[mythtv-users] OT-RAID 5 failure. MDADM experts? Seagate 1.5TB failure

[Mark]

Hello,
I have been bitten by a firmware issue on the new Seagate 1.5TB drives.  
Before the firmware update on the drive, they go offline. I have now 
updated the firmeware on the drives, but two went off-line in a 4 drive 
RAID 5. 

Two are degraded now and I am unable to start the array.
Details.  /dev/sdb,c,d,e built previously with mdadm and was working fine.
Now, I am unable to assemble ( even with force ) my /dev/md0 as two are 
failed.

Here is the mdadm examine on the 4 drives:

 mdadm -E /dev/sd[b-e]1
mdadm: No md superblock detected on /dev/sdb1.
/dev/sdc1:

If I try to assemble with the 3 (  mdadm -A /dev/md0 /dev/sd[c-e]1 ) I 
get the results below:

mdadm: cannot open device /dev/sde1: Device or resource busy
mdadm: /dev/sde1 has no superblock - assembly aborted


Ideas on what to try?
