The SATA drivers cannot identify which of the SATA drives you use are 'external'
or 'internal' (unlike external USB drives, the eSATA drives are usually connected
to the same chipset as the system's internal drives). This is a driver issue,
not a Windows issue. A driver could be designed to offer the 'safely remove'
option only to drives that you designate as 'external' drives, but I know of 'no
such animal'... SO, since the driver cannot tell which drives are 'external', it
has to offer the 'safely remove' option for all SATA drives.
Like I said, many of the older "SATA-150" motherboard/controller card chipset drivers
offer no 'safely remove' option; again, this is a driver issue. The operating system
used doesn't matter. My AMD 3000 has 98SE, XP Pro and Ubuntu (Linux), and to really
'safely remove' an eSATA drive in any O.S., the whole P.C. has to be shut down!
"eSATA" drives typically connect to eSATA 'brackets' fitted into PCI slots in the
back of the case, said brackets connect directly to the motherboard's SATA chipset
(or the SATA controller card).
Since the eSATA drives connect to the motherboard/controller card in the same manner
as internal SATA drives, you have the same 'sustained' data transfer rate as the
internal SATA drives. YES, you could set up an eSATA drive to be a system
boot drive!
Someone will read the above and say "Aren't eSATA enclosure chipsets 'SATA-150' speed,
vs. 'SATA-300' speed for a direct-connected internal drive on a newer motherboard
chipset?" That's true, but the '150 MB/sec' and '300 MB/sec' speeds are BURST speeds,
not SUSTAINED data transfer speeds. An eSATA-150 drive would still be 'faster' than
an equivalent IDE (ATA-133/100) hard drive.
I love my eSATA drives! Two W.D. 500 GB SATA's in Vantec eSATA/USB 3.5" enclosures;
they run at a consistent 3 GB+ Per Minute sustained data transfer speed :^D

Athlon 3000+ 939 - 1GB RAM = 98SE (@768 MB RAM) & XP Pro SP2
Athlon 4000+X2 AM2 - 3GB RAM = 2000 SP4 & XP Pro SP2
IBM ThinkPad PIII 933 - 512 MB RAM = 98SE & XP Pro SP2
