נושא ההודעה: אבדתי FAKE PARTITION TABLE בכונן GPT
|
קוד: |
HI,
I've a, BIOS based, dual-boot desktop, runnung both (fully updated as of yesterday) Arch-64/Windows 10 (originally Win7).
The PC has 3 drives: sda (optical), sdb (2.7 TB GPT based HD, originally containg 8 GPT partitions), and sdc (1.5 TB, MBR based HD).
The sdc contains GRUB and Windows.
The sdb contains 8 Linux and data GPT partitions.
Yesterday, while shutting down Windows, the system hung for a moment than shut down.
Eversince, I can only boot into Windows as Arch won't find linux root..
I would appreciate a detailed help regaining full acsess to all my sb partition (especially a 2.6 TB ntfs partition containg many many photos...).
Thanks up front!
I've booted with SystemRescue CD and got the following: (I'm especially worried about the 64b overlap-see below).
GParted reported thar sdb has no valid fake msdos partition table, but in view of the above overlap, I'm afraid to try to restore.

תודה מייקי

Partition table scan:
MBR: MBR only
BSD: not present
APM: not present
GPT: present
Found valid MBR and GPT. Which do you want to use?
1 - MBR
2 - GPT
3 - Create blank GPT
Your answer: 2
Using GPT and creating fresh protective MBR.
Warning! Main partition table overlaps the first partition by 64 blocks!
You will need to delete this partition or resize it in another utility.
