When I plug-in an USB stick (FAT) into my Centos Linux machine, all files have the executable bits set. After having copied the directory structure to my hard disk I remove the executable bits recursively just from the files and keep those on the directories with following command:
chmod -R -x+X *
Explanation:
-R – operate recursively-x – remove executable flags for all users+X – set executable flags for all users if it is a directoryChange ./ to the root directory you wish to search in. Change -7 to +7 for files changed more than a week ago.
find ./ -mtime -7 -print-mtime n[smhdw]
If no units are specified, this primary evaluates to true if the difference between the file last modification time and the time find was started, rounded up to the next full 24-hour period, is n 24-hour periods.
If units are specified, this primary evaluates to true if the difference between the file last modification time and the time find was started is exactly n units.
Please refer to the -atime primary description for information on supported time units.
-atime n[smhdw]
If no units are specified, this primary evaluates to true if the difference between the file last access time and the time find was started, rounded up to the nextfull 24-hour period, is n 24-hour periods.
If units are specified, this primary evaluates to true if the difference between the file last access time and the time find was started is exactly n units. Possible time units are as follows:
s second
m minute (60 seconds)
h hour (60 minutes)
d day (24 hours)
w week (7 days)
Any number of units may be combined in one -atime argument, for example, “-atime -1h30m”. Units are probably only useful when used in conjunction with the + or – modifier.
I found an error with vmware esxi. Message from windows client is: Call “HostStorageSystem.ComputeDiskPartitionInfo” for object “storageSystem” on ESXi “x.x.x.x” failed.
I have the issue because the disk that I was using had existing partitions (a Linux swap partition and a Linux MD5 RAID partition). I had to manually delete the partitions logged in as root to my ESXi box, even though ESXi said it would do that for me.
Useful commands:
# esxcfg-scsidevs -l
this lists the disk devices, the device file will be /dev/disks/<NAME>
output looks like:

Easy solution:
Now can recreate partition table for that disk with a blank one:
for MSDOS run:
~ # partedUtil setptbl /dev/disks/naa.600508b1001c95a3d3a1f9455babd2d0 msdos
msdos
0 0 0 0
for HDD larger than 2TB use GPT:
~ # partedUtil setptbl /dev/disks/naa.600508b1001cfb4c4b4ed4e1eee52e25 gpt
gpt
0 0 0 0
Now you have a fresh drive. Try to add again in datastore.
Alternative solution: # partedUtil get /dev/disks/t10.ATA_...
this shows the partitions on the device
output looks like:
38913 255 63 625142448
1 63 514079 130 128
2 514080 625137344 253 0
this disk has 2 partitions, numbers 1 and 2
# partedUtil delete /dev/disks/t10.ATA_... 2
deletes partition 2
# partedUtil delete /dev/disks/t10.ATA_... 1
deletes partition 1
