Hello,
I finally got around to installing the Kronos 1.5 update. The installer reported success and the Kronos rebooted, reporting without incident.
But, now I'm observing that that the Kronos appears to be having problems with an external USB hard drive where none existed before. The problem is that the drive intermittently becomes invisible to the Kronos, as if it had been physically unplugged. It doesn't show up on the Disk page's drive selection list, etc. But it will usually reappear if the Kronos is rebooted.
Just curious, has anyone else seen this kind of misbehavior since installing 1.5? If so, were you able to fix it or work around it somehow?
thx -- John D
Note that this drive has been in continuous use for about 2 months, with no such problems appearing previously. It is a LaCie D2, 2 terabyte drive. The coincidence is a little suspicious.
Right now I'm trying a Quick FAT32 reformat to see if that improves the situation. Fortunately I didn't have any important data on this drive! (I must say, this "quick" reformat is taking quite awhile... how long would a "full" reformat of a 2 TB drive take?)
(BAD) USB external drive problem immed. after 1.5 update??

I think a full format takes hours to days.

In theory FAT32 supports drives up to 2TB.
Hard to say exactly why Partition Magic would refuse to format past 200GB but it could be a BIOS issue as many older BIOSes did have limitations like that. If it's a recent BIOS I'd have thought that's less likely.
Also, I can't remember for sure without looking it up but there will be a limit to how many disk sectors FAT32 can cope with, which is probably held in a 32-bit number so it would be 2TB with 512 byte sectors. If the sectors on your disk are smaller than 512 bytes then the size it could cope with would reduce below 2TB, but I'd be surprised if they're small enough to limit it to 200GB. On many drives you can change the sector size through the BIOS, but only after backing up the contents of the disk first! Might be worth having a look though if you can, just to see what the sector size is without changing it, as that might show whether or not it could be the problem.
No doubt there are other possible causes too.
And yes, a full format of a 2TB drive could take quite a while! Depends on the drive and the controller, but it could run into hours. Think yourself lucky you're not doing multiple low level format and test cycles - I can remember those running for 2 or 3 days way back when the drives were only 300MB!

Thanks for the info. I'll try again on a different computer. What I did was take a NTFS formatted drive, created a 50GB partition and formattted it FAT32. Took about an hour, mostly verifying the surface. The actual format was very quick. Then I expanded the partition in 50GB stages until it got to 200GB and then it wouldn't go any further. Maybe I should have formatted the thing in one go. Just didn't want to wait that long.
