Dear Sir, I was completely down ! I live again or I resurrect. Those 3 harddisks are now working again! uff uff ufff They got fixed finally successfully, although a first attempt with testdisk.
So the story board is as follows. The PC got frozen, apparently, and somebody, without telling me, cold reset it. The PC didnt like it. The pc has ext3, the system / and those 3 JFS disks (big) running and mounted. So the cold reset resulted in at next power into : mount /dev/X /mountpoint cannot be mounted So I did touch /forcefsck and nothing happened :( I did testdisk and visibly testidks was telling me that hidden sectors or parts problems, continue y/n ? - n so I detected that jfsutils was not installed. So apt-get install jfsutils touch /forcefsck reboot and it worked one hour around,, hard, and I got successfulyl back my 3 harddisks. First conclusions: (1) JFS without jfsutils is not stable compared to EXT3 JFS is more stable than EXT3 in general regarding cold power-ing. JFS is great cuz it checks at single boots the JFS disks & display a msg about it. JFS is highly stable compared to EXT3. Iovin'it (like mac do) besides, "hat'in it": disk crashes (2) JFSUTILS shall be installled by obligation as soon as JFS is there, used in the PC (3) touch /forcefsck is so great and useful, that nothign can replace (4) If case that harddisk with JFS really crashes, ... well you are in shit, really Compared to getdataback for ntfs or fat32, you can recover the disk in almost its integrality. NTFS is so nicely stable I have to say, compared to EXT3. JFS is great and I advice it, since I never got a harddisk crash yet with it. My long experience with EXT is relavtivelty moderated and I got time to time harddisk crashes, with crazy using. so to say: photorec or testdisks are not adapted to linux, or just for basics. I mean who wants a recovery of disk without filenames, when you have 2 Tb? I mean 2 TB of files or 2 TB of mess. Better format /U the disk than recovering, even for important data, I'd say. well , in emergency, why not. So getdataback for ntfs is cool, and visibly it offers more than linux today, in the bad case. (5) JFSUTILS regarding cold power must be installed. (6) Summary: JFS is great and I am glad that it is available to LINUX. Thank you so much. We can open discuss about JFS if you want. I will ssend the output that you inquire. All the best, lot of health, Best regards Y.
