- Help...
-
- I have a 3000/25 with 2Meg chip 4Meg SC ram. This is one of the very early
- 3000's (40Meg HD [Q P40]). It is running 2.04.
-
- Last week I was using my friends (new) 3000/16 (50Meg [LP52]) and I ran
- 'SYSINFO 3.01' and did a speed test of his drive.
-
- This 3000/16 showed 1.1 MegBytes/sec!
-
- Running this same test on my 3000/25 shows only 770 KBytes/sec ???
-
- Thinking that I must have upgradded something wrong I backed up the system
- and ran prod_prep from the 3000 Install (ver 2.04) disk.
-
- Same results.
-
- I am confused. Is the 52Meg drive really 25% faster than the 40Meg?
-
- Digging a bit further I found a difference in the fastfilesystem between
- the two machines. My 3000/25 has the rev 35 fastfilesystem (size 22412)
- and the 3000/16 had rev 2 of the fastfilesysem (size 20??? [I don't have
- the exact number in front of me]. These numbers were reported from
- hdtoolbox.
-
- If it makes any difference I still have a 1.3 partition on the drive.
-
- Some time ago I read some talk about the mask value for the filesystem.
- It was set to 0xfffffffc by prod_prep. I changed it to 0xfffffffe but
- had no difference.
-
-
- What are the correct setups here... and are these the type of numbers
- I should be seeing? (Commadore?? [Dave H])?
-
-
- Thanks
