Ranish Partition Manager revived (Announce)

posted by fritz.mueller Homepage, Munich, Germany, 17.01.2023, 22:44

Hi,
I just wanted to report two more things with the actual version of ranish:

a) when I have a HD with 3x primary partitions and an extended partition with several logical volumes inside: I deleted one of the logical volumes, no problem, but: I found no way to come out of this window again, I always get a message that I have to fix problems at the main window (primary partitions) first. How do I come back there?
Message: You cannot save object if one of its parents is invalid or is not saved.

b) I have an old DELL laptop, in about built 2009, last bios 2010, that has no options to change BIOS settings from UEFI, AHCI etc. back to old system. Nevertheless it is able to handle SATA SSDs in FreeDOS, means, I can boot from external USB diskette, run ranish and create partitions, write a system on the SATA etc.
The interesting thing is:
I tested with a 256 GB SATA SSD, created partitions etc, formatted, checked surface of SSD, nothing special happened.
When doing this test with a 1 TB SSD from WD, creating partitions etc. works, but when I come to formatting or checking surface, there is a stop at 13 percent I get a message "One or more bad sectors found on disk" - OK - clicking on OK gives a message "BIOS error code BB".
Format says: Cluster Stats: 30516378 used. 0 bad, 943 items, 30516379 last.
Safe format: have to trash 242.193 used data sectors!
Mirror map is 1908136 bytes long, 238506 sectors mirrored.
Warning: Each FAT is 238410 sectors, > 16 MB-64K, Win9x incompatible.
100 % completed.
Optimized initia Root Directory size : 1 clusters.
Safe Quick format complete.
976.762.552,5 kb total disk space
976.524.064 kb available on disk
32 kb in each allocation unit.
30.516.377 allocation units on
disk.
After this I tested another 1 TB SSD from Samsung, disk1, 953869 mb, partition 1 NO GPT guard partition and ran verify disk surface (v).
At 13 % verifying I get the following message:
One or more bad sectors found on disk. OK
This time: BIOS error code 04.

Forgot to mention: There is no error message at virtualbox 2TB HD.

I am not sure if the two HDs really have a bad sector there.
The two HDs work fine on the same machine with Linux.

There is another thing that I noticed with a 2 TB HD. dosfsck reports an error message with 77 FATs, I could not test it once again at the moment, but I assume it is reproducable. But I think this is a dosfsck bug.
