Seagate 5TB, 估計係Archive碟(疊瓦式)
非必要唔好俾咁多野佢做
好地地點解要full format?

N年前傳承下來的(好/壞)習慣
凡置新碟我自己都習慣 fill 一次才安心

等緊樓主做完白老鼠後來報告用左幾耐至可以完成Format。

作者: idolclub 時間: 2017-7-4 23:34
唔應該行Full format,想睇下成隻碟有冇壞應該用Tools行Full Scan,兼且要可以Mon住佢行到邊同Real Time速度

"係咪有事"
實有事

當佢平均寫入150MB/s,5TB大約9小時多啲啦,2hrs得1%係好慢。

full format 一隻 internal 3TB HD. 我估依個年代無人會咁做. 你還要full format的是一隻external 5TB 的.... USB2.0? USB3.0? eSATA ? 乜OS, 本身個USB port支援高速 device ?
作者: sunyan12 時間: 2017-7-5 02:30
如果USB 3.0 HD 每秒約8XMB...
差吾多係咁多時間喇....

數學題
5000 x 0.01 / 2 / 60 / 60 / 1000 = ~6.95 (MB/s)
<> 5000 x 1000 / 6.95 / 60 /60 = ~199.84hours
假設 USB 3.0 ~ 75MB/s
5000 x 1000 / 75 / 60 / 60 = ~18.5 hours
假設 eSATA ~ 135MB/s
5000 x 1000 / 135 / 60 / 60 = ~10.29 hours
作者: TH30 時間: 2017-7-5 15:50
不一定是linear的
我試過是越寫越慢
不知道是外圈問題還是過熱問題

fill一次都要驚佢死唔死嘅碟不如唔好用

宣佈番 我琴晚已經頂唔順熄左佢
行左次Quick format就開始用
作者: KinChungE 時間: 2017-7-5 20:14
正解
所以唔好買Archive碟
作者: diy-apprentice 時間: 2017-7-6 15:50
咁無耐性點得架!真失望!

我隻WD Gold 10TB full format用左14個鐘多D
作者: rhino 時間: 2017-7-6 16:08
想知full format 嘅目的係乜?
作者: pc1668 時間: 2017-7-6 16:14
How do we know if the hdd is Archive碟 (疊瓦式)?
作者: diy-apprentice 時間: 2017-7-6 16:22
好多時都係心理影響多過實質需要。
作者: rhino 時間: 2017-7-6 16:25
係未好似 N 年前要入BIOS 做 LOW LEVEL FORMAT.
作者: diy-apprentice 時間: 2017-7-6 16:41
而家相信無人再玩Low Level Format啦!我都唔記得點打Command了,

作者: rhino 時間: 2017-7-6 16:45
就算記得都未必搵得番啲硬件

好地地點解要full format? ...
KinChungE 發表於 2017-7-4 11:02 PM
咁慢主要因為格式化係sequential咁寫......
同疊瓦式無關。
作者: KinChungE 時間: 2017-7-6 17:38
正常HDD sequential full erase都唔應該慢得咁緊要
作者: fishhk1213 時間: 2017-7-6 17:40

你 Seagate 5tb 有冇中 bug? 我有一隻中左

ching 係咪單format 一隻計?如果行raid咪仲大鑊?
作者: skydreamer888 時間: 2017-7-7 03:14
係單獨一隻
但RAID應該冇咩太大影響掛,影響時間嘅主要因素係一隻硬碟嘅sequential performance,RAID時係幾隻硬碟一齊
作者: macis 時間: 2017-7-7 10:19
樓主最後用咗幾耐format?
作者: ryanpang 時間: 2017-7-8 22:32
我記得format過一隻2T,用左超過24小時
自此之後買新碟都係快速算了

喺好耐好耐以前嘅硬碟,完全靠硬碟控制卡去控制磁頭去讀寫數據,嗰個年代嘅硬碟上面會有一個出廠壞磁區表,要做Low Level Format嘅時候喺BIOS輸入壞區資料,之後先至可以Format嚟用。
Defects? . . . But Isn't My Drive PERFECT?
No. One of the BIGGEST LIES being told to users of contemporary mass storage systems -- and their operating systems -- is that their drives are "flawless."
THE TRUTH IS that the surfaces of our hard disks are littered with manufacturing variations which adversely affect the surface's ability to retain and represent the data stored there.
Before drives became "intelligent", and able to hide their defective regions, they wore their defects out on their sleeves. The photo below shows a typical RLL drive of that era with a long list of the "known defects" at the time of manufacture.
Why would any manufacturer "advertise" their drive's defects in this manner? Because the purchaser of the drive was required to manually enter this list into the system's low-level formatting program so that the sectors containing those defective spots could be "marked bad" and prevented from ever being used to hold data. As you can imagine, people did not appreciate buying a "new" drive that contained defects. So they'd select the drives with the shortest defect lists, leaving the worst drives for the next guy who didn't know any better.
The instant our drives became intelligent, carrying their own built-in controllers, the very first thing to disappear from the outside of the drive were the defect lists.
An "intelligent" drive's on board brain works to make the drive appear "defect free" by managing a pool of spare sectors and "redirecting" any accesses to the drive's internally defective sectors to the corresponding "reallocated" spare sector. Thus, users all believed that drives became perfect. Also, there was no longer any way to select the "best" drives from the herd. Nor was there any way to tell one manufacturer from another or to know what was really going on inside the drive.

但自從硬碟自已有控制器(硬碟上面嘅CPU)同Firmware開始,之後仲加埋S.M.A.R.T.,就已經無需要做Low Level Format呢樣野,喺出廠之前已經做咗,硬碟自己已經識得做壞區處理,甚至OS完全唔會知道壞區嘅存在。

我 full format 一隻 lacie mini rugged 4T (usb 3.0) 由 09:30 去到 15:30 都有60% ,樓主 兩粒鐘先有 1% 真係好慢
作者: kannet 時間: 2017-7-10 17:44
mac os 十秒唔洗
我都唔明同windows 技術上既分別,唔明點解windows要咁慢
作者: kaxman 時間: 2017-7-10 18:22
Windows 都有快速 format 都好快
而家講緊 full format
請問你呢個 mac os 係咪都係 full format ?

mac os 冇得揀FULL 唔FULL FORMAT
(當轉埋FORMAT 做NTFS,FAT32,EXFAT)
加分埋區都只係多十秒8秒,
如果分得區加埋轉format ,
應該都算full format
如果要去到LOW LEVEL FORMAT,
應該都要幾傷個 HDD

windows 自帶個 formatter 好似有 D 笨,full format 只做 read test 無正式 write 落去...read 到當無事
