Yes, this depends upon your distribution and its startup system. In
Slackware, the startup script /etc/rc.d/rc.S is run before going to
multiuser. It has the following lines:
-8<------------------------------
# Check the root filesystem:
if [ ! $READWRITE = yes ]; then
RETVAL=0
if [ ! -r /etc/fastboot ]; then
echo "Checking root filesystem:"
/sbin/fsck $FORCEFSCK -C -a /
RETVAL=$?
fi
# An error code of 2 or higher will require a reboot.
if [ $RETVAL -ge 2 ]; then
# An error code equal to or greater than 4 means that some errors
# could not be corrected. This requires manual attention, so we
# offer a chance to try to fix the problem in single-user mode:
if [ $RETVAL -ge 4 ]; then
echo
echo "***********************************************************"
echo "*** An error occurred during the root filesystem check. ***"
echo "*** You will now be given a chance to log into the ***"
echo "*** system in single-user mode to fix the problem. ***"
echo "*** ***"
echo "*** If you are using the ext2 filesystem, running ***"
echo "*** 'e2fsck -v -y <partition>' might help. ***"
echo "***********************************************************"
echo
echo "Once you exit the single-user shell, the system will reboot."
echo
PS1="(Repair filesystem) \#"; export PS1
sulogin
-8<------------------------------
So if fsck is able to automagically repair your / file system during boot
everything is fine. If fsck fails you will be given a root prompt where
you can make your own attempt to fix the broken / file system.
regards Henrik

I have never seen a corrupted partition table (or list, in this case) because of power failure or software disaster (only because of operator error or hardware failure in that precise area). Only the filesystem is normally affected. On the other hand, there are good tools to find out the partition layout if it is deleted. Plus, you can have the data to recover the partition layout backed out, even printed in paper. On the other hand, I have known of badly broken LVMs, and /I/ don't know how to recover those. There are people that do know, but as I'm not one of them, I keep out of using LVM for that precise reason ;-) -- Cheers, Carlos.

On the rest, I could recover all without needing the backup. -- Cheers, Carlos.

So none of you can come up with and answer? Come on people. Maximum number of partitions on a hard drive. easy question. Found the answer here: http://superuser.com/questions/368173/what-is-the-maximum-number-of-partitions-that-can-be-made-on-a-hard-drive "The EFI specification mandates that a GUID Partition Table (GPT), which all modern operating systems support, is capable of containing a maximum of 128 partitions on any size hard disk. GPT is also required to boot from hard disk drives larger than 2 TB."

GPT is also required to boot from hard disk drives larger than 2 TB." That's not a limit. The GPT can be any size from 4 partitions and up. To be compatible with EFI, it needs to accommodate _at_least_ 128 partitions. -- Bob Nichols AT comcast.net I am "RNichols42"

https://en.wikipedia.org/wiki/GUID_Partition_Table#Partition_table_header_.28LBA_1.29
«The partition table header defines the usable blocks on the disk. It
also defines the number and size of the partition entries that make up
the partition table. The EFI stipulates a minimum of 16,384 bytes be
reserved for the partition table array, so there are 128 partition
entries reserved, each 128 bytes long.»
Notice the wording "minimum". There can be implementations using bigger
sizes, thus.

No, not that easy. Traditional or new (GPT)? Version of driver? Because
traditional partitions with the old scsi drivers was limited to 15
partitions (numbered 1 to 15). And Haines Brown is using traditional
partitions (he has one primary, then logicals from number five upwards,
thus there must be one extended. Still, his setup is within that limit.
With the current driver, however, there is no limit on the number of
traditional partitions.
