Capacity of large IDE disk is not recognized correctly
Support knowledgebase (jsj_large_disk_32gb)
Applies to
SuSE Linux: All versions
Symptom:
Your IDE hard disk ist larger than 32 GB. Linux does recognize
the first 32GB of space only.
Cause:
There may be several causes for this effect:
- up to kernel 2.2.10:
The kernels up to 2.2.10 limit the number of maximal cylinders of a
disk internally. The limit is 65535 cylinders, leading to
a maximum capacity of 32GB.
- from kernel 2.2.11 on:
- The BIOS of your computer limits the number of cylinders.
- The hard disk you are using has a jumper, which limits the
geometry.
Solution:
- up to kernel 2.2.10:
Use a newer kernel version ;-)
- from kernel 2.2.11 on:
- Try to upgrade the BIOS of your computer. If this fails, you may
not use the full capacity of your disk.
- Change the positions of the jumper limiting the geometry of the
disk according to the manual of your hard disk.
Example Maxtor 96174U8: remove jumper J46.
