- I'm using the following format.dat entry, it SEEMS to be working ok:
-
- disk_type = "Fujitsu-M2624S-512" \
- : ctlr = MD21 : fmt_time = 1 \
- : trks_zone = 15 : asect = 4 : atrks = 30 \
- : ncyl = 1429 : acyl = 2 : pcyl = 1435 : nhead = 11 : nsect = 64 \
- : rpm = 4400 : bpt = 39263
-
- partition = "Fujitsu M2624S-512" \
- : disk = "Fujitsu-M2624S-512" : ctlr = MD21 \
- : a = 0, 35200 : b = 50, 35200 : c = 0, 1006016 : g = 100, 935616

- Format Shows:
- Current Disk = sd0: <Fujitsu-M2624S-512 cyl 1429 alt 2 hd 11 sec 64>
-
- Partitions:
- Current partition table (Fujitsu M2624S-512):
- partition a - starting cyl 0, # blocks 35200 (50/0/0)
- partition b - starting cyl 50, # blocks 35200 (50/0/0)
- partition c - starting cyl 0, # blocks 1006016 (1429/0/0)
- partition d - starting cyl 0, # blocks 0 (0/0/0)
- partition e - starting cyl 0, # blocks 0 (0/0/0)
- partition f - starting cyl 0, # blocks 0 (0/0/0)
- partition g - starting cyl 100, # blocks 935616 (1329/0/0)
- partition h - starting cyl 0, # blocks 0 (0/0/0)

- I picked up two for DM1,100 the other day. One vibrates a tiny bit
- more than the other, I don't know it thats significant. The guy
- thru in a photocopy of the manual:
-
- On page 3-3 and 3-6 it says the Zone Partions are:
-
- ZONE I II III IV
- Cylinder 0 to 606 607 to 847 848 to 1157 1158 to 1434
- Bytes/Track 41593 39262 36834 33274
- Actual Sector Length 593.03 593.35 593.52 593.83
- Sectors/Track 70 66 62 56
-
- Table 3.6 Shows the Format Capacity for the Fujitsu M2624SA
- Heads: 9
- Data Block Length: 512
- Number of User Blocks: 1015812
- Number of CE Blocks: 613
- Total # of Spare Sectors: 4900
- Format Capacity: 520.10

- It says that 1429 is the "default" number of cylinders. I'm not
- sure what the other 5 cyliners are being used for. I suppose
- bad blocks, but it could be wasted. I'm only getting about 500
- MegBytes but the book says I should be able to get 520.10. After
- mkfs it comes to 438886 kbytes for the g partition; leaving 100
- cyliners for root and swap.
-
- I suppose that the format program is leaving all of the Zone stuff
- to the SCSI controller. I noticed that format has support for
- zones but I don't know if it's used on SCSI drives.
-
- I tried using 70 sectors but had a problem with label, it
- couln't write the backup labels. But said it wasn't a media
- error. Anyone know how to get out the last 20 magabytes?
