Unmounting removable IDE hard drive


Hi

Is it safe to unmount a removable IDE hard drive and then removing it physically while the computer is running?

thanks

sorry, i was kind of in a hurry when i asked my question at first

i just checked on the box to get more specification

the model is SNT-169A133

I'll give out some more details written on the box that may be more usefull for you to answer me:
-Real RAID/SERVER Level mobile rack
-IDE, ATA100/ATA133. U3W. SCA. FIBER CHANNEL
-Auto Handle Actuated & Auto Plug-in
-Power control keylock, hot swappable

Does hot swappable means it is safe?

I can't post links since i'm under 5 posts so you can google the model number if you want more specification.
Or you can just ask me.

i put the model in google and the sunnytek website mentions "hot swap" in the specifications
( http://www.snt.com.tw/product.php?mo...w&cid=5&pid=16 )
but ide doesn't support hotswap.
I have seen some mobile trays that were hotswap but they were connected to a special "ide" controller.

Generally you could unregister the drive from the bus (man hdparm) and then you could power it off, but
as the hdparm manpage says
Code:
-U     Un-register an IDE interface.  Dangerous.  The companion for the
              -R option.  Intended for use with hardware made specifically for
              hot-swapping  (very rare!).  Use with knowledge and extreme cau-
              tion as this can easily hang or damage your system.  The  hdparm
              source  distribution  includes  a  'contrib' directory with some
              user-donated scripts for  hot-swapping  on  the  UltraBay  of  a
              ThinkPad 600E.  Use at your own risk.
I don't have much experience with hotswap ide hardware (i don't think that many exist) but i wouldn't do it if i were you.
