) and assume that almost every data on my drive is still there. Thanx a lot to Szaka and Flatcap for helping me (had no knowledge of ntfs= =20 before). Now I would still like to save a few files in some program=20 subdirectories with the help of a badcluster bypass or direct file readin= g=20 procedures. And this problem raised some questions for me : 1) ntfs is transaction based - Is the transaction writing to clusters clo= sed=20 before the clusters are reread ? 2) Could this be a pure over-fragmentation problem ? 3) Is it a typical harddrive problem and is it useful to give the ntfs-dr= iver=20 or libs an emergency-cluster-bypass option ? 4) As I'm new I'd like to ask Szaka about the programs/procedures ntfsmet= a and=20 ntfscat he mentioned on the public board - are they part of the ntfsprogs= =20 under cvs ? (haven't looked into the sources, just part of the docs) Thanks for taking the time Heiko |
