    areca raid - convert from MBR to GPT without offlining the raidset(s)?

    but how about GPT-Fdisk: http://mac.softpedia.com/get/System-Utilities/GPT-fdisk.shtml it at least promises to do exactly what i'd like to. anyone have experience on it?

    areca raid - convert from MBR to GPT without offlining the raidset(s)?

    was hoping i'd be able to not do that. but i guess no jive. oh, well.

    areca raid - convert from MBR to GPT without offlining the raidset(s)?

    the raid was originally created with four 1.5Tb drives, and holds two 2.2.Tb MBR partitions - max size for 32bit windows. now that i'm finally on GPT-aware workstations, i would like to expand to a single 9Tb partition that the current four 3Tb drives on the array will accomodate. can i...

    help /w areca raid 5 recovery - 5020 4-bay box, 1 failed HD

    great, houkouonchi! it's now rebuilding after i plugged out / plugged in the new "hot spare" drive. i guess all of this was just a scare and the controller is doing exactly what it should be - but having i guess always previously replaced (failed) drives when the system was powered up, i...

    help /w areca raid 5 recovery - 5020 4-bay box, 1 failed HD

    wow - it's been almost 6 weeks before i'm getting a chance to attempt recovery on this. anyway - houkouonchi - your advice seems solid, thank you. but what, if any, is the risk associated with it? should i clone the HDs before starting to push buttons? activate raid set -dialogue says...

    win7-64 has stopped seeing my 9Tb GPT partition in an areca 5020 raid-box

    ok - all is good now - against high odds. this seems to have been just a scare - caused by asus implementation of usb3 or the bytecc interface dongle. once i got another x64 box up, i was able to see the drive normally. chkdsk found i think one corrupt file, which likely was already there...

    win7-64 has stopped seeing my 9Tb GPT partition in an areca 5020 raid-box

    the initial x64 connection was eSata. have been working on this data for 4 months straight with no hitches. when connecting to the XP box, no error message popped up, just the system didn't see the volume - which, if i recall right, is what i've seen sometime before as well, with no damage...

    win7-64 has stopped seeing my 9Tb GPT partition in an areca 5020 raid-box

    and wants to format it. disk management shows it as "raw." areca web interface shows the volume as "normal" - all seems good. paragon partition manager sees a 189.9Gb partition, as does r-studio, which also sees the directory structure - but i'm afraid of doing anything at all until i'm...

    help /w areca raid 5 recovery - 5020 4-bay box, 1 failed HD

    i'm not sure whether it was degrareded before the shutdown / pull of the drive. my bad. wondering if i should order new HD's to make a sector-by-sector back-up of it all before attempting to do anything else. i'll study the logs / screens and report back with further detail. but that'll likely...

    help /w areca raid 5 recovery - 5020 4-bay box, 1 failed HD

    ok - so i have this 4 hd box with a built-in controller & eSata hookup. i've rebuilt the raid numerous times after replacing individual drives - and learned to trust it. this time around though, once i'd replaced a failed drive (at slot 1), the log says "incomplete raid" discovered and...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    this tale is even more bizarre than i thought - the same arc-5020 box i was posting about before, now hooked via a port multiplier capable jmicron expresscard that lets me see both volumes on it. e.g. - the volume at the heads of the drives U: has the slow reads that i'd complained before...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    this is an external DAS-storage box hooked onto the motherboard ich9m controller on a laptop. so i can't get to the bootup screen of the controller card, nor do i know what the chip actually is, but it's made by areca. i do get marginally more speed in the same hook-up with a 2 HD raid0 stripe...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    thanks for the graph - i like the throughput it shows - gotta get another 16 drives, i guess. surprisingly the access time doesn't get any better with the amount of drives, though. meanwhile, see, in my situation the standard hdTune benchmark is NOT off at all, just the file benchmark. the...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    yes, the 1st volume on the box is "short-stroked" as you describe. is there a hit caused by NTFS on top of the one caused by the slower drive tails, which we both figure is not the issue here? if - what causes that? my volume is 95% full, but it is NOT fragmented at all - i run overnight...

    ARECA Owner's Thread (SAS/SATA RAID Cards)

    i'm aware of the parity / redundancy consideration between the different raid levels. went for 10 as it IS more robust & this is data that i can't afford to lose. can you shed some light on why it would be so much slower when full? i don't conceptually understand what could be going on. on...
