Fastest Cf Card Used
« on: December 11, 2004, 12:05:09 am »
What's the fastest CF card at 2 or 4Gb that anyone has used successfully in their 6K? Brand, size and speed would be nice. CF is coming down so quickly now. I've seen a lexar 80x 2Gb card for less than $200 at Costco.com. Hard to pass up but I don't want to buy something the kernel can't deal with correctly and consistently.

Thanks in advance!

Went out on a limb and picked up an Hitachi 4Gb microdrive. Had to repartition it several times to get it right but finally have it working as a Win95 FAT32 drive, thanks in  large part to one of the posts I found on this site. There were some differences so basically this is what I did

umount /dev/hda1
fdisk /dev/hda1
p (to view partition table)
I then deleted all four partitions that were on it, and wrote (w) that information to the drive, and rebooted
umount /dev/hda1
fdisk /dev/hda1
c (to create new partition)
I started the partition at cylinder 1, instead of 2 as the other instructions directed. Used default choice of 991 for the ending cylinder.
t (to set the type)
b (to select Win95 FAT32)
w
and rebooted
mkfs.vfat -v -F 32 /dev/hda1
and rebooted

Now my Z, and Windows can write to and read from  the drive. Two small quirks though. I cannot seem to create an all-uppercase directory name on the drive (though mixed and lowercase are fine). When I try it merely writes it in all lowercase. And Zaurus File Manager will not write to the drive. It will create directories but will not actually write data. No problem though because it's just as easy to pull the drive out of the Z and insert it into a card reader, and that also allows me to drag and drop normally (one of the drawbacks of the 6K is that it does not act like a plug and play USB slave should).  I think the case thing may be due to the fact that the early FAT32 standard may not have supported case-sensitivity 100%, though that's just a guess. I would have liked to use fdisk on XP to do the partitioning, or even BootIT, but I couldn't find fdisk on my laptop, and my BootIT CD was at home, while I did this at work today.

One other thing is that I had to stick a small length of labeling tape on the back and front of the microdrive and join the ends together in order to create a "pull" that enables me to get the drive out of the Z. Before I thought to do this I had to very carefully pull it out of the Z using a fingernail. Now I can even tuck the pull into the gap between the drive and the Z so it isn't hanging out there. I was careful not to extend the ends of the tape more than a quarter of an inch or so onto the sides of the drive. The instructions  say not to put on any other labels, or even write on the drive. I think this may have to do with heat dissipation, and so I wanted to use as little tape as possible to create the pull.

The drive seems as quick as the solid state 4x Lexar CF card I was using with no noticeable latency on spinup. With 4Gbs of space (2.9Gb left), I shouldn't need to consider any further storage for the foreseeable future.

gdog,

Have you noticed any problems using the Hitachi drive to install programs on?  Or what about using the drive to save your voice recorder data to?

Mine is formated FAT16 and won't let me do those things.  I don't care about windows seeing the drive since I never touch the stuff.  But I wonder if it's a formatting issue I'm having.  Could be since ext2 won't show up with my mail client, so I suspect Zaurus wants something I'm not showing it.
SL5500 (Broken Screen, but still works)
SL6000L (Needs Sled, will pay $250)
64MB SanDisk CF (FAT16)
5GB Seagate Microdive (ext3 Flakey, sent back)
4GB Hitachi Microdrive (Fat16) replaced flakey 5GB Seagate
1GB Pq1 SD Card (Fat16)

Sgtron,
I haven't installed anything to it yet. In fact I've only installed one program to a card and that was to my SD card. I partitioned the Microdrive ext3 at one point but because Windows wouldn't recognize it I redid it to FAT32.

Good Luck,
