My Mac OS Lion 10.7 FileVaulted HD does not boot, prohibitory sign, stop sign appears some minutes after boot starts. Disk Utility repair shows four error messages:
Unable to bootstrap transaction group 2517: inconsistent crosscheck
No valid commit checkpoint found
The volume xxxxxxxxxxxxxx(here it shows physical volume number) was found corrupt and can not be repaired.
Problems were encountered during repair of the partition map
Error: Storage system verify or repair failed.
(the same with 2518, 2519 and 2520 transaction group)
I suppose it is serious bug in Mac OS Lion managing FileVault and wonder what the help could be?

Most likely culprit is your Lacie drives which are notorious for flaky power supplies which cause just the sort of erratic behaviour that you describe. Have had similar issues myself. Lacie has been good about replacing my power converter-- twice. If you have seven of them, good luck finding the bad one or more. Like I said, the behaviour is erratic. Sometimes it'll work sometimes not. I can't comment on Samsung drives because I've never used them and have never heard anything about them. Same with Softraid. Why not just use Disk Utility. Sounds like you're ready for an external hardware raid. This will be much faster, much more reliable, and may even be cheaper than seven firewire drives. Check out G Tech, and Maxx Digital for starters.
Best of luck

Unable to bootstrap transaction group: inconsistent crosscheck

Disk Utility reports the following errors when I run it on my startup disk 'Macintoch HD'. When I click 'repair' it is not able to complete the repair and suggests to reboot from the recovery disk. When I do that and run DU on 'Macintosh HD', it reports no errors and shows a green result message. I can repeat the reboots and checks with the same results.
What does this mean and how do I resolve it, shy from reinstalling everything?

I had exactly the same problem with Disk Utility reporting "Unable to bootstrap transaction group xxxx: inconsistent crosscheck" errors when booted from Macintosh HD but no errors when booted from the Recovery HD. The following resolved it for me:
1. Turn off FileVault; decrypting the drive took about an hour
2. Run Disk Utility - reported two Macintosh HD, one greyed out
3. Reboot (to see if it resolved 2)
4. Run Disk Utility from Macintosh HD again; only one Macintosh HD and no errors reported
5. Turn on FileVault; encryption took another hour or so
6. Reboot again
7. Run Disk Utility from Macintosh HD again; no errors reported
No reformatting, reinstalling or replacing hard drives, as other reports have suggested.

DiskUtility error: unable to bootstrap transaction group

I get this bootstrap error with a checksum mismatch but searching only found 1 other person with 'chksum mismatch' with 1 reply which was not of use.
"Unable to bootstrap transaction group 611: cksum mismatch
Unable to bootstrap transaction group 609: cksum mismatch"
MacBook Pro 13" early 2011, 10.7.2, Kingston 60 GB SSD as boot volume. FileVault full disk encryption is enabled.
I get this error when use Verify Disk when booted from the volume or even when I try to Repair Disk when I boot from a Lion flash drive or in target mode.
I also get the green OK messages at the end but when I Verify/Repair again, it still shows the same bootstrap errors. Why does this happen? Why doesn't DiskUtility fix it? Is it a bad error? Seems odd that it says OK at the end but still shows the errors.
Thanks.

I'm seeing this issue too. Disk repair wont fix it:

That was sensible.

Those symptoms are consistent with a failing or failed hard drive.

Since upgrading to FF 4, I have constant crashes (updating graphics drivers did not help). now all my bookmarks are gone. When I try to restore them, I get error message: "Unable to process the backup file".

Since I "upgraded" to FF 4, I have constant crashes (I tried updating my graphics drivers--it did not help) and now all of my bookmarks have disappeared. When I try to restore them, I get this error message "Unable to process the backup file". I have lost years of bookmarks...please help.
I am using Windows XP, SP 3 if that matters.

I am also unable to restore any of the backups of the bookmarks, both automatic backups and two backups that I created manually. Since I was able to restore backups before, and since no changes have occurred to these backup files, the problem must be with Firefox.
Right before my bookmarks disappeared, FF crashed and I accidentally started FF 3.5. When I saw what I did, I ended the Firefox process and started FF 4. That's when all my bookmarks were gone and I discovered I couldn't retrieve any backups. I did note that an add-on was updated when I restarted FF. Maybe that's the problem. Does FF have a Safe mode?

It is not clear how or where you "added" your email, but you cannot create an Apple ID using an email address that is already associated with another Apple ID.
If that is what you did, delete that email address from your family's Apple ID. You should be free to create a new one.
Do all that by starting here: https://appleid.apple.com/
Select "Manage your Apple ID". Log in with your family's Apple ID and then delete your own email address wherever it appears.
Save Changes, log out, and create the new one using the same website. This time select "Create an Apple ID".
Please don't forget your security questions, and be sure to specify a "rescue email address" that is separate from all other Apple IDs. You will avoid so many problems that way...

Why BDC when we can do the same with Bapi's

Hiii
Plz tell me why BDC when we can do the same with Bapi...
plz list out the differences clearly
Thanks & Regards
krishna

If the same functionality can be achieved by BAPI then we generally go for BAPI instead of BDC. The main reason is that the screen no can change in the next version and in that case the BDC code will not work. But if no BAPI is available then we go for BDC.
Sometimes we need to handle a large amount of data in BDC/BAPI in which it is not preferable to use 'CALL TRANSACTION' command. If the corresponding BAPI internally use 'CALL TRANSACTION' command. Then instead of that BAPI we create a BDC with SESSION METHOD.
Ex: IDOC_INPUT_ORDERS internally use CALL TRANSACTION. So if we need to use a large amount of data we create a BDC with session method instead of using IDOC_INPUT_ORDERS.
