This is partially a Linux question, with some Windows overtones.
Apologies if it bothers people, but it shows Linux in a good light so I
don't think it's totally out of place.
A friend just got a couple of Seagate Barracuda ST15150N 4GB SCSI-2
(50-pin) drives, and gave me one. (A *good* friend. :->) I installed
it in my machine, and brought it up in Linux, ran fdisk, and created a
couple of test partitions, a 500MB Fat32 partition and a 800MB ext2
partition.
When I rebooted into Win98, it saw the drive as about 7GB. Well,
actually, it saw a 128MB partition, and a 7.something GB partition.
Hmmmmmmmmmmm. Since I didn't have any data on it, I partitioned it with
Windows FDISK, and rebooted into Linux.
Wow, Linux shows the same partition table I started with. No changes.
Huh. So, curious, I re-fdisk and create an ext2 partition. Okay, that
works. I mount it, copy some data, read it back, etc. Then I format the
other partition as msdos, and I can't mount it.
Boot into Windows, the partitions have swapped places - the 7GB comes
first, then the 128MB. Still no dice.
My friend comes over - he can't get anything done in his machine, either.
The same drive also shows up as 7GB. (He only runs Win98 and NT. I can
forgive him if he keeps giving me 4GB drives. ;-> ) We temporarily install
Partition Magic 4.0 on my system - it can't even see the disk.
I have an NCR53c825 SCSI card, he has some kind of Adaptec card. Again,
Linux doesn't seem to have a problem using this with ext2 filesystems.
Win98 sees *something* awfully wierd.
I don't have the drive here, but ISTR it had a sticker on it, "formatted
to 256 something". Could it be that the sector size is 256K and not 512K,
and Linux can handle this and Windows/FAT can't? Any other suggestions?
Sincerely,
