Hi NetWorld A friend of mine has a PS/2 (Dos 3.3) whose hard disk has been partitioned in one 30meg and one 10 meg partitions, For some reason, the 10-meg partition has 4K cluster, while the 30meg one has 2K clusters. Since my friend is using a lot of very small (X00 bytes) files, he needs to get 2K clusters on the 10meg Partition. How on earth can THAT be done ? Thanks for your help Olivier -=- Olivier Barthelemy barthe@hpuxa.ircc.ohio-state.edu MBA Student 1660 N 4th St, #2B, Columbus, Ohio 43201 French TA Tel : (614)-294-3302 evenings Computer consultant Permanent adress : 1 Q Mistral, 13120 Gardanne, France

I fooled DOS with the following: Modify the SYST IND in the Master Boot sector (Partition Table) Replace there 01 (12 bit) with 04 (16 bit FAT) Similar operation for BOOT SECTOR of the partition. There you need to specify the cluster size (DOS 3.1 does not like to go beneath 2k clusters, other allowed 1k as well). Reformat the disk.... and thats it.... Woody

All partitions from 1 - 16 megs have 4 k clusters. Partitions from 16 - 128k have 2k clusters. -- cj in size from 1 - 16 megs are 4
