Do a "surface check" with partition wizard bootable CD. Of course boot from it. This proves the disk is faulty or not.
You have an external drive with lots of free space? If so backup H, I, K asap.
Would rather advise OP to just copy all data in H,I,K to another drive without using any backup software.Can't understand why he should use a backup software for that.
Let him just copy one folder/file to another external drive and check whether he can read it. If he is not able to then we can think of the permission problem if it arises.
I was performing chkdsk on g: which was showing many read errors so I gave up and shut down the system for last 3 hours. Just now I checked my HDD again and I dont know what happened but my both partitions are accessible now.
I didn't even performed chkdsk on j: even though it is accessible now. BTW I am getting cyclic redundancy error(read error) while copying some files from g: but j: is working fine.
Thanx everyone for helping, I will let you know if this HDD again creates the problem.
Do a surface check! Or use disk manufacturer's diagnostics program. I think disk is dying. CRC errors means hardware errors. Or memory is faulty (quite unlikely if all other disks work without problems).
Make backup/copy all files from faulty drive before you're too late.
That is good news really. I was actually wondering how all of a sudden only G which was your active system drive previously and then J a totally unconnected logical drive can turn RAW. When Partition Wizard showed everything fine and you were also able to explore the partitions and see the folders/files, I was about to suggest that you copy all accessible data in all the partitions to another drive before doing any manipulations on the drive by which time Kaktus entered.
As a matter of fact once you removed the HDD from the lappy and put it inside an enclosure, you should have copied all data in it to another drive, completely wiped the disk and repartitioned them as you like doing away with the hidden partition and previous active system partition.
You should do it now. Whatever data you can copy to another drive (leaving aside those that give CRC errors) copy it. ( I don't think you are going to get into any permission problems. However since Kaktus brought it, do a test copy as suggested in my previous post and complete the copy.)
After that, run the disk manufacturer's repair/diagnostic utility. Check if it repairs any bad sectors and gets you out of the CRC errors. I only hope that most of it will only be your old system files even if it persists..
If your HDD passes the long test and you have nothing else to do, wipe that drive clean ( write all zeros using the manufacturer's utility) and reformat it.However use it only as a backup drive but keep checking the drive's health periodically.
